APPLICATION SITE CONDITIONDIRECTIONS 

Soil temperature: maximum of 90°F at application depth 

Soil preparation: 

 Ensure the soil is well prepared and generally free at the surface of large clods. Large clods 

can prevent efficient soil sealing and reduce effectiveness of the product. 

 Cultivate the soil to a minimum depth of 5-8” and/or equal to the desired treatment depth. 

 Thoroughly incorporate plant residues into the soil to allow decomposition prior to treatment. 

Leave little or no plant residue present on the soil surface. Undecomposed plant material 

can harbor pests that will not be controlled and can interfere with the soil seal after 

application. Let crop residue that is present lie flat to permit the soil to be sealed effectively. 

 Where applicable, fracture compacted soil layers (plow pans) within the desired treatment 

zone before or during application of IRF135. 

 Deviation from the above soil preparation conditions can result in less than 

satisfactory results. 

Soil moisture: 

 It is critical to maintain adequate soil moisture before, during and 48 hours post-treatment. 

Plan soil treatment for seasons, crop rotations, or irrigation schedules which leave adequate 

moisture in the soil. 

 The soil must be moist (typically with enough moisture to allow weed seeds to become 

imbibed) from 1.5 inches below the soil surface to at least the minimum desired depth of the 

target treatment zone. The amount of moisture needed (typically greater than 50% Available 

Water Content at 9 inches) in this zone will vary according to soil type. The surface soil 

generally dries very rapidly and is not considered in this determination. 

Weather Conditions: 

 Prior to soil treatment the weather forecast for the day of application and the 48-hour period 

following the soil treatment must be checked to determine if unfavorable weather conditions 

exist or are predicted and whether soil treatment should begin. 

 Apply IRF135 in the presence of wind speeds of at least 2 mph at the start of the 

applications or projected to reach at least 5 mph during the application. 
IRF135; EPA Reg. No. (pending as File Symbol 89285-E) 

MASTER LABEL – version (5) dated July 29, 2012 

Page 6 of 15 

 

 Check weather forecasts 48 hours prior to application to ensure proper conditions are 

present at the time of application. Weather conditions and or advisories can be downloaded 

online at http://www.nws.noaa.gov. 

Buffer Zones: Do not apply IRF135 within 25’ of any occupied structure, such as a school, 

daycare, hospital, retirement home, business or residence. 

Pre-Planting After Application of IRF135 

Effects of Rain: 

 If significant rainfall occurs within 24 hours after IRF135 application (enough to saturate 

soil that has been treated with IRF135), a reduction in pest control can occur. 

Restricted Entry Period following Application: 

 Do not enter the treated area until 48 hours after the application is completed. 

 If entry is required within 48 hours after application only those persons wearing Personal 

Protective Equipment (see Agricultural Use Requirements box) and only for reasons of 

repairing tarp are allowed in the treated area. 

Recontamination Prevention: 

 IRF135 will control pests that are present in the soil treatment zone at the time of soil 

treatment. It will not control pests that are introduced into the soil after soil treatment 

period has ended. To avoid re-infestation of treated soil, DO NOT use irrigation water, 

transplants, seed pieces, or equipment that could carry soil-borne pests from infested 

land. Avoid contamination from moving infested soil onto treated beds through 

cultivation, movement of soil from outside the treated zone, dumping contaminated soil 

in treated fields and soil contamination from equipment or crop remains. Clean 

equipment carefully before entering treated fields. 

Testing of Treated Soils Prior to Planting: 

 Allow IRF135 to dissipate completely before planting the crop. 

 When determining the appropriate time interval before planting, consideration of factors 

that impact IRF135 dissipation include rate of application, depth of injection, soil 

temperature, soil preparation and type, soil moisture and use of various plastic films and 

or water sealing. 

 Use of a lettuce seed and or tomato/pepper transplant test can be used to determine if 

sufficient time has elapsed between soil treatment and planting as described below.

Lettuce Seed Test 

 After a minimum of 7 days after application proceed with the following Seed Jar test. 

 Use a trowel to dig into the treated soil to a depth at or just beneath the depth of IRF135 

injection and remove 2 to 5 samples with enough soil to fill a quart sized jar half-way, 

mix lightly, apply moisture enough to germinate seeds, sprinkle seeds evenly over the 

soil surface and seal immediately with a lid for air tight conditions. 

