General Information


This product is a herbicide for use in cotton, fruit, nuts, golf-courses, turf, grass seed crops, forestry, and non-crop areas. This product contains a surfactant (wetting agent). Additional surfactant may be required depending on the application spray volume. Local conditions and recommendations vary; consult local agricultural experiment station or extension service weed specialists for recommendations in your area.


This product should be applied with a low-volume, low-pressure, properly calibrated sprayer having satisfactory pumping and bypass action. For ground directed spray applications adjust nozzles in a manner to allow maximum coverage of weeds (and in a manner to keep spray off cotton foliage). DO NOT apply with hose-end applicators. This product is somewhat corrosive to certain metals; therefore, use in galvanized steel or aluminum equipment is not recommended.

For aerial application with fixed-wing aircraft or helicopter application, an exactly even swath deposition cannot be achieved, and consequently crop injury or pesticide nonperformance may result wholly or in part. Do not apply by air during periods of thermal inversion.

Apply during warm weather when weeds are in an active stage of growth. Adequate coverage is very important for effective weed control.

Limitations, Restrictions, and Exceptions


- This product can be used for selective control of Bahiagrass, Barnyardgrass, Chickweed, Smooth and Large Crabgrass, Dallisgrass, Nutsedge, Sandbur, and Wood Sorrel with little or no injury to well established, actively growing turfgrass. Mow turfgrass to a height of 1 to 1 1/2 inches before treatment. On new lawns, do not treat until after three mowings. Mix at a rate of 2 1/2 to 2 2/3 pints in 40 to 100 gallons of water for application to one acre. DO NOT apply more than 2 lbs. a.i. (2 2/3 pints) of this product per acre per application. For small areas, mix 1 fluid ounce (2 tablespoons) in 5 gallons of water for application to an area of 1,000 square feet. On established Bermuda and Zoysiagrass, up to 2 fluid ounces in 5 gallons of water per 1000 sq. ft. may be used. Application should be uniform and thorough to adequately wet all undesirable plants.

- Two or more repeat treatments at 14-day intervals may be necessary. Do not make more than three (3) applications per year. Make applications during warm weather when temperature is between 80 and 90°F. DO NOT water turf for at least 24 hours after application. Turfgrasses may be temporarily discolored. Bermudagrass, Bluegrass and Zoysiagrass have shown tolerance to properly applied MSMA. Injury may result if applied to Bentgrasses and Fescues. DO NOT apply to St. Augustinegrass, Carpetgrass, Centipedegrass, or to Dichondra lawns. DO NOT reseed until 2 weeks after last application.
