Abstract
A stable premixture composition which remains soluble or emulsifiable prior to mixing with pesticides includes an aliphatic solvent, an emulsifier, a phosphate ester water conditioner and/or a polyacrylate dispersant, an antifoam agent and a polyacrylamide drift reduction agent. A preferred formulation includes a petroleum distillate, Tallowamine, Good-Rite K-752, a silicone foam control agent, water and a polyacrylimatePolytex 363. A preferred technique for application to agricultural acreage at a rate of 10 gallons per acre, involves the addition of 3 quarts of the composition of the present invention to 200 gallons of water, followed by the addition of 3 quarts of Roundup.TM. or other weak acid herbicide (such as, for example, Touchdown.RTM., 2-4,D's, sulfonyl urea, imizazolone), followed by water to 300 gallons.
