clean clothing.

Remove PPE immediately after handling this product. Wash the outside of gloves before 

removing. As soon as possible, wash thoroughly and change into clean clothing.

ENVIRONMENTAL HAZARDS:

This product is toxic to non-target plants and aquatic invertebrates. Do not apply directly to water, to 

areas where surface water is present or to intertidal areas below the mean high water mark. Drift or 

runoff may be hazardous to non-target plants and aquatic organisms in neighboring areas. Do not 

apply where runoff is likely to occur. Do not apply when weather conditions favor drift from treated 

areas. Do not contaminate water when disposing of equipment washwaters.

This pesticide is toxic to plants and should be used strictly in accordance with the drift and run-off 

precautions on this label in order to minimize off-site exposures.

Under some conditions this product may have a potential to run-off to surface water or adjacent land. 

Where possible, use methods which reduce soil erosion, such as no till, limited till and contour 

plowing; these methods also reduce pesticide run-off. Use of vegetation filter strips along rivers, 

creeks, streams, wetlands or on the downhill side of fields where run-off could occur will minimize 

water run-off and is recommended.

RESISTANCE MANAGEMENT RECOMMENDATIONS

V-10233 Herbicide is a premix of Group 14 and Group 15 herbicides. Any weed population may 

contain or develop plants naturally resistant to V-10233 Herbicide and other Group 14 and/or Group 

15 herbicides. Weed species with acquired resistance to Group 14 and/or Group 15 herbicides may 

eventually dominate the weed population if Group 14 plus Group 15 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-10233 Herbicide or other Group 14 

and/or Group 15 herbicides.

To delay herbicide resistance consider:

• Avoiding the consecutive use of V-10233 Herbicide or other target site of action Group 14 

and/or Group 15 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 use on a comprehensive Integrated Pest Management (IPM) program.

• Monitoring treated weed populations for loss of field efficacy.

• 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 K-I Chemical at the 

following toll-free number: XXXXXXXX.

PRODUCT INFORMATION

V-10233 Herbicide provides residual control of susceptible weeds in minimum and no-tillage field 

corn. It provides additional burndown activity when used as part of a burndown program in minimum 

and no-tillage field corn. V-10233 Herbicide can be applied as part of a fall burndown program for 

residual control of susceptible winter annuals.

Weeds controlled by V-10233 Herbicide are listed in Table 1. Application rates of V-10233 Herbicide 

vary depending on soil type and organic matter; refer to Table 2.

Moisture is necessary to activate V-10233 Herbicide in soil for residual weed control. When adequate 

moisture is not received after a V-10233 Herbicide application, weed residual control may be 

improved by irrigation with at least 1/4 inch of water. If emerged weeds are controlled by cultivation, 

residual weed control will be reduced. 

Burndown program: Apply V-10233 Herbicide as part of a burndown program to actively growing 

weeds. Applying V-10233 Herbicide under conditions that do not promote active weed growth will

reduce herbicide effectiveness. Do not apply V-10233 Herbicide when weeds are under stress due 

to drought, excessive water, extremes in temperature, disease or low humidity. Weeds under stress 

tend to become less susceptible to herbicidal action. V-10233 Herbicide is most effective when 

applied under warm sunny conditions.

Preemergence Application (Conventional Tillage): Crop injury may occur from applications made to 

poorly drained soils and/or applications made under cool, wet conditions. Risk of crop injury can be 

minimized by using on well drained soils, planting field corn at least 1.5 inches deep, using high 

quality seed and completely covering seeds with soil prior to preemergence applications. Treated soil 

that is splashed onto newly emerged crops may result in temporary crop injury.

Rainfastness: V-10233 Herbicide is rainfast one hour after application. Do not apply V-10233 

Herbicide if rain is expected within one hour of application or postemergence efficacy may be 

reduced. 

Soil Characteristics: Application of V-10233 Herbicide to soils with high organic matter and/or high 

clay content may require higher dosages than soils with low organic matter and/or low clay content. 

Application to cloddy seedbeds can result in reduced weed control.

DIRECTIONS FOR USE IN FIELD CORN

(NO TILL AND MINIMUM TILL)

Apply V-10233 Herbicide at 3 to 4.5 oz/A to field corn (no till and minimum till) early pre-plant. Corn 

must be planted between 7 and 30 days after application unless the application is made as part of 

a fall burndown program. Preemergence application of V-10233 Herbicide provide residual control 

of weeds listed in Table1, Weeds Controlled or Suppressed by Residual Activity of V-10233 

Herbicide. Application rates of V-10233 Herbicide vary depending on soil type and organic matter. 

