USE INFORMATION 
Kochiavore is an emulsifiable concentrate that provides selective postemergence control of broadleaf 
weeds in wheat, barley, corn and sorghum and non-cropland areas, including Conservation Reserve 
Program land and fallowland.

4 
 
WEED RESISTANCE MANAGEMENT 
Kochiavore is a premix of two Group 4 and one Group 6 herbicides. Any weed population may contain 
plants naturally resistant to Group 4 and/or Group 6 herbicides. The resistant biotypes may dominate the 
weed population if these herbicides are used repeatedly in the same field. Appropriate resistance-
management strategies should be followed. 
 
To delay herbicide resistance, take one or more of the following steps: 
x Rotate the use of this product or other Group 4 and Group 6 herbicides, within a growing season 
sequence or among growing seasons, with different herbicide groups that control the same weeds in 
a field. 
x Use tank mixtures with herbicides from a different group if such use is permitted; where information 
on resistance in target weed species is available use the less resistance-prone partner at a rate that 
will control the target weed(s) equally as well as the more resistance-prone partner. Consult your 
local extension service or certified crop advisor if you are unsure as to which active ingredient is 
currently less prone to resistance. 
x Adopt an integrated weed-management program for herbicide use that includes scouting and uses 
historical information related to herbicide use and crop rotation, and that considers tillage (or other 
mechanical control methods), cultural (e.g., higher crop seeding rates; precision fertilizer application 
method and timing to favor the crop and not the weeds), biological (weed-competitive crops or 
varieties) and other management practices. 
x Scout fields prior to application to identify the weed species present and their growth stage to 
determine if the intended application will be effective. 
x Scout fields after herbicide application to monitor weed populations for early signs of resistance 
development. Indicators of possible herbicide resistance include: 
o Failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds. 
o A spreading patch of non-controlled plants of a particular weed species. 
o Surviving plants mixed with controlled individuals of the same species. 
If resistance is suspected, prevent weed seed production in the affected area by an alternative 
herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent 
movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when 
moving between fields, and planting clean seed. 
x If a weed pest population continues to progress after treatment with this product, discontinue use of 
this product, and switch to another management strategy or herbicide with a different mode of action, 
if available. 
x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC 
representative for pesticide resistance management and/or integrated weed management 
recommendations for specific crops and resistant weed biotypes. 
x For further information or to report suspected resistance, contact your Winfield Solutions, LLC 
representative.

SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF 
NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
 
IMPORTANCE OF DROPLET SIZE 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target 
pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if 
applications are made improperly or under unfavorable environmental conditions. 
 
Controlling Droplet Size – Ground Boom 
• Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use 
the highest practical spray volume for the application. If a greater spray volume is needed, consider using 
a nozzle with a higher flow rate.

6 
 
 
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume 
and droplet size. 
 
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles 
designed to reduce drift. 
 
Controlling Droplet Size – Aircraft 
• Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. Generally, to 
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. 
 
BOOM HEIGHT – Ground Boom 
For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
RELEASE HEIGHT - Aircraft 
Higher release heights increase the potential for spray drift. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify 
that the shields are not interfering with the uniform deposition of the spray on the target area. 
 
Boomless Ground Applications 
Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. 
 
Handheld Technology Applications 
Take precautions to minimize spray drift. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation. 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature inversions are characterized by 
increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. 
The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground 
source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud 
(under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates 
indicates good vertical air mixing. 
 
WIND 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray 
drift. 
 
MIXING INSTRUCTIONS 
This product may be tank mixed with other products at specified rates as long as tank mixing is not 
prohibited by the label(s) of the tank mix partner products, or as otherwise noted within the specific crop 
use directions for this product, and the tank mix partner products are labeled for the timing and method of 
application for the use site to be treated. If compatibility with another product is not known, perform a (jar) 
test to determine compatibility (see below). 
 
This product can be mixed with some liquid fertilizers or liquid iron materials. Because liquid fertilizers and 
liquid iron differ in pH, free ammonia content, density, salt concentration and percentage of water, a 
compatibility test (see below) is recommended prior to mixing in the application equipment. All regulations, 
either State or Federal, relating to the application of liquid fertilizers or liquid iron and this product must be 
strictly followed.

