Mixed weedicide containing clodinafop-propargyl and acetochlor

Abstract

The invention discloses a mixed weedicide containing clodinafop-propargyl and acetochlor. The effective components of the mixed weedicide comprise clodinafop-propargyl and acetochlor at a mass ratio of 1:(0.6-25), preferably 1:(3-10). Compared with the weedicide in the prior art, the mixed weedicide disclosed by the invention has the following prominent advantages that: the weeding activity is high; the weeding spectrum is broad; the durability is long; after clodinafop-propargyl and acetochlor are mixed with a broad-leaf weedicide, the actions are complementary, the weeding spectrum is broader, and the weeding effect is better; the applicable weed age is wide: clodinafop-propargyl is a stem leaf treating agent, and acetochlor is a soil treating agent, thus after clodinafop-propargyl and acetochlor are mixed, weeds in two breeding periods can be removed at the same time; the weed resistance is delayed; and the safety is high. The mixed weedicide disclosed by the invention can be applied in preparation of the weedicide for weeding after wheat field seedlings, and can especially be applied in removal of various gramineae and broad-leaf weeds in wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a herbicide, in particular to a mixed herbicide containing clodinafop-propargyl and acetochlor. Background technique [0002] Wheat is one of the most important grain resources in the world, and its output ranks second only to rice. It is not only the main food resource for human beings, but also an important industrial raw material. However, the harm of weeds in wheat fields has always been an important factor that affects the quality and efficiency of wheat. At present, the main weeds that endanger wheat fields are: Japanese kangaroo, Chinese kanko, wild oats, bluegrass, chrysalis, chickweed , wild geranium, mother-in-law, large and small nest vegetables, shepherd's purse, lacquer, small thorns, etc. With the recent changes in cropping systems and cultivation management, some new weed biological types and some non-agricultural weeds have developed rapidly in wheat fields, some...

AI Technical Summary

Problems solved by technology

[0010] At present, herbicides in wheat fields are limited by crop safety and herbicide herbicide spectrum. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in wheat fields. Moreover, some herbicides have too long field duration , Excessive dosage or uneven application will easily produce resistance or cause residual toxicity to current crops or subsequent crops
