SPECIFIC USE DIRECTIONS 

Solem Diquat Landscape and Aquatic Herbicide is a nonvolatile herbicidal chemical for use as a general 

herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, 

bulbs, etc. except in the state of California); landscape, industrial, recreational, commercial, residential, and 

public areas; turf renovation (all turf areas except commercial sod farms); dormant established turfgrass 

(bermudagrass, zoysiagrass, nonfood or feed crop); and aquatic areas. Absorption and herbicidal action is 

usually quite rapid with effects visible in a few days. Solera Diquat Landscape and Aquatic Herbicide 

controls weeds by interfering with photosynthesis within green plant tissue. Weed plants should be 

succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after use. 

Avoid spray drift to crops, ornamentals, and other desirable plants during application, as injury may result. 

Application to muddy water may result in reduced control. Minimize creating muddy water during 

application. Use of dirty or muddy water for Solera Diquat Landscape and Aquatic Herbicide dilution may 

result in reduced herbicidal activity. Avoid applying under conditions of high wind, water flow, or wave 

action. 

SPRAY DRIFT MANAGEMENT 

AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE 

APPLICATOR AND THE GROWER. The interaction of many equipment and weather related factors 

determine the potential for spray drift. The applicator and the grower are responsible for considering all 

there factors hen making decisions, 

The following drift management requirements must be followed to avoid off·target drift movement from 

aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications suing dry fOlwulations: 

• Tire distance of the outermost nozzles on the boom must not exceed 'X the length of the wingspan 

or rotor. 

• Nozzles must always point backward parallel with the air stream and never be pointed downward 

more than 45 degrees. 

Where states have more stringent regulations, they must be observed. 

DROPLET SIZE: 

The most effective ay to reduce drift potential is to apply large droplets. The best drift management 

strategy is to apply the largest droplets that provide sufficient coverage and control. Applyjj}g larger 

droplets reduces drift potential, but wiIl not prevent drift if applications are made improperIy;or under 

unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions 

sections of the label). 

CONTROLLING DROPLET SIZE: 

Volume~ Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher 

rated flows produce larger droplets. 

Pressure ~ Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle types, 

lower pressure produces larger droplets. When bigher flow rates are needed, use higher flow rate nozzles 

instead of increasing pressure. 

Num ber of Nozzles ~ Use the minimum number of nozzles that provide unifonn coverage. 

Nozzle Orientation ~ Orienting nozzles so that the spray is released parallel to the air stream produces 

larger droplets than other orientations and is the recommended practice. Significant deflection from 

horizontal will reduce the droplet size and increase drift potential. 
9

page 5 of 10 

Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, 

narrower spay angles produce l,arger droplets. Consider using low-drift nozzles. Solid stream nozzles 

oriented straight back producl

l

the largest droplets and the lowest drift. 

BOOM LENGTH: 

For some use patterns, reduc~g the effective boom length to less than Yo of the wingspan or rotor length 

may further reduce drift withq'ut reducing swath width. 

APPLICATON HIEGHT: 

Applications should not be made at a height greater than 10 feed above the top of the largest plants unless a 

greater height is required for aircraft safety. Making applications at tbe lowest height that is safe reduces 

exposure of droplets to evaporation and wind. 

SWATH ADJUSTMENT: 

When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up 

and downside edges for the field, the applicator must compensate for this displacement by adjusting the 

path of the aircraft upwind. Swath adjustment distance should increase with increasing drift potential 

(higher wind, smaller droplets, etc.). 

WIND: 

Drift potential is lowest between wind speeds of2-1 0 mph. However, many factors, including droplet size 

and equipment type, detennine drift potential at any given speed. Application should be avoided below 2 

mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence wind 

patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. 

TEMPERATURE AND HUMIDITY: 

When making applications in low relative humidity, set up equipment to produce larger droplets to 

compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

TEMPERATURE INVERSIONS: 

Applications should not occur during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which causes small-suspended droplets to remain in a concentrated 

cloud. This cloud can move in unpredictable directions due to the light variable winds common during 

inversions. Temperature inversions are characterized by increasing temperatures with altitude and are 

common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and 

often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not 

present, inversions can also be identified by the movement of smoke from a ground source or an aircraft 

smoke generator. Smoke that layers and moves laterally in a concentrated cloud (lUleier low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates, indicates good 

vertical air mixing. 

SENSITIVE AREAS: 

The pesticide should only be applied when the wind is blowing away from adjacent sensitive areas (e.g. 

residential areas, bodies of water, known habitat for threatened or endangered species, non~target crops). 

COMMERCIAL GREENHOUSES AND NURSERIES 

For general weed control in commercial greenhouses (beneath bencbes), field grown and container stock, 

and other similar areas, Solera Diquat Landscape and Aquatic Herbicide may be applied preplant or 

postplant preemergence in field gro"WIl. ornamental nursery plantings or postemergence as a directed spray. 

Solera Diquat Landscape and Aquatic Herbicide may also be applied preemergence in ornamental seed 

crops (except in the state ofCaIifornia). Avoid contact with desirable foliage as injury may occur. Do not 

use on food or feed crops. 

Spot spray: 1-2 qts. Solera Diquat Landscape and Aquatic Herbicide plus the labeled rate of a 75% or 

greater nonionic surfactant per 100 gals. of water, or 0.75 oz. (22 mls.) Solera Diquat Landscape and 

Aquatic Herbicide plus the labeled rate of a 75% or greater nonionic surfactant per 1 gal. of water.

DIRECTIONS FOR LANDSCAPE, INDUSTRIAL, RECREA TlONAL, COMMERCIAL, 

RESIDENTIAL, AND PUBLIC AREAS 

Solera Diquat Landscape and Aquatic Herbicide provides fast control of broad leaf and grassy weeds in 

industrial, recreational, golf course, commercial, residential, and public areas. 

Solera Diquat Landscape and Aquatic Herbicide is a nonselective herbicide that rapidly kills undesirable 

above ground weed growth in 24-36 hours. A void application of Solera Diquat Landscape and Aquatic 

Herbicide to desirable plants. 

Solera Diquat Landscape and Aquatic Herbicide is a contact/desiccant herbicide; it is essential to obtain 

complete coverage of the target weeds to get good control. Improper application technique and/or 

application to stressed weeds may result in unacceptable weed control. For best results, apply to actively 

growing, young weeds. 

Difficult weeds (such as perennial or deeply-rooted weeds) can often be controlled by tank mixing Solera 

Diquat Landscape and Aquatic Herbicide with other systemic-type herbicides. Refer to other product labels 

for specific application directions. 

For residual weed control, tank mix Solera Diquat Landscape and Aquatic Herbicide with a preemergent 

herbicide labeled for the intended use site. When mixing Solera Diquat Landscape and Aquatic Herbicide 

with another herbicide, it is recommended to mix just a small amount first to determine if the mixture is 

physically compatible before proceeding with larger volumes. 

Source Dynamics, LLC has not tested all possible tank mixtures with other herbicides for compatibility, 

efficacy or other adverse effects. Before mixing with other herbicides Source Dynamics, LLC recommends 

you first consult your state experimental station, state university or extension agent 

Grounds maintenance weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a 

spot or broadcast spray to control weeds in public, commercial and residential landscapes, including 

landscape beds, lawns, golf courses and roadsides. Solera Diquat Landscape and Aquatic Herbicide can 

also be used for weed control around the edges and nonflooded portions of ponds, lakes and ditches. 

Trim and Edge weed control: Solera Diquat Landscape and Aquatic Herbicide can be used to eliminate 

undesired grass and broad leaf plant growth in a narrow band along driveways, walkways, patios, cart paths, 

fence lines, and around trees, ornamental gardens, buildings, other structures, and beneath noncommercial 

greenhouse benches. Vegetation control with Solera Diquat Landscape and Aquatic Herbicide is limited to 

the spray application width. Do not exceed the labeled rate of Soler a Diquat Landscape and Aquatic 

Herbicide as excessive rates may result in staining of concrete-based materials. 

