RESISTANCE MANAGEMENT RECOMMENDATIONS 

V-10142 Ag Herbicide is a Group 2 herbicide. Any weed population may contain or 

develop plants naturally resistant to V-10142 Ag and other Group 2 herbicides. Weed 

species with acquired resistance to Group 2 herbicides may eventually dominate the 

weed population if Group 2 herbicides are used repeatedly in the same field or in 

successive years as the primary method of control for targeted species. This may result 

in partial or total loss of control of those species by V-10142 Ag or other Group 2 

herbicides. 

To delay herbicide resistance consider: 

• Avoiding the consecutive use of V-10142 Ag or other target site of action Group 2 

herbicides that might have a similar target site of action, on the same weed 

species. 

• Using tank mixtures or premixes with herbicides from different target site of action 

Groups as long as the involved products are all registered for the same use, have 

different sites of action and are both effective at the tank mix or prepack rate on the 

weed(s) of concern. 

• Basing herbicide selection on an Integrated Pest Management (IPM) program that 

includes scouting, record keeping, and consideration of cultivation practices, water 

management, weed free crop seed, crop rotation, and other chemical or cultural 

control practices. 

• Monitoring treated weed population for resistance development and reporting 

suspected resistance. 

• Contacting your local extension specialist, certified crop advisors and/or 

manufacturer for herbicide resistance management and/or integrated weed 

management recommendations for specific crops and resistant weed biotypes. 

For further information or to report suspected resistance, you may contact Valent U.S.A. 

Corporation at the following toll-free number: 800-682-5368.

GENERAL INFORMATION 

V-10142 Ag is a selective herbicide which provides contact and residual control of 

susceptible weeds in labeled crops. V-10142 Ag inhibits the enzyme acetolactate synthase 

(ALS), which plants require to produce three key amino acids. Nutsedge and other 

susceptible weeds usually stop growing within 7 to 14 days after treatment, and turn yellow 

or brown within 21 days after treatment. Plant death typically occurs by 21 to 28 days after 

treatment. 

V-10142 Ag is absorbed by plant foliage and roots. Plant uptake and performance of 

V-10142 Ag is influenced by environmental conditions, cultural practices and spray 

coverage. 

For postemergence application, applying V-10142 Ag to actively growing weeds optimizes 

control and/or suppression of susceptible weeds. Factors such as weed species present, 

size of weeds at application, environmental conditions and other factors which affect plant 

metabolism may affect the length of residual activity and the degree of control provided by 

V-10142 Ag. 

Restrictions and Limitations

• Do not apply more than 6.4 oz/A (0.3 lb ai/A) of V-10142 Ag during a single application. 

• Do not apply more than 6.4 oz/A (0.3 lb ai/A) of V-10142 Ag during a single calendar 

year. 

• After application of V-10142 Ag, temporary yellowing or stunting of the crop may occur. 

• Do not apply V-10142 Ag when weather conditions favor drift from treated areas. 

• For aerial application, do not apply V-10142 Ag Herbicide within 1/4 mile of emerged 

cotton or non-STS soybeans. 

• For ground application, do not apply V-10142 Ag Herbicide within 100 feet of emerged 

non-target crops. 

• Do not apply to rice fields if fields are used for the aquaculture of edible fish and/or 

crustaceans. 

• Do not apply V-10142 Ag during low-level inversion conditions, including fog. 

• Do not apply V-10142 Ag to stressed crops or weeds. Stress conditions include, but are 

not limited to, soil moisture above field capacity, drought, temperatures below or above 

those known to be conducive for healthy growth, low fertility, carryover from a previous 

pesticide application or conditions/factors that decrease plant metabolism. 

• When applying V-10142 Ag by air (to rice only), observe “Spray Drift Management” 

instructions and precautions listed under “Aerial Application”. 

• Do not apply V-10142 Ag using airblast spray equipment. 

• Follow V-10142 Ag label directions in “Sprayer Cleanout” section. 

• Water drained from V-10142 Ag treated fields must not be used to irrigate other crops. 

• Do not apply V-10142 Ag to second crop (stubble/ratoon) rice. 

• Do not apply V-10142 Ag in tank mix combination or sequential application programs 

with other soil residual acetolactate synthase (ALS) inhibiting herbicides on tomatoes or 

peppers. 
8 

• Do not apply V-10142 Ag to a crop that has received or will receive a soil applied 

organophosphate insecticide. 

