GENERAL INFORMATION 
Flexstar GT Herbicide may be applied as a preplant or preemergence burndown 
application in cotton or as a postemergence directed application in glyphosate-tolerant 
(GT) cotton and as a preplant or preemergence burndown in soybeans or as a 
postemergence over-the-top application in glyphosate-tolerant (GT) soybeans to control 
labeled broadleaf, grass and sedge weeds.

-7-
Environmental and Agronomic Conditions 
Always apply Flexstar GT Herbicide under favorable environmental conditions that 
promote active weed growth. Avoid applying Flexstar GT Herbicide to weeds which are 
under stress from drought, extreme temperatures, excessive water, low humidity, low 
soil fertility, mechanical or chemical injury as reduced weed control and/or increased 
crop injury may result. 
Preplant Surface, Preemergence or Postemergence Applications 
Flexstar GT Herbicide wi" control or partially control certain germinating broad leaf 
weeds and sedges by soil residual activity from either preplant surface, preemergence 
or postemergence applications that come in contact with the soil. Moisture is necessary 
to activate Flexstar GT Herbicide in soil for residual weed control. Dry weather following 
applications of Flexstar GT Herbicide may reduce effectiveness. When adequate 
moisture is not received within 7 days after a Flexstar GT Herbicide application, weed 
control may be improved by overhead irrigation with at least a % inch of water. 
Cultivation 
Cultivation prior to postemergence application is not recommended. Weeds may be put 
under stress by cultivation thus reducing weed control. Timely cultivation 2-3 weeks 
after applying Flexstar GT Herbicide may assist weed control. 
Information on Weed Resistance 
Flexstar GT Herbicide contains glyphosate which inhibits 5-enolpyruvylshikimate-3-
phosphate (EPSP) synthase (Group 9 herbicide) and fomesafen which inhibits 
protoporphyrinogen oxidase (PPG oxidase or Protox) (Group 14 herbicide). Some 
naturally occurring weed populations have been identified as resistant to Group 9 and 
Group 14 herbicides. Selection of resistant biotypes, through repeated use of these 
herbicides in the same field, may result in weed control failures. A resistant biotype 
may be present if poor performance cannot be attributed to adverse environmental 
conditions or improper application methods. If resistance is suspected, contact your 
local Syngenta representative or agricultural advisor for assistance. 
Glyphosate Resistance 
Some naturally occurring weed biotypes resistant to glyphosate may exist through 
normal genetic variability in any weed population. The repeated use of herbicides with 
the same mode of action is known to lead, under certain conditions, to a selection of 
resistant weeds. Certain agronomic practices reduce the likelihood that resistant weed 
populations will develop and integrated strategies are known to manage such problem 
weeds.

-8-
Glyphosate is one of the active ingredients in Flexstar GT Herbicide, so glyphosate 
resistance management is critical. Flexstar GT Herbicide will control or partially control 
several broadleaf weeds that are showing increased tolerance or resistance to 
glyphosate. Flexstar GT Herbicide will not provide control of emerged grasses that are 
resistant to glyphosate. 
The following is a list of Best Weed Management practices to be considered in 
glyphosate-based programs. 
• In Roundup Ready® (RR) corn and RR soybean systems do not use more than two 
applications of a glyphosate-based herbicide over a two-year period. Diversify with 
alternative mode of action herbicides and/or cultural practices. 
• In RR cotton, a maximum of three applications of a glyphosate-based herbicide may 
be used if employing in-crop cUltivation and/or residual herbicides. 
• Use alternative (non-glyphosate) burndown and/or residual herbicides for RR crops 
likely to require more than one application of glyphosate. 
• To help manage RR resistant volunteers rotate RR crops with conventional or non­
RR crops. 
• Use full labeled rates of glyphosate and tank-mix partners. Minimize weed escapes. 
• Monitor treated weed populations for any loss of field efficacy. 
• Contact your local extension specialist, certified crop advisor, and/or Syngenta Crop 
Protection representative for herbicide resistance management and/or integrated 
weed management directions for specific crops and resistant weed biotypes. 
APPLICATION DIRECTIONS 
Drift Management 
Avoiding spray drift at the application site is the responsibility of the applicator and the 
grower. The interaction of many equipment and weather-related factors determines the 
potential for spray drift. The applicator and grower must consider the interaction of 
equipment and weather-related factors to ensure that the potential for drift to sensitive 
nontarget plants is minimal. 
This pesticide is to be applied only when the potential for drift to adjacent sensitive 
areas (e.g., residential areas, bodies of water, nontarget plants) is minimal (i.e., when 
the wind is blowing away from the sensitive area).

