Embodiment 1

[0037] Embodiment 1: the composition of avermectin azole and fenfencarb

[0038] Table 1. Combined synergistic effect of the composition on Tetranychus cinnabarinus

[0039]

[0040] It can be known from Table 1 that the composition provided by the application has a co-toxicity coefficient greater than 120 in the weight ratio of abamectin and pyrafefenacil in the range of 1 to 50:50 to 1, and all show increased effects on Tetranychus cinnabarinus. effect. The mixing of ZJ10665 and spirotetramat is reasonable and feasible.

Abstract

The invention discloses a composition containing abamectin and a farm chemical named as Chinese characters 'Zuomimanjing' in a weight ratio of (1-50): (50-1). The composition provided by the inventionhas the characteristics of high efficiency, low toxicity and long lasting period, and is suitable for preventing and controlling mite pests.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a composition containing abamectin and pyrafencarb. Background technique [0002] Agricultural pest mites are small in size, fast in reproduction, strong in adaptability, and easy to develop resistance. They mainly harm leaves, young shoots, flower buds and fruits. When the number of pest mites increases sharply, it will cause plant defoliation, growth inhibition or even death. One of the most difficult pests to control. And long-term use of a chemical agent is easy to make the harmful mites develop resistance. [0003] For example, avermectin is a sixteen-membered macrolide compound, and its mechanism of action is to interfere with the neurophysiological activities of insects and harmful mites to cause their death. It has stomach poisoning and contact killing effects on insects and mites, and has good Its broad-spectrum and quick-acting properties can show high biological activity agai...