Solera Diquat Landscape and Aquatic Herbicide, since it does not translocate systemically, can be used as 

an edging or pruning tool when precisely applied to select areas of grass or to undesirable growth on 

desirable ornamental bedding plants, ground covers, etc. 

Industrial weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a spot or 

broadcast spray either alone or in combination with other herbicides as a fast burndown or control weeds in 

rights-of-ways, railroad beds/yards, highways, roads, dividers and medians, parking lots, pipelines, 

pumping stations, public utility lines, transfonner stations and substations, electric utilities, storage yards, 

and other non-crop areas. 

Spot spray: Apply either 1-2 qts. of Soler a Diquat Landscape and Aquatic Herbicide plus the labeled rate 

of a 75% or greater nonionic surfactant per 100 gals. water, or 0.75 oz. (22 mls.) Solera Diquat Landscape 

and Aquatic Herbicide plus the labeled rate of a 75% or greater nonionic surfactant per I gal. of water. 

Broadcast: 1-2 pts. Solera Diquat Landscape and Aquatic Herbicide per acre in sufficient water to insure 

good spray coverage. Add the labeled rate of 75% or greater nonionic surfactant per 100 gals. spray 

mixture. Greater water volumes are necessary if the target plants are tall and/or dense. It is recommended 

that 60 gals. or greater water volume be used to obtain good coverage of dense weeds. 

TURF RENOVATION (ALL TURF AREAS EXCEPT COMMERCIAL SOD FARMS) 

To desiccate golf course turf and other turf areas prior to renovation, apply 1-2 pts. of Solera Diquat 

Landscape and Aquatic Herbicide per acre plus the labeled rate of a 75% or greater nonionic surfactant in 

20-100 gals. of water (4 teaspoons of Sol era Diquat Landscape and Aquatic Herbicide plus the labeled rate 
11

I 

page7of1Q 

of a 75% or greater nonionic sUifactant per I gal. afwater) using ground spray equipment. Apply for full 

coverage and thorough contact with the turfgrass. Apply only when the turf is dry, free from dew and 

incidental moisture. For enhanced turf desiccation, especially in the case of thick turf grass, water volumes 

should approach 100 gals. afwater per acre. 

For suppression of regrowth and quick desiccation of treated tutigrass, Solera Diquat Landscape and 

Aquatic Herbicide may be mixed with other systemic nonselective or systemic postemergence grassy weed 

herbicides. Refer to other product labels for specific application directions and restrictions. 

A void spray contact with, or spray drift to, foliage of ornamental plants or food crops. 

Do not graze livestock on treated turf or feed treated thatch to livestock. 

DORMANT ESTABLISHED TURFGRASS (BERMUDAGRASS, WYSlAGRASS), NONFOOD OR 

FEED CROP 

For control of emerged annual broad leaf and grass weeds, including Little Barley", Annual Bluegrass, 

Bromes including Rescuegrass, Sixweeks fescue, Henbit, Buttercup, and Carolina Geranium in established 

donnant bermudagrass lawns, parks, golf courses, etc. 

Apply 1-2 pts. Solera Diquat Landscape and Aquatic Herbicide per acre in 20-1 00 gals. of spray mix by 

ground as a broadcast application. Add the labeled rate of a 75% or greater nonionic surfactant per 100 

gals. of spray mixtUl"e. 

Bennudagrass must be dormant at application. Application to actively growing beffi1udagrass may cause 

delay or pennanent injury. Users in the extreme Southern areas should be attentive to the extent of 

dormancy at the time of application. 

*For control of Little Barley, apply Solera Diquat Landscape and Aquatic Herbicide prior to the mid-boot 

stage. 

AQUATIC USE DIRECTIONS 

New Yorl' - Not for Sale or Use in New York State without Supplemental Special Local 

Needs Labeling. 

Necessary approval andlor pennits must be obtained prior to application if required. Consult the 

responsible State Agencies (Le., Fish and Game Agencies, State Water Conservation authorities, or 

Department ofNamral Resources). 

Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of 

oxygen may cause fIsh suffocation. Therefore, treat only 1/3 to 112 ofthe water body area at one time and 

wait 14 days between treatments. 

For best results on submersed weeds, Solera Diquat Landscape and Aquatic Herbicide should be applied to 

actively growing (photosynthesizing) weeds when water temperatures have reached or exceeded 

approximately 50°F, typically during the Spring or early Summer. 

For application only to still water (i.e. ponds, lakes, and drainage ditches) where there is minimal or no 

outflow to public waterS. 

and/or 

For applications to public waters in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, canals, 

sh'eams, rivers, and other slow-moving or quiescent bodies of water for control of aquatic weeds. For use 

by: 

• Corps of Engineers; or 

o Federal or State Public Agencies (I.e., Water Management District personnel, municipal officials); 

" • Applicators and/or Licensees (certifIed for aquatic pest control) that are authorized by the State or 

Local govemment. 

Treated water may be used according to the following table or until such time as an approved assay 

(example: PAM II Spectromatic Method) shows that the water does not contain more than the designated 

maximum contaminant level goal (MCLG) of 0.02 mg/1. (ppm) of diquat dibromide (calculated as the

andlor State authorities must be obtained. 

Floating and Marginal Weeds Including: 

Water lettuce, Pistia stratiotes 

Water hyacinth, Eichhornia crassipes 

Duckweed, Lemna spp. 

Salvinia spp. (including S. molesta) 

Pennywort (Hydrocotyle spp.) 

Frog's Bie, Limnobium spong;a 

Cattails, Typha spp. 

'Not for use in California 

Solera Diquat Landscape and Aquatic Herbicide may be applied by backpack, airboat, spray handgun, 

helicopter, airplane, or similar application equipment that results in thorough spray coverage. 

Spot Treatment: Apply Solera Diquat Landscape and Aquatic Herbicide at 2 quarts per 100 gallons spray 

carrier (0.5% solution) with an approved aquatic wetting agent at 0.25-1.0% vlv (I quart to I gallon per 100 

gallons water). For cattail control, Solera Diquat Landscape and Aquatic Herbicide should be applied prior 

to flowering at the maximum application rate (8 quarts of Solera Diquat Landscape and Aquatic 

Herbicide/ I 00 gallons spray carrier) plus the wetting agent. Repeat treatments may be necessary for 

complete control. 

Spray to completely wet target weeds but not to runoff. Densely packed weeds or mats may require 

additional applications due to incomplete spray coverage. Re·treat as needed. For best results, retreat weed 

escapes within 2 weeks ofthe initial treatment. 

Broadcast Treatment: Apply Solera Diquat Landscape and Aquatic Herbicide at the rate of 0.5·2.0 

gallons per surface acre in sufficient carrier along with 16-32 oz.lA of an approved wetting agent. Re·treat 

as necessary for densely populated weed areas. Good coverage is necessary for control of the target weeds. 

For duckweed control, apply Solera Diquat Landscape and Aquatic Herbicide at 1·2 gaiJonslA. 

Submersed Weeds Including: 

Bladderwort, Utricular;a spp. 

Hydrilla, Hydrilla verticil/ata 

Watennilfoils (including Eurasian), Myriophyllum spp.

iSolera Diquat Landscape and Aquatic Herbicide controls Potamogetan species except Richardson's 

pondweed, P. richardSOl1ii. 

2Suppression only. For control of Spirogyra andlor Pithophora, use Solera Diquat Landscape and Aquatic 

Herbicide in a tank mix with an approved algaecide. 

