PRODUCT INFORMATION 
DEFINE™ DF Herbicide is a selective herbicide for control of many annual grasses and certain broadleaf weeds in field corn, white corn, 
corn grown for silage, field corn grown for seed, sweet corn, and soybeans. DEFINE™ may be applied preplant surface, preplant 
incorporated (mix into the top 1 to 2 inch layer of soil), preeme rgence and/or early postemergence. DEFINE™ will provide its mos t 
effective weed control when applied and subsequently moved into th e soil by rainfall, sprinkler irrigation or mechanical tillag e prior to 
weed emergence. 
DEFINE™ DF Herbicide may be applied using either water or sprayable fluid fertilizer as a liquid carrier. 
DEFINE™ DF Herbicide may be applied either alone or in tank mix combination with additional herbicides. When tank mixing, always 
observe all precautionary statements and limitations on labeling of all products. 
Dry weather following preemergence application of DEFINE™ or recommended tank mixtures may reduce effectiveness. Cultivate if 
weeds develop. 
USE RESTRICTIONS 
DEFINE™ DF Herbicide is for use on soybeans, field corn, white corn, corn grown for silage, field corn grown for seed, and sweet corn. 
DO NOT use on popcorn. 
DO NOT apply this product through any type of irrigation system. DO NOT apply aerially. 
DO NOT use flood irrigation to apply, activate or incorporate DEFINE™ DF Herbicide. 
DO NOT apply more than 21 ounces DEFINE™ DF Herbicide per acre per year in corn and 12 ounces per acre per year in soybeans. 
DO NOT make a postemergence application of DEFINE™ DF Herbicide to corn beyond the 5th leaf collar growth stage (begin count with 
the 1st leaf-rounded tip). 
DO NOT harvest corn forage (silage) within 75 days after a postemergence application. 
Corn and soybean seed should be planted a minimum of 1 to 1-1/2 inches deep. 
If any crop treated with DEFINE™ DF Herbicide is lost, corn or soybeans may be replanted immediately. DO NOT make a second 
application of DEFINE™. 
This product may not be mixed or loaded within 50 feet of any wells (including abandoned wells and drainage wells), sink holes, 
perennial or intermittent streams and rivers, and natural or impounded lakes and reservoirs. This setback does not apply to properly 
capped or plugged abandoned wells and does not apply to impervious pad or properly diked mixing / loading areas. 
Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application equipment or 
containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the 
heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any 
product spills or equipment leaks, container or equipment rinse or washwater, and rainwater that may fall on the pad. Surface water 
shall not be allowed to either flow over or from the pad, which means the pad must be self contained. The pad shall be sloped to 
facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest 
pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude

precipitation from contact with the pad shall have a minimum containment capacity of 100% of the capacity of the largest pesticide 
container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above 
specific minimum containment capacities DO NOT apply to vehicles when delivering pesticide shipments to the mixing / loading site. 
States may have in effect additional requirements regarding wellhead setbacks and operational containment. 
This product must be used in a manner which will prevent back siphoning in wells, spills or improper disposal of excess pesticide, spray 
mixtures or rinsates. 
 
SPRAY DRIFT 
 
1. When using ground application equipment, apply with nozzle height no more than 4 feet above the ground or crop 
canopy. 
2. Applicators are required to use Medium droplet size (ASABE S572.1). 
3. DO NOT apply when wind speeds exceed 10 miles per hour at the application site. 
4. DO NOT apply during temperature inversions. 
 
 
SPRAY DRIFT ADVISORIES 
 
The interaction of many equipment and weather-related factors det ermines the potential for spray drift. The applicator is 
responsible for considering all these factors when making application decisions. 
 
IMPORTANCE OF DROPLET SIZE 
The most effective way to reduce drift potential is to apply la rge droplets. The best drift management strategy is to apply the 
largest droplets that provide sufficient coverage and control. The presence of sensitive species nearby, the environmental 
conditions, and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS 
REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER 
UNFAVORABLE ENVIRONMENTAL CONDITIONS! See Wind, Temperature and Humidity, and Temperature Inversions sections 
of this label. 
 
Controlling Droplet Size 
x Volume - Use high flow rate nozzles to apply the highest practical spray volume . Nozzles with higher rated flows produce 
larger droplets. 
x Pressure - Use the lower spray pressures recommended for th e nozzle. Higher pressure reduces droplet size and does 
not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER- CAPACITY NOZZLE 
INSTEAD OF INCREASING PRESSURE. 
x Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray 
angles produce larger droplets. Consider using low-drift nozzles. 
 
