Weeding composition containing methiopyrisulfuron and pyribambenz-propyl

Abstract

The invention relates to a weeding composition. Active ingredients of the weeding composition are methiopyrisulfuron and pyribambenz-propyl, and the weight ratio of the methiopyrisulfuron to the pyribambenz-propyl is 100: 1 to 1: 100. The invention also relates to a method of the weeding composition for preventing undesirable plants and a use of the weeding composition in preventing the undesirable plants.

Description

technical field

[0001] The invention relates to the field of agriculture, in particular to a herbicidal composition, in particular to a herbicidal composition containing thiosulfuron-methyl and acetofen. Background technique

[0002] The prevention and control of agricultural weeds and the resistance of agricultural weeds have always been the most concerned and important issues in agricultural production.

[0003] Pyribambenz-propyl (CAS RN.420138-40-5) is a new type of herbicide belonging to the pyrimidine class. The pure product is a white solid with a melting point of 96-97°C. It is insoluble in water and easily soluble in dichloromethane and acetone. and other organic solvents. Propoxyfen is mainly used to control annual grass weeds and some broad-leaved weeds.

[0004] Methiopyrisulfuron (CAS RN.441050-97-1) is a sulfonylurea herbicide, the pure product is a white solid with a melting point of 184-186°C, and it is mainly used in wheat fields to control various broad-l...