For severe weed or algae infestations, the use afan approved algaecide either as a pretreatment to the 

Solera Diquat Landscape and Aquatic Herbicide application or in a tank mix, may result in enhanced weed 

controL 

To control submersed weeds, apply Solera Diquat Landscape and Aquatic Herbicide in water at O.5~2.0 

gallons per surface acre (per 4 foot water depth), For severe weed infestations, use the 2.0 gallon per 

surface acre rate, For best results, re~treat as necessary on 14-21 day intervals. The table below shows how 

many gallons of Soler a Diquat Landscape and Aquatic Herbicide to apply per sUlface acre based on water

Subsurface Applications: Where the submersed weed growth, especially Hydrilla, has reached the water 

surface, apply either in a water carrier or an invert emulsion through boom trailing hoses carrying nozzle 

tips to apply the dilute spray below the water surface to insure adequate coverage. 

Bottom Placement: Where submersed weeds such as Hydrilla, Bladderwort, or Coon tail have reached the 

water surface and/or where the water is slowly moving through the weed growth, the use of an invert 

emulsion carrier injecting diluted Solera Diquat Landscape and Aquatic Herbicide near the bottom with 

weighted hoses may improve control. The addition ofa copper based algaecide may improve control. If 

algae are present along with the submersed weeds, a pretreatment with a copper based algaecide may 

improve overall control. 

Surface Application for Submerged Aquatic Weeds: Apply the recommended rate of Soler a Diquat 

Landscape and Aquatic Herbicide as a spray in sufficient carrier to fully cover the target area. Applications 

should be made to ensure complete coverage of the weed areas. In mixed weed populations, use the high 

rate of application as indicated by weeds present. For dense submersed weeds or water over 2 feet deep, a 

surface spray is not recorrrrnended (Solera Diquat Landscape and Aquatic Herbicide should be applied 

subsurface in these situations.) 

If posting is required by your state or tribe ~ consult the agency responsible for pesticide regulations

Attn.: K3thryn Montague (PM 23), Herbicide Branch, Registration Division 

Dear Ms. Montague: 

Subject: Diguat Formulations: 82542- t4 and 82542-t5: Signal Word 

Thank you for your e-mail today. I now see the problem, and I believe that there is a simple 

solution. Our Data Matrices for these two products of identical composition referenced an acute 

oral toxicity study for a 41 % manufacturing--use product, not for a 37.3% end--use material. The 

Category II classification of this study was noted by the Technical Review Branch in a 

memorandum dated April 9, 2009 {DP Barcode D360710, Decision No. 404346J, but Source 

Dynamics LLC failed to observe it The remaining acute toxicity studies that were referenced 

support a Category III classification. 

The problematic·acute oral toxicity study that we referenced is as follows: 

MRID 47099012 

Patani, K (2007) Acute Oral Toxicity Study of Dlquat Dibromicle Tech 4 t Percent in Rals. Project

Therefore Source Dynamics LLC wishes to reference an acute oral toxicity study for a 37.3% 

(3.73 pound per gallon) end-use formulation instead. This study is as follows:

The only speciflC reference change from the preVious data matrices Is for the acute oral toxIcIty 

study, Guideline 870.1100. The generic references have also been updated In conformity wIth 

the March 31, 2010 Pesticide Data Submitters List. The acute oral toxicity study now referenced 

is itself no longer compensable. 

Once again, thank you for bnnging this to our attention. We apologize for the confusion. 

Sincerely,

Subject: ~Solera Diquat Landscape and Aquatic Herbicide (82542-14) 

Solera Diquat 2L Desiccant (82542-15) 

Signal Word 

These two products are of identical composition and consist simply of a 37.3% 

w/w solution of diquat dibromide in Source Dynamics LLC in our 

registration applications for these products submitted to the Agency draft labels 

wtth the signal word Caution. However, the Notices of Pesticide Registration 

dated May 14, 2009 advised us to change the signal word to Warning. No 

explanation was provided regarding the rationale for this change. Source 

Dynamics LLC complied with this request when final printed labels were 

submitted on June 13, 2009. 

We have since noted, however, that this year the Agency has approved many 

other essentially identical 37.3% diquat dibromide formulations in which the 

signal word Caution was approved without comment. These Agency actions 

include the following: 

Tel. 480.502.9289

Aceto Diquat Dibromide 37.3% SL Ag (2749-530; (2749-532; Aceto 

Agricultural Chemicals Corp.) in November 2009 

In view of these observations, we have concluded that the Agency's instruction to 

change the signal word to Caution to Warning on our two virtually identical 

products must have been in erroL 

Therefore we ask the Agency to amend the signal word on our products from 

Warning back to Caution. Please find enclosed EPA Form 8570-1 and five 

copies of the amended label for each product. The labels, with the exception of 

the signal word, are identical to the final labels submitted on June 13, 2009. 

We believe that these are administrative actions only; no new technical data are 

required or cited to support these proposals. 

Sincerely, 

Rufus Bastian, President

Footnotes 

A During the 21 day initial content review, all CSFs will be reviewed to determine 

whether all inerts listed, including fragrances, are approved for the proposed uses. If an 

unapproved inert is identified, the applicant must either 1) resolve the inert issue by, for 

example, removing the inert, substituting it with an approved inert, submitting 

documentation that EPA approved the inert for the proposed pesticidal uses, correcting 

mistakes on the CSF, etc. or 2) provide the data to support OPP approval of the inert or 3) 

withdraw the application. Removing or substituting an inert ingredient will require a new 

CSF and may require submission of data. All information, fOTIns, data and 

documentation resolving the inert issue must have been received by the Agency or the 

application withdrawn within the 21 day period. otherwise, the Agency will reject the 

application as described below. 

To successfully complete this aspect of the 21 day initial content screen, applicants are 

strongly encouraged to verify that all inert ingredients have been approved for the 

application's uses even if a product is currently registered by consulting the inert Web 

3 
49

! 

site [link to http://www.epa.gov/opprdOOl/inerts/lists.html] and if the inert is not 

approved, to obtain the necessary inert approval prior to submitting an application 

to register a pesticide product containing that inert ingredient. Some inert 

ingredients are no longer approved for food uses or certain types of uses. The name 

and/or CAS number on a CSF must match the name and CAS number on this web site. 

Simple typographical errors in the name or CAS number have resulted in processing 

delays. 

If an inert is not listed on the inert ingredient web site and the applicant believes that the 

inert has been approved, the applicant should contact the Inert Ingredient Assessment 

Branch (IIAB) at inertsbranch@epa.gov and resolve the issue. Copies of the 

correspondence with HAB resolving the issue should accompany the application. All 

new inerts except PIP inerts are reviewed by lIAB. The IIAB should also be contacted 

for any questions on what supporting data needs to be submitted for and the Agency's 

inert review process. Questions on PIP inerts should be directed to the Chief of 

Microbial Pesticides Branch [Link to 

http://www.epa.gov/oppbppdIlbiopesticides/contacts bppd.htm J. 

When a brand, trade, or proprietary name of an inert ingredient is listed on a CSF, 

additional information such as an alternate name of the inert, CAS number or other 

information [link to http://www.epa.gov/opprdOOllinerts/tips.pdfJ must also be included 

to enable the Agency to determine if it has been approved. Each component of an inert 

mixture (including a fragrance) must be identified. In some cases, the supplier of the 

mixture or fragrance may need to provide this information to the Agency. Prior to the 

Agency's receipt of an application, applicants must arrange with a proprietary mixture or 

fragrance supplier to provide the component information to the Agency or promptly upon 

EPA's request. If the inert ingredients in a proprietary blend (including fragrances) 

cannot or are not identified or provided within the 21-day content review period, the 

Agency will reject the application. 

During the 21 day content review, applicants should submit information to the individual 

identified by the Agency when the applicant is informed of an unapproved inert, 

Unapproved Inerts Identified on CSFs 

All applications except conventional new products and -PIPs 

Once an llllapproved inert is identified on a eSF, the Agency will contact the 

applicant with the following options'. 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the infonnation and data needed for the Agency to approve the 

unapproved inert. If this option is selected and implemented, the Agency may 

request an extension in the PRIA decision review timeframe to accommodate 

the inert review/approval process; 

4 
50

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of these options is selected and implemented by the applicant within the 

21 day content review period, the Agency will reject the application and retain 

25% of the full fee ofthe category identified. 