USE PRECAUTIONS TO FIELD CORN 

• Use only on no-till or minimum tillage fields where last years crop residue has not been 

incorporated into the soil.

• Do not irrigate between emergence and 2-leaf corn.

• Do not use on popcorn, sweet corn or corn grown for seed.

Burndown Use Directions – For Preplant Applications in Field Corn

V-10233 Herbicide, applied as part of a burndown program, may be used for residual weed control, 

as well as to assist in postemergence burndown of many weeds where field corn will be planted 

directly into the residue of the previous year. See Directions for Use in Fall and Spring Preplant 

Burndown and Fallow Seedbed Programs in Field Corn for rates and timing of applications. For 

control of emerged weeds, V-10233 Herbicide must be applied with an appropriate burndown tank 

mix partner. To ensure thorough coverage, use a minimum of 15 gallons of spray solution per acre. 

Refer to tank mix partner’s label for recommended application pressure and recommended adjuvant 

systems. 

TANK MIXES

V-10233 Herbicide may be tank mixed with 2,4-D LVE, atrazine, Basis®, Dicamba, Express®,

ghlyphosate, Hornet®, paraquat, Python®, d, Resolve®, simazine, , Weedmaster®, for pre-plant 

burndown applications. Refer to tank mix partner’s label for adjuvant recommendations. Refer to tank 

mix product labels for specific recommendations
17

DIRECTIONS FOR USE IN FALL AND SPRING PREPLANT BURNDOWN PRIOR TO 

PREEMERGENCE TO FIELD CORN

Apply V-10233 Herbicide at 3 to 4.5 oz/A in the fall to provide residual weed control in fields that will 

be planted the following spring with field corn. Weeds controlled or suppressed by residual activity 

are listed in Table 1, Weeds Controlled or Suppressed by Residual Activity of V-10233 Herbicide. 

Application rates of V-10233 Herbicide vary depending on soil type and organic matter. If weeds have

DIRECTIONS FOR USE IN FALLOW LAND

Apply V-10233 Herbicide, at 3 to 4.5 oz/A, in combination with labeled burndown herbicides to 

control emerged weeds and provides residual weed control. Weeds controlled by residual activity are 

listed in Table 1, Weeds Controlled or Suppressed by Residual Activity of V-10233 Herbicide.

DIRECTIONS FOR USE TO MAINTAIN BARE GROUND

ON NON-CROP AREAS OF FARMS, ORCHARDS AND VINEYARDS

Use V-10233 Herbicide to maintain bare ground on non-crop areas of farms, orchards and vineyards, 

for non-selective vegetation control and to maintain bare ground on non-crop areas that must be kept 

weed free. Follow all directions as outlined in “PRODUCT INFORMATION” section of this label.

V-10233 Herbicide offers residual and postemergence control of susceptible broadleaf and grass 

weeds as well as an additional mode of action to assist in the control of ALS (acetolactate synthase) 

resistant weeds. V-10233 Herbicide can be tank mixed with the herbicides listed in Table 5, Tank 

Mix Combinations to Maintain Bare Ground on Non-Crop Areas, for increased residual or 

postemergence control. The length of residual control is dependent on the rate applied as well as on 

rainfall and temperature conditions. Length of residual control will decrease as temperature and 

precipitation increase. V-10233 Herbicide rates of 3 to 4.5 oz/A are required to provide residual 

control of the weeds listed in Table 1, Weeds Controlled or Suppressed by Residual Activity of 

V-10233 Herbicide.
21

USE PRECAUTIONS

• Do not apply to farm alleys or roads where traffic may result in treated dust settling onto crops or 

other desirable vegetation. 

• Do not apply to ditch banks.

PREEMERGENCE APPLICATION

Apply 3 to 4.5 oz/A of V-10233 Herbicide per broadcast acre as a preemergence application. Make 

the preemergence (to weed emergence) applications of V-10233 Herbicide to a weed-free soil 

surface. Preemergence applications of V-10233 Herbicide must be completed prior to weed 

emergence. Moisture is necessary to activate V-10233 Herbicide on soil for residual weed control. 

Dry weather following application of V-10233 Herbicide may reduce effectiveness. However, when 

adequate moisture is received after dry conditions, V-10233 HERBICIDE will control susceptible 

germinating weeds.

