Sulfonic carbamide and fluoroglycofen-ethyl mixed herbicides

Abstract

A herbicide is prepared from one of tribenuron-methyl, triasulfuron and bensulfuron-methyl, and fluoroglycofen-ethyl (1-50 wt.%) in ratio of 1:(0.625-2) through mixing. Its advantages are broad spectrum, low dosage, no environmental pollution, and high effect.

Description

technical field [0001] The invention belongs to chemical herbicides, in particular to a compounded chemical herbicide of sulfonylureas and acifluorfen. Background technique [0002] Weeds are one of the important factors affecting the growth of crops and agricultural harvest, so people have racked their brains to remove weeds in the field. The invention of chemical herbicides has greatly improved the weeding effect and had an immeasurable effect on agricultural production. Chemical herbicides have broad-spectrum and high-efficiency characteristics, and sulfonylurea herbicides are the most widely used among many herbicides. They have broad-spectrum and high-efficiency characteristics, and are deeply favored by farmers. Commonly used among sulfonylurea herbicides are tribenuron-methyl herbicide with tribenuron-methyl as the main ingredient, tribesulfuron-methyl herbicide with tribenuron-methyl as the main ingredient, and benzsulfuron-methyl as the main ingredient. Sulfururon...

AI Technical Summary

Problems solved by technology

Among the sulfonylurea herbicides commonly used are tribenuron-methyl herbicide with tribenuron-methyl as the main ingredient, tribesulfuron-methyl herbicide with tribenuron-methyl as the main ingredient, and benzsulfuron-methyl as the main ingredient. Sulfururon herbicide, because this kind of herbicide has a single component and uses systemic conduction as the herbicidal mechanism, on the one hand, it is not effective in removing older and broad-leaved weeds. On the other hand, the action cycle is long and the effect is slow, which in turn affects weeding As a result, it not only increases the burden on farmers, but also affects the agricultural harvest

However, acifluorfen has a good effect on controlling older and broad-leaved weeds, but its application range and functions have not been recognized by people.
