Glufosinate 280 [Alt. Brand Name] may be applied as a burndown treatment prior to planting or prior to 
emergence of any conventional variety of sweet corn or cotton. Glufosinate 280 [Alt. Brand Name] may be 
applied to conventional cotton not tolerant to the active ingredient in Glufosinate 280 [Alt. Brand Name] 
using a hooded sprayer. 
Applications to trees, vines and berries should avoid contact of Glufosinate 280 [Alt. Brand Name] 
solution, spray, drift or mist with green bark, stems, or foliage, as injury may occur to trees, berries and 
vines. Only trunks with callused, mature brown bark should be sprayed unless protected from spray contact 
by nonporous wraps, grow tubes or waxed containers. Contact of Glufosinate 280 [Alt. Brand Name] with 
parts of trees, berries or vines other than mature brown bark can result in serious damage. 
PRODUCT INFORMATION
Glufosinate 280 Herbicide [Alt. Brand Name] is a water-soluble herbicide for application as a foliar spray for 
the control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds in trees, vines 
and berries. Glufosinate 280 Herbicide [Alt. Brand Name] may also be applied for potato vine desiccation. 
Glufosinate 280 Herbicide [Alt. Brand Name] may also be applied as a broadcast burndown application 
before planting or prior to emergence of any conventional variety of sweet corn or cotton.
Glufosinate 280 Herbicide [Alt. Brand Name] is only foliar-active with little or no activity in soil. Weeds that 
emerge after application will not be controlled. Apply Glufosinate 280 Herbicide [Alt. Brand Name] to actively 
growing weeds as described in the Weed Control Recommendations for Row Crops section to get maximum

weed control. Uniform, thorough spray coverage is necessary to achieve consistent weed control. Necrosis 
of leaves and young shoots occur within 2 to 4 days after application under good growing conditions. 
•Glufosinate 280 Herbicide [Alt. Brand Name] is rainfast four (4) hours after application to most weed 
species; therefore, rainfall within four (4) hours may necessitate retreatment or may result in reduced weed 
control. 
•Applications should be made between dawn and 2 hours before sunset to avoid the possibility of reduced
lambsquarters and velvetleaf control. 
•Weed control may be reduced if application is made when heavy dew, fog and mist/rain are present; or 
when weeds are under stress due to environmental conditions such as drought, cool temperatures or 
extended periods of cloudiness. 
•To maximize weed control, do not cultivate from 5 days before an application to 7 days after an application.

Integrated Weed Management
The active ingredient in Glufosinate 280 Herbicide [Alt. Brand Name] is glufosinate-ammonium, which is a 
glutamine synthetase inhibitor (Group 10). Integrated weed management guidelines promote an 
economically viable, environmentally sustainable and socially acceptable weed control program regardless 
of the herbicide(s) used. The highlights of a successful integrated weed management program include:
1. Correctly identify weeds and look for trouble areas within field to identify resistance indicators.
2. Rotate crops.
3. Start the growing season with clean fields.
4. Rotate herbicide modes of action by using multiple modes of action during the growing season and 
apply no more than two applications of a single herbicide mode of action to the same field in a two-
year period. One method to accomplish this is to rotate herbicide tolerant trait systems.
5. Apply listed rates of herbicides to actively growing weeds at the correct time with the right 
application techniques.
6. Control any weeds that may have escaped the herbicide application.
7. Thoroughly clean field equipment between fields.
Contact your local agronomic advisor for more specific information on integrated weed management for your 
area.

APPLICATION AND MIXING PROCEDURES
Ground Application : Glufosinate 280 Herbicide [Alt. Brand Name] should be applied broadcast in a 
minimum of 15 gallons of water per acre. Under dense weed/crop canopies, 20 to 40 gallons of water per 
acre should be used so that thorough spray coverage will be obtained. Apply Glufosinate 280 Herbicide [Alt. 
Brand Name] using nozzles and pressures that generate MEDIUM (about 250 to 350 microns) spray 
droplets category as reported by the nozzle manufacturer and in accordance to ASABE S 572. Do not use 
nozzles and pressures that result in COARSE sprays. FINE sprays should also be avoided to minimize 
spray drift risk. Boom height should be based on nozzle manufacturer recommendations. See the Spray Drift 
Management section of this label for additional information on proper application of Glufosinate 280
Herbicide.

