rant the use of this product on crops other than those 
designated as LibertyLink
® to safely withstand the 
application of Liberty 280 SL to the extent consistent 
with applicable law .
The basis of selectivity of Liberty 280 SL in crops is the 
presence of a gene in LibertyLink crops which results in 
a plant that is resistant to the active ingredient of 
 Liberty 280 SL . Crops not containing this gene will not 
be resistant to Liberty 280 SL and severe crop injury 
and/or death may occur . DO NOT allow spray to contact 
foliage or green tissue of desirable vegetation other than 
crops resistant to the active ingredient in this product .
 Liberty 280 SL may be applied to conventional or other 
transgenic cotton not resistant to the active ingredient in 
 Liberty 280 SL using a hooded sprayer .
Applications in bearing and nonbearing perennial 
fruit, nut, and berry crops, and hops must avoid 
contact of 
 Liberty 280 SL solution, spray, drift or mist 
with green bark, stems, or foliage, as injury may occur . 
Only spray trunks with callused, mature brown bark 
unless protected from spray contact by nonporous 
wraps, grow tubes or waxed containers . C ontact of 
 Liberty 280 SL with parts of trees, vines, berries, tropi -
cal or subtropical fruits other than mature brown bark 
can result in serious damage .

 section .
• L iberty 280 SL is a contact herbicide and requires uni -
form, thorough spray coverage .
• Warm temperatures, high humidity, and bright sunlight 
improve the performance of 
 Liberty 280 SL .
• Necrosis of leaves and young shoots occurs within 2 to 
4 days after application under good growing conditions .
• L iberty 280 SL 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 . R efer to specific use sections of 
this label for minimum intervals required before re- 
application of this product and use rates .

5
• L iberty ® 280 SL h erbicide requires sunlight for activity . 
Applications near dawn and dusk may result in reduced 
weed control . F or best results, make applications 
between sunrise and 2 hours before sunset .
• 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 
including drought, cool temperatures, or extended peri -
ods of cloudiness .
• To maximize weed control, DO NOT cultivate from 
5 days before an application to 7 days after an 
application .
• Consult your local Cooperative Extension Service or 
BASF representative for guidelines on the optimum appli -
cation timing for 
 Liberty 280 SL in your region .

section of the label .
*** Planting of cover crops for conservation purposes 
may be planted in fields previously treated with 
 Liberty 280 SL as long as these cover crops are not 
grazed by livestock nor harvested for food . F or best 
results, DO NOT plant cover crops less than 7 days 
after an application of Liberty 280 SL nor before 
1/2 inch of rainfall or irrigation has occurred . P lanting 
sooner than this may result in stand reduction . P lant-
ing of crops listed in the Rotational Crop 
Restrictions that follow the listed planting intervals 
and other restrictions are considered a rotational crop 
and therefore may be harvested .
Resistance Management
 Liberty 280 SL is a Group 10 herbicide, i .e ., a glutamine 
synthetase inhibitor . A g iven 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 . T he 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 resis-
tance, as no single strategy is likely to be totally effective .
Contact your local BASF representative, crop advisor or 
extension agent to find out if suspected resistant weeds to 
this MOA have been found in your region . I f resistant bi otypes 
of target weeds have been reported, use the application rates 
of this product specified for your local conditions . 
Fields should be scouted prior to application to identify the 
weed species present and the growth to determine if the 
intended application will be effective . Fie lds should be scout-
ed after application to verify that the treatment was effective .
Suspected herbicide-resistant weeds may be identified by 
these indicators:
• Failure to control a weed species normally controlled by 
the herbicide at the dose applied, especially if control is 
achieved on adjacent weeds;
• A spreading patch of non-controlled plants of a particular 
weed species; and
• Surviving plants mixed with controlled individuals of the 
same species .
Report an incidence of non-performance of this product 
against a particular weed species to your local extension spe-
cialists, certified crop advisor and/or BASF representative .
• Rotate crops - Crop rotation diversifies weed 
management .
• Rotate herbicide-resistant traits - Alternate 
 herbicide-resistant (HR) traits and/or use HR trait stacks 
for more efficient rotation .

