Problems solved by technology

[0009] Although the prior art discloses the compound of pyriproxyfen and thiamethoxam, the research in this area only stays at the synergistic level, that is, through indoor or field experiments, the toxicity or toxicity of the composition relative to a single agent is determined. Control effect, without further research or improvement, the existing technology has never paid attention to or paid attention to the effective utilization rate of the agent after application, such as the amount of drug that penetrates the surface of the insect, which causes unnecessary waste

Abstract

The invention discloses a mixture prepared by blending an agricultural synergist with a compound of pyriproxyfen and thiamethoxam as well as preparation and application of the mixture. In the mixture, the agricultural synergist is N-380; the compound of pyriproxyfen and thiamethoxam is an insecticide; and a weight ratio of the agricultural synergist to the insecticide is 1: (0.1-50). The invention also relates to use of the agricultural synergist for increasing penetration of insecticide into insect body surfaces, and application of the mixture for preventing and controlling agricultural pests.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a mixture of an agricultural synergist mixed with pyriproxyfen and thiamethoxam and its preparation and application. Background technique [0002] my country is a large agricultural country, and the use of pesticides is inseparable from the actual agricultural production. However, with the prolongation of the history of chemical control of agricultural pests and the influence of factors such as unscientific use of pesticides, it follows that agricultural pests resist The pests are becoming more and more resistant, and the types of pests that produce resistance continue to increase, which is one of the agricultural problems that need to be solved urgently. [0003] Pyriproxyfen (pyriproxyfen) is a class of insecticides of juvenile hormones developed by Sumitomo Chemical Co., Ltd., which belongs to chitin synthesis inhibitors, and can effectively inhibit the developmental metamorphosis of...
