Insecticide compounding with buprofezin and pymtrozine as well as method for preventing and controlling pest thereof

Abstract

The invention belongs to the technical field of pesticide, and relates to a mixed insecticide of Buprofezin and Pymetrozine and the prevention and treatment of pests using the insecticide. The active ingredients in the insecticide are the Buprofezin and the Pymetrozine. The weight ratio of the Buprofezin and the Pymetrozine is 10:1 to 1:10. The insecticide is wettable powder, the weight percentage of the each ingredient of the insecticide are: 1 to 30 percent of the Buprofezin, 30 to 1 percent of the Pymetrozine, 5 to 15 percent of the auxiliary agent of pesticide wettable powder and the rest of kaolinite. The invention has relatively good prevention and treatment effect on pests such as plant hopper and aphid, etc and little affect to environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compound insecticide of buprofezin and pymetrozine and a method for controlling pests. Background technique [0002] There are mainly three kinds of planthoppers that harm rice in my country: brown planthopper, brown planthopper, and white-backed planthopper. In my country, brown planthopper is the most harmful. In the Jianghuai rice region, there are 2-5 generations of brown planthopper and 4-5 generations of white-backed planthopper. SBPH generally overwinter locally and only migrates short distances. There are 5-6 generations in Jiangsu and Zhejiang all the year round, but the 1-2 generations are the most harmful. In the control of rice planthoppers in my country, in the 1960s to 1980s, insecticides such as organophosphorus, organochlorine, and organic nitrogen were sprayed at the peak of nymphs; At the end of the 1990s, imidacloprid was used to control rice planthoppers, ...

AI Technical Summary

Problems solved by technology

In the control of rice planthoppers in my country, in the 1960s to 1980s, insecticides such as organophosphorus, organochlorine, and organic nitrogen were sprayed at the peak of nymphs; At the end of the 1990s, imidacloprid was used to control rice planthoppers, but due to continuous use, a certain degree of drug resistance was produced in production, and the control effect declined. Borth, the agent has a stimulating effect on the reproduction of rice planthoppers, making rice planthoppers (especially brown planthoppers and brown planthoppers) a particularly large occurrence in recent years

At present, the control of rice planthoppers in my country mainly includes buprofezin, imidacloprid, fipronil, dichlorvos, trichlorfon, etc. Some of these agents have been resistant to insecticides, and some have strong resistance to natural enemies in rice fields. Some of them are unsafe to use, and it is easy to cause poisoning of the sprayers when used in paddy fields, which has a great impact on the environment.
