Wheat field weeding composite and application thereof

Abstract

The invention belongs to the field of farm chemicals and particularly relates to a wheat field weeding composite containing pyrazole ketones compounds and application thereof. The weeding composite comprises a weeding effective dose of an active ingredient A and a weeding effective dose of an active ingredient B, wherein the active ingredient A is one as shown in the following general formula (the general formula can be found in specification), R1 is hydrogen atoms, R2 is methyl, R3 is ethyoxyl, R4 is helium atoms and R5, R6 and R7 are alkyl groups; the active ingredient B is selected from one or more of the compounds including phenoxyalkanoic acids, ureas, triazole moiety ketone classes, diphenyl ethers, acetamides, aryloxy phenoxy propionic acid esters, ring adipic ketone classes, sulfonylureas, sulfonamides and phenyl pyrazole Lin classes. The composite can effectively prevent and eliminate diccot weeds in wheat fields and has the advantages that the weed spectrum is expanded, the synergistic effect is obvious, the dosage is reduced, the composite is safe to crops, and herbicide resistant weeds can be eliminated.

Description

technical field

[0001] The invention belongs to the field of pesticides, in particular to a wheat field herbicide composition containing pyrazolone compounds and its application. Background technique

[0002] The use of herbicides to control weeds is the most economical and effective means of weed control in farmland. However, long-term continuous high-dose use of a single species or a 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.

[0003] Hydroxyphenylpyruvate dioxygenase (HPPD) was discovered after inhibitors of acetyl-CoA carboxylase (ACCase), acetolactate synthase (ALS) and protoporphyrinogen oxidase (Protox)...
