摘要: Granular pesticides have been defined as solid formulations of discrete particles between the size ranges 8 to 60 mesh U. S. sieve size, that is 2.38 0.25 mm. diameter (Sferra 1962), although tendency raise lower limit 40 mesh, or 0.42 (U.S.D.A. 1962). The are composed a base, usually an inert mineral vegetable carrier, impregnated fused with chemical toxicant.This released from granule both in its intact and it disintegrates, giving controlled release.
