Suspending agent containing diflufenican, flufenacet and pretilachlor

Abstract

The invention belongs to the technical field of pesticide and discloses a weeding suspending agent containing diflufenican, flufenacet and pretilachlor. According to the weeding suspending agent, the diflufenican, the flufenacet and the pretilachlor are utilized as main effective components; the weight ratio of the diflufenican to the flufenacet to the pretilachlor is (1 to 50) to (1 to 50) to (1 to 80), and the total mass percent content of the sum of the diflufenican, the flufenacet and the pretilachlor in the suspending agent is 1 to 80%. The suspending agent is further prepared from 0.2 to 2% of wetting agent, 0.3 to 3% of dispersing agent, 02 to 2% of thickening agent, 0.3 to 3% of stabilizer, 4 to 6% of antifreezing agent and the balance of deionized water to 100%. The invention further discloses application of the suspending agent in preventing and removing weeds in a winter wheat field. As herbicides are mixed and used, a weeding spectrum is expanded, a weeding effect is improved, and an effect of preventing gramineous weeds and broadleaf weeds is obvious. The suspending agent has the advantages of quick effect, long lasting period, delay in weeding herbicide drug resistance, weeding completeness, low residue, low toxicity, safety, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a three-component compound herbicide of diflufenamide, flufenacet and pretilachlor for controlling grass weeds and broad-leaved weeds in winter wheat fields. Background technique [0002] China's wheat planting area and output rank first in the world, and it is also the world's largest wheat producer and consumer. In China, wheat is planted all over the country, and the area of ​​winter wheat accounts for about 84% of the total area of ​​wheat. Weed damage has always been one of the limiting factors restricting the high yield and high quality of wheat fields in my country. Chemical weeding is the main means of weed control at present, and the use of chemical herbicides is also one of the important symbols of modern agriculture. The grass weeds in the winter wheat field are mainly brome, arvensis and bluegrass, and the broad-leaved weeds are mainly chrysalis, popo...

AI Technical Summary

Problems solved by technology

In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. At the same time, due to the variety of weeds, the use of a single variety can no longer effectively solve the weeds in wheat fields, and they will all show certain aspects. defect

At present, there are many kinds of herbicides on the market, and the application technology is also high. If there is a little carelessness in the application, problems such as critical damage and poor weeding effect will occur.
