A kind of herbicidal composition containing fenflumezone

Abstract

The invention relates to a weeding composition containing topramezone. The composition comprises two active components including mesosulfuron and topramezone; the weight ratio of the two active components ranges from (1:60) to (60:1). The weeding composition is wide in weeding spectrum, obvious in weeding effect and safe to crops.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing mesosulfuron-methyl and oxaflumezone. Background technique [0002] Mesosulfuron-methyl chemical name: methyl-2[3-(4,6-=methoxypyrimidin-2-yl)-ureidosulfonyl]-4-methylsulfonylaminobenzidine Ester, a sulfonylurea herbicide, is mainly absorbed through the stems and leaves of plants, conducted through the phloem and xylem, and a small amount is absorbed through the soil, inhibiting the activity of acetolactate synthase in sensitive plants, resulting in the synthesis of branched-chain aminofacic acid blocked, thereby inhibiting cell division and leading to the death of sensitive plants. It can be used to control wheatgrass, wild oats, clubhead grass, bluegrass, hard grass, soda, ryegrass, poisonous wheat, brome, candle grass, chrysanthemum, chrysanthemum, wheatgrass, and shepherd's purse in wheat fields , Boniang Artemisia, Beef Chickweed, S...

AI Technical Summary

Problems solved by technology

In recent years, the reasonable selection of herbicides in wheat fields has become an important technical link to ensure the safe production of wheat. However, due to improper selection of herbicides or inadequate use of technology, the control effect is not ideal or the phenomenon of phytotoxicity occurs frequently.

At present, there are few herbicide varieties that can control grass weeds and broad-leaved weeds at the same time. Usually, after people use a certain herbicide to control grass weeds, broad-leaved weeds are also called the dominant population of weeds. Or after controlling broad-leaved weeds, gramineous weeds have become the dominant population of weeds again, so it is necessary to require people to repeatedly use medicines to prevent and control various weeds, which wastes a lot of manpower and material resources. The pollution of the environment and the excessive pesticide residues in the video have brought direct harm to human health