C~nventional New Product Applications 

When the Registration Division identifies an unapproved inert on a CSF with an 

application for a new-product that the applicant has not identified as requiring an 

inert approval (R3Il, R3l2 or R313), it will contact the applicant with the 

following options: 

1. Correct the application by, for instance, correcting the inert's identity or CAS 

number, providing documentation that the inert has been approved, or 

removing the unapproved inert from the CSF or replacing it with one that is 

approved for the application's uses; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert, including any required petition to establish or amend a 

tolerance or exemption from a tolerance. (This option may change the PRIA 

category for the application, which could require a longer decision review 

time and a larger fee. If additional fees are due, they must be received by the 

Agency within the 21 day content review period.) 

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

If none of the above options is selected and implemented during the 21 -day 

content-review period, the Agency will reject the application and retain 25% of 

the appropriate fee for the new product-inert approval category. 

PIP Applications 

When the Biopesticide and Pollution Prevention Division identifies an 

unapproved inert on a PIP CSF and a request to approve the inert does not 

accompany the application, it will contact the applicant with the following 

options: 

1. Correct the application by, for instance, correcting the spelling or name of the 

inert to that in 40 CFR 174, or providing documentation that the inert has been 

approved; or 

2. Submit the information and data needed for the Agency to approve the 

unapproved inert. If an inert ingredient tolerance exemption petition is 

required, the petition must be received by the Agency and the B903 fee paid 

within the 21 day period. If this option is selected and implemented, the 

Agency will discuss harmonizing the timeframe for both actions. 

5 
51

3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

Ifnone of the above options is selected and implemented during the 21 day 

content review period, the Agency will reject the application and retain 25% of 

the fee. 

B. A policy on documentation of offers to pay is still being developed, however, for a 

me~too or fast track (similar/identical) new product, R300 or A530, an application 

without the necessary authorizations of offers to pay will be placed into either R301 or 

A531. The Agency recommends that authorizations of offers to pay be submitted with 

other PRIA applicati.ons to avoid delays in the Agency's decision. 

C. Biopesticide applicants are advised to contact the Agency and discuss study waivers 

prior to submitting their application to the Agency. Documentation of such discussions 

should be submitted with the study waiver.

SPECIFIC USE DIRECTIONS 

Solera Diquat Landscape and, Aquatic Herbicide is a nonvolatile herbicidal chemical for use as a general 

herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, 

bulbs, etc. - except in the state of California); landscape, industrial, recreational, commercial, residential, 

and public areas; turf renovation (all turf areas except conunercial sod farms); dormant established 

turfgrass (bermudagrass, zoysiagrass - nonfood or feed crop); and aquatic areas. Absorption and herbicidal 

action is usually quite rapid with effects visible in a few days. Solera Diquat Landscape and Aquatic 

Herbicide controls weeds by interfering with photosynthesis within green plant tissue. Weed plants should 

be succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after 

use. Avoid spray drift to crops, ornamentals, and other desirable plants during application, as inju!)' may 

result. Application to muddy water may result in reduced control. Minimize creating muddy water during 

application. Use of dirty or muddy water for Solera Diquat Landscape and Aquatic Herbicide dilution may 

resuh in reduced herbicidal activity. A void applying under conditions of high wind, water flow, or wave 

action. 

SPRAY DRIFT MANAGEMENT 

AVOIDING SPRAY DRIFT AT THE APPLICA nON SITE IS THE RESPONSIBILITY OF THE 

APPLICATOR AND THE GROWER. The interaction of many equipment¥and¥weather related factors 

detennine the potential for spray drift. The applicator and the grower are responsible for considering all 

there factors hen making decisions. 

The following drift management requirements must be followed to avoid off¥target drift movement from 

aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications suing dry formulations: 

• The distance of the outennost nozzles on the boom must not exceed:y.. the length of the wingspan 

or rotor. 

• Nozzles must always point backward parallel with the air stream and never be pointed downward 

more than 45 degrees. 

Where states have more stringent regulations, they must be observed. 

DROPLET SIZE: 

The most effective ay to reduce drift potential is to apply large droplets. The best drift management 

strategy is to apply the largest droplets that provide sufficient coverage and control. Applying larger 

droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under 

unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions 

sections of the label). 

CONTROLLING DROPLET SIZE: 

Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher, ' , ;' , 

rated flows produce larger droplets. . , , , , , ' , , 

Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many :hozZle~es, 

lower pressure produces larger droplets. When higher flow rates are needed, use higher flow t:at~ nozzl~s, " 

instead of increasing pressure. ' , : ' , ; " , , Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage. ) , 0' ,> Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the air streamprC'.duces 

larger droplets than O1her orientations and is the recommended practice. Significant deflect;,(>u,ftom 

horizontal will reduce the droplet size and increase drift potential. ", , 

" I' 

", , 
60

page 5 of 10 

Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, 

narrower spay angles produce larger droplets. Consider using low~drift nozzles. Solid stream nozzles 

oriented straight back produce the largest droplets and the lowest drift. 

BOOM LENGTH: 

For some use patterns, reducing the effective boom length to less than Y.. of the wingspan or rotor length 

may further reduce drift without reducing swath width. 

APPLICATON HIEGHT: 

Applications should not be made at a height greater than 10 feed above the top of the largest plants unless a 

greater height is required for aircraft safety. Making applications at the lowest height that is safe reduces 

exposure of droplets to evaporation and wind. 

SWATH ADJUSTMENT: 

When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up 

and downside edges for the field, the applicator must compensate for this displacement by adjusting the 

path of the aircraft upwind. Swath adjustment distance should increase with increasing drift potential 

(higher wind, smaller droplets, etc.). 

WIND, 

Drift potential is lowest between wind speeds of2~10 mph. However, many factors, including droplet size 

and equipment type, determine drift potential at any given speed. Application should be avoided below 2 

mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence wind 

patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. 

TEMPERATURE AND HUMIDITY: 

When making applications in low relative humidity, set up equipment to produce larger droplets to 

compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

TEMPERATURE INVERSIONS: 

Applications should not occur during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which causes smalI~suspended droplets to remain in a concentrated 

cloud. This cloud can move in unpredictable directions due to the light variable winds common during 

inversions. Temperature inversions are characterized by increasing temperatures with altitude and are 

common on nights with limited cloud cover and light to no wind. They begin to fonn as the sun sets and 

often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not 

present, inversions can also be identified by the movement of smoke from a ground source or an aircraft 

smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates, indicates good 

vertical air mixing. 

SENSITIVE AREAS: 

The pesticide should only be applied when the wind is blowing away from adjacent sensitive areas (e.g. 

residential areas, bodies of water, lrnown habitat for threatened or endangered species, non~target crops). 

COMMERCIAL GREENHOUSES AND NURSERIES 

For general weed control in commercial greenhouses (beneath benches), field grown and container stock, 

and other similar areas, Solera Diquat Landscape and Aquatic Herbicide may be applied preplant or

DIRECTIONS FOR LANDSCAPE, INDUSTRIAL, RECREATIONAL, COMMERCIAL, 

RESIDENTIAL, AND PUBLIC AREAS 

Solera Diquat Landscape and Aquatic Herbicide provides fast control of broad leaf and grassy weeds in 

industrial, recreational, golf course, commercial, residential, and public areas. 

Solera Diquat Landscape and Aquatic Herbicide is a nonselective herbicide that rapidly kills undesirable 

above ground weed growth in 24-36 hours. A void application of Solera Diquat Landscape and Aquatic 

Herbicide to desirable plants. 

Solera Diquat Landscape and Aquatic Herbicide is a contact/desiccant herbicide; it is essential to obtain 

complete coverage of the target weeds to get good control. Improper application technique and/or 

application to stressed weeds may result in unacceptable weed control. For best results, apply to actively 

growing, young weeds. 

