GENERAL INFORMATION 
Read all label directions before using. 
FLEXSTAR is a selective postemergence herbicide for control of broad leaf weeds in soybeans. 
Soybean plants are tolerant to FLEXSTAR when applied at recommended rates. Some bronzing, 
crinkling or spotting of soybean leaves may occur, but soybeans soon outgrow these effects and 
develop normally. 
. -FLEXSTAR is effective through contact action, therefore weeds must be thoroughly covered with 
spray, Optimum weed control is achieved when young actively growing weeds are treated that 
are not under stress from moisture, temperature, low soil fertility, mechanical or chemical injury. 
Secondary flushes of certain weeds may be controlled by soil residual activity if rainfall occurs 
shortly after application. The extent of soil activity is dependent upon soil type, ground cover at 
time of application, amount of rainfall and the rate of FLEXSTAR used. • :

FLEXSTAR Booklet 
FLEX390B.RSD 5119/97 
APPLICATION DIRECTIONS 
TIMING: Best control of susceptible broadleaf weeds is obtained when FLEXSTAR is applied 
early to actively growing weeds. This usually occurs 14 to 28 days after planting. Refer to the 
weed tables for specific recommendations on weed growth stages, rates, and regions. 
SPRAY ADDITIVES: FLEXSTAR is formulated with an optimized surfactant system for 
herbicidal performance. 
In Regions 2, 3 and 4 (see Regional Use Map), FLEXSTAR should be used with a minimum of 
1.0% of liquid nitrogen (28% or similar) or a minimum of 4 pounds ammonium sulfate per 100 
gallons of spray volume. 
The use of FLEXSTAR with additional adjuvants, such as crop oil concentrate or nonionic 
surfactant can improve performance on larger and/or more difficult to control weeds or during 
drought stress or when spray volume exceeds 20 gallons per acre. ' Under certain conditions 
temporary crop injury may result. 
GUIDELINES FOR USING ADDITIONAL ADJUVANTS: Only spray additives cleared for use on 
growing crops under40 CFR 180.1001 may be used. 
Nonionic Surfactant (NIS) - Use NIS containing at least 75% surface active agent at 0.25% (1/2 
pint per 25 gallons) of the finished spray volume. 
Crop Oil Concentrate (COC) - Use a non phytotoxic COC or a once refined vegetable oil 
concentrate (VOC, MSO) containing 15-20% approved emulsifier at 0.5% (1 pint per 25 gallons) 
of finished spray volume. 
Other Adjuvants - Adjuvants other than COC or NIS may be used providing the product meets 
the following criteria: 
1. Contains only EPA exempt ingredients. 
2. Is non phytotoxiC to the target crop. 
3. Is compatible in mixture. (May be established through a jar test.) 
4. Is supported locally for use with FLEXSTAR on the target crop through proven field trials 
and through university and extension recommendations. 
Tankmixes: If a product tankmixed with FLEXSTAR requires a cropoil concentrate or nonionic 
surfactant, use the lowest recommended adjuvant rate for the tankmix product. (See Tankmix 
Application section for further details.) 
Recommended Mixing Order: 
1. Half required amount of water, begin agitation.* 
2. Dry pestiCide formulations. 
3. FLEXSTAR herbicide. 
4. Liquid pestiCide formulation. 
5. Adjuvant (COC or NIS) and fertilizer. '", ,

