ENGINEERING CONTROLS STATEMENT 
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker 
Protection Standard (WPS) for agricultural pesticides [(40 CFR 170.240(d)(4-6)], the handler PPE requirements may be reduced 
or modified as specified in the WPS. 
 
ENVIRONMENTAL HAZARDS
Do not apply directly to water or to areas where surface water is present. Do not apply to intertidal areas below the mean hig h 
water mark. Do not contaminate water by cleaning of equipment or disposal of equipment washwaters or rinsate. 
 
This pesticide is toxic to vascular plants and must 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, Glufosinate 280 SL 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 til l and contour plowing; these methods also reduce pesticide run- off. 
Use of vegetation filter strips along rivers, creeks, streams, wetlands, etc. or on the downhill side of fields where run-off could occur 
to minimize water run-off is recommended. 
DIRECTIONS FOR USE
It is a violation of Federal law to use Glufosinate 280 SL in a manner inconsistent with its labeling. 
 
Do not use Glufosinate 280 SL until you have read the entire la bel. Do not apply Glufosinate 280 SL in a way that will contac t 
workers or other persons, eit her directly or through drift. Onl y protected handlers may be in the area during application. For any 
requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation. 
In the State of New York Only: Not For Use In Nassau and Suffolk Counties.

IMPORTANT CROP SAFETY INFORMATION 
READ BEFORE USING GLUFOSINATE 280 SL 
BURNDOWN TREATMENTS
Glufosinate 280 SL may be applied as a burndown treatment prior to planting or prior to crop emergenceof any canola, sweet 
corn[1], corn, cotton, olive, soybean or sugar beet. 
POST EMERGENT TREATMENTS 
Post emergence row crop applications of Glufosinate 280 SL may b e made only to crops containing the LibertyLink trait. The 
basis of selectivity of Glufosinate 280 SL in crops is the pres ence of a gene in LibertyLink cr ops which results in a plant th at is 
not sensitive to the active ingredient of Glufosinate 280 SL. Tank mixtures of Glufosinate 280 SL with other products may impact 
crop safety and increase risk of crop injury. 
Many seed trade names are available under the LibertyLink trait , contact the seed manufactu rer or seed distributor to 
determine if the seed variety is designated and supported to be LibertyLink. 
Crops not containing the LibertyLink gene will be sensitive to Glufosinate 280 SL and severe crop injury and/or death 
may occur. Do not allow spray to contact foliage or green tissu e of desirable vegetation unless the crop contains the 
LibertyLink trait. 
 
Post emergent applications of Glufosinate 280 SL may be applied to cotton not containing the LibertyLink trait using a hooded 
sprayer. 
TREE, NUT, VINE AND BERRY TREATMENTS 
Applications to trees, vines and berries must avoid contact of Glufosinate 280 SL solution, spray drift or mist with green bark , 
stems or foliage as injury may occur to trees, berries and vine s. Only trunks with callused mature brown bark may be sprayed 
unless protected from spray contact by nonporous wraps, grow tu bes or waxed containers. Contact of Glufosinate 280 SL with 
parts of trees, berries or vines other than mature brown bark can result in serious damage.
[1 – Not for use in California] 
NON-AGRICULTURAL USE REQUIREMENTS
The requirements in this box apply to uses of this product that are NOT within the scope of the Worker Protection Standard for 
agricultural pesticides (40 CFR Part 170). The WPS applies when this product is used to produce agricultural plants on farms,
forests, or greenhouses.
Do not enter or allow others to enter treated areas until sprays have dried.

PRODUCT INFORMATION
Glufosinate 280 SL is a water-sol uble herbicide for application as a foliar spray for the control of a broad spectrum of emerge d 
annual and perennial grass and broadleaf weeds in a variety of crops. Glufosinate 280 SL is registered for use as a: 
x burndown treatment prior to planti ng or prior to emergence of c anola, corn, cotton, sweet corn, olive, soybean and sugar 
beets 
x post emergence weed control herbicide to be applied on crops containing LibertyLink trait 
x post emergence weed control in cotton when applied with a hooded sprayer in-crop 
x post emergence weed control in listed tree, olives, vine, and berry crops 
x applied for potato vine desiccation. 
 
