Design and release profile of timed-release coated granules of systemic insecticide

Abstract

A novel timed-release system with a certain lag time (or release-suppression time) of pesticides has been developed using coated water-swelling granules including a systemic insecticide. The lag time and release profile of the insecticide are controlled by the polymer composition of the membrane that contains low-density polyethylene (LDPE) and talc, and by the core granule composition of the water-swelling material.