• Do not apply V-10142 Ag within 21 days before, or 7 days after, a foliar 

organophosphate insecticide application. 

• After application of V-10142 Ag follow all normal agricultural cultural practices, including 

cultivation, and ensure that adequate soil moisture is maintained either by rainfall or 

irrigation. 

• Weed biotypes that exhibit resistance or tolerance to herbicides that inhibit the ALS 

enzyme may also exhibit resistance or tolerance to V-10142 Ag. 

Environmental Conditions and Biological Performance 

V-10142 Ag should be used as an integral part of a weed control program in conjunction 

with a resistance management strategy (see “Resistance Management” statement in this 

label). The mode of action is the inhibition of the ALS enzyme. V-10142 Ag will, in most 

cases, prevent the emergence of susceptible weeds if application is made to a clean wellprepared seedbed. In some instances, susceptible weeds may germinate and emerge after 

application, but then growth ceases. The weed becomes chlorotic and either dies within 7 

to 21 days or remains green but significantly stunted and noncompetitive. For optimum 

results from an application made prior to the emergence of susceptible weeds, rainfall or 

sprinkler irrigation is needed to move V-10142 Ag into the soil. Applications to emerged 

susceptible weeds should be made when weeds are actively growing, have adequate soil 

moisture, are 1 to 3 inches in height and are not stressed due to 

environmental/biological/soil conditions [such as drought, extreme (high or low) 

temperatures, inadequate soil fertility, diseases or insects]. Susceptible weeds larger than 1 

to 3 inches in height may not be adequately controlled. If cultivation is necessary to control 

unsusceptible weeds or for susceptible weeds that were larger than the recommended size 

at application, delay cultivation for at least 7 days after the application. Cultivation made 

either 1 to 7 days prior to a postemergence application, or sooner than 7 days after an 

application, may result in unacceptable or partial weed control. 

Rainfastness 

For postemergence applications V-10142 Ag is rainfast 6 hours after application. 

Soil Characteristics 

Soil pH, temperature and moisture affect the degradation of V-10142 Ag. Soil pH above 7, 

low temperatures and lack of moisture (less than 18 inches of rainfall, or irrigation, in the 

first six months after application) will decrease the degradation rate of V-10142 Ag. In 

cropping systems that employ drip irrigation the rotational interval may need to be 

extended. These conditions also affect soil microbial populations, and increase the 

persistence of V-10142 Ag in the soil. Persistence of V-10142 Ag in the soil increases the 

potential for rotational crop injury and yield reduction. 

Adjuvants 

When an adjuvant is to be used with this product, Valent recommends the use of a 

Chemical Producers and Distributors Association certified adjuvant. For applications of 

V-10142 Ag that require a surfactant or other adjuvant, refer to the Valent Bulletin, 

“Approved Surfactants for Use with V-10142 Ag”. 
9 

Mixing and Spraying Equipment Preparation and Cleanup 

Precaution: Do not use chlorine bleach with ammonia. Remove all traces of liquid fertilizer 

containing any form of ammonia or ammonium before adding any chlorine source such as 

chlorine bleach. 

Prior to using V-10142 Ag thoroughly drain, clean and rinse all mixing and spraying 

equipment that will come in contact with V-10142 Ag. Follow the cleanup procedures 

recommended by the manufacturer of the previously sprayed product. Failure to remove all 

deposits of previously sprayed products may result in collection of V-10142 Ag residues 

and inhibit cleanup of mixing and spraying equipment after V-10142 Ag use. Failure to 

remove all deposits of previously sprayed products may also result in reduced efficacy of 

V-10142 Ag and/or crop injury. 

Mixing Instructions 

1. Fill the tank one-half full of clean water. 

2. Begin agitation. 

3. Buffer spray water if pH is below 7. If foaming is anticipated, add defoamer prior to the 

addition of the surfactant. Do not use products that reduce the pH of the spray solution 

as they may reduce weed control. 

4. Add the required amount of V-10142 Ag. 

5. Add the surfactant if the application is to be made after weed emergence. 

6. Add tank mix partner (if any) in the following order: 

a. Water soluble packets (preferably added before the surfactant). 

b. Water dispersible granules/wettable powder 

c. Soluble powders/UAN 

d. Suspension concentrate 

e. Emulsifiable concentrate 

7. Fill the remainder of the tank. 

8. Mix only the amount of spray solution that can be applied the day of mixing. 

 V-10142 Ag must be applied within 12 hours of mixing. 