 Sample the field in several areas, especially those areas that are not representative of 

the general field conditions and or having higher moisture content, different soil texture 

or areas where rate delivery is different. 

 Prepare another similar sample of untreated soil for comparison. 
IRF135; EPA Reg. No. (pending as File Symbol 89285-E) 

MASTER LABEL – version (5) dated July 29, 2012 

Page 7 of 15 

 

 Keep the jars out of direct sunlight and at a temperature of 65o to 85oF. (Direct sunlight 

can overheat and kill the seedlings). Lettuce seed will not germinate in the dark so place 

in diffuse sunlight. 

 After 1 to 3 days, check each jar for seed germination. 

 If seeds in the treated jar germinate and grow similar to the untreated soil sample then 

the treated area is safe for planting. 

Tomato/Pepper Transplant Test 

 After a minimum of 7 days after application proceed with the following transplant test.

 Transplant 5 to 10 healthy, actively growing tomato or pepper seedlings into treated 

beds at normal planting depth and several locations within the treated area. If available 

repeat in an area of field not treated with IRF135 for comparison. If a wetter, heavier 

area of the treated field is available place the transplants there.

 Inspect the transplants in 3 days for plant injury including wilt, chlorosis, or leaf and root 

tip burn. Ensure that proper soil moisture conditions exist for transplants to remain free 

from water stress. If plants in the treated area are asymptomatic and or are similar in 

growth and appearance to plants in the non-treated area it is safe to plant.

IRF135 DRIP INJECTION APPLICATION USE DIRECTIONS: 

Drip Injection Use Precautions: 

 The following applies to drip (trickle) irrigation systems. 

 Crop injury and a reduction in efficacy can result from non-uniform distribution of IRF135 

in irrigation water used to treat soil. 

 For questions related to equipment calibration, consult your local State Extension 

Service specialist, equipment manufacturer or dealer. 

Soil preparation: 

 Ensure compacted soil layers (plow pans) within the desired treatment zone are tilled 

and/or fractured if it is considered normal practice before application of IRF135 to ensure 

adequate soil drainage. Note that conditions where soil layers (plowpans) exist and are 

not tilled can result in reduced pest control, differences in planting interval or plant 

growth as a result of compacted or shallow soil conditions. 

 The application site must be in seedbed condition. Ensure beds are listed, shaped and 

ready for planting. 

 Ensure initial soil moisture is at ~50% of field capacity at 2 to 3 inches and down to 9 

inches depth at the time of IRF135 application. Soil texture and amount of water to be 

applied will impact the desired initial % field capacity necessary for drip injection. 

IRF135 Dosage: 

 Determining IRF135 dosage is based on consideration of the intended crop to be 

planted, treated area conditions, preparation, application method, target pest, and soil 

type. 

 Use drip emitters with spacing of 6 to 12 inches with shallow subsurface placement to 

ensure thorough wetting of the soil area being treated by IRF135 drip injection. 

 IRF135 must be metered at a target concentration between - 1000 – 3000 ppm into the 

water supply line and passed through a mixing device such as a centrifugal pump with 

by-pass agitation or static mixer to assure proper agitation and mixing to a target 

concentration (ppm) for even distribution before distribution into the drip irrigation 
IRF135; EPA Reg. No. (pending as File Symbol 89285-E) 

MASTER LABEL – version (5) dated July 29, 2012 

Page 8 of 15 

 

system. The concentration of IRF135 should not exceed – 3000 ppm at any time during 

the injection period within the drip line. 

 The volume of irrigation water to deliver to the treated area is dependent upon the soil 

type, % soil moisture or the % of field capacity at the start of the application and the 

target moisture level following application and equipment rising. 

 Determine the irrigation water flow and adjust the flow rate of IRF135 to meet the target 

ppm in irrigation water. Insert a static mixer or similar device immediately after the 

IRF135 injection point to insure adequate mixing with the irrigation water. 

General Chemigation Application Information: 

1. Apply this product only through drip (trickle) irrigation systems. Do not apply this product 

through any other type of irrigation system. 

2. Crop injury or lack of effectiveness can result from non-uniform distribution of treated 

water. 

3. If you have questions about calibration, contact State Extension Service specialists, 

equipment manufacturers or other experts. 

