Problems solved by technology

In addition, the applicant found through retrieval that there are no detailed reports on the mixing of beta-cypermethrin and hexaflumuron to prevent and control sanitary pests at home and abroad. To prevent and control fish parasites, but because it is different from the pesticide composition used in the present application in terms of active ingredients, control objects, mixing ratio, etc., and it does not give any mixed synergistic test data

Abstract

The present invention relates to a kind of pesticide composition, more specifically relate to a kind of pesticide composition comprising effective amount of beta-cypermethrin and hexaflumuron, wherein the weight ratio of beta-cypermethrin and hexaflumuron is preferably 1:1~9 :1, more preferably 7:3 to 8:2. The pesticide composition is particularly suitable for controlling sanitary pests such as houseflies and cockroaches.

Description

technical field [0001] The invention relates to a synergistic pesticide composition, in particular to a synergistic pesticide composition comprising beta-cypermethrin and hexaflumuron. Background technique [0002] Alphamethrin is a high-efficiency, broad-spectrum pyrethroid insecticide. The drug is a nerve axon conduction inhibitor, which belongs to the nerve agent and has a rapid action. It has good control effects on various pests on wheat, cotton, vegetables, fruits, soybeans and other crops, and has an ovicidal effect on some pests. . Beta-cypermethrin has a simple synthesis process and low cost, so it is widely used in the control of agricultural pests. However, beta-cypermethrin also has a very obvious shortcoming, that is, the duration of efficacy is relatively short. In practical applications, due to the high frequency of application, pest resistance is generated and the efficacy of the drug decreases. [0003] Hexafluron is a new type of benzoylurea insecticide,...