POSTEMERGENCE APPLICATION

Apply 3 to 4.5 oz/A of V-10233 Herbicide per broadcast acre plus an adjuvant (0.25% v/v non-ionic 

surfactant or 1 qt/A crop oil concentrate). The addition of an adjuvant enhances V-10233 Herbicide 

activity on emerged weeds. Thorough spray coverage is necessary to maximize the postemergence 

activity of V-10233 Herbicide. Emerged weeds are controlled postemergence with V-10233 

Herbicide, however, translocation of V-10233 Herbicide within a weed is limited, and control is 

affected by spray coverage and by the addition of an adjuvant. The most effective postemergence 

weed control with V-10233 Herbicide occurs when applied in combination with a surfactant to weeds 

less than 2 inches in height. A tank mix partner must not be used in combination with V-10233 

Herbicide for the postemergence control of weeds larger than 2 inches.

IMPORTANT: Completely read and follow the label of any potential tank mix partner with V-10233 

Herbicide. When using tank mixtures, use conditions must be in accordance with the most restrictive 

of the label limitations and precautions on either herbicide label.

APPLICATION INFORMATION

SPRAYER PREPARATION

Before applying V-10233 Herbicide, start with clean, well maintained application equipment. The 

spray tank, as well as all hoses and booms, must be cleaned to ensure no residue from the previous 

spraying operation remains in the sprayer. Some pesticides, including but not limited to, the 

sulfonylurea and phenoxy herbicides, (i.e., Classic® and 2,4-D respectively) are active at very small 

amounts and can cause crop injury when applied to susceptible crops. The spray equipment must 

be cleaned according to the manufacturer's directions for the last product used before the equipment 

is used to apply V-10233 Herbicide. If two or more products were tank mixed prior to V-10233 

Herbicide application, follow the most restrictive cleanup procedure.

MIXING INSTRUCTIONS

1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water.

2. If a drift retardant is to be used, add 10 lbs of spray grade ammonium sulfate per 100 gallons of 

spray solution.

3. To ensure a uniform spray mixture, pre-slurry the required amount of V-10233 Herbicide with 

water prior to addition to the spray tank. Use a minimum of 1 gallon of water per 10 oz of V-10233 

Herbicide.

4. While agitating, slowly add the pre-slurried V-10233 Herbicide to the spray tank. Agitation should 

create a rippling or rolling action on the water surface.

5. If tank mixing V-10233 Herbicide with other labeled herbicides, add water soluble bags first, 

followed by dry formulations, flowables, emulsifiable concentrates and then solutions. Prepare no 

more spray mixture than is required for the immediate spray operation.

6. Add any required adjuvants.

7. Fill spray tank to desired level with water. Agitation should continue until all spray solution 

has been applied.

8. Mix only the amount of spray solution that can be applied the day of mixing. V-10233 HERBICIDE 

should be applied within 6 hours of mixing.

APPLICATION METHOD

V-10233 Herbicide is applied by ground or by air. Application equipment should be clean and in good 
23

repair. Nozzles should be uniformly spaced on boom and frequently checked for accuracy.

1. GROUND APPLICATION

Apply V-10233 Herbicide, and V-10233 Herbicide tank mixes, with ground equipment using 

standard commercial sprayers equipped with flat fan (preplant or preemergence applications 

only) designed to deliver the desired spray pressure and spray volume.

2. AERIAL APPLICATION 

Spray drift away from the site of application may cause damage to non-target vegetation. To 

minimize drift, apply the largest droplet size consistent with uniform coverage and 

satisfactory weed control. To obtain satisfactory application and avoid drift, the following 

directions must be observed:

Do not apply during low-level inversion conditions (including fog), when winds are gusty or 

under other conditions that favor drift. 

Do not spray when wind velocity is less than 2 mph or more than 10 mph.

Do not apply this product by air within 40 ft of non-target plants including non-target crops.

Do not apply this product by air within 100 ft of emerged cotton crops.

Do not apply this product by air within 40 ft of streams, wetlands, marshes, ponds, lakes and 

reservoirs.

CARRIER VOLUME AND SPRAY PRESSURE

1. GROUND APPLICATION: 

Preemergence Application (Conventional Tillage): To ensure uniform coverage, use 10 

to 30 gals. of spray solution per acre for conventional tillage applications. Nozzle selection 

should meet manufacturer's gallonage and pressure recommendations for preemergence 

herbicide application.