Application Equipment 

Application equipment should be clean and functioning properly. Proper sprayer calibration 

is required. Nozzles should be spaced to provide even, complete coverage and calibration 

should frequently be checked for accuracy. Select nozzles that deliver the recommended 

gallonage. Use the pressure range recommended by the manufacturer for the selected 

nozzle. 

SPRAY DRIFT MANAGEMENT 

• Aerial application refers to rice only. 

Do not allow spray from ground or aerial equipment to drift onto adjacent land or 

crops. The interaction of many equipment and weather related factors determines the 

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

factors involved in minimizing drift potential. 
10 

When drift may be a problem, do everything possible to reduce spray drift. The 

following aerial drift reduction advisory information must be followed to avoid off target drift 

movement from aerial applications to agricultural field crops. 

1. Do not spray if wind speed is greater than 8 mph or less than 2 mph. If sensitive 

crops or plants are downwind, extreme caution must be used under all conditions. 

2. The distance between the outermost nozzles on the boom must not exceed 3/4 the 

length of the wingspan or rotor. 

3. Nozzles must always point backward parallel with the air stream and never be 

pointed downwards more than 45 degrees. Where states have more stringent 

regulations, they must be observed. 

4. Do not apply under conditions involving possible drift to food, forage or other 

plantings that might be damaged or the crops thereof rendered unfit for sale, use or 

consumption. 

5. When making tank mixture applications follow the most restrictive label directions, 

including application buffer zones, of each product in the mixture. 

6. Nozzles should be at a minimum of 10 inches below the trailing edge of the wing on 

a fixed wing aircraft to prevent spray particles from being released into turbulent air. 

Importance of Droplet Size 

The best drift management strategy is to apply the largest droplets that provide sufficient 

coverage and control. Use nozzle types and nozzle arrangements that will provide 

maximum coverage and minimize the potential for off target movement of spray particles. 

Droplet size for both ground and air applications must be in the “medium” size category as 

defined in the August 1999 ASAE S572 publication entitled, “Spray Nozzle Classification by 

Drop Spectra”. Refer to that publication for additional information. Regardless of droplet 

size, if applications are made improperly or under unfavorable environmental conditions off 

target movement will occur. (see Wind, Temperature and Humidity, and Temperature 

Inversion sections in this label). 

Controlling Droplet Size 

Volume: Use high flow rate nozzles that produce medium droplets to apply the 

highest practical spray volume. 

Pressure: Use the lower spray pressures recommended for the nozzle and do not 

exceed the manufacturer’s recommended pressure. Higher pressure reduces droplet 

size and does not improve canopy penetration. 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 uniform 

coverage. 

Nozzle orientation: Orienting nozzles so that the spray is released backwards 

parallel to the air-stream will produce larger droplets than other orientations. 

Significant deflection from the horizontal will reduce droplet size and increase drift 

potential. 
11 

Nozzle type: Use a nozzle type that is designed for the intended application. Do not 

use air inducting or flood type nozzles. 

Boom length: For some use patterns, reducing the effective boom length to less 

than 3/4 of the wingspan or rotor length may further reduce drift without reducing 

swath width. 

Application: Applications should not be made at a height greater than 10 feet 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 cross wind, the swath will be displaced downwind. 

Therefore, on the up and downwind edges of 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 drops, etc.). 

Wind 

Variable wind speeds with changing directions may pose the largest potential for drift 

damage if crops other than rice are adjacent to the field to be sprayed. Drift potential is 

lowest between wind speeds of 2 to 8 mph. However, many factors, including droplet size 

and equipment type determine drift potential at any given speed. Application must be 

avoided if wind speed is 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 drift. 

Temperature and Humidity 

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

droplets to compensate for evaporation, but they still should remain within the medium 

droplet size category. Droplet evaporation is most severe when conditions are both hot and 

dry. 

Temperature Inversions 

Do not spray at times when spray particles may be entrained into a temperature inversion 

layer. If inversion conditions are suspected, consult with local weather services before 

making an application. Applications must not occur during 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 connected cloud (under low wind conditions) indicates an inversion, while 

smoke that moves upwards and rapidly dissipates indicates good vertical air mixing. 
12 

Sensitive Areas 

The pesticide must only be applied when the potential for drift to adjacent sensitive areas 

(e.g., residential areas, bodies of water, known habitat for threatened or endangered 

species, non-target crops) is minimal (e.g., when wind is blowing away from the sensitive 

areas). 

