Weeding composition containing N-(1, 3, 4-oxadiazole-2-yl)aryl formamide compound and application thereof

Abstract

The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing an N-(1, 3, 4-oxadiazole-2-yl)aryl formamide compound and application of the weeding composition. The composition comprises an active component A and an active component B in effective mounts for weeding, wherein the active component A is compounds shown in the specificationor salts thereof; and the active ingredient B is selected from one or more of the following compounds and salts/esters thereof: an HPPD inhibitor, a PDS inhibitor, a DOXP inhibitor, an ALS inhibitor, an ACCase inhibitor, a PPO inhibitor, a PSII inhibitor, a microtubule assembly inhibitor and the like. The composition can effectively prevent and remove cyperaceae weeds such as cyperus difformis, cyperus iria, scirpus juncoides and the like, grassy weeds such as rice barnyard grass, digitaria sanguinalis, barnyard grass, leptochloa chinensis and the like, and broadleaf weeds such as monochoria vaginalis, sagittaria trifolia, polygonum lilac, rhizoma alismatis and the like in crop fields, and has the characteristics of expanding the herbicide controlling spectrum, reducing the application amount, generating a synergistic effect, solving resistant weeds and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a herbicidal composition containing N-(1,3,4-oxadiazol-2-yl)aryl formamide compounds and application thereof. 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. For example, the patent CN103596946A discloses N-(1,3,4-oxadiazol-2-yl) aryl formamide and its use as a herbicide, but it still needs to be developed in production with high safety, wide ...
