Herbicidal composition comprising heterocycloamide compounds and applications thereof

Abstract

The invention belongs to the field of pesticides and particularly relates to an ccomposition comprising heterocycloamide compounds and applications thereof. The herbicidal composition includes, in herbicidal effective amount, an active component A and an active component B, wherein the active component A is one or more selected from the compounds as the following general formula, wherein when R1 refers to SEt and R2 refers to H, the compound is A1, when the R1 refers to CH2S-(i-Pr) and R2 refers to Me, the compound is A2, when the R1 refers to CH2SO2-(i-Pr) and R2 refers to Me, the compound isA3, when the R1 refers to CH2SO2Et and the R2 refers to Me, the compound is A4; the active component B is one or more selected from the following compounds and salt/ester thereof: organophosphorus, triazines, substituted ureas, triketones, etc. The herbicidal composition can effectively prevent and remove weeds such as Echinochloa phyllopogon, common crabgrass herb, difformed galingale herb, Italian ryegrass, dayflowers, starwort, sheathed monochoria herb and the like. The herbicidal composition is enlarged in herbicidal spectrum and reduced in application amount, has synergistic effect, andcan deal with resistance weeds.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicidal composition containing heterocyclic amide compounds and its application. Background technique [0002] Chemical herbicide is the most economical and effective means of controlling weeds in farmland, but long-term continuous high-dose use of a single species or single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective methods to solve the above problems. Patents CN105229005A, JP2016025116, and JP2017246933 respectively disclose a heterocyclic amide compound or a salt thereof and related herbicidal compositions. In production, it is still necessary...
