**USE INFORMA** 

**TION**
Flazasulfuron is a selective herbicide for preemergence and postemergence control of certain broadleaf weeds and grasses in citrus, grape, sugarcane, tree nuts, conifer trees and for use in industrial vegetation ma nagem ent in specified nonagricultural areas. Flazasulfuron is absorbed through the root and foliage of plants, rapidly inhibiting th e growth of susceptible weeds. For preemergence ap plication, rainfall or irrigation is needed for herbicide activation. Length of control is a function of environmental factors such as soil type, soil mo isture, temperature and am ount of moisture after the application. Existing weeds or crop residue may reduce the length and level of residual control

. We ed control may a lso be reduced due to environmental stress to the weeds at the tim e of the application.
Weed growth stops within hours after the application, however symptom progress from discoloration o r chlorosis to necrosis generally requires from 2 to 4 weeks. S peed of control is generally a function of weather with faster action during warmer weather and actively growing weeds. T he best control is obtained when ISK Flazasulfuron Herbicide is applie d either to weeds just prior to germination or to yo ung, actively growing weeds. For optimal herbicidal activity, prior to application, the bed or soil surface should be reasonably even and clear of crop and weed residue . Before herbicide application, crop and weed residue can be mixed into the soil through cultivation, or removed by blowing the area to be treated. Any practices that cause disturbance of the soil surface after herbicide treatment will decrease herbicidal activity. If rainfall does not o ccur within 2 weeks after a preemergence, application 1⁄4 to 1⁄2 inch of irrigation water should be applied. Do not apply more than 1 inch of irrigation water. ISK Flazasulfuron Herbicide controls weeds by i nhibiting the acetolactate synthase (ALS) bioche mi cal process. S om e weeds may contain naturally occurring populations that are resistant to ALS inhibiting herbicides. Applications of ALS inhibiting herbicides, when used alone, over a period of time may lead to biotyp es that are resistant to ALS herbic ides. T his then leads to a reduction in the level of control obtained through the use of these herbicides. To prevent or delay the build

- up of ALS resistant weeds, weed ma nagement programs should include the use of appropriate registered herbicides for control of these weeds that have a different mode of action. Applications of herbicides with a different mode of action should be used during the same year or in sequential years. 

### AP **PLICA**

**TION RESTRICT IONS**  **FOR A LL USES** 

 Do not apply ISK Flazasulfuron Herbi cide aerially.

 Do not apply ISK Flazasulfuron Herbicide through any irrigation system.

 Do not apply to saturated soils.

 Do not apply to plants that are under stress due to drought, standing water, heavy insect and/or disease pressure, low soil fertility, etc.

 Do not mechanically incorporate into the soil

.  Do not apply more than 0.15 lb ai per acre per year.

 A 25 foot buffer for ground applications must be maintained between the point of direct application and the closest downwind edge of sensitive terrestri al habitats (including grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrub lands), sensitive freshwater habitats (including lakes, rivers, sloughs, ponds, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.



### SPRA **Y DRIFT MA NA** **GEME NT** 

 The applicator must be familiar with the effects of temperature inversions.

 Apply as a medium or coarser spray (ASAE Standard 572).

### 5  AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR AND GROW ER. The interaction of many equipment and weather

- related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all factors involved in minimizing drift potential. Wh ere states have more stringent regulations, they mu st be observed.

 Avoid making applications when spray particles may be carried by air currents to areas where sensitive crops and plants are growing. Do not spray near sensitive plants if wind is gusty, below 2 mph, or in excess of 10 mph and moving in the direction of adjacent areas of sensitive crops or plants. Do not apply during temperature inversions. Always make applications when there is some air movement to determine the direction and distance of possible spray drift.

 To avoid injury to desirable plants, equipment used to apply ISK Flazasulfuron Herbicide should be thoroughly cleaned (see PROCEDURE FOR CLEANING SPRAY EQUIPMENT) before reusing to apply any other chemicals.

 Apply using a nozzle height of no more than 2 fe et above the ground or crop canopy

.



### INFORMATION ON DROPLET SIZE The best drift management strategy is to apply large droplets and to limit or eliminate small droplets. Applying large droplets reduces drift potential, but will not prevent drift if appl ications are ma de im properly or under unfavorable environmental conditions (see sections below). 

### CONTROLLING DROPLET SIZE

 Volume

- Use sufficient volume to form droplets large enough to avoid drift potential.

 Pressure

– Pressure and nozzle type and orie ntation should be carefully managed to avoid formation of fine droplets.

 Number of nozzles

- Use the minimum number of nozzles that provide uniform coverage.

 Nozzle Type - Use a nozzle type that is designed for the intended application. W ith m ost nozzl e typ es, narrower spray angles produce larger droplets. Consider using low

- drift nozzles. Properly designed solid stream nozzles should produce the lowest drift potential. Select nozzles, which do not have a wide discharge profile. 

