Pesticide composition containing isoproturon, pretilachlor and bensulfuron methyl and application of pesticide composition

Abstract

The invention discloses a pesticide composition containing isoproturon, pretilachlor and bensulfuron methyl and application of the pesticide composition. The pesticide composition comprises the isoproturon, the pretilachlor and the bensulfuron methyl which serve as active components; the mass ratio of the isoproturon to the pretilachlor to the bensulfuron methyl is (10-50):(10-50):(0.5-10). The pesticide composition achieves an obvious synergistic effect within the proportion range, so that the use dosage of pesticides is reduced, the drug use frequency is reduced, the drug use cost is lowered, and an adverse effect of the pesticides on the ecological environment is alleviated; the weeding spectrum is expanded; due to primary drug use, various weed problems are solved, and the shortcoming and the boundedness which are caused by single-dosage use are avoided; the service life of a medicine is prolonged; the pesticide composition has an important significance for comprehensive treatment on weed resistance; the pesticide effect achieving speed is high, the lasting period is long, and the use cost is low; the pesticide composition can be used for preventing and controlling grassy weeds, broad-leaf weeds and cyperaceae weeds in paddy fields or grassy weeds and broad-leaf weeds in wheat paddocks.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a compound containing isoproturon and acetaminophen used for preventing grass weeds, broad-leaved weeds and Cyperaceae weeds in rice fields or grass weeds and broad-leaved weeds in wheat fields. Pesticide composition of oxachlor and bensulfuron-methyl. Background technique [0002] According to statistics, the world's grain production loses 14% every year due to diseases, insects, and weeds, of which the loss caused by weeds is about 11%. Weed damage is a key factor restricting crop production. The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, sales of herbicides have increased year by year, accounting for an increasing proportion of pesticide sales, and the application area has expanded year by year. Rice is the crop with the largest consumption, the largest planting area, the largest total output and the highest per unit...

AI Technical Summary

Problems solved by technology

[0006] Purpose of the invention: In view of the problems in the prior art of producing resistance to farmland weeds, poor control effect of single use, and difficulty in effectively controlling the damage of weeds during the entire growth period of rice with one use, the purpose of the present invention is to provide an isotropic The pesticide composition of propachlor, pretilachlor and bensulfuron-methyl makes it highly efficient, broad-spectrum, environmentally friendly, and beneficial to the comprehensive management of weeds in paddy fields, etc.