Difficult weeds (such as perennial or deeply-rooted weeds) can often be controlled by tank mixing Solera 

Diquat Landscape and Aquatic Herbicide with other systemic-type herbicides. Refer to other product labels 

for specific application directions. 

For residual weed control, tank mix Solera Diquat Landscape and Aquatic Herbicide with a preemergent 

herbicide labeled for the intended use site. When mixing Solera Diquat Landscape and Aquatic Herbicide 

with another herbicide, it is recommended to mix just a small amount fIrst to determine ifthe mixture is 

physically compatible before proceeding with larger volumes. 

Source Dynamics, LLC has not tested all possible tank mixtures with other herbicides for compatibility, 

efficacy or other adverse effects. Before mixing with other herbicides Source Dynamics, LLC recommends 

you fIrst consult your state experimental station, state university or extension agent. 

Grounds maintenance weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a 

spot or broadcast spray to control weeds in public, commercial and residential landscapes, including 

landscape beds, lawns, golf courses and roadsides. Solera Diquat Landscape and Aquatic Herbicide can 

also be used for weed control around the edges and nonflooded portions of ponds, lakes and ditches. 

Trim and Edge weed control: Solera Diquat Landscape and Aquatic Herbicide can be used to eliminate 

undesired grass and broadleaf plant growth in a narrow band along driveways, walkways, patios, cart paths, 

fence lines, and around trees, ornamental gardens, buildings, other structures, and beneath nonconunercial 

greenhouse benches. Vegetation control with Solera Diquat Landscape and Aquatic Herbicide is limited to 

the spray application width. Do not exceed the labeled rate of Solera Diquat Landscape and Aquatic 

Herbicide as excessive rates may result in staining of concrete-based materials. 

Solera Diquat Landscape and Aquatic Herbicide, since it does not trans locate systemically, can be used as 

an edging or pruning tool when precisely applied to select areas of grass or to undesirable growth on 

desirable ornamental bedding plants, ground covers, etc. 

Industrial weed control: SoleraDiquat Landscape and Aquatic Herbicide can be used as a spot or 

broadcast spray either alone or in combination with other herbicides as a fast burndovm or control weeds in 

rights-of-ways, railroad bedslyards, highways, roads, dividers and medians, parking lots, pipelines, 

pumping stations, public utility lines, transformer stations and substations, electric utilities, storage yards, 

and other non-crop areas.

AQUATIC USE DIRECTIONS 

New York ~ Not for Sale or Use in New York State without Supplemental Special Local 

Needs Labeling. 

Necessary approval and/or permits must be obtained prior to application if required. Consult the 

responsible State Agencies (i.e., Fish and Game Agencies, State Water Conservation authorities, or 

Department of Natural Resources). 

Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of 

oxygen may cause fish suffocation. Therefore, treat only 1/3 to 112 of the water body area at one time and 

wait 14 days between treatments. 

For best results on submersed weeds, Solera Diquat Landscape and Aquatic Herbicide should be applied to 

actively growing (photosynthesizing) weeds when water temperatures have reached or exceeded 

approximately 50°F, typically during the Spring or early Summer.

Subsurface Applications: Where the submersed weed growth, especially Hydrilla, has reached the water 

surface, apply either in a water carrier or an invert emulsion through boom trailing hoses canying nozzle 

tips to apply the dilute spray below the water surface to insure adequate coverage. 

Bottom Placement: Where submersed weeds such as Hydrilla, Bladderwort, or Coontail have reached the 

water surface and/or where the water is slowly moving through the weed growth, the use of an invert 

emulsion carrier injecting diluted Solera Diquat Landscape and Aquatic Herbicide near the bottom with 

weighted hoses may improve control. The addition of a copper based algaecide may improve control. If 

algae are present along with the submersed weeds, a pretreatment with a copper based algaecide may 

improve overall control. 

Surface Application for Submerged Aquatic Weeds: Apply the recommended rate of Sol era Diquat 

Landscape and Aquatic Herbicide as a spray in sufficient carrier to fully cover the target area. Applications 

should be made to ensure complete coverage of the weed areas. In mixed weed populations, use the high 

rate of application as indicated by weeds present. For dense submersed weeds or water over 2 feet deep, a 

surface spray is not recommended (Solera Diquat Landscape and Aquatic Herbicide should be applied 

subsurface in these situations.)

SPECIFIC USE DIRECTIONS 

Solera Diquat Landscape and Aquatic Herbicide is a nonvolatile berbicidal chemical for use as a general 

herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, 

bulbs, etc. - except in the state of Cali fomi a); landscape, industrial, recreational, commercial, residential, 

and public areas; turf renovation (all turf areas except commercial sod fanns); dormant established 

turfgrass (bermudagrass, zoysiagrass - nonfood or feed crop); and aquatic areas. Absorption and herbicidal 

action is usually quite rapid with effects visible in a few days. Solera Diquat Landscape and Aquatic 

Herbicide controls weeds by interfering with photosynthesis within green planttissue. Weed plants should 

be succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after 

use. A void spray drift to crops, ornamentals, and other desirable plants during application, as injury may 

result. Application to muddy water may result in reduced control. Minimize creating muddy water during 

application. Use of dirty or muddy water for Solera Diquat Landscape and Aquatic Herbicide dilution may 

result in reduced herbicidal activity. Avoid applying under conditions ofbigh wind, water flow, or wave 

action. 

SPRAY DRIFT MANAGEMENT 

AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE 

APPLICATOR AND THE GROWER. The interaction of many equipment-and-weather related factors 

determine the potential for spray drift. The applicator and the grower are responsible for considering all 

there factors hen making decisions. 

The following drift management requirements must be followed to avoid off-target drift movement from 

aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications suing dry fonnulations: 

• The distance of the outermost nozzles on the boom must not exceed % the length of the wingspan 

or rotor. 

• Nozzles must always point backward parallel with the air stream and never be pointed downward 

more than 45 degrees. 

Where states have more stringent regulations, they must be observed. 

DROPLET SIZE: 

The most effective ay to reduce drift potential is to apply large droplets. The best drift management 

strategy is to apply the largest droplets tbat provide sufficient coverage and control. Applying larger 

droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under 

unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions 

sections of the label). 

CONTROLLING DROPLET SIZE: 

Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher 

rated flows produce larger droplets. 

Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle type~,' •• : , 

lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate no"'?les , 

instead of increasing pressure. , , , , . , :' , , 

Numher of Nozzles - Use the minimum number of nozzles that provide uniform coverage.; ~ 

Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the air stteam produces, , 

larger droplets than other orientations and is the recommended practice. Significant defl'ecMrl from ~ >. > ' 

horizontal will reduce the droplet size and increase drift potential. ' , , ' ~ > , , 

Nozzle Type - Use a nozzle type that is designed for the intended application. With mo:;tno;;:,z!e types;, , , 

narrower spay angles produce larger droplets. Consider using low-drift nozzles. Solid sm:4Ip}Jozzles ' 

oriented straight back produce the largest droplets and the lowest drift. -, , , , 

BOOM LENGTH: ' , , , 

For some use patterns, reducing the effective boom length to less than % of the wingspan or rotor lengtll > , > , 

may further reduce drift without reducing swath width. " , 

APPLICATON HIEGHT: 
73

page 5 of 10 

Applications should not be made at a height greater than 10 feed above the top of the largest plants unless a 

greater height is required for aircraft safety. Making applications atthe lowest height that is safe reduces 

exposure of droplets to evaporation and wind. 

SWATH ADJUSTMENT: 

When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up 

and downside edges for the field, the applicator must compensate for this displacement by adjusting the 

path ofthe aircraft upwind. Swath acljustment distance should increase with increasing drift potential 

(higher wind, smaller droplets, etc.). 

