Abstract

The invention discloses a pesticide composition, containing an active component A and an active component B. The active component A is dicyclanil; the active component B is selected from chlopyrifos, DDVP and buprofezin; and the active component A and the active component B are in a weight ratio of 1:80-60:1. The composition provided by the invention has synergism on a plurality of insects harming agricultural production, reduces drug dose of pesticide, mitigate environmental pollution, is safe for human and livestock, has good compatibility and does not cause resistance of the insects.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a pesticide composition on crop pests. Background technique [0002] Dicyclanil chemical name: 4,6-diamino-2-cyclopropylaminopyrimidine-5-carbonitrile, molecular formula: C 8 h 10 N 6 . Cyclopronil interferes with insect shedding and, when absorbed by the insect's reproductive system, prevents larvae from pupating or becoming worms. [0003] Chlorpyrifos (Chlorpyrifos) chemical name: O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) phosphorothioate, molecular formula: C 9 h 11 Cl 3 NO 3 PS. Chlorpyrifos is a cholinesterase inhibitor, the residual period on the leaves is not long, but the residual period in the soil is longer, it has good control effect on underground pests, and is sensitive to tobacco. [0004] Dichlorvos (Dichlorvos) chemical name: O, O-dimethyl-O-(2,2-dichloro) vinyl phosphate, molecular formula: C 4 h 7 Cl 2 o 4 p. Dichlorvos is an i...