Sprayer Cleanout 

Residual amounts of herbicide in/on mixing or spraying equipment may have an adverse 

effect on subsequently sprayed crops. Thoroughly drain, clean and rinse all mixing and 

spraying equipment (including tanks, booms, hoses, strainers, screens and nozzles) 

immediately after use. Use the following procedure: 

1. Remove all physical residue. 

2. Thoroughly drain and rinse tanks, booms and hoses with clean water. 

3. Fill the tank one-half full of clean water and use a spraying/mixing tank cleaner that 

does not contain chlorine. Let agitate/re-circulate according to the directions of the 

cleaner manufacturer. Thoroughly flush the boom and hoses before draining. 

4. Rinse all hoses, tanks, nozzles, strainers and booms with clean water to remove the 

tank cleaner. Follow the directions provided by the tank cleaner manufacturer. 

5. Fill the tank half full of clean water and add one (1) gallon of 3% active household 

ammonia for every 100 gallons of water the tank will hold. Fill the remainder of the 

tank with clean water and allow the solution to agitate/recirculate for 15 minutes. 

Thoroughly flush the ammonia cleaning solution through the boom, nozzles, screens 

and strainers before draining the tank. 

6. Remove the strainers, nozzles and screens and clean separately in a solution of one 

part 3% active household ammonia to 100 parts water. 

7. Replace the strainer(s), nozzles and screens. 

8. Repeat step 5. 

9. Thoroughly rinse the tank with clean water and flush the water through the boom, 

nozzles and hoses in order to remove the traces of ammonia. 

10. Dispose of the rinsate on site or at an approved waste disposal facility. 
13 

ROTATIONAL RESTRICTIONS 

The following rotational intervals are recommended for crop safety. Crop injury may result if 

the specified intervals are not followed. The rotational interval should be extended 6 to 8 

months if either drought conditions and/or extended periods of cool conditions occur after 

application. These conditions and/or failure to use conventional tillage and cultivation 

cultural practices increases the persistence of V-10142 Ag in the soil and therefore 

increases the potential for rotational crop injury and yield reduction. In cropping systems 

that employ drip irrigation, the rotational interval may need to be extended.

DIRECTIONS FOR USE IN PEPPERS (BELL AND NON BELL) 

Specific Use Instructions 

• Movement of soil may influence residual activity and/or crop response. 

• Use a higher rate if there is a field history of nutsedge or if weed pressure is normally 

heavy. 

• A rainfall event or overhead irrigation supplying 1/2 to 1 inch of water no sooner than 12 

hours, but not more than 5 days after application, is necessary to activate V-10142 Ag 

and carry it into the soil solution. 

• When weeds are emerged at time of application (1 to 3 inches in height), use an 

approved surfactant as specified (see Adjuvant section in this label). 

Restrictions and Limitations

• Do not apply more than 6.4 oz of V-10142 Ag per acre per year. 

• Make only one application per year.

Row Middle, Plastic Mulch or Bare Soil Culture 

A row middle (between the rows) application may be 

made at any time during the cropping season (up to 

21 days before harvest), as long as the peppers are 

well established and at least 10 inches tall. 

• Avoid contact with the pepper crop. When 

application is being made to peppers grown in 

plastic mulch culture, equipment must be adjusted 

to prevent the spray from contacting the plastic.

Directed Spray 

A post-directed application (under the rows) may be 

made at any time during the cropping season (up to 

21 days before harvest), as long as the peppers are 

well established and at least 10 inches tall. 

• Avoid contact with the pepper fruit and direct 

application to the pepper plant. 

• Application must be directed toward the pepper 

stem, no higher than 2 inches from the soil 

surface. 

• Refer to Table 1 for preemergence weeds controlled and weeds suppressed. 

• Refer to Table 2 for postemergence weeds controlled and weeds suppressed.