BOOM HEIGHT 
Setting the boom at the lowest referenced height (if specified) which provides uniform coverage reduces the exposure of droplets 
to evaporation and wind. For ground equipment, the boom should remain level with the crop and have minimal bounce. 
 
WIND 
Drift potential increases at wind speeds of less than 3 mph (due to inversion potential) or more than 10 mph. However, many 
factors, including droplet size and equipment type determine drift potential at any given wind speed. AVOID APPLICATIONS 
DURING GUSTY OR WINDLESS CONDITIONS. 
Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affe ct 
spray drift. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects of evaporation. 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature inversions restrict vertical air mixing, which causes small 
suspended droplets to remain close to the ground and move laterally in a concentrated cloud. Temperature inversions are 
characterized by increasing temperature 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 concentrated cloud (under low wind conditions) indicates an inversion, while 
smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to verify 
that the shields are preventing drift and not interfering with uniform deposition of the product.

POLLINATOR ADVISORY STATEMENT 
This product contains an herbicide, therefore follow all label directions and precautions to minimize potential off-target exp osure 
in order to prevent effects to non-target plants adjacent to th e treated site which may serve as habitat or forage for pollinat ors, 
including monarch butterflies (and larvae), birds, and bats. 
 
RESISTANCE MANAGEMENT 
DEFINE™ DF Herbicide is a Group 15 Herbicide (inhibition of very long chain fatty acids). A given weed population may contain or 
develop resistance to a herbicide after repeated use. Appropriate resistance-management strategies should be followed to mitigate or 
delay resistance. The following Integrated Weed Management Techniques are effective in reducing problems with herbicide resistant 
weed biotypes. It is best to use multiple practices to manage or delay resistance, as no single strategy is likely to be totally effective. 
 
x Rotate crops. Crop rotation diversifies weed management. 
x Rotate herbicide-tolerant traits. Alternate herbicide-tolerant (HT) traits and/or use HT trait stacks for more efficient rotation. 
x Use multiple herbicide sites of action. Use tankmix partners and multiple SOAs during both the growing season and from 
year to year to reduce the selection pressure of a single SOA. 
x Know your weeds, know your fields. Closely monitor problematic areas with difficult-to-control weeds or dense weed 
populations. User should scout before and after application. 
x Start with clean fields. Effective tillage or the use of a burndown herbicide program can control emerged weeds prior to 
planting. 
x Stay clean – use residual herbicides. Regardless of tillage system, pre-emergence or early post-emergence soil-applied 
residual herbicides should be used when possible. 
x Apply herbicides correctly. Ensure proper application, including timing, full use-rates and appropriate spray volumes. 
x Control weed escapes. Consider spot herbicide applications, row wicking, cultivation or hand removal of weeds or other 
techniques to stop weed seed production and improve weed management. 
x Zero tolerance – reduce the seed bank. DO NOT allow surviving weeds to set seed, which will help decrease weed 
populations from year to year and prevent major weed shifts. 
x Clean equipment. Prevent the spread of herbicide-resistant weeds and their seeds.

MIXING INSTRUCTIONS 
LIQUID CARRIERS: 
DEFINE™ DF Herbicide is a dry flowable herbicide that must be mixed in water or sprayable fluid fertilizer. Compatibility of DEFINE™ 
or its labeled tank mix products with these liquid carriers should always be predetermined prior to spraying. Refer to the SPRAYABLE 
FLUID FERTILIZER COMPATIBILITY TEST (Appendix I) of this label to determine product compatibility in fluid fertilizer carriers. 
Before mixing DEFINE™ DF Herbicide and its labeled tank mixtures, examine the spray equipment making sure it is completely clean 
and free of rust or corrosion. Be sure the equipment is free of any residues from previously used pesticides. Flush lines with clean 
water or recommended detergents after the last application. Use an approved method for disposing of rinsate. 
For optimum spray tank mixing and efficacy, DEFINE™ DF Herbicide is recommended to be added to the spray tank via an eductor 
system. 
The proper mixing sequence for DEFINE™ DF Herbicide and recommended tank mixtures with the appropriate liquid carrier is as 
follows: 
1. Fill the spray tank or nurse tank 1/4 full with the appropriate liquid carrier. 
2. Start recirculation and agitation system and continue throughout mixing and application. 
3. If the compatibility test indicates the need of a compatib ility agent, add the recommended amount of compatibility agent to the 
spray tank. 
4. If ammonium sulfate is to be used, add it now.

