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

POSTEMERGENT APPLICATION ON COTTON USING GROUND OR AIRCRAFT EQUIPMENT AS AN OVER-THE-TOP BROADCAST SPRAY when cotton is 3 inches high until early first square stage as a salvage operation. Mix at the rate of 1 to 1 1/4 pints of this product in 40 gallons of water for ground equipment or in 5 to 10 gallons of water for aircraft application and apply using a properly calibrated sprayer to one acre. DO NOT apply more than 1.0 lb. a.i. (1 1/4 pints) of this product per acre per application. A second or repeat application, if needed, should be timed 1 to 3 weeks after the first application. Apply only as a salvage operation. Apply only to healthy, rapidly growing cotton, 3 inches high, but no later than 6 inches high or early square, whichever occurs first. Preference should be given to directed sprays. In order to minimize injury, the second application should be made as a directed spray when possible. DO NOT make more than two (2) applications total of either DSMA or MSMA (or a combination) per season.