-9-
Spray Adjuvants 
Flexstar GT Herbicide is specifically formulated with the ISOLlNKTM Technology II that 
minimizes the need for additional spray adjuvants. Under certain conditions, burndown 
and postemergence activity may be improved by adding one or more of the following 
spray adjuvants: 
Ammonium Sulfate (AMS) at 8.5 to 17 Ib./100 gallons of water should be added in 
areas where commonly used with glyphosate containing products. Liquid formulations 
of AMS may be used at an equivalent rate. 
One of the following spray adjuvants can be added for difficult to control weeds 
or under adverse conditions: 
Crop Oil Concentrate (COC) or Methylated Seed Oil (MSO): Use a nonphytotoxic 
COC or MSO containing 15-20% approved emulsifier at 0.5-1% v/v (2-4 quarts/100 
gallons) of finished spray volume. COC or MSO can improve weed control but may 
reduce crop tolerance. 
Nonionic Surfactant {NIS}: Use NIS containing at least 80% active ingredient at 0.25-
0.5% v/v (1-2 quarts/100 gallons) of finished spray volume. 
The use of deposition (drift control) agents that impact droplet size and coverage may 
reduce weed control. 
Recommended Tank Mixing Order 
1. Fill the spray tank with % to ~ the required amount of water and begin agitation. 
2. Add AMS (if used). 
3. Add dry pesticide formulations (WP, OF, etc.). 
4. Add liquid pesticide formulations (EC, SC, etc.). 
5. Add Flexstar GT Herbicide. 
6. Add COC, MSO or NIS (if used). 
7. Add the remaining water and maintain agitation throughout the spray operation. 
Be sure to allow each tank-mix component to fully disperse before adding the next.

-10-
Ground Application 
Use sufficient spray volume and pressure to ensure complete coverage of the target. A 
spray volume of 15-20 gallons per acre and 30-60 psi at the nozzle tip is recommended. 
When foliage is dense, use a minimum of 20 gallons per acre to ensure adequate 
coverage. 
The use of flat fan nozzles will result in the most effective postemergence application of 
Flexstar GT Herbicide. Use nozzles that are set up to deliver medium quality spray 
(ASAE Standard S-572). 
DO NOT USE AIR-INDUCTION, FLOOD TYPE OR OTHER SPRAY NOZZLES WHICH 
DELIVER COARSE, LARGE DROPLET SPRAYS. 
Aerial Application 
Use sufficient spray volume and pressure to ensure complete coverage of the target. A 
minimum of 5 gallons per acre of spray mixture should be applied with a maximum of 40 
psi pressure. When foliage is dense, use a minimum of 10 gallons per acre to ensure 
coverage of weed foliage. 
DO NOT APPLY THIS PRODUCT THROUGH ANY TYPE OF IRRIGATION SYSTEM. 
GENERAL PRECAUTIONS