6 
 
5. Next add the specified quantity of DEFINE™ DF Herbicide through the eductor or to the spray tank [slowly add DEFINE™ if water 
or sprayable grade nitrogen fertilizers (28-0-0, 32-0-0) are the carriers; for other sprayable grade fertilizers first check compatibility 
and then either mix directly or preslurry in water depending in the results of the compatibility test]. 
6. If tank mixing with wettable powders or other dry flowable products in water, they may be added now. 
 If tank mixing these products in a sprayable fertilizer carrier, first make a slurry of the products with water and then add the slurry 
slowly to the spray tank. 
7. If tank mixing with emulsifiable concentrates or soluble products, add the products to the spray tank. 
8. If tank mixing with a glyphosate- containing product or Touchdown®, add the products to the spray tank. 
9. If mixing spray adjuvants in the mixture, add them after all other products have been mixed. 
10. Fill the spray tank to the desired level with the appropriate liquid carrier. 
11. Continue agitation during transport and application until the spray tank is empty. 
DEFINE™ DF Herbicide and all registered mixtures should be kept agitated once mixed and then sprayed immediately. DO NOT allow 
mixtures to stand for prolonged periods of time. Water quality, pH, temperature and/or other components of the mixture may affect how 
long the mixture may stand before application. 
APPLICATION INFORMATION 
SPRAYER APPLICATION 
Ground Broadcast Treatment: Accurately calibrate the sprayer prior to mixing the herbicide treatments. Apply DEFINE™ DF 
Herbicide and the labeled tank mixtures in a minimum of 10 gallons of total spray volume per acre using broadcast boom equipment. 
Use a pump with capacity to maintain 30 to 40 psi at the nozzles, maintain adequate in-tank agitation to keep the spray mixture in 
suspension and provide a minimum of 20% bypass at all times. If mixed with other labeled herbicides, the spray volume may be no 
less than the minimum volume specified by the tank mix product or 10 gallons, whichever is greater. The use of screens to protect the 
pump and nozzles is recommended. Screens placed on the suction side of the pump should be 16-mesh or coarser. DO NOT place a 
screen in the recirculation line. Use 50-mesh or coarser screens between the pump and boom, and where required, at the nozzles. 
Refer to the nozzle manufacturer for additional recommendations. Agitate thoroughly before and during application with either bypass 
or mechanical agitation. Rinse the sprayer thoroughly with clean water immediately after each use. 
Band Treatment: DEFINE™ DF Herbicide and the labeled tank mixtures may be applied as a band treatment. Use the following 
formula to calculate the amount of herbicide needed for band treatments: 
 Band width in inches X Broadcast rate = Band rate 
 Row width in inches per acre per acre 
APPLICATION METHODS AND TIMING 
DEFINE™ DF Herbicide may be applied either alone or in tank mixtures with or sequentially with certain other registered and 
recommended herbicides provided that, for tank mixes, the tank mix product label does not prohibit such mixing. Applications may be 
made preplant surface, preplant incorporated or preemergence. DEFINE™ may be used in either a single or split application program. 
Preplant Surface: For use in conservation, minimum or no- tillage crop production systems, DEFINE™ DF Herbicide alone or as a 
recommended tank mixture may be applied as a broadcast spray up to 45 days before planting in corn and 14 days before planting in 
soybeans. A sequential application is recommended for applications made 30 to 45 days prior to planting, where 2/3 of the highest 
specified broadcast rate for the crop and soil texture is applied initially and the remaining 1/3 is applied at planting. Treatments made 
less than 30 days before planting may use either a single or sequential application. If weeds are present at the time of application, 
apply the DEFINE™ DF Herbicide treatment in tank mixture with a recommended nonselective herbicide. If possible, DO NOT move 
treated soil out of the row or move untreated soil to the soil surface during planting, as weed control may be reduced. 
Preplant Incorporation: Apply DEFINE™ DF Herbicide alone or in combination with recommended tank mixes as a broadcast spray 
and incorporate into the upper 1 to 2 inches of the soil surface up to 14 days before planting. Avoid deep incorporation since reduced 
weed control and/or crop injury may result. Incorporate with implements which provide uniform, shallow incorporation (example -
finishing disk, harrow, rolling cultivator, etc.) 
Preemergence: DEFINE™ DF Herbicide alone and its recommended tank mixes may be applied to the soil surface as a broadcast 
spray or band application after planting of the crop but prior to weed or crop emergence. If weeds are present at the time of application, 
apply DEFINE™ with a nonselective herbicide . Rainfall and/or overhead sprinkler irrigation is necessary to move DEFINE™ into the 
upper soil surface where weed seeds germinate. Dry weather conditio ns following application may reduce weed control. If adequ ate 
moisture is not received within 7 to 10 days after applications and weeds begin to emerge from the soil, a light rotary hoeing or shallow 
incorporation (no deeper than 1/2 inch deep) will improve performa nce and minimize crop damage. Excessive rainfall or irrigati on after 
application may reduce weed control. 
Early Postemergence: When used as an early postemergence treatment, DEFINE™ DF Herbicide may be applied once per year alone 
or in combination with or sequentially with certain herbicides. Use of an adjuvant is recommended in some applications. Refer to crop 
sections of the label for specific information. 
Special Applications: Fall Application (for use only in IA, MN, ND, SD, WI, north of Route 20 in NE, north of Route 136 in IL, and north 
of Interstate 70 in OH):