7 
 
 
Tank Mixing Precautions 
x Follow all applicable directions, restrictions and precautions that appear on the respective tank mix 
product labels. 
x Do not exceed specified application rates. Do NOT tank mix with other pesticide products that 
contain the same active ingredient as this product unless the label of either mix partner specifies 
the maximum dosages that may be applied. 
x Prior to final use, perform a (jar) test to verify the compatibility of tank mix partner products (see 
below). 
 
Tank Mix Compatibility (Jar) Test 
The following jar test is recommended prior to tank mixing to ensure the compatibility of this product with 
other tank mix partner products: 
1) Mix the desired tank mix ingredients in their relative proportions in a clear glass quart jar with lid. 
2) Invert the jar containing the mixture several times and observe the mixture for approximately 1/2 hour. 
3) If the mixture balls-up, forms flakes, sludges, gels, oily films or layers, or other precipitates, it is 
not
 compatible and the tank mix combinations should not be used. 
 
Tank Mixing Instructions 
Note: When adding ingredients to the mixture, allow time for each ingredient to be thoroughly mixed before 
adding the next. 
 
1. Fill spray tank with water equal to 1/4 to 1/3 of the required spray volume and start agitation. 
2. Maintain agitation continuously during mixing, final filling and while applying. 
3. Add different formulation types in the following order, being certain to allow sufficient time for each 
product to completely mix and disperse after addition. Kochiavore is an emulsifiable concentrate 
(EC) formulation. 
 a) dry flowables 
 b) wettable powders 
 c) aqueous suspensions 
 d) flowables or liquids 
4. Maintain agitation and fill spry tank to 3/4 of total spray volume and then add this product, other 
emulsifiable concentrates and any solutions. 
5. Finish filling the spray tank. 
 
While spraying, the tank mix ingredients may settle out of suspension if agitation is stopped before the 
spray tank is empty. The settled materials must be resuspended before any spraying is resumed. Note that 
settled material may be more difficult to resuspend than when originally mixed. 
 
 
APPLICATION TIMING 
Only weeds that have emerged at the time of application will be controlled, therefore, be certain to apply to 
actively growing weeds. Weed control may be reduced and the risk of crop injury (at all stages of growth) 
may increase if extreme growing conditions (such as drought or near-freezing temperatures) occur prior to, 
at, or following application. Control may be decreased if target plant foliage is wet at the time of application. 
Applications of this product are rainfast within 1 hour after application. 
 
Effect of Temperature on Herbicidal Activity 
The herbicidal activity of this product is influenced by weather conditions. Optimum herbicidal activity 
requires active plant growth and temperatures between 55°F to 75°F. Reduced efficacy will occur when 
temperatures are below 45°F or above 85°F. Weed control and crop tolerance may be reduced if frost 
occurs before or shortly after application (3 days). 
 
SPRAY COVERAGE 
Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. For best results 
(and to minimize spray drift), apply in a spray volume of 8 gallons or more per acre by ground and 3 or 
more gallons of total spray volume per acre by air. Spray volume should be increased as weed density and 
vegetative canopy increase in order to obtain equivalent weed control; however, do not exceed 40 gallons

8 
 
per acre total spray volume. Rather than increasing boom pressure, decrease spraying speed or use larger 
nozzle tips to increase spray volume. 
 
Use only nozzle types and spray equipment designed for herbicide application. To reduce spray drift, be 
certain to follow the precautions under the heading, “Spray Drift Management”. 
 
Adjuvants 
Unless otherwise noted within the specific crop and non-cropland use directions, a high-quality adjuvant 
may be used to improve weed control. An adjuvant can optimize herbicidal activity when applications are 
made at lower carrier volumes, under conditions of cool temperature, low relative humidity or drought, or to 
small, heavily pubescent kochia. When an adjuvant is to be used with this product, Winfield Solutions, 
LLC recommends the use of a Council of Producers & Distributors of Agrotechnology (CPDA) certified 
adjuvant. 
 
