Problems solved by technology

[0005] The weeds in the wheat field are complex, grass weeds, broad-leaved weeds and sedge weeds and other types of weeds are mixed. The use of a single species of herbicide cannot completely solve the problem of weed damage in the wheat field. Defects and limitations, such as poor actual control effect on weeds in wheat fields, weeds are prone to drug resistance, etc.

Abstract

The invention provides a herbicidal composition containing flupyrsulfuron-methyl and application of the composition. The herbicidal composition contains herbicidal active components including fenoxaprop-p-ethyl, flupyrsulfuron-methyl and carfentrazone-ethyl, and a safener, wherein fenoxaprop-p-ethyl accounts for 1-40% of the total weight of the herbicidal composition, flupyrsulfuron-methyl accounts for 1-25% of the total weight of the herbicidal composition, carfentrazone-ethyl accounts for 1-25% of the total weight of the herbicidal composition, and the safener accounts for 10-20% of the total weight of the herbicidal composition. The herbicidal composition is long in persistence, the active components have a synergistic or additive function. Compared with single preparations, the composition widens a herbicidal spectrum, improves the prevention and control effects, reduces herbicide consumption, reduces herbicide application cost, delays development of weed drug resistance, and is beneficial to comprehensive treatment of wheat field weeds.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and in particular relates to a herbicidal composition containing rimsulfuron-methyl and its application. Background technique [0002] Fenoxaprop-p-ethyl is a low-toxic heteroepoxyphenoxypropionic acid herbicide developed by Agfor, and it is a selective systemic conduction post-emergence stem and leaf treatment agent. Its mechanism of action is an inhibitor of acetyl-CoA carboxylase. Fenoxaprop-ethyl is suitable for controlling monocotyledonous weeds in dicotyledonous crops such as soybeans, peanuts, rapeseed, cotton, and broad-leaved vegetables. After adding a safener, it can be used to control gramineous weeds in wheat fields. It has good control effect on vicious gramineous weeds such as Niang, Japanese Kan Mai Niang, wild oats, hard grass, barnyardgrass, foxtail and sage. [0003] Fluoxazone-methyl is a sulfonylurea herbicide developed by DuPont. Its mechanism of action is an inhibit...
