A kind of high-efficiency compound pesticide composition containing dinotefuran

Abstract

A dinotefuran-containing efficient compound pesticide composition belongs to the technical field of pest chemical control, and is prepared by compounding dinotefuran and phenthoate in the mass ratio of dinotefuran to phenthoate of 1-30:1-50. The cumulative mass (weight sum) of dinotefuran and phenthoate is 1%to 70% of the total weight of the composition. The beneficial effects of the dinotefuran-containing efficient compound pesticide composition are that, (1) compared with a single agent, the composition can be obviously synergistic to rice fulgorid and striped rice borer, and can improve the control effect; (2) the composition can replace highly toxic pesticides, reduce the pesticide use amount, and effectively reduce ecological environment pollution and pesticide residues of rice; (3) the composition has quick-acting and long lasting characteristics; (4) the composition can inhibit rice fulgorid and striped rice borer resistance to drugs of the single agent; and (5) compared with the single agent, the cost of application can be reduced by combination of two kinds of single agents.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, and in particular relates to a compound combination of insecticides with synergistic effects on rice planthoppers and stem borers. technical background [0002] Rice is an important food crop in our country, and the safe production of rice is of great significance to the development of our national economy and the guarantee of food security. [0003] In recent years, rice planthoppers and borers have become a major threat to rice production in my country. In the mid-1990s, due to the large-scale promotion and application of imidacloprid, the high efficiency and long-acting characteristics of the drug greatly reduced the risk of outbreaks of rice planthoppers. drug resistance. At present, chemical control is still the main means to control the damage caused by rice planthoppers, and the selection of control drugs is directly related to the success or failure of control.

AI Technical Summary

Problems solved by technology

Chemicals such as dinotefuran, pymetrozine, thiamethoxam and nitenpyram have become the main pesticides for controlling rice planthoppers. The anti-efficacy is not ideal

[0004] Borer is a kind of endogenous rice pest, which causes dry heart and white ears of rice. In recent years, chlorantraniliprole and other chemicals produced by DuPont Company of the United States have been introduced to control rice borer and other Lepidoptera pests. Good, but the price of pesticides is high, and it is difficult to popularize and use them on a large scale, and the control effect on rice planthoppers is poor