WIND, 

Drift potential is lowest between wind speeds of 2·1 0 mph. However, many factors, including droplet size 

and equipment type, determine drift potential at any given speed. Application should be avoided below 2 

mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence wind 

patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. 

TEMPERATURE AND HUMIDITY: 

When making applications in low relative humidity, set up equipment to produce larger droplets to 

compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

TEMPERATURE INVERSIONS: 

Applications should not occur during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which causes smaU·suspended droplets to remain in a concentrated 

cloud. This cloud can move in unpredictable directions due to the light variable winds corrunon during 

inversions. Temperature inversions are characterized by increasing temperatures with altitude and are 

common on nights with limited cloud cover and light to no wind. They begin to fonn as the sun sets and 

often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not 

present, inversions can also be identified by the movement of smoke from a ground source or an aircraft 

smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates, indicateS good 

vertical air mixing. 

SENSITIVE AREAS: 

The pesticide should only be applied when the wind is blowing away from adjacent sensitive areas (e.g. 

residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops). 

COMMERCIAL GREENHOUSES AND NURSERIES 

For general weed control in commercial greenhouses (beneath benches), field grown and container stock, 

and other similar areas, Solera Diquat Landscape and Aquatic Herbicide may be applied preplant or 

postplant preemergence in field grown omamental nursery plantings or postemergence as a directed spray. 

Solera Diquat Landscape and Aquatic Herbicide may also be applied preemergence in ornamental seed 

crops (except in the state of Cali fomi a). Avoid contact with desirable foliage as injury may occur. Do not 

use on food or feed crops. 

Spot spray: 1-2 qts. Solera Diquat Landscape and Aquatic Herbicide plus the labeled rate ofa 75% or 

greater nonionic surfactant per 100 gals. of water, or 0.75 oz. (22 mls.) Solera Diquat Landscape and

Solera Diquat Landscape and Aquatic Herbicide provides fast control ofbroadleafand grassy weeds in 

industrial, recreational, golf course, conunercial, residential, and public areas. 

Solera Diquat Landscape and Aquatic Herbicide is a nonselective herbicide that rapidly kills undesirable 

above ground weed growth in 24-36 hours. Avoid application of Soler a Diquat Landscape and Aquatic 

Herbicide to desirable plants. 

Solera Diquat Landscape and Aquatic Herbicide is a contact/desiccant herbicide; it is essential to obtain 

complete coverage ofthe target weeds to get good control. Improper application technique and/or 

application to stressed weeds may result in unacceptable weed control. For best results, apply to actively 

growing, young weeds. 

Difficult weeds (such as perennial or deeply-rooted weeds) can often be controlled by tank mixing Solera 

Diquat Landscape and Aquatic Herbicide with other systemic-type herbicides. Refer to other product labels 

for specific application directions. 

For residual weed control, tank mix Solera Diquat Landscape and Aquatic Herbicide with a preemergent 

herbicide labeled for the intended use site. When mixing Solera Diquat Landscape and Aquatic Herbicide 

with another herbicide, it is recommended to mix just a small amount first to determine if the mixture is 

physically compatible before proceeding with larger volumes. 

Source Dynamics, LLC has not tested all pOSSible tank mixtures with other herbicides for compatibility, 

efficacy or other adverse effects. Before mixing with other herbicides Source Dynamics, LLC recommends 

you first consult your state experimental station, state university or extension agent. 

Grounds maintenance weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a 

spot or broadcast spray to control weeds in public, commercial and residential landscapes, including 

landscape beds, lawns, golf courses and roadsides. Solera Diquat Landscape and Aquatic Herbicide can 

also be used for weed control around the edges and nonflooded portions of ponds, lakes and ditches. 

Trim and Edge weed control: Solera Diquat Landscape and Aquatic Herbicide can be used to eliminate 

undesired grass and broadleafplant growth in a narrow band along driveways, walkways, patios, cart paths, 

fence lines, and around trees, ornamental gardens, buildings, other structures, and beneath nonconunercial 

greenhouse benches. Vegetation control with Solera Diquat Landscape and AquatiC Herbicide is limited to 

the spray application width. Do not exceed the labeled rate of Sol era Diquat Landscape and Aquatic 

Herbicide as excessive rates may result in staining of concrete-based materials. 

Solera Diquat Landscape and Aquatic Herbicide, since it does not translocate systemically, can be used as

AQUA TIC USE DlRECflONS 

New York - Not for Sale or Use in New York State without Supplemental Special Local 

Needs Labeling. 

Necessary approval and/or permits must be obtained prior to application if required. Consult the 

responsible State Agencies (i.e., Fish and Game Agencies, State Water Conservation authorities, or 

Department of Natural Resources). 

Treannent of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of 

oxygen ntaycause fish suffocation. Therefore, treat only 1/3 to 112 of the water body area. at one time and 

wait 14 days between treatments. 

For best n::sults on submersed weeds, Sclera Diquat Landscape and Aquatic Herbicide should be applied 10 

actively growing (photosynthesizing) weeds when water temperatures have reached or exceeded 

approximately SO°F, typically during the Spring or early Summer.

Spot Treatment: Apply Solera Diquat Landscape and Aquatic Herbicide at 2 quruts per 100 gallons spray 

carrier (0.5% solution) with an approved aquatic wetting ageut at 0.25-1.0% v/v (I quart to I gallon per 100 

gallons water). For cattail control, Solera Diquat Landscape and Aquatic Herbicide should be applied prior 

to flowering at the maximum application rate (8 quarts of Sol era Diquat Landscape and Aquatic 

Herbicide/ 100 gallons spray carrier) plus the wetting agent. Repeat treatments may be necessary for 

complete control. 

Spray to completely wet target weeds but not to runoff. Densely packed weeds or mats may require 

additional applications due to incomplete spray coverage. Re-treat as needed. For best results, retreat weed 

escapes within 2 weeks of the initial treatment. 

Broadcast Treatment: Apply Solera Diquat Landscape and Aquatic Herbicide at the rate of 0.5-2.0 

gallons per surface acre in sufficient carrier along with 16-32 oz'/A ofan approved wetting agent. Re-treat 

as necessary for densely populated weed areas. Good coverage is necessary for control of the target weeds.

For severe weed or algae infestations, the use of an approved algaecide either as a pretreatment to the 

Solera Diquat Landscape and Aquatic Herbicide application or in a tank mix, may result in enhanced weed 

control. 

To control submersed weeds, apply SoleraDiquat Landscape and Aquatic Herbicide in water at 0.5-2.0 

gallons per surface acre (per 4 foot water depth). For severe weed infestations, use the 2.0 gallon per 

surface acre rate. For best results, re-treat as necessary on 14-21 day intervals. The table below shows how 

many gallons of Solera Diquat Landscape and Aquatic Herbicide to apply per surface acre based on water

Note. . For water depths of2 feet or less mc1udmg shorelmes, do not exceed 1 gallon per surface acre . 

Subsurface Applications: Where the submersed weed growth, especially Hydrilla, has reached the water 

surface, apply either-in a water carrier or an invert emulsion through boom trailing hoses carrying nozzle 

tips to apply the dilute spray below the water surface to insure adequate coverage. 

Bottom Placement: Where submersed weeds such as Hydrilla, Bladderwort, or Coontail have reached the 

water surface and/or where the water is slowly moving through the weed growth, the use ofan invert 

emulsion carrier injecting diluted Solera Diquat Landscape and Aquatic Herbicide near the bottom with 

weighted hoses may improve control. The addition of a copper based algaecide may improve control. If 

algae are present along with the submersed weeds, a pretreannent with a copper based algaecide may 

improve overall control. 