Burndown Application (Prior to Crop Emergence): To ensure thorough coverage in 

burndown applications, use 15 to 60 gals. spray solution per acre. Use 20 to 60 gals. per acre 

if dense vegetation or heavy crop residue is present. Nozzle selection should meet 

manufacturer's gallonage and pressure recommendations for postemergence herbicide 

application. Do not use flood jet nozzles

2. AERIAL APPLICATION:

When used as part of a burndown weed control program, apply V-10233 Herbicide in 7 to 10 

gallons.of water per acre. Application at less than 7 gallons per acre may provide inadequate 

control. When used for preemergence weed control, apply V-10233 Herbicide in 5 to 10 

gallons of water per acre. The higher gallonage applications generally afford more consistent 

weed control. 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.

NOZZLE SELECTION AND ORIENTATION

Use nozzles that produce flat or hollow cone spray patterns. Use non-drip type nozzles, such as 

diaphragm type nozzles, to avoid unwanted discharge of spray solution. The nozzles must be 

directed toward the rear of the aircraft, at an angle between 0 and 15° downward. Do not place 

nozzles on the outer 25% of the wings or rotors.

ADJUVANTS AND DRIFT CONTROL ADDITIVES 

Refer to tank mix partner’s label for adjuvant recommendation. Drift control additives may be used. 

When a drift control additive is used, read and carefully observe the cautionary statements and all 

other information appearing on the additive label.
24

SPRAY DRIFT MANAGEMENT

Do not apply under circumstances where possible drift to unprotected persons or to food, forage or 

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

can occur.

Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets 

may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream 

as much as possible and by avoiding excessive spray boom pressure. For ground boom and 

aerial applications, use medium or coarser spray nozzles according to ASAE 572 definition for 

standard nozzles or a volume mean diameter (VMD) of 300 microns or greater for spinning 

atomizer nozzles.

Make aerial or ground applications when the wind velocity favors on-target product deposition. 

Apply only when the wind velocity is less than 2 mph or more than 10 mph. For all non-aerial 

applications, wind speed must be measured adjacent to the application site on the upwind side, 

immediately prior to application.

Do not make aerial or ground applications into areas of temperature inversions. Inversions are 

characterized by stable air and increasing temperatures with increasing distance above the 

ground. Mist or fog may indicate the presence of an inversion in humid areas. Where permissible 

by local regulations, the applicator may detect the presence of an inversion by producing smoke 

and observing a smoke layer near the ground surface.

Low humidity and high temperatures increase the evaporation rate of spray droplets and 

therefore the likelihood of increased spray drift. Avoid spraying during conditions of low humidity 

and/or high temperatures.

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

appropriate carriers.

For ground boom applications, apply with nozzle height no more than 4 ft above the ground or 

crop canopy.

SPRAYER CLEANUP

Spray equipment, including mixing vessels and nurse tanks, must be cleaned each day following 

V-10233 Herbicide application. After V-10233 Herbicide is applied, the following steps must be used 

to clean the spray equipment:

1. Completely drain the spray tank, rinse the sprayer thoroughly, including the inside and outside 

of the tank and all in-line screens.

2. Fill the spray tank with clean water and flush all hoses, booms, screens and nozzles.

3. Top off tank, add 1 gallon of 3% household ammonia (or equivalent) for every 100 gallons of 

water, circulate through sprayer for 5 minutes, and then flush all hoses, booms, screens and 

nozzles for a minimum of 15 minutes. If diaphragms are being used on the spray boom, loosen 

diaphragms before flushing the spray system, allowing cleaning solution to spray through the 

open diaphragm. If spray lines have any end caps, they must be loosened before flushing the 

system, allowing cleaning solution to spray though the loosened caps. To enhance removal of 

V-10233 Herbicide from the spray system, add a tank cleaner such as “Valent Tank Cleaner”, in 

place of ammonia and allow the cleaning solution to remain in the pressurized spray system 

(spray tank, hoses and boom) for 8 hours before flushing the system for a minimum of 15 

minutes.

4. Drain tank completely.

5. Add enough clean water to the spray tank to allow all hoses, booms, screens and nozzles to be 

flushed for 2 minutes.

