Abstract

The invention discloses an insecticidal composition comprising dicyclanil and a biological source. The composition comprises an active component A and an active component B. The active component A is selected from dicyclanil. The active component B is one compound selected from avermectin, emamectin benzoate, and ethyl spinosad. A weight ratio of the component A to the component B is 1:60-80:1. The composition provided by the invention has a synergetic effect against various pests harming agricultural production. With the composition, pesticide dose is reduced, pesticide residue on crop is reduced, and environment pollution is reduced. The composition is safe to human and livestock, and has good environment compatibility. With the composition, pest drug resistance is prevented.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing cyclopronil and biological sources 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] Molecular formula of abamectin: C 48 h 72 o 14 (B1a), which is a macrolide disaccharide compound, is a natural product isolated from soil microorganisms. It has contact and stomach toxicity to insects and mites, and has a weak fumigation effect without systemic effect. However, it has a strong penetrating effect on the leaves, can kill pests under the epidermis, has a long residual effect, and does not kill eggs. Its mechanism of action is different from general ins...