Surface Application for Submerged Aquatic Weeds: Apply the recommended rate ofSoleraDiquat 

Landscape and Aquatic Herbicide as a spray in sufficient carrier to fully cover the target area Applications 

should be made to ensure complete coverage of the weed areas. In mixed weed populations, use the high 

rate of application as indicated by weeds present. For dense submersed weeds or water over 2 feet deep, a 

surface spray is not recommended (Solera Diquat Landscape and Aquatic Herbicide should be applied 

subsurface in these situations.)

INTRODUCTION 

Source Dynamics has submitted product chemistry data for to support the reg"lStration of the end use 

product Solera Diquat 2L Desiccant. TRB has been asked to evaluate the product chemistry data (Group 

A & B) under MRID 476340011hrough 03 and 47633901-02. To support the registration of the proposed 

product, the registrant has requested to bridge the product chemistry data submitted earlier in support of 

other product of Diquat Dibromide 37.3%" with File Symbol No. 83529-RE, RG and 79676-TL that have 

been reviewed previously by TRB (DP343449, 09/19/07, DP344335, 10/17/07 and DP348739, 217108) 

and were found acceptable. The registrant provided data compensation forms with an offer to pay for the 

data that was used from other registrants to support product chemistry data requirements. 

The registrant also submitted the proposed product label and the proposed basic and alternate CSFs 

(dated 11-29-08 and replacement CSFs for the basic and alternate formulations dated 4/10/09). The 

registrant also clalmed that the proposed product is substantially similar' to the registered product EPA 

Reg. No. 100-1061. TRB was asked to review the submitted data to determine its acceptability and 

whether the "similarity claim" to Reglone desiccant, EPA Reg. No. 100-1061 can be substantiated. 

SUMMARY OF FINDINGS 

1. The end use product contains 37.3% Diquate dibrom ide as the nom inal concentration for the active 

ingredient with the product label claim of 37.3%. 

2. The CSF for basic formulation da1ed 11/29/2008 was rejected and replaced by revised CSFs for1he 

basic and alternate form ulations da1ed April 10, 2009. The revised CSFs were filled out correctly & 

completely. The nominal concentration of the active ingredient concurs with the label claim. All the inert 

ingredients in the formulation are approved by the Agency for the proposed label uses. The registrant has 

proposed standard certified limits as set forth in the table of 40 CFR158.175 (b)(2) for the all the inert 

ingredients. 

3. The subm'rtted product chemistry data corresponding to test guidelines 830.1550 (product identity and 

composition) satisfy the data requirement.

used to produce the product) including 830.1650 (description of formulation process) and 830.1670 

(discussion of the formation of impurities) satisfy the data requirements. 

5. The petitioner submitted information for guideline 830.1800 (enforcement analytical method) that must 

be validated and certified under GLP to satisfy the data requirements. 

6. The Storage Stability (830.6317) and the Corrosion Characteristics (830.6320) data can be accepted 

from other registrants with the offer to pay only when identical packaging is used for these products. 

Information about the packaging was not provided to support the use of the cited data. 

CONCLUSIONS 

1. TRB has evaluated the product chemistry data and the proposed revised CSFs for the basic and 

altemate formulations (dated 04/9/09) and has found them to be acceptable. 

2. The Storage Stability (830.6317) and the Corrosion Charac1eristics (830.6320) data requirements was 

not satisfied. The registrant cannot use others data with an offer to pay unless the packaging are 

identical 

3. This product is similar to the "me too" cited product from product chemistry perspective. The physical 

properties and chemical composition of the two products are vey much comparable. The product is also 

identical to products 83529~12. 83529-13 and 79676-75. 

4. The registrant offered to pay for data that was used for the registrations of identical products under 

registration numbers 83529-13 (RG). 83529-12 (RE) and 79676·75(TL). 

5. The enforcement analytical method was referenced from CIPAC page 73-9 and described in MRID 

47634003.

BACKGROUND: Source Dynamics LLC has applied for registration of Solera Diquat 

Landscape and Aquatic Herbicide, EPA File Symbol 82542-RU. The Registrant is using the 

selective method of data support to satisfy the acute toxicity data requirements. A data matrix 

citing acute oral, acute dermal, acute inhalation, primary eye irritation and primary skin irritation 

studies with MRIDs 470990-12 to -16 is provided. A search of the OPP electronic databases 

shows that these acute toxicity studies were submitted to support the registration of a product 

with 41.1 % active ingredient, Sharda Diquat Concentrate, EPA Reg. No. 82633-2. The studies 

were reviewed and classified as acceptable in a prior TRB memo (Hashim; D377720; 

20/0CT/2007). 

RECOMMENDATIONS: TRB has compared the CSFs of 82542-RU, the proposed product, 

and 82633-2, the cited product, and has detennined that the fonnulations are substantially 

similar. The cited acute toxicity data may be used to support the registration of the proposed 

product. 

The acute toxicity profile for the proposed product, Solera Diquat Landscape and Aquatic 

Herbicide, EPA File Symbol 82542-RU, is as follows: 

acute oral toxicity II cited MRlD 47099012 

acute dennal toxicity III cited MRlD 47099013 

acute inhalation toxicity III cited MRID 47099014 

primary eye irritation III cited MRlD 47099015 

primary skin irritation III cited MRlD 47099016 

dennal sensitization negative cited EPA Reg. No. 82633-2 

The proposed basic CSF dated November 29, 2008 should be approved by the TRB Product 

Chemistry Team. 

LABELING: Based on the toxicity profile above, the following are the precautionary and first 

aid statements for this product as obtained from the Label Review System:

Footnotes 

A This consideration does not apply to PRlA applications that include a request to 

approve an inert in the fee category. For these PRIA actions, information needs to be 

submitted to enable the Agency to review the inert approval request and will be a subject 

of the 21 day content screen. For other types of actions and for fragrances, the answer is 

only for the Agency's information and current policies, processes, and procedures should 

be consulted. This worksheet will be updated in the future to be consistent with current 

policies. 

Ifbrand, trade, or proprietary names are being used for some inert ingredients listed on 

the CSF, alternate names or additional information on the nature of the ingredient(s) 

should be provided to allow the Agency to determine whether the inert has been 

approved. 

B. A policy on documentation of offers to pay is still being developed, however, for a 

me·too or fast track (similarlidentical) new product, R300 or AS30, an application 

without the necessary authorizations of offers to pay will be placed into either R301 or 

AS3l. The Agency recommends that authorizations of offers to pay be submitted with 

other PRIA applications to avoid delays in the Agency's decision. 

C. Refer to the list of data requirements. Biopesticide applicants were advised to contact 

the Agency and discuss study waivers prior to submitting their application to the Agency. 

Documentation of such discussions should be submitted with the study waiver.

SPECIFIC USE DIRECTIONS 

Solera Diquat Landscape and Aquatic Herbicide is a nonvolatile herbicidal chemical for use as a general 

herbicide to control weeds in commercial greenhouses and nurseries; ornamental seed crops (flowers, 

bulbs, etc. - except in the state of California); landscape, industrial, recreational, commercial, residential, 

and public areas; turf renovation (all turf areas except commercial sod fanus); donnant established 

turfgrass (bennudagrass, zoysiagrass - nonfood or feed crop); and aquatic areas. Absorption and herbicidal 

action is usually quite rapid with effects visible in a few days. Solera Diquat Landscape and Aquatic 

Herbicide controls weeds by intetfering with photosynthesis within green plant tissue. Weed plants should 

be succulent and actively growing for best results. Rinse all spray equipment thoroughly with water after 

use. A void spray drift to crops, ornamentals, and other desirable plants during application, as injury may 

result. Application to muddy water may result in reduced controL Minimize creating muddy water during 

application. Use of dirty or muddy water for Solera Diquat Landscape and Aquatic Herbicide dilution may 

result in reduced herbicidal activity. A void applying under conditions of high wind, water flow, or wave

detenuine the potential for spray drift. The applicator and the grower are responsible for considering all 

there factors hen making decisions. 