6. Remove all nozzles and screens and rinse them in clean water.

Thoroughly clean spray equipment, including all tanks, hoses, booms, screens and nozzles, before 

it is used to apply postemergence pesticides. Equipment with V-10233 Herbicide residue remaining 

in the system may result in crop injury to the subsequently treated crop.
25

ADDITIVES

When an adjuvant is to be used with V-10233 Herbicide, Valent USA Corporation recommends the 

use of a Chemical Producers and Distributors Association certified adjuvant. Either a crop oil 

concentrate or methylated seed oil which contains at least 15% emulsifiers and 80% oil or a non-ionic 

surfactant at 0.25% v/v, may be used when applying V-10233 Herbicide as part of a burndown 

program. Some tank mix partners, such as Roundup PowerMAX®, are formulated with sufficient 

adjuvants and do not require the addition of a crop oil concentrate, methylated seed oil or non-ionic 

surfactant when tank mixed with V-10233 Herbicide. The addition of a crop oil concentrate or 

methylated seed oil may increase the burndown activity on certain weeds such as cutleaf 

eveningprimrose and Carolina geranium. Verify mixing compatibility qualities by a jar test.

A spray grade nitrogen source (either ammonium sulfate at 2 to 2.5 lbs/A or a 28 to 32% nitrogen 

solution at 1 to 2 qts/A) may be added to the spray mixture along with either a crop oil concentrate, 

methylated seed oil or non-ionic surfactant to enhance weed control. The addition of a nitrogen 

source does not replace the need for a crop oil concentrate, a methylated seed oil or a non-ionic 

surfactant.

JAR TEST TO DETERMINE COMPATIBILITY OF ADJUVANTS AND V-10233 HERBICIDE

When using V-10233 Herbicide and an adjuvant, such as in stale seed bed or reduced tillage 

situations, a jar test should be performed before mixing commercial quantities of V-10233 Herbicide, 

when using V-10233 Herbicide for the first time, when using new adjuvants or when a new water 

source is being used.

1. Add 1 pt of the water to a quart jar. The water should be from the same source and temperature 

as which will be used in the spray tank mixing operation.

2. Add 1 g of V-10233 Herbicide to the quart jar for every 3 oz of V-10233 Herbicide per acre being 

applied

(2 g if 6 oz/A is the desired V-10233 Herbicide rate), gently mix until product goes into 

suspension. 

3. Add 60 ml (4 Tbsps or 2 fl oz) of the crop oil or methylated seed oil to the quart jar or 

1 ml of non-ionic surfactant if it is being used in place of oil, gently mix.

4. If nitrogen is being used, add 16 ml (1 Tbsp or 0.5 oz) of the 28 to 32% nitrogen source to the 

quart jar. If ammonium sulfate is being used, add 19 g AMS to the quart jar in place of the 28 to 

32% nitrogen.

5. Place cap on jar, invert 10 times, let stand for 15 minutes, evaluate.

6. An ideal tank mix combination will be uniform and free of suspended particles. If any of the 

following conditions are observed the choice of adjuvant should be questioned:

a) Layer of oil or globules on the mixture’s surface.

b) Flocculation: fine particles in suspension or as a layer on the bottom of the jar.

c) Clabbering: Thickening texture (coagulated) like gelatin.

RESISTANCE MANAGEMENT RECOMMENDATIONS

V-10233 Herbicide is a premix of Group 14 and Group 15 herbicides. Any weed population may contain 

or develop plants naturally resistant to V-10233 Herbicide and other Group 14 and/or Group 15 

herbicides. Weed species with acquired resistance to Group 14 and/or Group 15 herbicides may 

eventually dominate the weed population if Group 14 plus Group 15 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-10233 Herbicide or other Group 14 and/or 

Group 15 herbicides.

To delay herbicide resistance consider:

• Avoiding the consecutive use of V-10233 Herbicide or other target site of action Group 14 and/or 

Group 15 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 use on a comprehensive Integrated Pest Management (IPM) program.

• Monitoring treated weed populations for loss of field efficacy.

• 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.

PRODUCT INFORMATION

V-10233 Herbicide is a preemergence and early postemergence herbicide for control of selected grass 

and broadleaf weeds in and around ornamental woody shrubs, deciduous trees and conifers grown 

outdoors in containers or in the field (in ground) and to maintain bare ground non-crop areas. 

Weeds controlled by V-10233 Herbicide are listed in Table 1, Weeds Controlled or Suppressed by 

Residual Activity of V-10233 Herbicide.