Many seed trade names are available under the LibertyLink trait , contact the seed manufacturer or seed distributor to 
determine if the seed variety is designated and supported as containing the LibertyLink trait. 
It is important to always follow a responsible integrated weed management program. Contact your local agronomic advisor for 
more specific information on integrated weed management in your area. 
 
Glufosinate 280 SL is only foliar-active with little or no activity in soil. Weeds that emerge after application will not be controlled. 
 
Apply Glufosinate 280 SL to act ively growing weeds as described in the WEED CONTROL FOR ROW CROPS section to get 
maximum weed control. Uniform, thorough spray coverage is neces sary to achieve consistent weed control. Necrosis of leaves 
and young shoots occur within 2 to 4 days after application under good growing conditions. 
x Glufosinate 280 SL is rainfast 4 hours after application to mos t w e e d s p e c i e s ; t h e r e f o r e , r a i n f a l l w i t h i n 4 h o u r s m a y 
necessitate retreatment or may result in reduced weed control. 
x Make applications between dawn and 2 hours before sunset to avoid the possibility of reduced lambsquarters and velvetleaf 
control. 
x Consult your local Cooperative Extension Service or Winfield Solutions, LLC representative for guidelines on the optimum 
application timing for Glufosinate 280 SL in your region. 
x Weed control may be reduced if application is made when heavy d ew, 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. 
x To maximize weed control, do not cultivate from 5 days before an application to 7 days after an application.

WEED RESISTANCE MANAGEMENT
For resistance management, Glufosinate 280 SL contains a Group 10 herbicide – Glufosinate-ammonium. Any weed population 
may contain or develop plants naturally resistant to Glufosinate 280 SL and other Group 10 herbicides. The resistant biotypes may 
dominate the weed population if these herbicides are used repeat edly in the same field. Appropriate resistance management 
strategies should be followed. 
 
When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed
species in the same field, naturally-occurring resistant biotyp es may survive a correctly applied herbicide treatment, propaga te, 
and become dominant in that field. Adequate control of these re sistant weed biotypes cannot be expected. If weed control is 
unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action. 
 
To delay herbicide resistance, take one or more of the following steps: 
x Rotate the use of Glufosinate 280 SL or other Group 10 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.

5 
 
x Adopt an integrated weed-management program for herbicide use t hat includes scouting and uses historical information 
related to herbicide use and crop rotation, and that considers tillage (or other mechanical contr ol 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 Fields should be scouted prior to application to identify the weed species present and their growth stage to determine if the 
intended application will be effective. 
x Scout after herbicide applicati on to monitor weed populations f or early signs of resistance development. Indicators of 
possible herbicide resistance include: 
1) Failure to control a weed species normally controlled by the he rbicide at the dose applied, especially if control is 
achieved on adjacent weeds; 
2) A spreading patch of non-controlled plants of a particular weed species; 
3) 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. Prev ent 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 recomme ndations for specific crops and resistant weed 
biotypes. 
x For further information or to report suspected resistance, contact your Winfield Solutions, LLC representative.
It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread a nd 
dispersal of resistant biotypes. Contact your local sales repre sentative, crop advisor, or extension agent to find out if susp ected 
resistant weeds to this MOA have been found in your region. 
 
INTEGRATED PEST MANAGEMENT 
Winfield Solutions, LLC recommends the use of Integrated Pest Ma nagement (IPM) programs to control pests. This product may 
be used as part of an Integrated Pest Management (IPM) program which can include biological, cultural, and genetic practices 
aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including
field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest 
populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants 
or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop or s ite 
systems in your area. 
 
WEED CONTROL FOR ROW CROPS
Rates in fluid ounce of formulated product per acre for the con trol of weeds as shown in the weed control tables. In weed 
populations with mixed species, apply at a rate needed for the species targeting less than three-inch weeds.

Application and Mixing Restrictions: 
x Do not use flood jet nozzles, controlled droplet application equipment, or air-assisted spray equipment. 
x Do not apply when winds are gusty, or when conditions will favor movement of spray particles off the desired spray 
target. 
 
