Mixed herbicide containing Clodinafop-propargyl and chlortoluron

Abstract

The invention discloses a mixed herbicide containing Clodinafop-propargyl and chlortoluron, which comprises the following effective ingredients of Clodinafop-propargyl, chlortoluron and Carfentrazoneethyl at the mass ratio of (4-10): (2-60): (1-10). Compared with the prior art, the mixed herbicide disclosed by the invention has the following outstanding advantages that three herbicides of Clodinafop-propargyl, chlortoluron and Carfentrazoneethyl with the complementary herbicide spectrums are chosen by the mixed herbicide containing Clodinafop-propargyl and chlortoluron to be prepared into a mixture after proper decrement. The mixed herbicide containing Clodinafop-propargyl and chlortoluron has the characteristics of high herbicide activity, wide herbicide spectrum, long residual activity, high safety and the like, delays weed resistance, can be used for preparing the herbicide for killing weeds after seedlings emerge in a wheat field, and is especially used for preventing and killing various Poaceae and broadleaf weeds in the wheat field. The mixed herbicide can be used for preventing and killing various Poaceae and broadleaf weeds in the wheat field, is safe to wheat and aftercrop on the premise of improving the pesticide effect.

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 chlorotoluron. 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, s...

AI Technical Summary

Problems solved by technology

[0013] 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
