Abstract

The invention relates to a herbicide emulsifiable concentrate preparation containing pentoxazone and amidosulfuron. The active ingredients, pentoxazone and amidosulfuron, in the herbicide are mutually mixed to provide a broad weed control spectrum. The active ingredients in the herbicide are matched to play a very good synergy role in a certain range, so that the herbicide is higher in control effect than a single agent, and the drug property maintenance time is long; the herbicide is extremely safe to cereal crops.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a herbicide emulsifiable concentrate preparation containing cyclopentazone and rimsulfuron-methyl. Background technique [0002] Cyclopentazone, chemical name 3-(4-Chloro-5-cyclopentyloxy-2-fluorophenyl)-5-isopropylene-1,3-oxazoline-2,4-dione , the structural formula , belonging to oxazolones, the pure product is a colorless, odorless powdery solid; melting point 104°C; density 1.418 (25°C); vapor pressure <1.11×10-5Pa (25°C). Partition coefficient LogP=0.67; solubility in water is 0.216 mg / l (25°C); stable to light, heat and acid, unstable to alkali. It is mainly used to control barnyard grass and annual weeds. Using p-fluorophenol as the starting material, through chlorination, esterification and nitration to obtain intermediate substituted nitrobenzene; through hydrolysis to obtain intermediate substituted phenol potassium salt; and then through etherification and reduction to...