The following drift management requirements must be followed to avoid off-target drift movement from 

aerial applications to agricultural field crops. These requirements do not apply to forestry applications, 

public health uses or to applications suing dry fonnulations: 

• The distance of the outennost nozzles on the boom must not exceed:y., the length of the wingspan 

or rotor. 

• Nozzles must always point backward parallel with the air stream and never be pointed downward 

more than 45 degrees. 

Where states have more stringent regulations, they must be observed. 

DROPLET SIZE: 

The most effective ay to reduce drift potential is to apply large droplets. The best drift management 

strategy is to apply the largest droplets that provide sufficient coverage and control. Applying larger 

droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under 

unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions 

sections of the label). 

CONTROLLING DROPLET SIZE: 

Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher 

rated flows produce larger droplets. 

Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle types, 

lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles 

instead of increasing pressure. 

Number of Nozzles - Use the minimum number of nozzles that provide unifonn coverage. 

Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the air stream produces ",,; ~ , larger droplets than other orientations and is the recommended practice. Significant deflection from 

horizontal will reduce the droplet size and increase drift potential. ; , ) , , , : " 

Nozzle Type - Use a nozzle type that is designed for the intended application. With most .Iloz:rle;'types, , • 

narrower spay angles produce larger droplets. Consider using low-drift nozzles. Solid strPyfl,ll) ,n,opes 

oriented straight back produce the largest droplets and the lowest drift. : '"' 

BOOM LENGTH: ';'. 

For some use patterns, reducing the effective boom length to less than % of the wingspan or triter lengtl' : , 

may further reduce drift without reducing swath width. . , :, '

Applications should not be made at a height greater than 10 feed above the top of the largest plants illliess a 

greater height is required for aircraft safety. Making applications at the lowest height that is safe reduces 

exposure of droplets to evaporation and wind. 

SWATH ADJUSTMENT, 

When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up 

and downside edges for the field, the applicator must co.mpensate for this displacement by adjusting the 

path of the aircraft upwind. Swath adjustment distance should increase with increasing drift potential 

(higher wind, smaller droplets, etc.). 

WIND, 

Drift potential is lowest between wind speeds of2~10 mph. However, many factors, including droplet size 

and equipment type, determine drift potential at any given speed. Application should be avoided below 2 

mph due to variable wind direction and high inversion potential. NOTE: Local terrain can influence "Wind 

patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. 

TEMPERATURE AND HUMIDITY: 

When making applications in low relative humidity, setup equipment to produce larger droplets to 

compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. 

TEMPERATURE INVERSIONS: 

Applications should not occur during a temperature inversion because drift potential is high. Temperature 

inversions restrict vertical air mixing, which causes small~suspended droplets to remain in a concentrated 

cloud. This cloud can move in unpredictable directions due to the light variable winds common during 

inversions. Temperature inversions are characterized by increasing temperatures with altitude and are 

common on nights with limited cloud cover and light to no wind. They begin to funn as the sun sets and 

often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not 

present, inversions can also be identified by the movement of smoke from a ground source or an aircraft 

smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind 

conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates, indicates good 

vertical air mixing. 

SENSITIVE AREAS: 

The pesticide should only be applied when the wind is blowing away from adjacent sensitive areas (e.g. 

residential areas, bodies of water , known habitat for threatened or endangered species, non~target crops).

Solera Diquat Landscape and Aquatic Herbicide provides fast control of broad leaf and grassy weeds in 

industrial, recreational, golf course, commercial, residential, and public areas. 

Solera Diquat Landscape and Aquatic Herbicide is a nonselective herbicide that rapidly kills undesirable 

above grOlmd weed growth in 24-36 hours. Avoid application of Sol era Diquat Landscape and Aquatic 

Herbicide to desirable plants. 

Solera Diquat Landscape and Aquatic Herbicide is a contact/desiccant herbicide; it is essential to obtain 

complete covemge ofthe target weeds to get good control. Improper application technique and/or 

application to stressed weeds may result in lUlacceptable weed control. For best results, apply to actively 

growing, young weeds. 

Difficult weeds (such as perennial or deeply-rooted weeds) can often be controlled by tank mixing Solera 

Diquat Landscape and Aquatic Herbicide with other systemic-type herbicides .. Refer to other product labels 

for specific application directions. 

For residual weed control, tank mix Solera Diquat Landscape and Aquatic Herbicide with a preemergent 

herbicide labeled for the intended use site. When mixing Solera Diquat Landscape and Aquatic Herbicide 

with another herbicide, it is recommended to mix just a small amount first to determine ifthe mixture is 

physically compatible before proceeding with larger volumes. 

Source Dynamics, LLC has not tested all possible tank mixtures with other herbicides for compatibility, 

efficacy or other adverse effects. Before mixing with other herbicides Source DynamiCS, LLC reconunends 

you first consult your state experimental station, state lUliversity or extension agent. 

Grounds maintenance weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a 

spot or broadcast spray to control weeds in pUblic, commercial and residential landscapes, including 

landscape beds, lawns, golf courses and roadsides. Solera Diquat Landscape and Aquatic Herbicide can 

also be used for weed control around the edges and nonflooded portions of ponds, lakes and ditches. 

Trim and Edge weed control: Solera Diquat Landscape and Aquatic Herbicide can be used to eliminate 

undesired grass and broadleafplant growth in a narrow band along driveways, walkways, patios, cart paths, 

fence lines, and arolUld trees, ornamental gardens, buildings, other structures, and beneath noncommercial 

greenhouse benches. Vegetation control with Solera Diquat Landscape and Aquatic Herbicide is limited to 

the spray application width. Do not exceed the labeled rate of Sol era Diquat Landscape and Aquatic 

Herbicide as excessive rates may result in staining of concrete-based materials. 

Solera Diquat Landscape and Aquatic Herbicide, since it does not translocate systemically, can be used as 

an edging or pruning tool when precisely applied to select areas of grass or to undesirable growth on 

desirable ornamental bedding plants, grolUld covers, etc. 

Industrial weed control: Solera Diquat Landscape and Aquatic Herbicide can be used as a spot or 

broadcast spray either alone or in combination with other herbicides as a fast burndown or control weeds in 

rights-of-ways, railroad beds/yards, highways, roads, dividers and medians, parking lots, pipelines, 

pumping stations, public utility lines, transformer stations and substations, electric utilities, storage yards, 

and other non-crop areas. 

Spot spray: Apply either 1-2 qts. of Solera Diquat Landscape and Aquatic Herbicide p Ius the labeled rate 

ofa 75% or greater nomonic surfactant per 100 gals. water, or 0.75 oz. (22 mls.) Solera Diquat Landscape 

and Aquatic Herbicide plus the labeled rate ofa 75% 01' greater nonionic surfactant per I gal. of water. 

Broadcast: 1-2 pts. Solera Diquat Landscape and Aquatic Herbicide per acre in sufficient water to insure 

good spray coverage. Add the labeled rate of 75% or greater nonionic surfactant per 100 gals. spray 

mixture. Greater water volumes are necessary if the target plants are tall and/or dense. It is recommended 

that 60 gals. or greater water volume be used to obtain good coverage of dense weeds.

AQUATIC USE DffiECTIONS 

New York - Not for Sale or Use in New York State without Supplemental Special Local 

Needs Labeling. 

Necessary approval and/or permits must be obtained prior to application if required. Consult the 

responsible State Agencies (i.e., Fish and Game Agencies, State Water Conservation authorities, or 

Department of Natural Resources). 

Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds. This loss of 

oxygen may cause fish suffocation. Therefore, treat only 113 to 112 of the water body area at one time and 

wait 14 days between treatments. 

For best results on submersed weeds, Solera Diquat Landscape and Aquatic Herbicide should be applied to 

actively growing (photosynthesizing) weeds when water temperatures have reached or exceeded 

approximately 50ap, typically during the Spring or early Summer. 

For application only to still water (i.e. ponds, lakes, and drainage ditches) where there is minimal or no 

outflow to public waters.
