Abstract

There is disclosed a novel solvent-depletion process for making an avermectin/zein composition and the composition itself, which has excellent photostability and unexpected bioavailability to foliar-feeding insects. The process consists of depleting a dilute acidic, basic or alcoholic solvent from an emulsified solution of avermectin, zein, and dilute solvent.