Preemergence weed control with V-10233 Herbicide is most effective when applied to clean, weed free 

soil surfaces. The most effective postemergence weed control with V-10233 Herbicide occurs when 

applied in combination with a surfactant to weeds less than 2 inches in height. Follow specific site use 

directions prior to using surfactant as certain over the top applications restrict the use of the surfactants.

PRODUCT USE PRECAUTIONS

Do not apply in enclosed greenhouse structures.

Do not apply when weather conditions favor spray drift from treated areas.

Do not graze treated fields or feed treated forage or hay to livestock.

Do not incorporate into soil after application.

Do not apply this product through any type of irrigation system.

Do not apply to turfgrass. 

APLICATION INFORMATION

SPRAYER PREPARATION

Before applying V-10233 Herbicide, start with clean, well maintained application equipment. The spray 

tank, as well as all hoses and booms, must be cleaned to ensure no residue from the previous spraying 

operation remains in the sprayer. Some pesticides, including but not limited to, the sulfonylurea and 

phenoxy herbicides, are active at very small amounts and can cause crop injury when applied to 

susceptible crops. The spray equipment must be cleaned according to the manufacturer's directions for 

the last product used before the equipment is used to apply V-10233 Herbicide. Follow the most 

restrictive cleanup procedure If two or more products were tank mixed prior to V-10233 Herbicide 

application.

MIXING INSTRUCTIONS

1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water.

2. If a drift retardant is to be used, add 10 lbs of spray grade ammonium sulfate per 100 gallons of 

spray solution.

3. To ensure a uniform spray mixture, pre-slurry the required amount of V-10233 Herbicide with 

water prior to addition to the spray tank. Use a minimum of 1 gallon of water per 10 oz of V-10233 

Herbicide.

4. While agitating, slowly add the pre-slurried V-10233 Herbicide to the spray tank. Agitation should 

create a rippling or rolling action on the water surface.

5. If tank mixing V-10233 Herbicide with other labeled herbicides, add water soluble bags first, 

followed by dry formulations, flowables, emulsifiable concentrates and then solutions. Prepare no 

more spray mixture than is required for the immediate spray operation.

6. Add any required adjuvants.

7. Fill spray tank to desired level with water. Agitation should continue until all spray solution 

has been applied.

8. Mix only the amount of spray solution that can be applied the day of mixing. V-10233 HERBICIDE 
37

should be applied within 6 hours of mixing.

APPLICATION METHOD

V-10233 Herbicide is applied by ground or by air. Application equipment should be clean and in good 

repair. Nozzles should be uniformly spaced on boom and frequently checked for accuracy.

1. GROUND APPLICATION

Apply V-10233 Herbicide, and V-10233 Herbicide tank mixes, with ground equipment using 

standard commercial sprayers equipped with flat fan (preplant or preemergence applications 

only) designed to deliver the desired spray pressure and spray volume.

2. AERIAL APPLICATION 

Spray drift away from the site of application may cause damage to non-target vegetation. To 

minimize drift, apply the largest droplet size consistent with uniform coverage and satisfactory 

weed control. To obtain satisfactory application and avoid drift, the following directions must be 

observed:

Do not apply during low-level inversion conditions (including fog), when winds are gusty or 

under other conditions that favor drift. 

Do not spray when wind velocity is less than 2 mph or more than 10 mph.

Do not apply this product by air within 40 ft of non-target plants including non-target crops.

Do not apply this product by air within 100 ft of emerged cotton crops.

Do not apply this product by air within 40 ft of streams, wetlands, marshes, ponds, lakes and 

reservoirs.

CARRIER VOLUME AND SPRAY PRESSURE

When used as part of a burndown weed control program, apply V-10233 Herbicide in 7 to 10 gallons 

of water per acre. Application at less than 7 gallons per acre may provide inadequate control. When 

used for preemergence weed control, apply V-10233 Herbicide in 5 to 10 gallons of water per acre. 

The higher gallonage applications generally afford more consistent weed control. 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. 

NOZZLE SELECTION AND ORIENTATION

Use nozzles that produce flat or hollow cone spray patterns. Use non-drip type nozzles, such as 

diaphragm type nozzles, to avoid unwanted discharge of spray solution. The nozzles must be 

directed toward the rear of the aircraft, at an angle between 0 and 15° downward. Do not place 

nozzles on the outer 25% of the wings or rotors.

ADJUVANTS AND DRIFT CONTROL ADDITIVES

Refer to tank mix partner’s label for adjuvant recommendation. Drift control additives may be used. 

