  • Reduced spray drift methomyl compositions
    Patent number: 3934005
    Abstract: Compositions of stable, conceentrated, liquid methomyl formulations comprising high-molecular-weight polyoxyethylene, methomyl, and certain organic solvent systems which, when diluted with water for spray-tank use, reduce spray drift.BACKGROUND OF THE INVENTIONThis invention relates to an improved method of spraying of solutions containing S-methyl-n-[(methylcarbamoyl)oxy]thioacetimidate (methomyl) insecticides. Methomyl and methomyl insecticides are described in U.S. Pat. No. 3,576,834. Methomyl insecticides are extremely effective against a wide variety of important crop insects by providing economic control at use rates of 0.25 pound or less of methomyl per acre. Liquid formulations containing high concentrations of methomyl dissolved in organic solvents are the subject of copending applications Ser. No. 317,802, filed Dec. 22, 1972, and Ser. No. 359,503, filed May 11, 1973.Such liquid formulations are very convenient for the user.
