Problems solved by technology

However, methylsulfuron-methyl has relatively high requirements on pesticide application technology. It cannot be applied after wheat jointing or plant height is 13cm. The safety interval between pesticide application and subsequent crops is as long as 90 days. Farmers have caused irreparable losses, and it has also seriously affected the reputation of manufacturers

Abstract

The invention discloses a weeding composition for improving the safety of mesosulfuron-methyl. The weeding composition comprises effective components mesosulfuron-methyl and a safener 5-aminolevulinicacid, and the weight ratio of mesosulfuron-methyl to 5-aminolevulinic acid is 1: 1-1: 100. 5-aminolevulinic acid is added into the weeding composition, so that the safety of mesosulfuron-methyl to crops is improved, and phytotoxicity is reduced.

Description

technical field [0001] The invention relates to a herbicidal composition for preventing and controlling weeds in wheat fields, in particular to a safe herbicidal composition containing methylsulfuron-methyl. Background technique [0002] Sulfonylurea herbicides are one of the most important herbicides in the world. Mesosulfuron-methyl is a sulfonylurea herbicide developed by Bayer AG in 2002. Methsulfuron-methyl 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 blocked branched-chain amino acid synthesis, thereby inhibiting cell division and causing sensitivity Plants die. Its control targets are mainly annual gramineous weeds such as A. chinensis, wild oats, bluegrass, brome, and barley. Under normal circumstances, the absorption of sensitive weeds reaches the peak 2-4 hours after spraying and...
