Green low-toxicity synthetic polymer herbicide composition

Abstract

The invention discloses a green low-toxicity synthetic polymer herbicide composition. The composition comprises effective components of flumioxazin, fluoroglycofen-ethyl and glufosinate-ammonium, the mass percentage ratio of the flumioxazin to the fluoroglycofen-ethyl to the glufosinate-ammonium is (2-10):(1-6):(60-75), and the composition further comprises a wetting dispersant, a disintegrating agent, an adhesive and a carrier. The composition is prepared by the following steps: uniformly mixing the components according to a ratio of 7:4:70, performing ultrafine jet milling to obtain ultrafine powder for later use, performing granulating by using a high-speed mixing valve, performing drying at 50-80 DEG C, and performing screening to obtain water dispersible granules. The components are mixed according to a ratio of 7:4:70 so as to achieve best pesticide effect; the composition can effectively expand the weed control map, and improves the herbicidal activity of herbicides; and meanwhile, the dosage of the herbicide is remarkably reduced, the resistance of weeds to a single weeding agent is reduced, the resistance of the weeds to the single weeding agent is delayed, the control effect on resistant weeds is improved, the service life of the agent is prolonged, and the environmental pressure is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a green and low-toxic synthetic polymer herbicide composition. Background technique [0002] Pesticides are one of the important means of agricultural production, and modern agriculture is inseparable from pesticides. Because of their vigorous vitality, weeds are easy to compete with crops for water, nutrients, soil and space. They are the hosts of crop diseases and insect pests, spread diseases and insect pests, degrade the yield and quality of crops, increase the harmfulness, and increase management labor and production. Cost; With the acceleration of my country's urbanization process, a large number of rural laborers have transferred to cities, and there is a serious shortage of high-quality laborers in rural areas. Compared with insecticides and fungicides, herbicides are selective control of weeds between crops and weeds. Grass. [0003] Glufosinate-ammonium is a contact-...

AI Technical Summary

Problems solved by technology

[0004] A large number of compounds with herbicidal activity have been found in the prior art. These compounds are currently sold and used as herbicides. In order to ensure the herbicide's herbicide effect and broad-spectrum herbicide performance, the herbicides used are often highly toxic and harmful to the environment. and crops are more threatening, and even cause food toxicity residues, which are harmful to people's health