### CALIBRATION Equipment should be calibrated regularly according to manufacturer’s specifications. 

### WI ND Applications mu st not be made when wind exceeds 10 mph. Use caution when applying in wind speeds less than 2

- 3 mph because a temperature inversion may be present and wind di rection may vary. Many factors, including droplet size and equipment type , determine drift potential at any given wind speed. Note: Local terrain can influence wind patterns. The applicator mu st be fa mi liar with local wind patterns and mu st mo nitor wind co nditions at the site at the tim e of application. 

### SENSITIVE AREAS The pesticide must only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, no n target crops) is minimal (e.g., when wind is blowing away from the sensitive areas).”

### 6

TEMPERATURE AND HUMIDITY Low humidity and high temperature increase the evaporation rate of droplets and therefore increase spray drift potential. The applicator mu st com pensate for temperature and humidity. 

### TEMPERATURE INVERSIONS Because of high drift potential, applications mu st not be made when droplets may reach a temperature inversion layer. It is the applicator's responsibility to identify the presence of a te mp erature inversion at the time of application. Accurate measurements of temperature, relative hum idity, and wind speed help determine if an inversion exists. Local sources of weather information may

help identify the presence of temperature inversions. 

### MI XING AND LOADING INSTRUCTIONS
Ensure the spray system is clean and free of residues from previous applications. F ill the spray tank 1/2 full with clean water. E nsure the agitation system is operating and sufficient to provide uniform spray mixing during application and until the spray tank has been em ptied. Add the appropriate am ount of this product to the spray tank. Complete filling the spray tank to the desired level. Prepare no more spray mixture than is needed for the immediate application. Avoid the overnight storage of ISK F lazasulfuron Herbicide spray mixtures. **Tank Mixtures** Tank mixes are generally used to broaden or extend control of the weed spectrum present. T ank mix herbicides must be registered for use on the intended crop. ISK F laza sulfuron Herbicide may b e tank mixed with herbicides specified for use on labeled crops. Read and follow all label directions for each tank mix herbicide

. Always follow precautions and restrictions on the most restrictive tank mix partner. ISK F lazasul furon Herbicide is generally com patible with insecticides (non

-organophosphate), fungicides, fertilizers and mi cronutrient products provided sufficient free water is available for dispersion of all the tank mix products. H owever, the physical compatibility of ISK F lazasulfuron Herbicide with tank mix partners should be evaluated before use. Use tank

- mix com binations only when applicator experience indicates that the tank mix will not result in objectionable crop injury.

For tank mixtures, add individual components to the spray tank in the following sequence: water, water dispersible granules (this product), water

-soluble bags, dry flowables, em ulsifiable concentrates, drift control additives, water

-soluble liquids, and nonionic surfactants

. **Ad ditive**  **Use Requirements**  The use of a non - ionic surfactant at 0.25 percent by volume (1 qt / 100 gal) provides a m axim um performance for all postem ergence applications. S urfactant products mu st contain at least 50% nonionic surfactant (see label of adjuvant). Petrol eum crop oil concentrate or methylated seed oil at 1% by volume (1 gal / 100 gal) can also enhance herbicide performance. Oil adjuvants mu st contain at least 15% surfactant em ulsifiers and 80% high quality p etroleum or methylated seed oil (see label of cro p or seed oil). I f another herbicide is tank mixed with ISK F lazasulfuron Herbicide , select additives authorized for use with both products. **Compatibility Test** Additives and tank mixes should be tested for compatibility by mixing in a small container prior to mixing in spray tank. In a lidded glass jar (~1 quart size), add all mix partners, in their relative proportions. Invert, shake or mix the jar thoroughly.

### 7

If mixture forms precipitates (flakes or sludge), gels, balls up or forms oily films or l ayers, this indicates incompatibility. Though signs of incompatibility will typically be seen within 5 minutes of mixing, mixture should be observed for approximately 30 minutes. Compatibility agents can be used to facilitate mixing. Add 1⁄4 teaspoon of t he compatibility agent to the mix (assuming a mixing rate of 2 pints compatibility agent per 100 gallons spray mix). If compatibility agents to do not facilitate mixing, the mixture is incompatible and should not be used.
**Spray Equipment Clean Out:** After spraying ISK F lazasulfuron Herbicide and before using sprayer equipment for any other applications, the sprayer must be thoroughly cleaned using the following procedure. 1. Drain tank; thoroughly rinse inside of spray tanks with clean water (rinse ab out 1 minute per 25 gallons of tank capacity). Loosen and physically remove any visible deposits with a stiff brush. 2. Fill the tank with clean water and add 1 gallon of household ammonia (contains at least 3% active ingredient) for every 100 gallons of water. Circulate the cleaning solution through the tank and hoses for at least 15 minutes. Flush the cleaning solution through the hoses, boom and nozzles (1/4 volume of tank capacity) and then drain the tank. 3. Repeat step 1. 4. Repeat step 2. 5. Remove the nozzle s and screen and clean separately in a bucket containing cleaning agent and water. 6. Rinse the tank, boom and hoses with clean water. 7. If only ammonia is used as a cleaner, the rinsate solution from both steps 2 and 4 may be applied back to the crop (s) as spe cified on the label. Do not exceed the maximum label use rate. If other cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility. (Attention: Do Not use Chlorine bleach with ammonia as a dangerous gas will form).
