Abstract

The present invention relates to a herbicidal composition containing florasulam and metazafen, the composition is mainly characterized in that: the herbicidal composition contains 1-60% of active ingredients florasulam and 1-60% of metazachlor , Auxiliaries and other excipients, made of wettable powder, water dispersible granules, suspoemulsion, microemulsion, water emulsion, etc. The herbicidal composition of the present invention is used for controlling broad-leaved weeds and sedges in wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing florasulam and metazafen, which is used for preventing and treating broad-leaved weeds and sedges in wheat fields. Background technique [0002] In 1955, it was reported that Herbicide could increase the control effect of thatch quat on Limegrass. Later, with the further development of herbicide production and application, the mixed use of herbicides gradually developed. my country also pays more attention to the research on the mixed use of herbicides, which is widely regarded as one of the important measures for the rational use of herbicides. A series of herbicide mixtures have been developed and great progress has been made. [0003] Florasulam (florasulam), molecular formula: C 12 h 8 f 3 N 5 o 3 S, chemical name: 2',6'-difluoro-5-ethoxy-8-fluoro[1,2,4]triazol[1,5-c]pyrimidine-2-sulfonanilide. Flusulam is an inhibitor ...
