Weeding composition containing R-type pyridyloxycarboxylic acid derivative and synthetic hormone inhibitor and application thereof

Abstract

The invention belongs to the field of pesticides, and particularly relates to a weeding composition containing an R-type pyridyloxycarboxylic acid derivative and a synthetic hormone inhibitor and an application of the weeding composition. The composition comprises active ingredients A and B with effective weeding amounts, A is selected from one or more of R-type pyridyloxycarboxylic acid as shown in a formula I and salt and ester derivatives thereof, and R1 and R2 independently represent halogen and the like respectively; R3 represents halogen or the like; Q represents a C1-C6 alkyl group or the like; Y represents an amino group or the like; and B is selected from one or more of the following synthetic hormone inhibitor weeding compounds or acids/salts thereof: triclopyr, 2-methyl-4-chloro-phenoxyacetic acid, dicamba, picloram, aminopyralid, fluroxypyr, halauxifen-methyl, halauxifen-methyl, quinclorac and clopyralid. The composition can effectively prevent and remove various gramineous or broadleaf weeds and the like, and has the characteristics of expanding the weed control spectrum, reducing the application amount, generating a synergistic effect, solving resistant weeds and the like.

Description

Technical field [0001] The present invention belongs to the field of pesticide, and more particularly to the weeding composition comprising R-type pyridyl carboxylic acid derivatives and synthetic hormone inhibitors. Background technique [0002] Chemical weeding is the most economical and effective means of farmland weeds, but long-term continuous high doses use a single variety or a single-mode chemical herbicide, which is easy to cause problems such as weed resistance and resistance. The reasonable compound or mixing of the herbicide compound has the advantages of expanding the weapon, improving the effects, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective ways to solve the above problems. Therefore, the production still needs high security, killing grass, and can generate a synergistic effect and solve the problem of weeding combination of resistant weed problems. Inventive content [0003] To solve the above pr...
