GENERAL INFORMATION 
BRONATE® is formulated as an emulsifiable concentrate containing the equivalent of 2 Ibs. per gallon of octanoic acid ester of 
bromoxynil and 2 pounds per gallon of isooctyl ester of MCPA. 
BRONATE® is a selective postemergence herbicide for control of important broadleaf weeds infesting wheat, barley, oats and rye, 
conservative reserve program areas, and grass grown for seed or sod production. Optimum weed control is obtained when 
BRONATE® is applied to actively growing weed seedlings. BRONATE® is primarily a contact herbicide, therefore thorough coverage of 
the weed seedlings is essential for optimum control. 
BRONATE® has little residual activity. Therefore subsequent flushes of weeds will not be controlled by the initial treatment. Generally 
crops that form a good canopy will help shade subsequent weed flushes. However, certain crops or short-straw varieties, for example 
Yaccora Rajo wheat, may not develop the crop canopy fast enough to shade the subsequent flushes of weeds. 
Occasional transitory leaf bum may occur. The temporary leaf bum is similar to that seen with liquid fertilizer. Because the activity of 
BRONATE® is mainly contact, recovery of the crop is generally rapid with no lasting effect. Frequency and amount of leaf bum may be 
greater when crops are stressed by abrasive winds, cool to cold evening temperatures or mechanical injury, such as that caused by 
hail, sleet or insect feeding. To reduce the potential for temporary leaf bum, applications should be made to dry foliage in the 
recommended spray volumes per acre when weather conditions are not extreme. 
MIXING, LOADING AND HANDLING INSTRUCTIONS 
2.5 Gallon Containers 
It is strongly recommended that special care be taken in mixing and loading this product. Hands should be placed on the container in 
such a way as to avoid possible drip or splash. Correct procedures for mixing and loading are provided in Bayer CropScience's 
Educational Program. 
30 Gallon and Bulk Containers 
If you will handle a total of 60 gallons or more of this product per day, you must use a mechanical transfer system for a/l mixing and 
loading operations. If this product is packaged in a 30 gallon drum, you must use a mechanical transfer system which terminates in a 
drip-free hard coupling which may be used only with a spray or mix tank which has been fitted with a compatible coupling. If you do not 
presently own or have access to a mechanical transfer system with this type of coupling, contact your dealer for information on how to 
obtain such a system or to modify your present system. When using a mechanical transfer system, do not remove or disconnect the 
pump or probe from the container until the container has been emptied and rinsed. The pump or probe system must be used to rinse 
4

the empty container and to transfer the rinsate directly to the mixing or spray tank. 
BRONATE® ALONE: Fill the spray tank 1/2 to 3/4 full with clean water. Begin agitation and add the recommended amount of 
BRONATE®. Add water to the spray tank to the desired level. Maintain sufficient agitation to ensure a uniform spray mixture during 
application. 
TANK MIXTURES: BRONAT~ may be tank-mixed with other pesticide products provided that these other products are registered for 
use on the crop/use site to be treated. The tank mix must be used in accordance with the more restrictive pesticide label limitations and 
precautions. No label dosage rates may be exceeded. Bronate cannot be mixed with any product containing a label prohibition against 
such mixing. 
BRONATE® can be applied in tank mixture with many other herbicides and insecticides registered for use on approved crops. Refer to 
the specific crop section for rate and other restrictions. To apply BRONATE® in mixture with another product, fill the spray tank 1/2 to 
3/4 full with clean water and begin agitation. If tank mixing with wettable powder, soluble powder, flowable or dry flowable products, add 
the powder or flowable product first. After the other herbicide is thoroughly mixed with water add the recommended amount of 
BRONATE® and add water to the spray tank to the desired level. If tank mixing with other product types, add the BRONATE® first 
before adding the other product. Always mix one product in water thoroughly before adding another product or compatibility problems 
may occur. Never mix two products together without first mixing in water. 
Maintain sufficient agitation while mixing and during application to ensure a uniform spray mixture. If spray mixture is allowed to remain 
without agitation for short periods of time, be sure to agitate until uniformly mixed before application. 
If tank mixing with products other than those listed within each crop section, a compatibility test is recommended to ensure satisfactory 
spray preparation. To test for compatibility, use a small container and mix a small amount (0.5 to 1 quart) of spray, combining all 
ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop, do not use this mixture for 
spraying. Indications of incompatibility usually will appear within 5 to 15 minutes after mixing. To ensure maximum crop safety and 
weed control, follow all cautions and limitations on this label and the labels of products used in the tank mixture with BRONATE® . 
SPRAYABLE LIQUID FERTILIZERS AND SPRAY ADDITIVES 
BRONATE® can be applied in combination with sprayable liquid fertilizer or spray additives such as surfactants or crop oil concentrate. 