When a drift control additive is used, read and carefully observe the cautionary statements and all 

other information appearing on the additive label.

SPRAY DRIFT MANAGEMENT

Do not apply under circumstances where possible drift to unprotected persons or to food, forage or other 

plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption can occur.

Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets 

may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream 

as much as possible and by avoiding excessive spray boom pressure. For ground boom and aerial 

applications, use medium or coarser spray nozzles according to ASAE 572 definition for standard 

nozzles or a volume mean diameter (VMD) of 300 microns or greater for spinning atomizer nozzles.

Make aerial or ground applications when the wind velocity favors on-target product deposition. 
38

Apply only when the wind speed is less than or equal to 10 mph. For all non-aerial applications, wind 

speed must be measured adjacent to the application site on the upwind side, immediately prior to 

application.

Do not make aerial or ground applications into areas of temperature inversions. Inversions are 

characterized by stable air and increasing temperatures with increasing distance above the ground. 

Mist or fog may indicate the presence of an inversion in humid areas. Where permissible by local 

regulations, the applicator may detect the presence of an inversion by producing smoke and 

observing a smoke layer near the ground surface.

Low humidity and high temperatures increase the evaporation rate of spray droplets and therefore 

the likelihood of increased spray drift. Avoid spraying during conditions of low humidity and/or high 

temperatures.

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

appropriate carriers.

For ground boom applications, apply with nozzle height no more than 4 ft above the ground or crop 

canopy.

SPRAYER CLEANUP

Spray equipment, including mixing vessels and nurse tanks, must be cleaned each day following 

V-10233 Herbicide application. After V-10233 Herbicide is applied, the following steps must be used to 

clean the spray equipment:

Completely drain the spray tank, rinse the sprayer thoroughly, including the inside and outside of 

the tank and all in-line screens.

Fill the spray tank with clean water and flush all hoses, booms, screens and nozzles.

Top off tank, add 1 gallon of 3% household ammonia (or equivalent) for every 100 gallons of water, 

circulate through sprayer for 5 minutes, and then flush all hoses, booms, screens and nozzles for 

a minimum of 15 minutes. If diaphragms are being used on the spray boom, loosen diaphragms 

before flushing the spray system, allowing cleaning solution to spray through the open diaphragm. 

If spray lines have any end caps, they must be loosened before flushing the system, allowing 

cleaning solution to spray though the loosened caps. To enhance removal of V-10233 Herbicide 

from the spray system, add a tank cleaner such as “Valent Tank Cleaner”, in place of ammonia and 

allow the cleaning solution to remain in the pressurized spray system (spray tank, hoses and boom) 

for 8 hours before flushing the system for a minimum of 15 minutes.

Drain tank completely.

Add enough clean water to the spray tank to allow all hoses, booms, screens and nozzles to be 

flushed for 2 minutes.

Remove all nozzles and screens and rinse them in clean water.

Thoroughly clean the spray equipment, including all tanks, hoses, booms, screens and nozzles, before 

it is used to apply postemergence pesticides. Equipment with V-10233 Herbicide residue remaining in 

the system may result in crop injury to the subsequently treated crop.

ADDITIVES

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

and Distributors Association certified adjuvant. Mix V-10233 Herbicide with a crop oil concentrate that 

contains at least 15% emulsifiers and 80% oil or a non-ionic surfactant containing at least 80% active 

ingredient when applying V-10233 Herbicide as part of a postemergence weed control program. Verify 

the mixing compatibility by a jar test before using. Do not mix V-10233 Herbicide with a surfactant when 

applying over the top of dormant woody ornamentals or conifer trees.

A spray-grade nitrogen source (either ammonium sulfate at 2.0 to 2.5 lb/A or a 28 to 32% nitrogen 
39

solution at 1 to 2 qts/A) may be added to the spray mixture along with a crop oil concentrate or non-ionic 

surfactant to enhance weed control. The addition of a nitrogen source does not replace the need for crop 

oil concentrate or non-ionic surfactant.

JAR TEST TO DETERMINE COMPATIBILITY OF ADJUVANTS AND V-10233 HERBICIDE

When using V-10233 Herbicide and an adjuvant, such as in stale seed bed or reduced tillage 

situations, a jar test should be performed before mixing commercial quantities of V-10233 Herbicide, 

when using V-10233 Herbicide for the first time, when using new adjuvants or when a new water source 

is being used.

