摘要：
A granular agrochemical composition is disclosed including a granular corematerial having a water soluble portion with a first coating layer applied onthe surface of the core material and a second coating layer applied on thesurface of the first coating layer. The first coating layer includes a waxcomposition having a biologically active ingredient incorporated therein andthe second coating layer includes a polymeric composition. The granularagrochemical composition exhibits a controlled rate of release of thebiologically active ingredient therefrom over a period greater than about 30days from the date of initial exposure of the granular composition to moisturewhereby essentially all of the biologically active ingredient incorporated inthe wax material of the first coating layer is released from the granularcomposition before the water soluble portion of the granular core material isreleased from the granular composition.