FLEXSTAR Booklet 
FLEX390B.RSD 5119197 
GROUND APPLICATION: Use sufficient spray volume and pressure to ensure complete 
coverage of the target weeds. A spray volume of 10-20 gallons per acre and 30-60 psi at the 
nozzle tip is recommended. When weed foliage is dense, use 60 psi and a minimum of 20 
gallons per acre to ensure coverage of weed foliage. 
Use only hollow cone or flat fan nozzles. The sprayer must be calibrated to provide the proper 
volume and rate per acre. In addition, the boom and nozzle height must be adjusted to provide 
complete coverage of all weeds. 
DO NOT USE FLOOD TYPE OR OTHER SPRAY NOZZLES, WHICH DELIVER COARSE, 
LARGE DROPLET SPRAYS. 
DO NOT APPLY THIS PRODUCT THROUGH ANY TYPE OF IRRIGATION SYSTEM. 
BAND APPLICATIONS: Thorough weed coverage is important for control. Best coverage is 
obtained with a minimum of two n=les, one directed to each side of the planted row. 
Application with a single nozzle directed over the top of the row is not recommended. Cultivation 
of untreated areas may be needed following band applications. When making band applications 
and cultivating in the same operation, position nozzles in advance of the cultivation device. This 
will reduce dust in the spray area. Dust can intercept spray, reducing weed coverage, resulting 
in less than adequate weed control. 
Calculate the amount of herbicide and water volume needed. for band treatment by the following 
formulas: 
ElSlnd ~idth in inches X broadcast rate = Band herbicide rate 
row width in inches per acre per acre 
Baod width in ios;,hes X broadcast volume = Band water volume 
row width in inches per acre per acre 
AERIAL APPLICATION: Use sufficient spray volume and pressure to ensure complete 
coverage of the target weeds. A minimum of 5 gallons per acre of spray mixture should be 
applied with a maximum of 40 PSI pressure. When broadleaf weed foliage is dense, use a 
minimum of 10 gallons per acre to ensure coverage of weed foliage. 
CULTIVATION: Cultivation prior to application is not recommended. Cultivation may put w~eds 
under stress, reducing weed control. Timely cultivation 1-3 weeks after applying FLEXSTAR 
may assist weed control. 
GENERAL USE PRECAUTIONS

• Tankmixes of FLEXSTAR herbicide with other pesticides, fertilizers or any other additives 
except as specified on this label or other approved ZENECA supplemental labels may result 
in tankmix incompatibility, unsatisfactory performance andlor unsatisfactory crop injury. 
• FLEXSTAR herbicide requires a 1-hour rain-free period for best results. 
• Apply to actively growing weeds. Avoid applying FLEXSTAR to weeds or soybeans which are 
under stress from moisture, temperature, low soil fertility, mechanical or chemical injury, as 
reduced weed control andlor increased crop injury may result. . . 
• Avoid overlapping spray sweths, as injury may coeur to rotational crops. 
• Avoid drift to all other crops and nontarget areas. Crops other than soybeans may be severely 
injured by drift. Do not apply when wind velocity exceeds 15 mph. be not make ground or 
aerial application during temperature inversions. 
• To provide adequate coverage, it is recommended that ground speed not exceed 10 MPH 
during application. 
• Do not graze treated areas or harvest for forage or hay.

SPECIAL USE DIRECTIONS FOR ADDITIONAL WEED PROBLEMS 
Suppression of Annual Grasses: 
The grasses listed below may be suppressed by applications of FLEXSTAR at 2-3 pints/acre. 
Consult Use Rate Table for maximum rate in each region. For full-season broad-spectrum 
annual grass control, FUSILAO~ OX or FUSION"' herbicide should be used alone or in tankmix 
with FLEXSTAR. Consult tankmix section.

Green 
Yellow 
Goosegrass 
Johnsongrass, Seedling 
Panicum, Fall 
Panicum, Texas 
Suppression of Perennial Weeds: 
Use of FLEXSTAR at rates of 2 to 3 pints/acre will aid in suppressing the above-ground portions 
of the weeds listed below until crop canopy can assist in suppression. Perennial weeds continue 
to regrow from underground rootstocks even if above-ground foliage is temporarily controlled or 
retarded. Even though FLEXSTAR and crop competition can suppress perennial weeds for a 
growing season, the rootstocks will continue to live and reestablishment will occur in subsequent 
years.

FLEX3908.RSD 5/19/97 
For sequential applications allow 2-3 days after the application of the grass herbicide before 
applying FLEXSTAR or FLEXSTAR mixtures. In case FLEXSTAR or the FLEXSTAR mixture is 
applied first apply the grass herbicide when the grass weeds begin to develop new leaves 
(generally around 7 days). 
• Tankmix applications can result in increases in crop injury as compared to either product 
used alone. 
• It is recommended no additional adjuvants be added to FLEXSTAR plus Pinnacle or 
Pinnacle containing premixes. 
• Do not exceed 1 fluid ounce of 8utyrac per acre in mixture with FLEXSTAR. 
Always read and follow the restrictions and limitations for all products whether used alone, 
sequentially or in a tankmix. The most restrictive labelling of any product used applies.