6
• Use multiple herbicide sites of action - Use tank mix 
partners and multiple sites of action during both the 
growing season and from year to year to reduce the 
selection pressure of a single site of action .
• Know your weeds. Know your fields - Closely moni-
tor problematic areas with difficult-to-control weeds or 
dense weed populations .
• Start with clean fields - Effective tillage or the use of a 
burndown herbicide program can control emerged 
weeds prior to planting .
• Stay clean. Use residual herbicides - Regardless of 
tillage system, preemergence or early postemergence 
soil-applied residual herbicides should be used when 
possible .
• Apply herbicides correctly - Ensure proper applica-
tion, including timing, full use rates and appropriate spray 
volumes .
• Control weed escapes - Consider spot herbicide 
applications, row wicking, cultivation or hand removal of 
weeds or other techniques to stop weed seed produc-
tion and improve weed management .
• 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 pre -
vent major weed shifts .
• Clean equipment - Prevent the spread of herbicide- 
resistant weeds and their seeds .
• Manage borders. Prevent an influx of weeds into the 
field by managing borders .
• Scout fields.
• Diversified approach. To the extent possible, use a 
diversified approach towards weed management . Whe n-
ever possible, incorporate multiple weed-control 
practices including mechanical cultivation, biological 
management practices or crop rotation .
Contact your local extension specialist, certified crop advi -
sory and/or BASF representative for additional resistance 
management or IPM recommendation . Al so for more infor-
mation on weed resistance management, visit the 
Herbicide Resistance Action Committee (HRAC) on the 
web at http://www .hra cglobal .com .
Weeds Controlled
For best results, apply to emerged, young, actively grow-
ing weeds less than 3 inches in height . W arm 
temperatures, high humidity, and bright sunlight improve 
the performance of 
 Liberty® 280 SL h erbicide . Uniform, 
thorough spray coverage of weeds is necessary to achieve 
consistent weed control . R efer to the Application 
 Equipment section for more details .
Weed control may be reduced when applications are made 
to weeds under stress including drought or cool tempera-
tures and in dense populations . St ressed conditions may 
also include prior treatments of other contact or systemic 
herbicides . R egrowth of weeds may occur due to the weed 
stage of growth at application, use rate, or environmental 
conditions at the time of application . 
When any of these conditions exist, select a higher rate 
within the label rate range to improve weed control . 
DO NOT retreat weeds with Liberty 280 SL until sufficient 
regrowth has occurred .

Compatibility Testing
If Liberty ® 280 SL herbicide is to be mixed with pesti -
cide products not listed on this label, test the compatibility 
of the intended tank mixture prior to mixing the products in 
the spray tank . T he following procedure assumes a spray 
volume of 25 gallons per acre . F or other spray volumes, 
adjust the amount of the water used accordingly . C heck 
compatibility as follows:
1 . Place 1 .0 pi nt 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 te aspoons to the jar .
3 . For each 16 fl ozs of a liquid tank mix partner to be 
applied per acre, add 0 .5 te aspoon to the jar .
4 . For each 16 fl ozs of Liberty 280 SL to be applied per 
acre, add 0 .5 te aspoon 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
Liberty 280 SL is formulated to mix readily in water . P rior 
to adding Liberty 280 SL to the spray tank, ensure that 
the spray tank is thoroughly clean, particularly if a herbi -
cide with the potential to injure crops was previously used 
(see Cleaning Instructions
) . I t is the pesticide user’s 
responsibility to ensure that all products are registered for 
the intended use . R ead and follow the applicable restric-
tions and precautions and directions for use on all product 
labels involved in tank mixing . Us ers must follow the most 
restrictive directions for use and precautionary statements 
of each product in the tank mixture .
Tank Mix Instructions. Li berty 280 SL may be applied 
in tank mix combinations with labeled rates of other prod-
ucts provided these other products are labeled for the 
timing and method of application for the crop to be treat-
ed . The tank mix partner must be used in accordance with 
the label restrictions and precautions . No label dosage 
rates may be exceeded . L iberty 280 SL cannot be mixed 
with any product containing a label prohibition against 
such mixing . Refer to the specific crop section for rates 
and other restrictions .
Mixing Instructions for Liberty 280 SL
1 . Start with 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 part -
ner, prepare a slurry of the proper amount of the 
product in a small amount of water . A dd the slurry to the 
spray tank .
5 . Add ammonium sulfate (AMS) to the spray tank if 
needed .
6 . If mixing with a liquid tank mix partner, add the liquid 
mix partner next .
7 . Complete filling the spray tank with water before add -
ing Liberty 280 SL, as foaming may occur .
8 . Add Liberty 280 SL when tank is full and continue 
agitation .
9 . If foaming occurs, use a silicone-based anti-foam 
agent
 .
Ensure that all spray system lines including pipes, booms, 
etc . h ave the correct concentration of spray solution by 
flushing out the spray system lines before starting the crop 
application .
If tank mix partners listed on this label are added, maintain 
thorough 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 . S creen size in nozzles or line 
strainers must be 50 mesh or larger .
Cleaning Instructions
Prior To Liberty 280 SL Use
Before using Liberty 280 SL , thoroughly clean bulk stor-
age tank, refillable tank, nurse tanks, spray tank, lines, and 
filter particularly if a herbicide with the potential to injure 
crops was previously used . Equi pment must be thoroughly 
rinsed using a commercial tank cleaner and as instructed 
on the prior herbicide label .
After Liberty 280 SL Use
After using 
 Liberty 280 SL , triple rinse the spray equip-
ment and clean with a commercial tank cleaner before 
using the equipment for a new application . Make sure any 
rinsate or foam is thoroughly removed from spray tank and 
boom . R insate may be disposed following the pesticide 
disposal directions on this label .
Application Instructions
Uniform, thorough spray coverage is necessary to 
achieve consistent weed control with Li berty 280 SL.
Ground Application
• Apply early when weeds are small with directed rates as 
identified in the Weeds Controlled
 section .
• Apply Liberty 280 SL in a minimum of 15 gallons of 
water per acre . I ncrease to 20 gallons of water per acre 
for better coverage of large weeds, dense foliage, or 
when using larger spray droplets .
Nozzle Selection
Apply with nozzles and pressure that deliver medium to 
coarse spray droplets as indicated in nozzle manufacturer’s 
catalogues and in accordance with ASABE Standard 572 .1 
unless otherwise mandated by tank mix product .