Page 7 of 18
page 7 of 18
Aerial Application : Poor coverage will result in reduced weed control. For optimal weed control, apply 
Glufosinate 280 Herbicide [Alt. Brand Name] in a minimum of 10 gallons per acre. Apply Glufosinate 280 
Herbicide [Alt. Brand Name] using nozzles and pressures that generate MEDIUM (about 300 to 400 
microns) spray droplets category as reported by the nozzle manufacturer and in accordance to ASABE 
S 572 based upon the selected air speed. Do not use nozzles and pressures that result in COARSE sprays. 
FINE sprays should also be avoided to minimize spray drift risk. See the Spray Drift Management section of 
this label for additional information on proper application of Glufosinate 280 Herbicide.
COMPATIBILITY TESTING
If Glufosinate 280 Herbicide [Alt. Brand Name] is to be mixed with pesticide products not listed on this label, 
test the compatibility of the intended tank mixture prior to mixing the products in the spray tank. The 
following procedure assumes a spray volume of 25 gallons per acre. For other spray volumes, adjust the 
amount of the water used accordingly. Check compatibility as follows: 
1. Place 1.0 pint of water from the source that will be used to prepare the spray solution in a clear 1-
quart jar. 
2. For each pound of a dry tank mix partner to be applied per acre, add 1.5 teaspoons to the jar. 
3. For each 16 fl oz of a liquid tank mix partner to be applied per acre, add 0.5 teaspoon to the jar. 
4. For each 16 fl oz of Glufosinate 280 Herbicide to be applied per acre, add 0.5 teaspoon to the jar. 
5. After adding all the ingredients, place a lid on the jar and tighten. Invert 10 times to mix. 
6. Let the mixture stand for 15 minutes, and evaluate the solution for uniformity and stability. Look for 
separation, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. 
If the tank mix partners are not compatible, do not use the mixture in a spray tank. 
7. After compatibility testing is complete, dispose of any pesticide wastes in accordance with the 
Storage and Disposal section of this label. 
MIXING INSTRUCTIONS
Tank Mix : Glufosinate 280 Herbicide [Alt. Brand Name] may be applied in tank mix combinations with 
labeled rates of other products provided these other products are labeled for the timing and method of 
application for the crop to be treated. The tank mix partner must be used in accordance with the label 
limitations and precautions. No label dosage rates may be exceeded. Glufosinate 280 Herbicide [Alt. Brand 
Name] cannot be mixed with any product containing a label prohibition against such mixing. Refer to the 
specific crop section for rate recommendations and other restrictions. 
Glufosinate 280 Herbicide [Alt. Brand Name] must be applied with properly calibrated and clean equipment. 
Glufosinate 280 Herbicide [Alt. Brand Name] is formulated to mix readily in water. Prior to adding 
Glufosinate 280 Herbicide [Alt. Brand Name] to the spray tank, ensure that the spray tank is thoroughly 
clean, particularly if a herbicide with the potential to injure crops was previously used (see Cleaning 
Instructions). 
Mix Glufosinate 280 Herbicide [Alt. Brand Name] with water to make a finished spray solution as follows: 
1. Fill the spray tank half full with water. 
2. Start agitation. 
3. If mixing with a flowable/wettable powder tank mix partner. Prepare a slurry of the proper amount of 
the product in a small amount of water. Add the slurry to the spray tank. 
4. Add the appropriate amount of ammonium sulfate (AMS) to the spray tank. 
5. If mixing with a liquid tank mix partner, add the liquid mix partner next. 
6. Complete filling the spray tank with water. 
7. Add the proper amount of Glufosinate 280 Herbicide [Alt. Brand Name] and continue agitation. 
8. If foaming occurs, use a silicone-based antifoam agent. 
Ensure that all spray system lines including pipes, booms, etc. have the correct concentration of spray 
solution by flushing out the spray system lines before starting the crop application.

Page 8 of 18
page 8 of 18
If tank mix partners recommended on this label are added, maintain good agitation at all times until contents 
of the tank are sprayed. If the spray mixture is allowed to settle, thorough agitation is required to resuspend 
the mixture before spraying is resumed. Keep bypass line on or near bottom of tank to minimize foaming. 
Screen size in nozzles or line strainers must be 50 mesh or larger. 
CLEANING INSTRUCTIONS
Before using Glufosinate 280 Herbicide, thoroughly clean bulk storage tank, refillable tank, nurse tanks, 
spray tank, lines, and filter, particularly if a herbicide with the potential to injure crops was previously used. 
Equipment should be thoroughly rinsed using a commercial tank cleaner. 
After using Glufosinate 280 Herbicide , triple rinse the spray equipment and clean with a commercial tank 
cleaner before using for crops not labeled LibertyLink. Make sure any rinsate or foam is thoroughly removed 
from spray tank and boom. Rinsate may be disposed following the pesticide disposal directions on this label. 
SPRAY DRIFT MANAGEMENT
Spray drift may result in injury to non target crops or vegetation. To avoid spray drift, do not apply when wind 
speed is greater than 10 MPH or during periods of temperature inversions. Do not apply when weather 
conditions, wind speed, or wind direction may cause spray drift to non-target areas. AVOIDING SPRAY 
DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR. 
x All aerial and ground application equipment must be properly maintained and calibrated using 
appropriate carriers. 
x For all non-aerial applications, wind speed must be measured adjacent to the application site, on the 
upwind side, immediately prior to application. 
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). 
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. 
Aerial Drift Management: The following drift management requirements must be followed to avoid off-target 
drift movement from aerial applications to agricultural field crops. 
1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan 
or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards 
more than 45 degrees. 
Where states have more stringent regulations, they should be observed. The applicator should be familiar 
with and take into account the information covered in the Aerial Drift Reduction Advisory Information. 
AERIAL DRIFT REDUCTION ADVISORY INFORMATION
Information on Droplet Size: 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 on next page). AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE 
RESPONSIBILITY OF THE APPLICATOR. 
Controlling Droplet Size:
Volume: Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated 
flows produce larger droplets.

