Herbicide for wheat paddock

Abstract

The invention discloses an herbicide for a wheat paddock. The active ingredients of the herbicide comprise flucarbazone-sodium, mesosulfuron, dicamba and clodinafop-propargyl; the weight part ratio of flucarbazone-sodium to mesosulfuron to dicamba to clodinafop-propargyl is (1-30): (1-30): (1-20): (1-10); the herbicide is creaming agent, wettable powder, water dispersing agent, suspending agent or soluble concentrate. The four active ingredients of the herbicide have excellent synergistic interaction effect in a certain matching scope. Compared with a single weeding agent, the herbicide has the advantages that the weeding activity and weeding effect are greatly increased, the dosage is reduced, the damage of herbicide to wheat is effectively reduced, the safety is high, the afterreap crop is not influenced, the influence on ecological environment is small, the benefits of farmers are protected, and meanwhile, the labor intensity and working frequency of the farmers are obviously reduced and the herbicide is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a herbicide for wheat fields. Background technique [0002] Wheat is the most important food crop in northern my country. It is related to the national economy and people's livelihood and the country's food security. It is mainly winter wheat, accounting for about 90%. Weeds in wheat fields affect the growth of wheat. According to the national weed census, there are more than 200 kinds of weeds in my country's wheat fields, the weed damage accounts for more than 30% of the wheat planting area, and the loss accounts for about 15% of the total wheat output, reaching 10 billion kilograms. There are about 30 kinds of main weeds in wheat, such as kangaroo, Japanese kangaroo, brome, bluegrass, hard grass, club head grass, miscanthus, pig's calamity, beef chickweed, mother-in-law, broken rice, sorrel Polygonum vulgaris, Nesglossia, Dacha, Wild Rape, Artemi...

AI Technical Summary

Problems solved by technology

[0003] With the long-term and large-scale promotion and application of herbicides, the problems of weed resistance, population succession and phytotoxicity in chemical weed control in farmland are becoming more and more serious, seriously affecting the high yield and harvest of wheat and the safety of subsequent crops

At present, the commonly used stem and leaf herbicides in wheat fields are only effective in controlling broad-leaved grasses, and have poor control effects on gramineous weeds. The use of pesticides has caused great resistance in weeds, and weeds in wheat fields are becoming more and more difficult to kill
