INSECTICIDAL COMPOSITIONS, AND PREPARATION AND USE THEREOF

摘要

An improved insecticidal particulate composition is a free-flowing composition comprising 1-50% by weight of methomyl impregnated in 10-98% by weight of a water-insoluble polymer which is soluble in an organic solvent, has an inherent viscosity of at least 0.2 and is capable of releasing methomyl at a rate such that said composition exhibits an undiminished initial activity, an enhanced residual activity and reduced phytotoxic damage to cotton plants relative to solid methomyl. The composition may be made by precipitating the components from solution by comingling with a non-solvent under conditions of high shear.