Spot Treatments 
Only apply using a calibrated boom sprayer using the directions below. Application rates in the table below 
are based on an area of 1,000 square feet. 
 
Do not apply with backpack or hand-held application equipment. 
 
Mix the amount of this product (fluid ounces or ml) corresponding to the desired broadcast rate in one or 
more gallons of spray. To calculate the amount of this product required for larger areas, multiply the table 
value (fluid ounces or ml) by the area to be treated in “thousands” of square feet. An area of 1,000 square 
feet is approximately 10.5 X 10.5 yards (strides) in size. 
 
For example: If the area to be treated is 3,500 square feet, multiply the table value by 3.5 (calc. 3,500 ÷ 
1,000 + 3.5).

APPLICATION RATES 
In general, the application rates at the lower end of the specified rate range will be efficacious when applied 
to susceptible weed species with young, succulent growth. Use the higher rates within the rate range when 
applying to less sensitive species, perennials, and under conditions where control is more difficult (e.g., 
when plants are stressed due to drought or extreme temperatures, in dense weed stands and/or the weeds 
are larger). The higher rates will also be needed to control or suppress weeds in areas where competition 
from crops is not present (e.g., fallowland).

†Indicates Suppression Only - Suppression is a reduction in weed competition (reduction is population or 
vigor) as compared to untreated areas. The degree of weed control and duration of effect may vary with 
weed size, density, application rate, coverage, and growing conditions before, during and after treatment. 
 
1Includes biotypes that are herbicide-resistant or tolerant. Weeds germinating after spraying will not be 
controlled. 
 
Management of Kochia Biotypes 
Research indicates many biotypes of kochia may occur within a single field and while kochia biotypes can 
vary in their susceptibility to this product, in general all biotypes will be suppressed or controlled at the 
labeled rate of 1 to 1-1/2 pints per acre. A shift to more tolerant biotypes within a field may occur if this 
product is applied at rates lower than specified. 
 
Practices for Resistance Management 
Extensive populations of dicamba -tolerant kochia have been identified in certain small grain and corn 
production regions (such as Chouteau, Fergus, Liberty, Toole, and Treasure counties in the state of 
Montana). For optimal control of dicamba-tolerant kochia in these counties, apply this product at the rate of 
1-1/2 pints per acre. 
 
To minimize selection pressure and preserve the utility of this product for control of dicamba-tolerant kochia 
biotypes, this product should be rotated with products that do not contain dicamba. 
 
 
CROP USES 
CROP KOCHIAVORE 
APPLICATION RATE 
DIRECTIONS 
BARLEY 
WHEAT 
1 to 1-1/2 pints per acre POSTEMERGENT APPLICATION: Apply from the 4-leaf 
(Zadoks 14) to emergence of the flag leaf (Zadoks 37). Use the 
higher rates when weeds are less susceptible or for heavy 
weed populations. To avoid injury, do not use with atrazine, 
crop oils or other adjuvants, such as non-ionic surfactants. 
Restrictions and limitations for barley and wheat: 
x Do NOT harvest treated forage or allow livestock to graze treated areas within 45 days of 
application. 
x Do NOT feed treated straw to livestock.