When tank mixing with liquid fertilizer always add the fertilizer to the spray tank first and agitate thoroughly before adding BRONATE®. 
Always predetermine the compatibility with liquid fertilizer by mixing small proportional quantities in advance. Agitation must be 
maintained during filling and application operations to ensure that BRONATE® is evenly mixed with the fertilizer. Leaf bum may occur 
when BRONATE® is applied with liquid fertilizer, but new leaves are not adversely affected. 
CAUTION: Fertilizers and spray additives can increase foliage leaf bum when applied with BRONATE®. Do not apply fertilizers or 
spray additives with BRONATE® if leaf burn is a major concern due to environmental conditions, crop or variety sensitivity to 
BRONAT~. 
APPLICATION PROCEDURES 
BRONATE® can be applied to registered use areas by ground, aerial and sprinkler irrigation equipment. 
GROUND APPLICATION 
Use a standard herbicide boom sprayer that provides uniform and accurate application. Sprayer should be equipped with screens no 
finer than 50 mesh in the nozzle tips and in-line strainers. 
Select a spray volume and delivery system that will ensure thorough and uniform spray coverage. For optimum spray distribution and 
thorough coverage use of flat fan nozzles (maximum tip size 8008) with a spray pressure of 40-60 psi are recommended. Other nozzle 
types and lower spray pressures that produce coarse spray droplets may not provide adequate coverage of the weeds to ensure 
optimum control. Raindrop® nozzles and flood nozzles are not recommended as weed control with BRONATE® may be reduced. 
In general, a spray volume of 10 to 20 gallons per acre (GPA) is recommended for optimum spray coverage. A minimum of 5 GPA with 
a minimum spray pressure of 50 psi and a maximum ground speed of 10 mph may be used with higher speed, low volume ground 
application if ground terrain, crop and weed density allow effective spray distribution. When using higher speed equipment, a maximum 
ground speed of 10 mph is suggested if field conditions cause excessive boom movement during application which results in poor spray 
coverage. Ground applications made when dry, dusty field conditions exist may provide reduced weed control in wheel track areas. 
Applications using less than 10 gallons per acre may result in reduced weed control. 
When weed infestations are heavy, use of higher spray volumes and spray pressure will be helpful in obtaining uniform weed coverage. 
When com or grain sorghum are large enough to interfere with the spray pattern, drop nozzles shOUld be used to obtain uniform weed 
coverage. If you are unsure of the infestation level or size of crop, consult your local extension service. 
Do not apply when winds are gusty or when other conditions favor poor spray coverage and/or off target spray movement. 
Do not apply with nozzle height greater than 4 feet above crop canopy. 
AERIAL APPLICATION 
Use orifice discs, cores and nozzle types and arrangements that will provide for optimum spray distribution and maximum coverage. In 
general a minimum spray volume of 5 GPA and a maximum pressure of 40 psi are recommended. A minimum spray volume of 3 
gallons per acre may be used if crop canopy and weed density allow adequate spray coverage. Aerial applications using less than 5 
gallons of spray volume per acre may result in reduced weed control. 
Do not apply during inversion conditions, when winds are gusty or when other conditions favor poor spray coverage and/or off target 
spray movement. Off target spray movement can be minimized by increasing the spray volume per acre and not applying when winds 
exceed 10 mph.

SPRINKLER IRRIGATION APPLICATION 
BRONATE® Herbicide can be applied through sprinkler irrigation systems to wheat, barley, oats, rye and grasses grown for seed or sod 
production. 
Apply BRONATE® Herbicide through sprinkler systems including center pivot, lateral move, side (wheel) roll, solid set or hand move 
irrigation systems only. If hand moved piPe iS,used for chemigation, the pipe must not be handled in ,any way until 24 hours after 
chemigation has been completed and .,residues have.:been flushed from·the system. , When applying bYichemigation, no person may 
enter the application site unless in an enclosed vehicle. Do not apply this product through any other type of irrigation system. 
SPECIFIC REQUIREMENTS FOR APPLICATION THROUGH AUTOMATED, SPRINKL::ER IRRIGATION SYSTEM 
1.' The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the 
irrigation pipeline to prevent water source contamination from backflow. 
2. . The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back 
toward the injection pump. ' 
3. The pesticide injection pipeline m~st also contain a functional, normally closed, solenoid-operated valve located on the intake side 
'of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the 
" irrigation:system is either automatically or manually shut down. 
4. ,The system must contain functionaliriterlocking cOntrols to automatically shut off the, pesticide injection pump when the water 
"pump motor stops. 
5." The irrigation'line or water pump must include a functional pressure switch which will stop the water pump motor when the water 
pressure decreases to the point where pesticide distribution is adversely affected. 
