Problems solved by technology

On the basis of indoor screening and field experiments, the inventors of the present application have screened out the compound composition of fenfentrazone and clodinafop-propargyl according to the weed control effect, which has the best performance on grass weeds and broad-leaved weeds in wheat fields. However, no one has reported about the herbicidal composition and application of the two, and fenfentrazone is also applied to wheat fields for weeding for the first time.

Abstract

The invention relates to a weeding composition containing topramezone and clodinafop-propargyl. The weeding composition has a synergetic effect. The weight ratio of topramezone to clodinafop-propargyl is (1 to 15)-(10 to 3), preferably is (1 to 1)-(1 to 5) and most preferably is 1 to 2.

Description

technical field [0001] The invention belongs to the field of herbicide compounding, and specifically relates to a herbicidal composition containing fenfentrazone and clodinafop-propargyl, the herbicidal composition uses fenfentrazone and clodinafop-propargyl as main active ingredients, and has a herbicidal effect Good, safe for crops, low residue and other characteristics. Background technique [0002] Weeds in wheat fields are common and there are many kinds. At present, there are gramineous weeds that are more serious in harm: barley, brome, wild oats, kangaroo, Japanese kanko, ryegrass, bluegrass, and oatgrass , hard grass, etc.; broad-leaved weeds: wormwood, shepherd's purse, pig's weed, field bindweed, Maijiagong, gray vegetables, etc. Weeds compete with wheat for water, fertilizer, space, sunlight, etc. Once it occurs, it will lead to a decrease in wheat production, and in severe outbreaks, even crop failure, which is very harmful. In recent years, due to mechanized ...