10 
 
x The risk of crop injury at all stages of growth and poor weed control is increased if the application 
is made and extreme growing conditions (such as drought or near freezing temperatures) occur 
prior to, at, and following the application. Reduced weed control may also occur during these 
conditions. 
x Do NOT apply when crop canopy covers the weeds as poor control will result. 
x Preharvest Interval (PHI): Do NOT apply within 40 days prior to harvesting grain and straw or 
within 14 days prior to cutting hay. 
x Make no more than one postemergence application per growing season at a maximum of 1.5 
pints 
(0.31 lb. AE 2,4-D; 0.31 lb. AE bromoxynil; 0.13 lb. AE fluroxypyr) per acre per application, up to flag 
leaf emergence stage. 
x Do NOT spray plants beyond the flag leaf emergence stage. 
x Do NOT apply more than 1.5 pints of this product per acre per application. 
x Do NOT apply more than 2.4 pints (0.5 lb. AE 2,4-D, 0.5 lb. AE bromoxynil, 0.2 lb. AE fluroxypyr) of this 
product per acre per year. 
FIELD 
CORN 
1 to 1-1/2 pints per acre PREPLANT APPLICATION: Apply prior to planting. Delay 
planting for a minimum of 7 days after application. Planting 
sooner may result in unacceptable crop injury. Do not perform 
tillage for at least 7 days after application. Do not use on sandy 
soils or unacceptable crop injury may result. 
1 to 1-1/2 pints per acre PREEMERGENCE and REDUCED TILLAGE APPLICATION: 
Make applications after corn is planted but before emergence 
to control emerged broadleaf weeds. Use the higher rates 
when weeds are less susceptible or for heavy weed 
populations. The seed furrow must be completely closed at 
application or severe crop injury may result. Do not use on 
sandy soils or unacceptable crop injury may result. 
1 to 1-1/2 pints per acre POSTEMERGENT APPLICATION: Apply to field corn as a 
broadcast or band treatment from the V3 to the V5 growth 
stages. Application prior to the V3 growth stage may result in 
increased crop leaf burn. Apply with drop nozzles and 
directed spray only from the V6 growth stage. DO NOT apply 
from 2 weeks before tasseling to dough stage. 
 
To avoid crop injury, do not use with atrazine, crop oils or other 
adjuvants, such as non-ionic surfactants. Application during 
high moisture and temperature conditions may cause crop 
injury or brittleness. DO NOT cultivate for a week to 10 days 
after treatment or stalk breakage may occur. Do not use on 
sandy soils or unacceptable crop injury may result. 
Restrictions and limitations for field corn: 
x Do not cut treated crop for feed or fodder or graze for 47 for days following application. 
x Do not harvest within 90 days of application. 
x Seed corn producers should consult the respective seed corn company regarding tolerance of 
certain seed production inbred lines to bromoxynil octanoate. 
x Maximum application of 3.0 pints (0.62 lb. AE 2,4-D; 0.62 lb. AE bromoxynil; 0.26 lb. AE fluroxypyr) per acre 
per year. 
 
Preplant or preemergence: 
x Limited to one preplant or preemergence application per year. 
x Maximum rate of application: 1.5 pints (0.31 lb. AE 2,4-D; 0.31 lb. AE bromoxynil; 0.13 lb. AE fluroxypyr) per 
acre. 
 
Postemergence: 
x Limited to one postemergence application per year. 
x Maximum rate of application: 1.5 pints
 (0.31 lb. AE 2,4-D; 0.31 lb. AE bromoxynil; 0.13 lb. AE fluroxypyr) per 
acre.

SORGHUM, 
GRAIN 
AND 
FORAGE 
 
1 to 1-1/2 pints per acre Apply to sorghum from the V4 but prior to the pre-boot stage. 
Use drop nozzles and directed spray only from the V8 to the 
pre-boot stage. To reduce the potential for crop injury, drop 
nozzles should direct the spray toward the soil surface, to 
avoid spray contact with grain sorghum foliage. Do not apply 
during the boot, flowering or early dough stages. 
 
The higher rate may be needed for some weeds, such as 
perennials or for heavy weed populations, but chances of crop 
injury may increase. To avoid injury, do not use with atrazine, 
crop oils or other adjuvants, such as non-ionic surfactants. 
 
Some sorghum varieties and hybrids are 2,4-D sensitive. Crop 
injury may also be increased by h igh moisture and 
temperature conditions. Contact your seed company or 
Extension Service for advice. 
Restrictions and limitations for sorghum: 
x Do not harvest within 70 days of application. 
x Do not permit meat or dairy animals to consume treated crop as fodder or forage or graze for 45 for 
days following application. 
x Limited to 1 application per year. 
x Maximum of 1.5 pints (0.31 lb. AE 2,4-D; 0.31 lb. AE bromoxynil; 0.13 lb. AE fluroxypyr) per acre per application.