7 
 
Following harvest of crops in the fall, DEFINE™ DF Herbicide may be applied to crop s tubble after October 15, when the sustained soil 
temperature at the four-inch soil depth is less than 50 oF, but before the ground is frozen. This application is limited to only medium- and 
fine-textured soils with an organic matter of 2.5% or greater and which will be planted to corn the following spring. The soil may be tilled 
before or after application with incorporation depth no more than two to three inches following herbicide application. If a spring application 
of DEFINE™ DF Herbicide follows the fall application, the total DEFINE™ rate for both applications must not exceed 21 ounces. 
CORN 
(Field, Seed, and Sweet Corn) 
DEFINE™ dry flowable herbicide is a selective herbicide for control of most annual grasses and selected annual broadleaf weeds in corn. 
A maximum of two applications may be made alone or in tank-mix combination with certain registered herbicides. The following types of 
applications are allowed: preplant surface, preplant incorporated, preemergence and early postemergence. Most effective weed control 
will occur when the applied product is moved into the soil by rainfa ll, sprinkler irrigation or mechanical tillage prior to wee d emergence 
from the soil. 
For pre-emergent use in corn: The REI is 12 hours. For post-emergent use in corn: The REI is 4 days for hand-set irrigation and 24 hours 
for all other activities. 
Special Precautions ( Field Seed Corn Inbreds): Field seed corn inbred lines and sweet corn varieties may vary in their response to 
DEFINE™ DF Herbicide. DO NOT apply DEFINE™ to inbreds without first verifying with your local seed corn company (supplier) the 
DEFINE™ selectivity on your inbred line. 
WEED SPECIES CONTROLLED BY DEFINE™ DF HERBICIDE 
DEFINE™ DF Herbicide applied at specified dosages and application timings will control many important annual grasses and broadleaf 
weeds.

DEFINE™ DF HERBICIDE USE RATES IN PREPLANT SURFACE, PREPLANT INCORPORATED, PREEMERGENCE 
AND EARLY POSTEMERGENCE APPLICATIONS 
For FALL Application ( For use only in IA, MN, ND, SD, WI, north of Route 20 in NE, north of Route 136 in IL, and north of 
Interstate 70 in OH): 
 After October 15, when the sustained soil temperature at the four inch soil depth is less than 50 oF, DEFINE™ DF Herbicide may be 
applied to remaining crop stubble following harvest. In conservation, minimum and no-tillage systems on soils having 2.5% organic 
matter or greater, apply DEFINE™ at 19 to 21 oz/A on medium textured soils and 21 oz/A on fine textured soils. Apply before the 
ground is frozen. The soil may be tilled before or after application with an incorporation depth no more than two to three inches 
following the fall application. Minimize furrow and ridge formation in the tillage operations after application of DEFINE™. If a spring 
application is made, the total rate of both fall and spring must not exceed the maximum total rate for corn, or illegal residues may occur. 
For CONVENTIONAL Tillage Systems With Applications Made TWO WEEKS OR LESS Preplant Surface, Preplant Incorporated 
or Preemergence: 
DEFINE™ DF Herbicide use rates are located in Table 1. 
Rates are based on soil texture and organic matter and are for applications made within two weeks of planting and until corn 
emergence. DO NOT use on peat or muck soils (soils with 20% or more organic matter).

heavy weed pressure and/or when soil organic matter is at the upper end of the range. 
2 For more information, refer to the "Rate Selection/Soil Texture" section of this label. 
For CONSERVATION, MINIMUM, and NO-TILLAGE Systems; or CONVENTIONAL Tillage Systems With Applications GREATER 
THAN TWO WEEKS Preplant: 
DEFINE™ DF Herbicide use rates are located in Table 2. Rates are higher for these types of tillage systems and application timings 
than in Table 1 due to the extended period of weed control needed and the increased crop residue present. Refer to the “Application 
Methods and Timing” section of the label for details. Weed control will generally be greater the closer the applications are made to 
planting but prior to weed emergence. If weeds are present at application, a nonselective herbicide such as a glyphosate-containing 
product or Touchdown used at specified rates may be mixed with DEFINE™ DF Herbicide treatments. DO NOT use on peat or muck 
soils (soils with 20% or more organic matter).