4. Do not connect an irrigation system (including greenhouse systems) used for pesticide 

application to a public water system unless the pesticide label-prescribed safety devices 

for public water systems are in place. 

5. A person knowledgeable of the chemigation system and responsible for its operation or 

under the supervision of the responsible person, shall shut the system down and make 

necessary adjustments should the need arise. 

Chemigation Systems Connected to Public Water Systems: 

1. Public water system means a system for the provision to the public of piped water for 

human consumption if such system has at least 15 service connections or regularly 

serves an average of at least 25 individuals daily at least 60 days out of the year. 

2. Chemigation systems connected to public water systems must contain a functional, 

reduced-pressure zone, back flow preventer (RPZ) or the functional equivalent in the 

water supply line upstream from the point of pesticide introduction. As an option to the 

RPZ, the water from the public water system should be discharged into a reservoir tank 

prior to pesticide introduction. There shall be a complete physical break (air gap) 

between the flow outlet end of the fill pipe and the top or overflow rim of the reservoir 

tank of at least twice the inside diameter of the fill pipe. 

For Drip (Trickle) Chemigation Systems: 

1. The irrigation system (main line, headers, drip tape) must be thoroughly inspected for 

leaks before the application starts. The leak detection process requires that the 

irrigations system be at full operating pressure. The time required at full operating 

pressure will vary according to the system design and layout, soil type and target ppm 

concentration. Signs of leaks may include puddling along major pipes and at the top or 

ends of rows and/or on the bed surface or movement or shifting of beds due to bed 

collapse in over saturated conditions. Any leaks discovered must be repaired prior to 

application of IRF135. For leaks discovered during application of IRF135, immediately 

stop injection, wear all appropriate PPE and repair the line insuring that the problem is 

corrected before commencing with the drip applied injection. 

2. The system must contain a functional check valve (back flow prevention device), 

vacuum relief valve, and low pressure drain appropriately located on the irrigation 

pipeline to prevent water source contamination from back flow. 

3. The pesticide injection pipeline must contain a functional, automatic, quick-closing check 
IRF135; EPA Reg. No. (pending as File Symbol 89285-E) 

MASTER LABEL – version (5) dated July 29, 2012 

Page 9 of 15 

 

valve to prevent the flow of fluid back toward the injection pump. 

4. With use of injection pumps (e.g. Diaphragm or Centrifugal type pumps) the pesticide 

injection pipeline must also contain a functional, normally closed, solenoid-operated 

valve located on the intake side of the injection pump and connected to the system 

interlock to prevent fluid from being withdrawn from the supply tank when the irrigation 

system is either automatically or manually shut down. 

5. The system must contain functional interlocking controls to automatically shut off the 

pesticide injection pump when the water pump motor stops or in cases where there is no 

water pump, when the water pressure decreases to the point where pesticide distribution 

is adversely affected. 

6. The irrigation line or water pump must include a functional pressure switch which will 

stop the water pump motor when the water pressure decreases to the point where 

pesticide distribution is adversely affected. 

7. To inject IRF135, use a metering device (such as a positive pressure system, positive 

displacement injection pump, diaphragm pump, or a Venturi system) effectively designed 

and constructed of materials that are compatible with pesticides and capable of being 

fitted with a system interlock. 

8. Use of an inert gas such as nitrogen or dry compressed air is acceptable for use in a 

positive pressure system. 

Injection System Flush After IRF135 Application: 

 After IRF135 injection, continue drip irrigation with clean water to flush remaining IRF135 

completely out of the system. Apply 3 times the volume of water equivalent to the 

capacity of the drip injection system from the point of injection to the ends of the drip 

tape to ensure IRF135 is completely voided from the injection lines and drip tape. 

 Do not allow any IRF135 to remain in the system after application. 

 If common lines are used for both the IRF135 application and to apply the water seal (if 

applied), the lines must be adequately flushed before starting the water seal and/or 

normal irrigation practices. 

Soil Sealing or Tarp Use: 

 When tarps are used with drip injection application, they must be in place prior to 

injection of IRF135. 

 Tarp edges must be buried along the row furrow and at the ends of each row. 

Untarped Drip Applications: 

 The drip tape must be buried a minimum of 5 inches below the soil/air interface. 

Planting Interval for Raised Bed Drip Applications: 

• After application, leave the soil undisturbed for at least 10 days after the application is 

complete. Planting of the target crop is allowed at a minimum of 10 days following the 

completion of the application. 

