agriculture, more particularly metal phosphide-based pesticidal agent. SUBSTANCE: pesticidal agent comprises metal phosphide as such or in the for of preparation, and hydroscopic agent and is enclosed into moisture-proof packing. Hydroscopic agent is zeolite with pore diameter of 4-10 A and has moisture of 0.1-1.5 %, or mixture of zeolites of above-indicated characteristic, metal phosphite to zeolite being used at weight ratio from 1: 0.01 to 1:1 zeolite has generally particle size of 0.001-5 mm. Dangerous concentration of phosphine and self-inflammation induced by it are thus avoided in packing. This enables one to handle safety with pesticidal agent. EFFECT: improved properties of the pesticidal agent. 2 cl, 8 tbl
