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

Abstract

The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing N-(1, 3, 4-oxadiazole-2-yl) aryl formamide racemate and application of the weeding composition containing the N-(1, 3, 4-oxadiazole-2-yl) aryl formamide racemate. The composition comprises an active component A and an active component B with effective weeding amounts, and the active component A is a substance shown in the specification or a salt 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 and the like, grassy weeds such as rice barnyard grass, barnyard grass, Euphorbiae Semen and the like, and broadleaf weeds such as monochoria vaginalis, sagittaria trifolia, Ludwigia prostrata 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

[0001] The application date is October 30, 2019, the application number is 201911045226.2, and the title of the invention is "Herbicidal composition containing N-(1,3,4-oxadiazol-2-yl) aryl formamide compounds" and its application” is a divisional application of the Chinese invention patent application. technical field [0002] The invention belongs to the field of pesticides, in particular to a herbicidal composition containing N-(1,3,4-oxadiazol-2-yl) aryl formamide racemate and application thereof. Background technique [0003] 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 de...
