A kind of synergistic herbicidal composition containing propargyl fluoride and diflufenamide and its application

Abstract

The invention discloses a synergic weeding composite adopting allylene benfluralin and diflufenican as active ingredients and application thereof and belongs to the field of compounding of herbicides.The weight percentage of effective components including allylene benfluralin and diflufenican in the synergic weeding composite is 1:50-1:50, wherein the optimal weight percentage is 1:20-1:20. The effective components including allylene benfluralin and diflufenican account for 1-90% of the total amount of the composite, wherein the effective components optimally account for 5-80% of the total amount. The weeding composite can effectively prevent poaceae and broad-leaf weeds with the resistance on ALS or ACCase inhibitor type herbicides, the synergic effect is significant, the safety is high,and stubble residues are avoided.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, and in particular relates to a synergistic herbicidal composition with diflufenamid and diflufenamid as active ingredients and an application thereof. Background technique [0002] At present, chemical weeding is the most economical and effective means in the production of winter wheat in my country, among which acetolactate synthase (ALS) inhibitor herbicides and acetyl coenzyme A carboxylase (ACCase) inhibitor herbicides are the two main herbicides in my country's wheat fields. Wide variety of herbicides. However, with the long-term and large-scale application of herbicides, weeds in my country's wheat fields, including A. These two types of herbicides have produced severe resistance, which seriously restricts the high and stable yield of wheat in my country. Screening alternative agents for other targets and mixing them has become one of the effective means for controlling resistant weeds. ...