1. Add 1 pt of the water to a quart jar. The water should be from the same source and temperature as 

which will be used in the spray tank mixing operation.

2. Add 1 g of V-10233 Herbicide to the quart jar for every 3 oz of V-10233 Herbicide per acre being 

applied

(2 g if 6 oz/A is the desired V-10233 Herbicide rate), gently mix until product goes into suspension. 

3. Add 60 ml (4 Tbsps or 2 fl oz) of the crop oil or methylated seed oil to the quart jar or 

1 ml of non-ionic surfactant if it is being used in place of oil, gently mix.

4. If nitrogen is being used, add 16 ml (1 Tbsp or 0.5 oz) of the 28 to 32% nitrogen source to the quart 

jar. If ammonium sulfate is being used, add 19 g AMS to the quart jar in place of the 28 to 32% 

nitrogen.

5. Place cap on jar, invert 10 times, let stand for 15 minutes, evaluate.

6. An ideal tank mix combination will be uniform and free of suspended particles. If any of the following 

conditions are observed the choice of adjuvant should be questioned:

a) Layer of oil or globules on the mixture’s surface.

b) Flocculation: fine particles in suspension or as a layer on the bottom of the jar.

c) Clabbering: Thickening texture (coagulated) like gelatin.

DIRECTIONS FOR USE TO MAINTAIN BARE GROUND ON NON-CROP AREAS 

V-10233 Herbicide, when used as directed, can be used for non-selective vegetation control to maintain 

bare ground non-crop areas that must be kept weed-free. Apply V-10233 Herbicide only to:

Bare ground under guardrails, pipelines, railroad beds, railroad yards and surrounding areas

Bare ground in parking and storage areas, plant sites, substations, pumping stations, and tank 

farms

Bare ground areas of airports, brickyards, industrial plant sites, lumber yards and military 

installations, and storage areas 

Bare ground around farm buildings and along ungrazed fencerows, wind breaks, and shelter belts

Road surfaces, improved roadside areas and gravel shoulders

V-10233 Herbicide offers residual and postemergence control of susceptible broadleaf and grass 

weeds as well as an additional mode of action to assist in the control of ALS (acetolactate synthase) 

resistant weeds listed in Table 1, Weeds Controlled or Suppressed by Residual Activity of V-10233 

Herbicide. V-10233 Herbicide can be tank mixed with the herbicides listed in Table 2 for increased 

residual or postemergence control. The length of residual control is dependent on the rate applied as 

well as on rainfall and temperature conditions. Length of residual control will decrease as temperature 

and precipitation increase. 

PREEMERGENCE APPLICATION

Apply 10 oz of V-10233 Herbicide per broadcast acre as a preemergence application on all soil types 

(up to 5% organic matter). Make the preemergence (to weed emergence) applications of V-10233 

Herbicide to a weed-free soil surface. Preemergence applications of V-10233 Herbicide must be 

completed prior to weed emergence. Moisture is necessary to activate V-10233 Herbicide on soil for 

residual weed control. Dry weather following application of V-10233 Herbicide may reduce 

effectiveness. However, when adequate moisture is received after dry conditions, V-10233 Herbicide

will control susceptible germinating weeds.
43

POSTEMERGENCE APPLICATION

Apply 10 oz of V-10233 Herbicide per broadcast acre plus an adjuvant (0.25% v/v non-ionic surfactant 

or 1 qt./A crop oil concentrate). The addition of an adjuvant enhances V-10233 Herbicide activity on 

emerged weeds. Thorough spray coverage is necessary to maximize the postemergence activity of 

V-10233 Herbicide. Emerged weeds are controlled postemergence with V-10233 Herbicide, however, 

translocation of V-10233 Herbicide within a weed is limited, and control is affected by spray coverage 

and by the addition of an adjuvant. The most effective postemergence weed control with V-10233 

Herbicide occurs when applied in combination with a surfactant to weeds less than 2 inches in height. 

Use a a tank mix partner in combination with V-10233 Herbicide for the postemergence control of weeds 

larger than 2 inches. Recommended tank mix partners are listed in Table 2, Suggested Tank Mix 

Combinations For Non-Selective Vegetation Control. 

IMPORTANT: Completely read and follow the label of any potential tank mix partner with V-10233 

Herbicide. When using tank mixtures, use conditions must be in accordance with the most restrictive 

of the label limitations and precautions on either herbicide label.