11
Addition of some drift retardants can significantly increase 
the droplet size and reduce spray coverage and efficacy . I f 
a drift retardant is used, ensure that it is compatible for use 
with Liberty ® 280 SL herbicide and spray equipment 
being used .
Aerial Application
• Apply early when weeds are small with directed rates as 
identified in the Weeds Controlled
 section .
• Apply Liberty 280 SL in a minimum of 10 gallons of 
water per acre .
• See the Spray Drift Management section of this label 
for additional information on proper application of 
 Liberty 280 SL .
Application Restrictions
• D O NOT apply when winds are gusty or when condi -
tions will favor movement of spray particles off the 
desired spray target . S ee the Spray Drift Management 
section of this label for additional information on proper 
application of Liberty 280 SL
 .
• DO NOT use flood jet nozzles, controlled droplet 
application equipment, or air-assisted spray 
equipment.
Adjuvant Instructions
• Ammonium sulfate (AMS) can be used at 1 .5 lb s/A to 
3 lbs/A . R ates are dependent on tank mix partners, 
 environmental conditions, temperatures and potential for 
leaf burn .
• AMS has shown to improve weed con tr ol of di fficult- 
to-control weeds, like velvetleaf and lambsquarters, 
under difficult environmental conditions (low relative 
humidity) or hard water .
• Anti-foam agent is advised . 
• No additional surfactant is needed with any tank mix 
partner . 
The use of additional surfactants or crop oils may increase 
the risk of crop response . P lease refer to the surfac ta nt 
label for more detailed information .
Mandatory Spray Drift Mitigation
• When applying to crops via aerial application equip -
ment, the spray boom must be mounted on the aircraft 
so as to minimize drift caused by wing tip or rotor 
blade vortices . T he boom length must not exceed 75% 
of the wingspan or 90% of the rotor blade diameter .
• When applying to crops via aerial application equip -
ment, applicators must use 1/2 swath displacement 
upwind at the downwind edge of the field .
• DO NOT apply when wind speeds exceed 10 miles 
per hour at the application site .
• DO NOT apply during temperature inversions .
• For aerial applications, DO NOT release spray at a 
height greater than 10 feet above the crop canopy, 
unless a greater application height is required for pilot 
safety .
• 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 .
• 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 . S et boom to lowest effective height over the 
target pest or crop canopy based on equipment 
 manufacturer’s directions . Au tomated 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 .
Advisory Spray Drift Language
• Pollinator Advisory Statement - This product con-
tains a herbicide . F ollow all label directions and 
precautions to minimize potential off-target exposure in 
order to prevent effects to non-target plants adjacent to 
the treated site which may serve as habitat or forage for 
pollinators .
• Spray Drift Management - The interaction of many 
equipment and weather-related factors determines the 
potential for spray drift . Th e 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 large droplets . T he 
best drift management strategy is to apply the largest 
droplets that provide sufficient coverage and control . T he 
presence of sensitive species nearby, the environmental 
conditions, and pest pressure may affect how an appli -
cator balances drift control and coverage . A PPLYING 
LARGER DROPLETS REDUCES DRIFT POTENTIAL, 
BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE 
MADE IMPROPERLY OR UNDER UNFAVORABLE ENVI-
RONMENTAL CONDITIONS! See Wind; Temperature 
and Humidity ; and Temperature Inversions sections 
of this label .

