Problems solved by technology

[0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. Annual and multi-year weeds are mixed, herbs, vines and shrubs are mixed, and the emergence of weeds is uneven, and seeds, young and old weeds are staggered, so when the herbicide species are used alone, they will show some defects and limitations

Abstract

The invention discloses a novel weeding composition and application thereof. The novel weeding composition is prepared from a first effective ingredient, a second effective ingredient and a third effective ingredient, the first effective ingredient is a composition of pendimethalin, sulfentrazone and bentazone, the second effective ingredient is a composition of clethodim and halosulfuron-methyl, the third effective ingredient is a composition of a polar organic solvent, a defoaming agent, an anticorrosive agent, kaolin and deionized water, the weight ratio of the first effective ingredient to the second effective ingredient is 1:1-60:1, and the weight percentage of the sum of the first effective ingredient and the second effective ingredient in the composition is 15%-75%. The novel weeding composition is good in preventing and treating effect and weeding effect, free of pollution to the environment, capable of delaying the weed resistance, long in lasting period, capable of not harming crops and good in safe effect.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a novel herbicidal composition and its application. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. Annual and multi-year weeds are mixed, herbs, vines and shrubs are mixed, and the emergence of weeds is uneven, and seeds, young and old weeds are staggered, so when the herbicide species are used alone, they will show some defects and limitations. Contents of the invention [0003] The object of the present invention is to provide a novel herbicidal composition and its application to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical scheme: a novel herbicidal composi...