COTTON 
Burndown and Residual Weed Control Applications 
Flexstar GT Herbicide can provide burndown of emerged weeds and residual control of 
certain germinating broad leaf weeds and sedges from either a !)replant surface or 
preemergence application in cotton. Apply as a preplant surface or preemergence 
treatment only to coarse textured soils (sandy loam, loamy sand, sandy clay loam). Do 
not apply as a preplant surface or preemergence treatment to medium or fine-textured 
soils as crop injury will likely occur. 
Refer to Table 1 for use rates and weeds controlled by pre plant surface or 
preemergence applications and Tables 2 and 3 for use rates, weed growth stages and 
weeds controlled by postemergence applications. 
Emerged weeds must have thorough spray coverage for effective control. Refer to the 
Spray Adjuvants section for directions on spray adjuvants for postemergence weed 
control. 
Moisture is necessary to activate Flexstar GT Herbicide in soil for residual weed control. 
Dry weather following application of Flexstar GT Herbicide may'reduce residual activity. 
When adequate moisture is not received within 7 days after a Flexstar GT Herbicide 
application, residual weed control may be improved with at least a 'X inch of overhead 
irrigation .. 
Cotton plants are tolerant to preemergence applications of Flexstar GT Herbicide when 
applied at specified rates and to coarse-textured soils. Some crinkling or spotting of 
cotton foliage or stunting may occur, especially if heavy rainfall occurs during or soon 
after cotton emergence but cotton plants normally outgrow these effects and develop 
normally. 
Tank Mixes for Burlid6wli aiidResidualWeed Control Applic-ations 
Flexstar GT Herbicide can be applied in a tank mix with the following products: 
Caparol®, Cotoran®, Dicamba, Direx®, Glyphosate products (such as Touchdown® or 
Roundup® brands), Karmex®, Prowl® H20, Solicam®, and Staple®. Refer to individual 
product labels for precautionary statements, restrictions, rates and a list of weeds 
controlled. 
Post-Directed Application in Roundup Ready Flex Cotton

broadcast or banded. Post-directed applications of Flexstar GT Herbicide will provide 
contact control of labeled weeds and residual preemergence control of labeled weeds 
(once activated by rainfall or irrigation). Refer to Table 1 for weeds controlled or 
partially controlled through residual activity and Tables 2-3 for weeds controlled by 
postemergence activity. Do not exceed 3 pts.lA as a post-directed application in 
Roundup Ready Flex cotton. 
Cotton foliage is not tolerant to Flexstar GT Herbicide applications. Avoid contact to 
cotton foliage as unacceptable injury will occur. Application equipment should be 
calibrated (spray pressure, nozzle type and configuration, and orifice size) to avoid fine 
spray droplets contacting green cotton stems and foliage. 
Post-Directed Application Timing in Roundup Ready Flex Cotton 
Flexstar GT Herbicide may be applied as a post-directed application to Roundup Ready 
Flex cotton when cotton is at least 6 inches in height through layby. All post-directed 
applications should avoid spray contact with any green non-barked parts of the cotton 
plant or foliage as unacceptable injury will occur. Follow the application timing 
recommendations below for post-directed applications in Roundup Ready Flex cotton. 
Shielded and Hooded Applications 
Make a precision post-directed Flexstar GT Herbicide application to the Qase of 
the cotton plant avoiding contact with the cotton stem or foliage when cotton is at 
least 6 inches in height to avoid cotton injury. Use only hooded or shielded spray 
equipment to apply Flexstar GT Herbicide in cotton that is 6 inches in height. 
Adjust nozzles to provide full coverage of emerged target weeds. 
Layby Applications

AERIAL SPRAY DRIFT MANAGEMENT ADVISORY 
Spray Drift Management 
AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF 
THE APPLICATOR. The interaction of many equipment and weather-related factors 
determines 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 
formulations. 
1. The distance of the outer most nozzles on the boom must not exceed % the 
length of the wingspan or rotor. 
2. Nozzles must always point backward parallel withtheairstrealTl and never be 
pointed downwards more than 45 degrees. 
Where states have more stringent regulations, they must be observed. 
The applicator must be familiar with and take into account the information covered in the 
Aerial Drift Reduction Advisory Information. 
Aerial Drift Reduction Advisory Information 
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

-29-
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 Inversion sections of this label). 
Controlling Droplet Size 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. 
Nozzles with higher rated flows produce larger droplets. 
• 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 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 backwards 
parallel to the airstream will produce larger droplets than other orientations. 
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 larger 
droplets than other nozzle types. 
Boom Length 
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 
Applications must 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 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.).

-30-
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. 
Application must be avoided below 2 mph due to variable wind direction and high 
inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator 
must 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. 
Temperature Inversions 
Applications must 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. 
Sensitive Areas 
The pesticide is to be applied only when the potential for drift to adjacent sensitive areas 
(e,g. residential areas,boElies·ofwater;known habitat for threatened or endangered 
species, nontarget crops) is minimal (e.g. when wind is blowing away from the sensitive 
areas).