Ground Application 

For row middle application, determine the area to be sprayed and calculate the amount of 

V-10142 Ag and water needed based on a broadcast total spray volume of 20 to 40 gallons 

of water per acre and a V-10142 Ag rate of 4.27 to 6.4 oz/A (0.2 to 0.3 lb ai/A). For 

example, if the rows are 36 inches and 18 inches between the rows is the area to be 

sprayed at the rate of 6.4 oz/A (0.3 lb ai/A), the V10142 Ag calculation is: 

Band Width in Inches 

Row Width in Inches 

X Rate per Broadcast 

Acre = Amount V-10142 Ag Needed per Acre for Row Middle Application 

Example: 18” x 6.4 oz/A = 3.2 oz/A for row middle application 

36” 

If the broadcast water volume selected is 30 gallons per acre, the calculation is: 

Band Width in Inches 

Row Width in Inches 

X Spray Volume per 

Broadcast Acre = Amount of Water Volume per Acre for Row Middle Application 

Example: 18” x 30 gal = 15 gal water per acre for row middle application 

 36” 

DIRECTIONS FOR USE IN TOMATO 

Specific Use Instructions 

• Movement of soil may influence residual activity and/or crop response. 

• Use a higher rate if there is a field history of nutsedge or if weed pressure is normally 

heavy. 

• A rainfall event or overhead irrigation supplying 1/2 to 1 inch of water no sooner than 

12 hours, but not more than 5 days after application, is necessary to activate V-10142 

Ag and carry it into the soil solution. 

• When weeds are emerged at time of application (1 to 3 inches in height), use an 

approved surfactant as specified (see adjuvant section in this label). 

Restrictions and Limitations 

• Do not apply more than 6.4 oz of V-10142 Ag per acre per year. 

• Make only one application per year. 

• Make application to field grown tomatoes only. 

• Do not apply V-10142 Ag by air on tomatoes.

DIRECTIONS FOR USE IN RICE 

Specific Use Instructions 

• Use the higher rate if there is a field history of nutsedge or if weed pressure is normally 

heavy. 

• A rainfall event supplying 1/2 to 1 inch of water no sooner than 12 hours, but not more 

than 5 days after application is necessary to activate V-10142 Ag and carry it into the 

soil solution. 

• When weeds are emerged at time of application (1 to 3 inches in height), use an 

approved surfactant as specified (see Adjuvant section in this label). 

• At the time of application to dry broadcast seeded or water-seeded rice, the seed and 

roots must be covered with soil and the plant must be living entirely off of the root 

system. 

• When application is made post-flood, the flood water must be lowered so that at least 

70% of the weed surface is above the flood water. Bring the field to normal flood level 3 

to 4 days after application. 

• When application is made to non-flooded fields, flood the fields as soon as the rice will 

tolerate a flood, but not sooner than 24 hours after application. 

Restrictions and Limitations

• Do not apply to second crop (stubble/ratoon) rice. 

• Fields with a history of weed resistance to ALS-inhibiting herbicides may exhibit 

resistance to V-10142 Ag.

• For aerial application, do not apply V-10142 Ag within 1/4 mile of emerged cotton or 

non-STS soybeans. 

• For ground application, do not apply V-10142 Ag within 100 feet of emerged non-target 

crops. 

• Do not apply to rice fields if fields are used for the aquaculture of edible fish and/or 

crustaceans. 

• Do not drain the field for 7 days after application when making a postemergence 

application to a flooded field. 

• Do not apply more than 6.4 oz of V-10142 Ag per acre per year. 

• At the time of application to broadcast dry-seeded or water-seeded rice, the seed and 

roots must be covered with soil and the plant must be living entirely off the root system. 

• For tank mix applications with propanil containing products, read and follow the entire 

label of each product to be used in the tank mix. 

• Do not apply an organophosphate insecticide within 21 days before, or 7 days after, an 

application of V-10142 Ag.

20 

Aerial Application - Rice Only 

Uniformly apply V-10142 Ag by aircraft in no less than 10 gallons of water per acre total 

spray volume. Inadequate coverage will result in unacceptable weed control and/or weed 

regrowth. Any factor, such as reduced spray volume, which adversely affects coverage 

and/or canopy penetration will have a negative effect on the performance of V-10142 Ag. 

Use nozzle arrangements that provide maximum coverage and minimize potential for off 

target movement of spray particles. Droplet size should be in the “medium” size category 

as defined in the August 1999 ASAE S572 publication entitled, “Spray Nozzle Classification 

by Droplet Spectra”. Refer to that publication for additional information. 

Ground Application 

Apply V-10142 Ag in a minimum of 10 gallons of water per acre and ensure thorough, 

uniform coverage.
