Synergistic weeding composition and application thereof

Abstract

The invention belongs to the technical field of pesticide synergism, and in particular relates to a synergistic weeding composition containing 1-(2-chloro-3-(3-cyclopropyl-5-hydroxyl-1-methyl-1H-pyrazole-4-carbonyl)-6-trifluoromethylphenyl) piperidine-2-ketone or a salt and ester thereof. The synergistic weeding composition contains a weeding effective quantity of active ingredients A and B, wherein A is a compound shown in the specification or a salt thereof, C1-C4 carboxylic ether, and benzoate; and B is selected from 1) phenoxy carboxylic acids, 2) pyridine carboxylic acids, 3) benzoic acids, 4) nitriles, 5) triazolinones, 6) diphenyl ethers, 7) thiadiazoles, 8) pyrimidine diones, 9) amides, 10) sulfonylureas, 11) slalfamides, 12) pyrazoles, 13) thiocarbamates, 14) bentazone and the like. The composition can effectively prevent and remove grassy weeds and broadleaf weeds in a wheat paddock, and has the characteristics of expanding a weeding spectrum, being obvious in synergistic effect, reducing the application amount, being safe to crops, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticide synergism, in particular to a compound containing 1-(2-chloro-3-(3-cyclopropyl-5-hydroxyl-1-methyl-1H-pyrazole-4-carbonyl)-6 - A synergistic herbicidal composition of trifluoromethylphenyl)piperidin-2-one or its salts and esters 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.