Page 9 of 18
page 9 of 18
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 so 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: For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan 
or rotor length may further reduce drift without reducing swath width. 
Application Height: Applications should not be made at a height greater than 10 feet above the top of the 
largest plants unless a greater height is required for aircraft safety. Making applications at the lowest height 
that is safe reduces exposure of droplets to evaporation and wind. 
Swath Adjustment: When applications are made with a crosswind, the swath will be displaced downward. 
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: 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. Applications should be avoided below 
2 miles per hour 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 : 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. Avoid spraying during conditions of low humidity and/or high temperatures. 
Temperature Inversions: Do not make aerial or ground applications into areas of temperature inversions. 
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. 
APPLICATION DIRECTIONS FOR BURNDOWN USE
Glufosinate 280 Herbicide [Alt. Brand Name] may be applied as a burndown treatment prior to planting or 
prior to emergence of any conventional variety of sweet corn or cotton. Apply a minimum of 29 fl oz/A of 
Glufosinate 280 Herbicide [Alt. Brand Name] for burndown of existing weeds just prior to planting or prior to 
emergence of sweet corn or cotton. For best results, apply to emerged, young, actively growing weeds. 
Warm temperatures, high humidity, and bright sunlight improve the performance of Glufosinate 280. Weed 
control may be reduced when applications are made to weeds under stress due to drought or cool 
temperatures. In cotton, if environmental conditions prevent timely application, a single application may be 
made of up to 43 fl oz/A of Glufosinate 280 Herbicide.

APPLICATION METHODS TO NON-LIBERTYLINK COTTON
Application of Glufosinate 280 Herbicide [Alt. Brand Name] to cotton varieties not labeled as LibertyLink 
requires the use of hooded spray equipment designed to minimize exposure of the spray to the cotton stand. 
A hooded sprayer directs the spray onto weeds, while shielding the cotton stand from contact. Use nozzles 
that provide uniform coverage within the treated area. Keep hoods on these sprayers adjusted to protect 
desirable vegetation. Extreme care must be exercised to avoid exposure of the desirable vegetation to the 
spray. 
With a hooded sprayer, the spray pattern is completely enclosed on the top and all 4 sides by a hood, 
thereby shielding the crop from the spray solution. This equipment must be set up and operated in a manner 
that avoids bouncing or raising the hoods off the ground in any way. The spray hoods must be operated on 
the ground or skimming across the ground. Tractor speed must be adjusted to avoid bouncing of the spray 
hoods. Avoid operation on rough or sloping ground where the spray hoods might be raised off the ground. If 
the hoods are raised, spray particles may escape and come into contact with the cotton, causing damage or 
destruction of the crop. 
Herbicide rates and spray volumes are presented as broadcast equivalents and must be reduced in 
proportion to the area actually treated. Use the following formulas to calculate the correct rate and volume 
per planted (field) acre: 
Band width in inches X Broadcast RATE = Amount of banded product 
Row width in inches per acre needed per acre
Band width in inches X Broadcast VOLUME = Amount of banded product 
Row width in inches per acre needed per acre

POST-HARVEST
Glufosinate 280 Herbicide [Alt. Brand Name] may be applied as a post-harvest burndown treatment to fields 
(after cotton harvest). Up to 43 fl oz/A of Glufosinate 280 Herbicide [Alt. Brand Name] may be applied in a 
single application to control larger weeds growing in the crop at the time of harvest. 
If more than 29 fl oz/A is used in a single application, the seasonal total may not exceed 72 fl oz/A, including 
all application timings. Refer to the Rotational Crop Restrictions section of this label for appropriate rotational 
crop information.
