Problems solved by technology

[0004] At present, abamectin preparation products are mainly granules, but when the dosage of abamectin granules is large, it is easy to cause phytotoxicity to crops, and the duration of drug effect is short, and the control effect of abamectin granules can no longer meet the requirements of modern Agricultural Production Requirements

Abstract

The invention relates to the technical field of pesticides and in particular relates to an abamectin slow-release granula and a preparation method thereof. The abamectin slow-release granula comprises abamectin, a carrier and a binder. The controlling effect of the abamectin slow-release granula provided by the invention is obviously higher than that of commercially available avermectin granules, the time of duration of pesticide effect is long, the abamectin slow-release granula has the ultra-efficient, harmfulless, residue-less, nuisanceless effects, and the like, the agricultural cost can be reduced, the preparation method is simple, and an application method is simple.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an abamectin sustained-release granule and a preparation method thereof. Background technique [0002] Avermectin, English name Avermectins, by Avermectin B 1a and Avermectin B 1b Mixed composition, CAS number is 71751-41-2, molecular formula is C 48 h 72 o 14 (B 1a )·C 47 h 70 o 14 (B 1b ), the structural formula is as shown in formula I (Avermectin B 1a : R=CH 2 CH 3 ; Avermectin B 1b : R=CH 3 ), it is a class of 16-membered macrolide compounds with insecticidal, acaricidal and nematicicidal activities first developed by Satoshi Omura of Kitasato University in Japan and Merck Company of the United States. It is fermented by Streptomyces avermitilis in Streptomyces griseus It is a high-efficiency, broad-spectrum antibiotic insecticide and acaricide, composed of a group of macrolide compounds, which has stomach poisoning and contact killing effects on mites and i...