12
Techniques for Controlling Droplet Size
• Volume - Use high flow rate nozzles to apply the highest 
practical spray volume . N ozzles with higher rated flows 
produce larger droplets .
• Pressure - Use the lower spray pressures specified for 
the nozzle . H igher pressure reduces droplet size and 
does not improve canopy penetration . W HEN HIGHER 
FLOW RATES ARE NEEDED, USE A HIGHER- 
CAPACITY NOZZLE INSTEAD OF INCREASING 
PRESSURE .
• Nozzle Type - Use a nozzle type that is designed for the 
intended application . W ith most nozzle types, narrower 
spray angles produce larger droplets . Co nsider using 
low-drift nozzles .
Controlling Droplet Size – Aircraft
• Number of Nozzles - Use the minimum number of noz-
zles with the highest flow rate that provide uniform 
coverage .
• Nozzle Orientation - Orienting nozzles so that the 
spray is emitted backwards, parallel to the airstream will 
produce larger droplets than other orientations . AV OID-
ING SPRAY DRIFT IS THE RESPONSIBILITY OF THE 
APPLICATOR .
• Nozzle Type - Solid stream nozzles (including disc and 
core with swirl plate removed) oriented straight back pro-
duce larger droplets than other nozzle types .
• Boom Length - Longer booms increase drift potential . 
Therefore, a shorter boom length is recommended .
• Application Height - Application more than 10 ft above 
the canopy increases the potential for spray drift .
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 .
Drift Reduction Technology (DRT). The EPA Drift 
Reduction Technology (DRT) Program was developed to 
encourage the manufacture, marketing, and use of spray 
technologies scientifically verified to significantly reduce 
pesticide drift . T he use of DRTs should result in significant-
ly less pesticide from spray applications drifting and being 
deposited in areas not targeted by those applications, 
compared to spray technologies that do not meet the mini-
mum DRT standard . EP A-verified drift reduction 
technologies (DRTs) and their ratings will be added to the 
following webpage as they become available: 
https://www .ep a .go v/reducing-pesticide-drift/epa-verified- 
and-rated-drift-reduction-technologies .
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 equip-
ment type determine drift potential at any given wind 
speed . A VOID APPLICATIONS DURING GUSTY OR 
WINDLESS CONDITIONS . NOTE: Local terrain can influ-
ence wind patterns . E very applicator needs to 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 . Te mperature inversions restrict verti-
cal air mixing, which causes small suspended droplets to 
remain close to the ground and move laterally in a concen-
trated cloud . Te mperature inversions are characterized by 
increasing temperature with altitude and are common on 
nights with limited cloud cover and light to no wind . T hey 
begin to form as the sun sets and often continue into the 
morning . T heir presence can be indicated by ground fog; 
however, if fog is not present, inversions can also be identi-
fied by the movement of smoke from a ground source or an 
aircraft smoke generator . S moke that layers and moves lat-
erally 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 noz-
zles can reduce the effects of wind . H owever, 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 Methods to non Glufosinate-
resistant Cotton
Application of Liberty 280 SL to non glufosinate-resistant 
cotton varieties requires the use of hooded spray equip -
ment designed to minimize exposure of the spray to the 
cotton stand . A h ooded sprayer directs the spray onto 
weeds, while shielding the cotton stand from contact . Us e 
nozzles that provide uniform coverage within the treated 
area . K eep hoods on these sprayers adjusted to protect 
desirable vegetation . E xtreme 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 . Thi s 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 skim -
ming across the ground . T ractor speed must be adjusted 
to avoid bouncing of the spray hoods . A void operation on 
rough or sloping ground where the spray hoods might be 
raised off the ground . I f the hoods are raised, spray parti-
cles may escape and come into contact with the cotton, 
causing damage or destruction of the crop .
Herbicide rates and spray volume instructions are present -
ed as broadcast equivalents and must be reduced in 
proportion to the area actually treated . Us e the following 
formulas to calculate the correct rate and volume per 
planted (field) acre:

Application Directions for 
Potato Vine Desiccation
Application Rate and Timing
Apply Liberty 280 SL at the beginning of natural senes-
cence of potato vines and when petiole nitrate levels are 
below 15,000 ppm . A pply 21 fl ozs/A . DO NOT split this 
application or apply more than one application per harvest . 
Potato varieties with heavy or dense vines may require an 
application of an additional desiccation product to com -
plete vine desiccation .
Thorough coverage of the potato vines to be desiccated is 
essential . Us e a sufficient volume of water (20 to 100 GPA) 
to obtain thorough coverage of the potato vines . V ary the 
gallons of water per acre and the spray pressure as indi-
cated by the density of the potato vines to assure thorough 
spray coverage . I ncrease the spray volume to at least 
30 gallons of water per acre when the potato vine canopy 
is dense or under cool and dry conditions . A pply 
 Liberty 280 SL with the spray boom as low as possible to 
achieve thorough coverage of the potato vines for best 
control and to minimize drift potential .
The use of additives or adjuvants may improve the perfor-
mance of Liberty 280 SL in desiccating potatoes .
