Abstract

The invention provides a weed removing composition containing flazasulfuron and oxyfluorfen. A weed killing spectrum can be enlarged, the dosage is reduced, the generation of insecticide resistance of weeds is delayed, and the labor intensity is reduced. The weed removing composition disclosed by the invention has synergistic interaction, can prevent and remove various weeds, and is high in safety.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing rimsulfuron-methyl and oxyfluorfen, which is used for controlling various crop weeds. Background technique [0002] With the change of farming system and the increasing demand of economic crops, especially during the long-term use of pesticides, crops have developed resistance, which greatly reduces the efficacy of pesticides. At the same time, the protection of crops from undesired vegetation which inhibits crop growth is a recurring problem in agriculture from time to time. To help address this problem, researchers in the field of synthetic chemistry have produced a variety of chemicals and chemical formulations that are effective in controlling the growth of such unwanted vegetation. Many types of chemical herbicides have been described in the literature, and many are in commercial use. [0003] Fluasulfuron-methyl belongs to the sulfonylurea he...