FOR EARLY POSTEMERGENCE APPLICATIONS: 
DEFINE™ DF Herbicide use rates are located in Table 1. 
DEFINE™ DF Herbicide alone and/or certain DEFINE™ tank mixtures may be applied to corn from emergence through the 5 th leaf collar 
growth stage. Begin leaf count with the first leaf (rounded tip). DEFINE™ alone will not provide control of emerged weeds. For control of 
emerged weeds, DEFINE™ may be tank mixed with approved postemergence herbicides. Read and follow all precautions/restrictions 
and directions on tank mix partner labels. 
Corn treated with DEFINE™ DF Herbicide early postemergence may be harvested for forage (silage) 75 days or more after treatment. 
Adjuvants for early postemergence: 
The adjuvant types listed below may be utilized with DEFINE™ DF Herbicide. 
UAN (urea ammonium nitrate) is commonly referred to as 28, 30, or 32%N. UAN can be used as an adjuvant in certain herbicide tank 
mixtures with DEFINE™, or as a spray carrier for DEFINE™. Fluid fertilizers applied after crop emergence can result in crop tissue 
“burn” symptoms. Using fluid fertilizer as a postemergence spray carrier to apply DEFINE™ is not recommended if fluid fertilizer burn is 
not considered acceptable. 
Ammonium sulfate (spray grade) is recommended as an alternative to UAN as a spray solution adjuvant with certain tank mixture 
partners. 
When tank mixing DEFINE™ DF Herbicide with other herbicides be certain to select adjuvants recommended and compatible for use 
with all herbicides included in the tank mixture.

SOYBEAN 
DEFINE™ DF Herbicide is a selective herbicide for control/suppre ssion of most annual grasses in soybeans. DEFINE™ DF Herbici de 
may be applied once per year either alone, in tank mix combination with or sequentially with certain registered herbicides. The following 
types of application are allowed: preplant surface, preplant inco rporated and preemergence. The preplant surface and preplant 
incorporated treatments may be applied up to 14 days before planting. The most effective weed control will occur when the appl ied 
product is moved into the soil by rainfall, sprinkler irrigation or mechanical tillage prior to weed emergence form the soil. 
DO NOT graze or feed forage, hay or straw to livestock. 
For pre-emergent use in soybeans: The REI is 12 hours. For post-emergent use in soybeans: The REI is 2 days. 
 
WEED SPECIES CONTROLLED BY DEFINE™ DF HERBICIDE

APPENDIX I 
SPRAYABLE FLUID FERTILIZER COMPATIBILITY TEST 
A compatibility test is highly recommended for all applications with liquid fertilizers. Prior to mixing products in the spray tank, small 
quantities of each product can be mixed in proportionate quantities to evaluate compatibilities. The following test assumes a spray 
volume of 25 gallons per acre. If other spray volumes are to be used, adjust the appropriate amounts of ingredients. To check for 
compatibility, use the following procedure: 
1. Add two inches of the liquid carrier (water or liquid fertilizer) to a one-quart jar fitted with a tight lid. 
2. Add the appropriate amount of herbicide. If more than one product is used, the recommended mix sequence is the dry herbicide first, 
flowables next and emulsified concentrates last. For dry herbicides, add 1-1/2 level teaspoons/pound/acre use rate and for liquids 
add 1/2 teaspoon/pint/acre use rate. 
3. Add one pint of the liquid carrier (water or liquid fertilizer) to the jar. Place the lid on the jar and gently shake the jar for one minute. 
Place the jar on a level surface and let it stand for 30 minutes. 
4. Reagitate the mixture and observe the mixture for signs of phase separation, flakes, particles, gels, precipitates, etc. If none of these 
conditions occur, the mix is compatible. 
5. If incompatible, use of a compatibility agent is recommended. Rerun the above test but first add a compatibility agent (1/4 teaspoon 
is equal to a use rate of 2 pints/100 gallons spray mix) and gently shake the jar prior to adding herbicides. 
6. If the mixture is now compatible, a compatibility agent should be used in the spray mixture at its recommended rate. 
7. If the components of the solution are still incompatible, the mixture should not be attempted for use in the spray tank. 
8. Contact your Bayer CropScience representative for further recommendations on testing spray solution compatibilities.