• Extremely cold, wet, or cold and wet soils can decrease dissipation of IRF135 and can 

require a longer soil exposure and/or aeration period. 

• For tarped applications, where tarp perforation or hole punching occurs allow 2 to 24 

hours aeration prior to planting to assist in IRF135 dissipation. 

• Use of a Jar Seedling and/or Transplant test for crop safety can be performed prior to 

planting the target crop. See pages XX-XX of this label for instructions.

Requirements for Pre-Plant Greenhouse Soil Treatment 

 Applications methods for use in greenhouse soil treatment may be applied as drip 

injection or tractor mounted shank where applicable according to the methods described 

for open field with exceptions listed below: 

o All applications must be tarped or double water sealed (delivered via overhead 

sprinkler) 

o During the application, keep doors, vents and windows to the outside open and 

keep fans or other mechanical ventilation systems running within the application 

area. 

o Areas by which gases could enter adjacent enclosed areas must be sealed prior 

to application and remain closed for up to 48hours post application. 

IRF135 TRACTOR MOUNTED SHANK RAISED BED AND BROADCAST/FLAT 

APPLICATION USE DIRECTIONS:

Soil moisture: 

 For tractor mounted shank applied treatments of IRF135 do not apply to dry soils. Target 

a soil moisture reading of ~50% or greater Available Water Content to a depth of 8 to 9 

inches present for at least 24 to 48 hours prior to and until the start of the application. 

Soil temperature at application: 

 Maximum of 90°F at application depth. 

Application Methods and Equipment: 

 Apply IRF135 using chisels spaced no more than 12 inches apart and no more than 3 

outlets evenly spaced per chisel (rear and forward facing type shank). The top most 

outlet must be no less than – 5 inches from the final air soil interface. 

 For shank applications the use of tarps or a water cap does not eliminate the need to 

remove chisel traces. Use of a press board, ring roller or other device to effectively close 

chisel traces must be performed. 

Application Depth: 

 The point of injection must be a minimum of -5 inches from the final soil/air interface. 

The point of deep injection must be at a minimum of 18 inches from the final soil/air 

interface. Use deeper placement when fumigating soil to be planted to deep-rooted 

plants, such as perennial fruit and nut crops, or to control deeply distributed pests.

Prevention of End Row Spillage: 

 Do not apply or allow IRF135 to spill onto the soil surface. Each injection line either 

needs a check valve located as close as possible to the soil injection point to avoid 

dripping or spillage. If a check valve system is not in place purge and drain the injection 

line prior to lifting the injection shanks from the ground. 

 Only lift the injection shanks from the ground when the shut-off valve has been closed, 

and the IRF135 injection line has been depressurized to passively drain remaining 

IRF135 or when the system has been actively purged (e.g. via air compressor). 

Injection Rig Calibration, Set-up, Repair, and Maintenance: 

IRF135 application equipment must be calibrated and all control systems working properly. 

Proper calibration is critical to ensure IRF135 application rate and soil placement. Refer to the 

equipment manufacturer’s instructions to properly calibrate the injection equipment. The 

equipment dealer, local Cooperative Extension Service, crop advisor or IRF135 dealer can 

provide assistance.

Planting Interval for Raised Bed Shank and Broadcast/Flat Application 

 After application, leave the soil undisturbed for at least 5 days after application prior to 

tarp cutting or perforation/hole punching. 

 For tarped applications, complete cutting of the tarp for removal or perforation/hole 

punching 2 to 24 hours prior to tarp removal or planting to assist in IRF135 dissipation. 

 Tarp cutters and removers shall wear long-sleeved shirt, long pants and gloves when 

there is no waiting or aeration period between tarp cutting and removing the tarp 

following application and prior to planting. 

 Soil can be planted with the target crop at a minimum of 10 days following application. 

 Cold, wet, or cold and wet soils can decrease dissipation of IRF135 and can require a 

longer soil exposure and or aeration period. 

 Soil applied under untarped shanked applications must remain undisturbed for a 

minimum of 10 days following completion of the application before tillage and or planting 

of the target crop. 

 Use of a Jar Seedling and/or Transplant test for crop safety can be performed prior to 

planting the target crop. See pages XX-XX of this label for instructions.