Compatibility Testing: 
If Glufosinate 280 SL is to be mixed with other pesticides, test the compatibility of the intended tank mixture prior to mixing the 
products in the spray tank. The following procedure assumes a s pray volume of 25.0 gallons per a cre. 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 1.0 quart jar. 
2. For each pound of a dry tank mix partner to be applied per ac re, add 1.5 teaspoons to the jar. 
3. For each 16.0 fluid ounces of a liquid tank mix partner to be applied per acre, add 0.5 teaspoon to the jar. 
4. For each 16.0 fluid ounces of Glufosinate 280 SL 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 Instructions: Glufosinate 280 SL may be applied in tank mix combinations with other products provided these other 
products are labeled for the timing and method of application f or the crop to be treated. The ta nk mix partner must be used in
accordance with the label limitations and precautions. No label dosage rates may be exceeded. Glufosinate 280 SL cannot be 
mixed with any product containi ng a label prohibi tion against such mixing. Refer to the specific crop section for rates and ot her 
restrictions. 
 
It is the pesticide user's responsibility to ensure that all products are registered for the intended use. Read and follow the applicable 
restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive 
directions for use and precautionary statements of each product in the tank mixture.
 
Glufosinate 280 SL must be applied with properly calibrated and clean equipment. Glufosinate 280 SL is formulated to mix readily 
in water. 
 
Prior to adding Glufosinate 280 SL 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 SL with water to make a finished spray solution as follows: 
1. Properly calibrated and clean equipment 
2. Fill the spray tank half full with water. 
3. Start agitation. 
4. 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. 
5. Add the appropriate amount of ammonium sulfate (AMS) to the spray tank. 
6. If mixing with a liquid tank mix partner, add the liquid mix partner next. 
7. Complete filling the spray tank with water before adding Glufosinate 280 SL, as foaming may occur. 
8. Add the proper amount of Glufosinate 280 SL and continue agitation. 
9. 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. 
 
If tank mix partners 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 SL, thoroughly clean bulk storage tank, refillable tank, nurse tanks, spray tank, lines, and filt er, 
particularly if a herbicide with the potential to injure crops w as previously used. Thoroughly rinse equipment using a commerci al 
tank cleaner and as instructed on the prior herbicide label. 
 
After using Glufosinate 280 SL, triple rinse the spray equipmen t and clean with a commercial tank cleaner before using the 
equipment for crops not containing LibertyLink trait . Make sure any rinsate or foam is thoroughly removed from spra y 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. 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. 
 
MANDATORY SPRAY DRIFT MITIGATION
x When applying to crops via aerial application equipment, the sp ray boom must be mounted on the aircraft so as to 
minimize drift caused by wing tip or rotor blade vortices. The boom length must not exceed 75% of the wingspan or 90% 
of the rotor blade diameter.
x When applying to crops via aerial application equipment, applic ators must use ½ swath displacement upwind at the 
downwind edge of the field.
x Do not apply when wind speeds exceed 10 miles per hour at the application site. 
x Do not apply during temperature inversions. 
x For aerial applications, do not release spray at a height great er than 10 ft above the crop canopy, unless a greater 
application height is necessary for pilot safety.
x For ground applications and aerial applications, select nozzle and pressure that deliver medium to coarse spray droplets 
as indicated in nozzle manufacturer’s catalogues and in accordance with ASABE Standard 572.1.
x Spray at the appropriate boom height based on nozzle selection and nozzle spacing, but do not exceed a boom height 
of 24 inches above target pest or crop canopy. Set boom to lowe st effective height over the target pest or crop canopy 
based on equipment manufacturer’s directions. Automated boom height controllers are recommended with large booms 
to better maintain optimum nozzle to canopy height. Excessive boom height will increase the potential for spray drift.
x For non-crop vegetation management ground applications, apply w ith the nozzle height no more than 4 feet above the
ground or target vegetation, unless necessitated by the applica tion equipment. Examples would include roadside, 
railroad, utility rights of way, forestry and other industrial vegetation management applications where safety or natural 
barriers obstruct application.
SPRAY DRIFT ADVISORIES 
The interaction of many equipment and weather-related factors d etermines the potential for spray drift. The applicator is 
responsible for considering all these factors when making application decisions. 
 
POLLINATOR ADVISORY STATEMENT 
This product contains a herbicide. Follow all label directions and precautions to minimize potential off-target exposure in or der to 
prevent effects to non-target plants adjacent to the treated site which may serve as habitat or forage for pollinators. 
IMPORTANCE OF 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. The presence of sensitive species nearby, the environmental conditions, and 
pest pressure may affect how an applicator balances drift contr ol 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 – Ground Boom 
x Volume - Use high flow rate nozzles to apply the highest practic al spray volume. Nozzles with higher rated flows produce 
larger droplets. 
x Pressure - Use the lower spray pressures recommended for the 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 intende d application. With most nozzle types, narrower spray 
angles produce larger droplets. Consider using low-drift nozzles. 
 
