I. PRODUCTINFORMA TlON . 

This product is a selective postemergence herbicide for controrring a wide spectrum of annual, biennial, 

and perennial broad leaf weeds and brush in grass forages and selected row crops. 

Mode of Action 

This product contains two active ingredients: dicamba and 2,4-D. This herbicide is readily absorbed by 

plants through shoot and root uptake, translocates throughout the plant's system, and accumulates in 

areas of active growth. This product interferes with the plant's growth hormones (auxins) resulting in 

death of many broadleafweeds. 

Cleaning Spray Equipment 

Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner 

according to the manufacturer's direction and then triple rinsing the equipment before and after applying 

this product. 

II. APPLICATION PROCEDURES 

Apply this product at the rates and growth stages listed in Tables 1 and 2 as forrows unless instructed 

differently by Section VI or VIr. (Food/Feed Crop Specific Information or Non-Food/Feed Use Specific 

3 

6
Information). Applications can be made to actively growing weeds as aerial, broadcast, band, or spot 

spray applications. This product may be applied using water or sprayable fluid fertilizer as a carrier. 

Sprayable fluid fertilizer may be used as the carrier in preplant or pre-emergence uses for all crops listed 

on this label. Postemergence uses with sprayable fluid fertilizer may be made on pasture, hayland, or 

wheat crops only. 

The most effective application rate and timing varies based on the target weed species (refer to Table 1). 

In mixed populations of weeds the correct rate is determined by the weed species requiring the highest 

rate. Delaying application permits weeds to exceed the maximum size stated and will prevent adequate 

control. 

IRRIGATION 

In irrigated areas, it may be necessary to irrigate before treatment to ensure active weed growth. 

SPRAY COVERAGE 

Weeds must be thoroughly covered with spray. Dense leaf canopies shelter smaller weeds and can 

prevent adequate spray coverage. 

SPRAY DRIFT MANAGEMENT 

A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative 

humidity) and method of application (e.g., ground, aerial, airblast, chemigation) can influence pesticide 

drift. The applicator must evaluate all factors and make appropriate adjustments when applying this 

product. 

Importance of Droplet Size 

The most effective way to reduce drift when applying sprays that contain 2,4-0 as the sole active 

ingredient, or when applying sprays that contain 2,4-0 mixed with active ingredients that require a Coarse 

or coarser spray, apply only as a Coarse or coarser spray (ASAE standard 572) or a volume mean 

diameter of 385 microns or greater for spi nning atomizer nozzles. 

When applying sprays that contain 2,4-0 mixed with other active ingredients that require a Medium or 

more fine spray, apply only as a Medium or coarser spray (ASAE standard 572) or a volume mean 

diameter of 300 microns or greater for spi nning atomizer nozzles. 

Wind Speed 

Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors ontarget deposition and there are not sensitive areas (including, but not limited to, residential areas, bodies 

of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind. If applying a 

Medium spray, leave one swath unsprayed at the downwind edge of the treated field. 

Temperature Inversions 

If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature 

inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make 

applications into areas of temperature inversions or stable atmospheric conditions. 

Susceptible Plants 

Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that 

might be damaged or crops thereof rendered unfit for sale, use or consumption. Susceptible crops 

include, but are not limited to, cotton, okra, flowers, grapes (in growing stage), fruit trees (foliage), 

soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or 

tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants. 

Sensitive Crop Precautions 

This product may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit trees, 

4 

7
grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes and other broad leaf 

plants when contacting their roots, stems or foliage. These plants are most sensitive to this product during 

their development or growing stage. 

Do not treat areas where either possible downward movement into the soil or surface washing may cause 

contact of this product herbicide with the roots of desirable plants such as trees and shrubs . 

• Avoid making applications when spray particles may be carried by air currents to areas where sensitive 

crops and plants are growing. Do not spray near sensitive plants if wind is gusty or in excess of 5 mph 

and moving in the direction of nearby sensitive crops or if temperature inversion exists. However, always 

make applications when there is some air movement to determine the direction and distance of possible 

spray drift. Leave adequate buffer zone between area to be treated and sensitive plants. Coarse 

sprays are less likely to drift out of the target area than fine sprays. AgriculturaUy-approved drift-reducing 

additives may be used . 

• Do not use aerial equipment or apply this product when sensitive crops and plants are growing in the 

vicinity of area to be treated. 

Other State and Local Requirements 

Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-0 

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

Equipment 

All aerial and ground application equipment must be properly maintained and calibrated using 

appropriate carriers or surrogates. The boom length must not exceed 75% of the wingspan or 90% of 

the rotor blade diameter. 

Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a 

height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. 

This requirement does not apply to forestry or rights-of-way applications. 

When applications are made with a crosswind, the swath will be displaced downwind. The applicator must 

compensate for this by adjusting the path of the aircraft upwind. 

Do not apply with a nozzle height greater than 4 feet above the crop canopy. 

Application Equipment 

Select nozzles designed to produce minimal amounts of fine spray particles. Make applications at the 

lowest safe height to reduce the exposure of spray droplets to evaporation and wind. The applicator must 

follow the most restrictive use cautions to avoid drift hazards, including those found in this labeling as well 

as applicable state and local regulations and ordinances. 

Do not use aerial equipment if spray particles can be carried by the wind into areas where sensitive crops 

or plants are growing or when temperature inversions exist. 

Sprayer Clean-Out 

To avoid injury to desirable plants, equipment used to apply this product should be thoroughly cleaned 

before re-using to apply any other chemicals. 

1. Rinse and flush application equipment thoroughly at least 3 times with water after use. Dispose of rinse 

water by application to treatment area or in non-cropland area away from water supplies. 

2. During the second rinse, add 1 quart of household ammonia for every 25 gallons of water. Circulate the 

solution through the entire system so that all internal surfaces are contacted (15 to 20 minutes). Let the 

solution stand for several hours, preferably overnight. 

3. Flush the solution out of the spray tank through the boom. 

4. Rinse the system twice with clean water, recirculating and draining each time. 

5 

8
5. Remove nozzles and screens and clean separately. 

Mixing and Loading 

Most cases of groundwater contamination involving phenoxy herbicides, such as 2,4~ 

dichlorophenoxyacetic acid, have been associated with mixing/loading and disposal sites. Caution should 

be exercised when handling 2,4~dichlorophenoxyacetic acid pesticides at such sites to prevent 

contamination of groundwater supplies. Use of closed systems for mixing or transferring this pesticide will 

reduce the probability of spills. Placement of the mixing/loading equipment on an impervious pad to 

contain spills will help prevent groundwater contamination.

3 For improved root kill or weedy species such as mesquite and eastern persimmon, spray 4 pints of this product per acre each 

year for 3 consecutive years. For increased conlrol of weeds such as blackberry and dewberry, this product may be lank mixed 

with Ally® herbicide {0.1 to 0.2 ounces per acre}, if labeled for the use site. 

4 Under dense populations, a second application may be needed the following growing season. 

GROUND APPLICATION (BANDING) 

When applying this product by banding, determine the amount of herbicide and water volume needed 

using the following formula: 

Bandwidth in inches X Broadcast rate = Banding herbicide 

Row width in inches per acre rate per acre 

Bandwidth in inches X Broadcast volume = Banding water 

Row width in inches per acre volume per acre 

GROUND APPLICATION (BROADCAST) 

Water Volume: Use 5M 40 gallons of spray solution per broadcast acre for optimal performance. Use the 

higher spray volume when treating dense or tall vegetation. 

Application Equipment: Select nozzles designed to produce minimal amounts of fine spray particles. 

Spray with nozzles as close to the weeds as is practical for good weed coverage. 

SPOT OR SMALL AREA APPLICATION 

This product may be applied to individual clumps or small areas of undesirable vegetation using handgun 

or similar types of application equipment. Apply diluted sprays to allow complete wetting (up to runoff) of 

foliage and stems. For knapsack or other small capacity sprayers, prepare a solution of this product in 

8 

11
water according to Table 3 (assuming that the spot treatment rate equates to 60 gallons per acre on the 

broadcast basis.) Adding a surfactant (0.5% by volume) can help improve control. For example, 5 gallons 

(40 pints or 640 fluid ounces) of herbicide solution would require 0.2 pints (3.2 fluid ounces) of surfactant. 

Do not make spot treatments in addition to broadcast or band treatments.

III. ADDITIVES 

To improve burndown of emerged weeds, surfactants and/or low use rate of liquid fertilizers (28-0-0, 32-

0-0), or crop oil concentrate may be used with this product or tank mixes with this product applied after 

the weeds have emerged. Crop oil concentrate is for non-food/feed crop uses only. Do not apply tank 

mixes that include Ammonium Sulfate or Crop Oil Concentrate to any food/feed crop use listed on this 

label. For food/feed crop uses, do not use liquid fertilizers that contain Ammonium Sulfate (AMS) as a 

source of nitrogen as tolerances in commodities derived from the crop may contain residues that exceed 

established tolerances. Consult your local Ritter representative for recommendations for your area. For 

additional information, see Compatibility Test for Mix Components. 

