Embodiment 1

[0058] Embodiment 1 adopts the active component of the herbicidal composition of the present invention as the indoor combined action of component A and component B on weeds, respectively, and component A is compound A-3, A-4, Compound A-5 is taken as an example, and component B is taken as an example of one of B1 quizalofop-p-ethyl, B2 high-efficiency fenfluthofop, and B3 clethodim.

[0059] The combined effect of the composition on weeds was clarified by indoor pot experiments.

[0060] The method for cultivating weeds is as follows: Quantitative weed seeds abalone and foxtail are respectively sown in paper cups with a diameter of 7 cm containing nutrient soil, and then cultivated in a greenhouse after sowing, covering with soil, suppressing and drenching. The grass weeds grew to the 5-7 leaf stage, and the broad-leaved weeds were at the 6-8 leaf stage. The stems and leaves were sprayed, and the experiment was repeated 3 times. The treated liquid was naturally air-dried, pla...

Embodiment 2

[0086] Example 2 The herbicides of the present invention were applied in vacant citrus groves for controlling unwanted vegetation.

[0087] The test plot is located in Meijia Village, Shuanggang Street, Kecheng District, Quzhou City, Anhui Province. The terrain is flat and the soil type is paddy soil. Weeds in the field include Xiaofei Peng, nightshade, hyssop, endive selling vegetables, gangbangui, Lushang, spicy Polygonum, crabgrass, foxtail, sage grass, iron amaranth, physalis, thatched raspberry, fluffy raspberry, snakeberry , sedge, campanula, ghost needle grass, revolutionary vegetables, well-side grass, powder rose and so on. A variety of weeds are mostly published in communities. The main weeds are Xiaofei Peng, Solanum nigrum, Achyranthes, endive selling vegetables, Gangbangui, Lushang, Spicy Polygonum, crabgrass, Setaria, Campanula, Physalis, most species of weeds are in the middle and late stages of vigorous growth .

Abstract

The invention relates to a herbicide composition and an application method thereof. The composition comprises an active component A and an active component B, wherein the component A is selected froma compound represented by a following general formula, and the component B is one selected from acetyl-CoA carboxylase (ACC) inhibitor type herbicides. The herbicide composition disclosed by the invention is particularly suitable for preventing and removing weeds with tolerance or resistance to organophosphorus herbicides, especially glyphosate.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a herbicidal composition and application thereof. Background technique [0002] Patent WO2016095768 reports isoxazoline-containing uracil compounds as shown in general formula I: [0003] [0004] The compound of general formula I has good herbicidal activity and can effectively control barnyardgrass, foxtail, sedge, water sedge, crabgrass, sedge grass, abalone, zinnia, amaranth, purslane, sagebrush Weeds at different leaf stages such as ear, nightshade, cassia, wild watermelon seedlings, wild soybeans, etc., can get a good herbicidal effect at low doses. [0005] Acetyl-Coenzyme A carboxylase (ACCase enzyme) inhibitor herbicides have excellent control effect on grass weeds. According to existing literature reports, there are mainly 4 types of such herbicides, namely aryloxyphenoxypropionic acid. Esters, oxime ethers cyclohexanediones, aryloxyphenyl cyclohexanediones and...
