摘要： Disclosed is an insecticidal composition comprising by weight based on the total weight of the composition: (a) from about 0.25 to about 25% of one or more anthranilic diamide insecticides; (b) from about 2.5 to about 25% of a poly(lactic acid) polymer component having a water dispersability of at least about 5% by weight at 20° C. and an average molecular weight ranging from about 700 to about 4,000 daltons; wherein the ratio of component (b) to component (a) is about 1:1 to about 1:10 by weight; and (c) from about 20 to about 50% of a composition comprising either (i) a poly(lactide-co-glycolide) copolymer and a methyl poly(ethylene glycol) copolymer, or (ii) an acrylate/methacrylate-based polymer or copolymer and a methyl poly(ethylene glycol) copolymer; wherein the methyl poly(ethylene glycol) copolymer has a water solubility of at least about 5% by weight at 20° C., a hydrophilic-lipophilic balance value of at least about 7, and an average molecular weight ranging from 12,000 to 65,000, and further wherein the ratio of the poly(lactide-co-glycolide) or the acrylate/methacrylate-based polymer or copolymer, to the methyl poly(ethylene glycol) is about 1:1 to about 4:1 by weight and the ratio of component (c) to component (b) is about 2:1 to about 9:1 by weight. Also disclosed is a geotropic propagule coated with the insecticidal composition. Further disclosed is a liquid composition comprising the insecticidal composition, and a method for protecting a geotropic propagule and plant derived therefrom from a phytophagous insect pest.