OIL CONCENTRATE 

A crop oil concentrate must contain either a petroleum or vegetable oil base and must meet all of the 

following criteria: 

• be non phytotoxic, contain only EPA-exempt ingredients, 

• provide good mixing quality in the jar test, and 

• be successful in local experience. 

The exact composition of suitable products will vary; however, vegetable and petroleum oil concentrates 

should contain emulsifiers to provide good mixing quality. Highly refined vegetable oils have proven more 

satisfactory than unrefined vegetable oils. For additional information, see Compatibility Test for Mix 

Components. 

Adjuvants containing crop oil concentrates may be used for preplant. pre-emergence and between 

cropping applications. Do not use crop oil concentrate for postemergence applications in food/feed crops 

(i. e., sorghum, grass (hay or silage), pastures, rangeland, sugarcane and wheat). 

Nitrogen Source 

Sprayable liquid fertilizers: Use one quart of sprayable liquid fertilizers (28-0-0, 32-0-0) per acre. Do not 

use brass or aluminum nozzles when spraying fertilizers. 

Nonionic Surfactant 

The standard label recommendation is 2-4 pints of an 80% active non ionic spray surfactant per 100 

gallons of water. For certain weeds, use a higher spray surfactant rate.

See section VI. Crop-Specific Information for more details, Read and follow the applicable Restrictions 

and Limitations and Directions For Use on all products involved in tank mixing. The most restrictive 

labeling applies to tank mixes. 

Physical incompatibility, reduced weed control, or crop injury may result from mixing this product with 

other pesticides (fungicides, herbicides, insecticides, or miticides), additives, or fertilizers. Ritter Chemical, 

LLC does not recommend using tank mixes other than those listed on Ritter Chemical, LLC labeling. 

Local agricultural authorities may be a source of information when using other than Ritter Chemical, LLC 

recommended tank mixes. 

COMPATIBILITY TEST FOR MIX COMPONENTS 

Before mixing components, always perform a compatibility jar test. 

For 20 gallons per acre spray volume, use 3.3 cups (800 ml) of water. For other spray volumes, adjust 

accordingly. Only use water from the intended source at the source temperature. 

10 

13
Add components in the sequence indicated in the Mixing Order using 2 teaspoons for each pound or 1 

teaspoon for each pint of recommended label rate per acre. 

Always cap the jar and invert 10 cycles between component additions. 

When the components have all been added to the jar, let the solution stand for 15 minutes, Evaluate the 

solution for uniformity and stability. The spray solution should not have free oil on the surface, nor fine 

particles that preCipitate to the bottom, nor thick (clabbered) texture. If the spray solution is not 

compatible, repeat the compatibility test with the addition of a suitable compatibility agent If the solution 

is then compatible, use the compatibility agent as directed on its label. If the solution is still incompatible, 

do not mix the ingredients in the same tank. 

MIXING ORDER 

If an inductor is used, rinse it thoroughly after each component has been added. Maintain constant 

agitation during application. 

1)Water*. Begin by agitating a thoroughly clean sprayer tank half full of clean water. 

2)Agitation. Maintain constant agitation throughout mixing and application. 

3)Products in PVA bags. Place any product contained in water-soluble PYA bags into the mixing tank. 

Wait until all water-soluble PYA bags have fully dissolved and the product is evenly mixed in the spray 

tank before continuing. 

4) Water-dispersible products (such as dry flowables, wettable powders, suspension concentrates, or 

suspo-emulsions). 

5)Water-soluble products. (such as Duplex) 

6) Emulsifiable concentrates (such as oil concentrate when applicable). 

7)Water-soluble additives (such as liquid fertilizers (28-0-0, 32-0-0) when applicable). 

8) Remaining quantity of water. 

* If sprayable fluid fertilizer is used as the carrier, this product must be diluted with a minimum of 5 parts 

water to 1 part this product Then add 0.25 to .05% volume/volume of a non ionic surfactant to the dilution 

before adding it to the sprayable fluid fertilizer to reduce the concern for compatibility problems with this 

mix. Always perform the Compatibility Test before mixing into the spray tank. Also, when using a 

sprayable fluid fertilizer as the carrier, any product contained in PYA bags must first be completely 

dissolved in water before the contents can be added to the fertilizer mix.

VI. FOOD/FEED CROP-SPECIFIC INFORMATION 

PASTURES, RANGELAND AND GRASS (HAY, SILAGE) 

This product is recommended for use for pasture (including pasture grown for hay), rangeland and grass 

grown for hay or silage. Refer to Tables 1 and 2 for rate selection based on targeted weed or brush 

species. Some weed species will require tank mixes for adequate control. 