Controlling Droplet Size – Aircraft 
x Number of Nozzles - Use the minimum number of nozzles with the highest flow rate that provide uniform coverage. 
x Nozzle Orientation - Orienting nozzles so that the spray is emitt ed backwards, parallel to the ai rstream will produce larger 
droplets than other orientations. AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. 
x Nozzle Type - Solid stream nozzles (such as disc and core with s wirl plate removed) oriented straight back produce larger 
droplets than other nozzle types. 
x Boom Length - Longer booms increase drift potential. Therefore, a shorter boom length is recommended. 
x Application Height - Application more than 10 ft. above the canopy increases the potential for spray drift.

11 
 
 
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 (du e to inversion potential) or more than 10 mph. However, many 
factors, including droplet size and equipment type determine dr ift potential at any given wind speed. AVOID APPLICATIONS 
DURING GUSTY OR WINDLESS CONDITIONS. 
Note: Local terrain can influence wind patterns. Every applicator needs to be familiar be familiar with local wind patterns and how 
they affect 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. Tempera t u r e i n v e r s i o n s r e s t r i c t v e r t i c a l a i r m i x i n g , w h i c h c a u s e s s m a ll 
suspended droplets to remain close to the ground and move later ally 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 moveme nt 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. 
 
APPLICATION DIRECTIONS FOR BURNDOWN USE 
Glufosinate 280 SL may be applied as a burndown treatment prior to planting or prior to emergence of any variety of canola, 
corn, sweet corn[1], cotton, soybean or sugar beet. [1 – Not for use in California] 
Application Timing: 
x Apply to small and actively growing weeds, targeting less than 3-inch weeds in height. For additional information refer to 
the WEED CONTROL FOR ROW CROPS section. 
x Warm temperatures, high humidity, and bright sunlight improve the performance of Glufosinate 280 SL. 
x Weed control may be reduced when applications are made to weeds under stress due to drought or cool temperatures. 
x For optimum results on lambsquarters, Palmer amaranth and velve tleaf make applications between dawn and 2 hours 
before sunset. 
x Glufosinate 280 SL is rainfast 4 hours after application, therefore, rainfall within 4 hours may necessitate retreatment. 
Application Rates: 
x Apply 29.0 – 43.0 fluid ounces per acre of Glufosinate 280 SL depending on crop, weed species and intention of post 
application use. Please see application charts below. 
Adjuvant: 
x Ammonium sulfate (AMS) may be used at 1.5 to 3 pounds per acre. Adjuvant rates are dependent on tank mix partners, 
temperatures, environmental conditions and potential for leaf burn. 
x AMS has shown to improve weed control of difficult-to-control w eeds, like lambsquarters and velvetleaf, under difficult 
environmental conditions (low relative humidity) or hard water. 
 
Surfactants / Crop Oils: 
x The use of surfactants may be included. Please refer to the surfactant label for more detailed information.

Hooded Sprayer Application Instructions: 
Application of Glufosinate 280 SL to cotton varieties not containing the LibertyLink trait 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 cr op 
from the spray solution. This equipment must be set up and oper ated 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 es cape and come into contact with the cotton, causing damage or 
destruction of the crop. 
 
Herbicide rates and spray volume instructions 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: 
Bandwidth in inches
 X Broadcast RATE per acre = Amount of banded product needed per acre
Row width in inches
Band width in inches
 X Broadcast spray VOLUME per acre = Banded spray volume needed per acre
Row width in inches
 
Post-Harvest – Fall Burndown: 
Glufosinate 280 SL may be applied as a post-harvest burndown treatment to fields (after cotton harvest). Up to 43.0 fluid ounce s 
per acre (0.79 lb ai/A) of Glufosinate 280 SL may be applied in a single application to control larger weeds growing in the cro p at 
the time of harvest. If more than 29.0 fluid ounces per acre (0 .53 lb ai/A) is used in a single application, the annual total m ay not 
exceed 72.0 fluid ounces per acre (1.32 lb ai/A), including all application timings. Refer to the ROTATIONAL CROP 
RESTRICTIONS section of this label for appropriate rotational crop information.
