Multi-element mixed composition water dispersible granule

Abstract

The invention provides a multi-element mixed composition water dispersible granule, 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 components are mixed evenly and pulverized by ultrafine airflow to obtain ultrafine powder for later use, then are subjected to high-speed mixing valve granulation and dried at 50-80 DEG C, and the water dispersible granule is obtained after sieving, wherein the composition with the mixture ratio of 7:4:70 has the best efficacy, the weed control map can be effectively expanded and the herbicide herbicide killing activity can be improved, 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 water-dispersible granule of a multi-component compounding 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...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of scientific use of herbicides by farmers in non-cultivated land in my country, a single-dose herbicide is often applied to one or a limited number of concentrated weed species, and the scope of application is narrow. During the use of a single-dose herbicide, it is easy to cause weeds to appear resistance, which reduces the service life of pesticides and greatly reduces the weeding effect, but the pollution damage to the environment has not been reduced