Rates above 4 pints of this product per acre are for spot treatments only. Uses described in this section 

also pertain to small grains (such as barley, corn, forage sorghum, oats, rye, sudangrass, or wheat) 

grown for pasture, hay, and silage only. Newly seeded areas, including small grains grown for pasture or 

hay, may be injured if rates of this product greater than 2 pints per acre are applied. 

In newly established hybrid Bermudagrass, Pangolagrass, and stargrasses (Cynodon spp.), use 2 to 4 

pints of this product per acre to control or suppress weeds after planting vegetative propogules (stolens) 

of hybrid bermudagrasses. In addition to the weeds listed in Tables 1 and 2, this rate of this product will 

control or suppress annual sedges, broad leaf signalgrass, crabgrass, and goosegrass. Best results will 

be obtained if this product is applied at the germinating stage of weeds. Under favorable conditions, this 

is usually 7 to 10 days after planting these grasses. Reduced control can be expected if weeds are 

allowed to reach 1" in height before application or if germination of weeds occurs 10 days after 

application. 

Do not use on bentgrass, susceptible grass pastures (such as carpetgrass, buffalograss, or St. Augustine 

grass), lespedeza, wild winter peas, vetch, clover, and alfalfa pastures as injury will occur. 

When perennial weeds are reaching maturity, mowing and allowing some regrowth will enhance control. 

Difficult to control weeds and brush may require repeat applications. 

For pasture renovations, wait 3 weeks per quart (2 pints) of this product used per acre before 

interseeding or injury may occur. If grasses are grown for seed or for seed-down purposes, do not apply 

after grass reaches the joint stage.

FARMSTEAD AND FENCEROW TREATMENT APPLICATION INSTRUCTIONS 

This product may be applied using water or oil and water emulsions in spot application to control 

18 

21
undesirable vegetation using handgun or similar types of application eqUipment. In addition to weed 

species listed in Tables 1 and 2, these treatments may be used to control or suppress woody plant 

species listed in Table 6. 

To prepare oil and water emUlsions, mix in the order and proportions indicated below. 

The solution should remain milky colored without an oily layer on top when under agitation. If an olly layer 

forms, increase the amount of emulsifier or change to a more effective emulsifier. 

Do not exceed 40 gallons of spray solution per treated acre per application. FOrty gallons of spray 

solution contains 1.0 pound acid equivalent of dicamba and 2.87 pounds acid equivalent of 2,4-0. Spray 

plants to wet. Do not allow this spray mix to contact desirable vegetation. 

To control brush, briars, and weeds along fencerows surrounding pasture and ranch lands, and fallow 

fields, use a tank mix of 2.5% of Duplex, 87.5% water, 10% diesel oil, and sufficient emulsifier (to mix the 

diesel and emUlsifier). The diesel oil in this tank mix will damage or kill desirable grasses and should not 

be used in pastures or where damage to desirable species cannot be tolerated. 

1) Water: Begin by agitating a thoroughly clean sprayer tank with the desired quantity of clean water. 

Maintain constant agitation during complete mixing procedure. 

2) Emulsifier: Add 0.5% volume to volume. 

3) Duplex: Add 2.5 gallons per 100 gallons of total intended solution. 

4) Diesel Oil: Add 10 gallons per 100 gallons of total intended solution. 

Maintain constant agitation during application. Under good agitation, the spray solution should be milky 

white with no oil layer on top. If an oil layer forms, increase the amount of emulsifier or change to a more

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. forms, 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 

34
site [link to http://www.epa.gov/opprdOOllinerts/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 (lIAB) at inertsbranch@epa.gov and resolve the issue. Copies of the 

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

new inerts except PIP inerts are reviewed by lIAB. The flAB 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/oppbppdllbiopesticides/contactsbppd.htm]. 

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

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

information [link to http://www.epa.gov/opprdOOI/inerts(tips.pdf] must also be included 

to enable the Agency to detennine 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 W1approved inert is identified on a CSF, the Agency will contact the 

applicant with the following options: 

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

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

removing the unapproved inert from the eSF 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 

35
3. Withdraw the application (the Agency retains 25% of the full fee for the fee 

category estimated); or 

Ifnone 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 of the category identified. 

Conventional New Product Applications 

\\Then 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 (R31l, 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 

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 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 infonnation 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 time frame for both actions. 

5 

36
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 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 applications 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.
