Applications of Glufosinate 280SL on sugar beets may be made from the cotyledon stage up to the 10-leaf stage of the sugar beet. Glufosinate 280SL is a foliar active material with no soil residual activity. Apply to young and actively growing weeds, targeting weeds less than 3 inches in height. For additional 

information on weed heights, refer to the WEED CONTROL FOR ROW CROPS section. Glufosinate 280SL will have an effect on weeds that are larger than the specified leaf stage, however, speed of activity and control may be reduced. 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 drought, cool temperatures, or extended periods of cloudiness. Glufosinate 280SL is rainfast 4 hours after application, therefore rainfall within 4 hours may necessitate retreatment. For best results, on lambsquarters, Palmer amaranth and velvetleaf control, make applications of Glufosinate between dawn and 2 hours before sunset.

Apply 29 – 36 fluid ounces per acre (0.53 – 0.66 lb. a.i./A) depending on weed species, size and density per weed chart. If a second application is needed, make the second application in a minimum of 10 days after the first application. The maximum annual rate of Glufosinate 280SL on sugar beets is 60 fl. oz./A (1.10 lbs. a.i./A).Use a minimum spray volume of 15 gallons per acre, unless there is a difficult to control situation (including dense canopy, large weeds or unfavorable growing conditions are present). In difficult to control situations, use a minimum spray volume of 20 gallons per acre.

Ammonium sulfate (AMS) may be used at 1.5 to 3.5 lbs./A. Adjuvant rates are dependent on a variety of factors including tank mix partners, environmental conditions (including temperature) and potential for leaf burn. AMS has shown to improve weed control of difficult-to-control weeds like lambsquarters and velvetleaf under difficult environmental conditions (including low relative humidity) or hard water. The use of an anti-foam agent is advised.

Surfactants/Oils
The use of additional surfactants or crop oils in tank mixes with Glufosinate 280SL may increase the risk of crop response. Please refer to the surfactant label for more detailed information.

Use medium to coarse nozzles. Glufosinate 280SL is a contact herbicide and requires proper nozzles with uniform thorough spray coverage to achieve optimum weed control.

• Do not apply more than 36 fl. oz./A (0.66 lb. a.i./A) of Glufosinate 280SL in one application.

• Do not apply more than 60 fl. oz./A (1.10 lbs. a.i./A) of Glufosinate 280SL on sugar beets per year.

• Do not make more than 2 applications per year.

• If a second application is needed, make the second application in a minimum of 10 days after the first application.

• Do not apply Glufosinate 280SL within 60 days of harvesting sugar beets.

• Do not plant rotation crops in a field treated with Glufosinate 280SL within 120 days after the last application of this product with the exception of wheat, barley, buckwheat, millet, oats, rye, sorghum, and triticale, which may be planted 70 days after the last application of this product. Corn, soybeans, canola, and sugar beets containing LibertyLink® trait may be planted at any time.

• Do not graze the treated crop or cut for hay.

• Do not add surfactants. Antifoams or drift control agents may be added if needed.

• Do not apply Glufosinate 280SL if sugar beets show injury from prior herbicide or environmental stress (drought, excessive rainfall, etc.).

• Do not apply this product through any type of irrigation system.