6: Systems'mustuse a metering pump; such asa positive displacement injection pump (e.g., diaphragm pump) effectively designed 
and constructed of materials that,are·compatible with pestiCides and· capable of being fitted with a system interlock. 
7. Do not apply when wind speed favors drift beyond the area intended for treatment. 
8. Agitation is recommended in the' pesticide supply tank when applying the BRONATE® Herbicide. 
9. BRONATE® Hei"bicide should be appliedcOritiniJously for the duration6f the water application with center pivot and continuous 
lateral move systems. Application;'of BRONATE® Herbicide should be made during the last 30-45 minutes of the irrigation set 
with other overhead sprinkler systems. 
10. For best performance, set the sprinkler system to deliver approximately 0.5 inch or less of water per acre. 
11, Remove scale. pesticide residues and other foreign matter from the supply tank and entire injector system. Flush with clean 
water. 
12. If BRONATE® Herbicide is dilutedintne supply tank, fill the tank with half of the water amoilnt desired. add the BRONATE® and 
then add remaining water amount with agitation. Always dilute with at least 4 parts water to 1 part BRONAT~. 
13: Start the sprinklers and then injectBRONAT~ Herbicide into the irrigation line. BRONATE® should be injected with a positive 
.' displacement 'pump into the main' line at least ,8 feet ahead of, a right angle turn to insl:lre adequate mixing. Refer to the 
BRONATE® Herbicide label for detailed information on application rates and timings. 
CHEMIGATION USER PRECAUTIONS 
Application of more than 0.5 inch/acre of-irrigation water may result in decreased product performance on certain soils, 
Do not apply when 'cOnditions favor drift, wtlen systehl connections or fittings leak. or when nozzles"'do not provide uniform distribution. 
'Allow sufficierit"time for pesticide to beflusheCl through all the lines and nozzles before turnihg off irrigation water. 
Crop injury. lack of effectiveness. or illegal pesticide residues in the crop can result from non-uniform distribution of treated water. 
bo not connect ~n irrigation system u'sed. for,pesticide application to a public water system. 
If. you have questions about calibratio.n. you should contact State Extension Service specialists. equipment manufacturers or other 
experts. 
A person knowledgeable of the chemigation system ~nd responsible for its operations. or under the supervision of the responsible 
person. shali shut the system down and make· necessary adjustments should the need arise.

SPRAY DRIFT 
SENSITIVE AREAS: The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g., residential 
areas, bodies of water, known habitats for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blowing 
away from the sensitive areas). 
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related 
factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when 
making decisions. 
The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural 
field crops. These requirements do not apply to forestry applications, public health uses or to applications using dry formulation. 
1. The distance of the outer most nozzles on the boom must not exceed % the length of the wingspan or rotor. 
2. ~ozzles 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 should be observed. The applicator should be familiar with and take into account 
the information covered in the Aerial Drift Reduction Advisory Information. 
INFORMATION ON DROPLET SIZE: (This section is advisory in nature and does not supersede the mandatory label requirements) 
The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest 
droplets that provide sufficient coverage and control. 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 below). 
CONTROLLING DROPLET SIZE: (This section is advisory in nature and does not supersede the mandatory label reqUirements) 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger 
droplets. 
• Pressure - 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. 
• Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. 
• Nozzle Orientation - Orienting nozzles s6 that the spray is released parallel to the airstream produces larger droplets than other 
orientations and is the recommended practice. Significant deflection from horizontal will reduce droplet size and increase drift 
potential. 
• 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. Solid stream nozzles oriented straight back produce the largest droplets 
. and the lowest drift. 
BOOM LENGTH: (This section is advisory in nature and does not supersede the mandatory label requirements) 
For some use patterns, reducing the effective boom length to less than % of the wingspan or rotor length may further reduce drift 
without redUCing swath width. 
APPLICATION HEIGHT: (This section is advisory in nature and does not supersede the mandatory label requirements) 
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: (This section is advisory in nature and does not supersede the mandatory label requirements) 
When applications are made with a crosswind, 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: (This section is advisory in nature and does not supersede the mandatory label requirements) 
Drift potential is lowest between wind speeds of 2 - 10 mph. However, many factors, including droplet size and equipment type 
determine drift potential at any given speed. Application should be avoided 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 spray drift. 
TEMPERATURE AND HUMIDITY: (This section is advisory in nature and does not supersede the mandatory label reqUirements) 
When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet 
evaporation is most severe when conditions are both hot and dry. 
TEMPERATURE INVERSIONS: (This section is advisory in nature and does not supersede the mandatory label requirements) 
Applications should not occur during a 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 concentrated 
cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical 
air mixing.
