Local conditions and application method may affect performance of this product. User should consult local extension service, agricultural experiment station, or university weed specialists, and state regulatory agencies for recommendations in your area.
Best results are obtained when product is applied to young succulent weeds that are actively growing. Application rates lower than recommended will not be satisfactory on susceptible annual weeds. For perennial weeds, the higher recommended rates should be used. Some plants and weeds, especially woody varieties, are hard to control and may require repeat applications. Application rates should be 1 to 5 gallons of total spray by air or 5 to 25 gallons by ground equipment unless otherwise directed. In either case, use the same amount of SINKERBALL per acre. SINKERBALL should not be allowed to come into contact with susceptible desirable species. If stored below freezing, it may be necessary to warm product to 40ºF and agitate before using. This does not affect the efficiency of the product. Spray equipment used to apply SINKERBALL or other products containing 2,4-D should not be used for any other purpose until thoroughly cleaned with a suitable chemical cleaner.