1-1/4 to 2-2/5 Pints per Acre Mix with an adequate amount of water to 
thoroughly saturate all weeds with spray 
mixture. This may require a spray volume of 
50 to 300 gallons of water per acre. Apply any 
time between the time when plants come into 
full leaf (spring) to when the plants begin to go 
dormant. Best results are obtained when 
weeds are young and actively growing. Do not 
cut weeds until herbicide has translocated 
throughout the plant causing root death. For 
small broadleaf weeds, use the lower rate. 
Heavy, dense stands require the higher rate 
with high water volume.
 
 
Use a high surfactant crop oil concentrate such 
as Superb® HC, a high surfactant methylated 
seed oil such as Destiny ® HC or another crop 
oil for improved performance. 
 
Restrictions and limitations: 
x Maximum of 2.4 pints (0.5 lb. AE 2,4-D, 0.5 lb. AE bromoxynil, 0.2 lb. AE fluroxypyr) of product per acre per 
year. 
x Limited to 1 application per year. 
x Do not allow livestock to graze in treated areas or feed treated plant material to livestock. 
x Do not use this product on sod farms 
x Applications to non-cropland areas are not applicable to treatment of commercial timber or other 
plants being grown for sale or other commercial use, or for commercial seed production, or for 
research purposes.

CONSERVATION 
RESERVE 
PROGRAM (CRP) 
LAND 
 
1-1/4 to 2-2/5 Pints per Acre This product may be used for Conservation 
Reserve Programs (CRP), weed and brush 
control or in State Recognized Noxious Weed 
area (noncropland areas). Refer to “Weeds 
Controlled” section for list of susceptible 
species. For areas underseeded with 
alfalfa, do not apply more than 1.5 pints per 
acre per year.
 
 
Some weed species require tank mixes for 
adequate control. Use a high surfactant crop oil 
concentrate such as Superb HC, a high 
surfactant methylated seed oil such as Destiny
 
HC or another crop oil for improved 
performance. 
Restrictions and Limitations: 
x Maximum of 2.4 pints (0.5 lb. AE 2,4-D, 0.5 lb. AE bromoxynil, 0.2 lb. AE fluroxypyr) of product per acre per 
year. Limited to 1 application per year. 
x Do not apply more than 1.5 pints (0.31 lb. AE 2,4-D; 0.31 lb. AE bromoxynil; 0.13 lb. AE fluroxypyr) of product 
per acre per year to CRP areas that are underseeded with alfalfa. 
x Do not add spray adjuvants or fluid fertilizers when applying to CRP areas planted with alfalfa or 
other legumes. 
x Consult the Conservation Reserve Program rules for CRP uses. The more restrictive 
requirements of the program rules or this label must be followed. 
x Do not allow livestock to graze in treated areas or feed treated plant material to livestock. 
 
FALLOWLAND 1-1/4 to 2-2/5 Pints per Acre Unless otherwise specified below, apply when 
broadleaf weeds are up to the 8-leaf stage, 4 
inches in height or 2 inches in diameter, 
whichever comes first. Apply to grasses from 
the 3-leaf stage. Use the higher application 
rate for less susceptible weeds. 
 
Use a high surfactant crop oil concentrate such 
as Superb HC, a high surfactant methylated 
seed oil such as Destiny HC or another crop oil 
for improved performance. 
 
Kochia seedlings less than 4 inches tall 
(including ALS resistant biotypes) will be 
controlled using the 1.25 pint per acre rate. 
However, when conditions for control are less 
favorable, such as under drought or cool 
temperature, a rate of 1.5 pints per acre will 
provide more consistent control of kochia 
seedlings 1 to 4 inches tall. For more 
consistent control of small kochia, apply when 
the plants are at least 1 inch tall. A rate of 1.5 
pints per acre should be used for optimal 
control of dicamba tolerant kochia populations 
(refer to the “Management of Kochia Biotypes” 
in the “Application Information” section above). 
Restrictions and Limitations: 
x Do not allow livestock to graze in treated areas or feed treated grass to livestock. 
x Limited to two applications per year. 
x Minimum of 30 days between applications. 
x Do not apply more than 2.4 pints (0.5 lb. AE 2,4-D, 0.5 lb. AE bromoxynil, 0.2 lb. AE fluroxypyr) of this 
product per acre per year.
