Embodiment 1

[0058] Embodiment 1 adopts the active component of the herbicidal composition of the present invention to be that component A is combined with component B to measure the indoor combined action on weeds respectively, and component A uses A-3, A-4, 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 haloxyfop-pyl, and B3 clethodim.

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

[0060] The weed cultivation method is as follows: sow quantitative weed seeds Abutilon and Setaria respectively in paper cups with a diameter of 7 cm filled with nutrient soil, and then cultivate them in a greenhouse after covering with soil, pressing, and watering. Gramineae weeds grow to the 5-7 leaf stage, broad-leaved weeds 6-8 leaf stage, the stems and leaves are sprayed, and the experiment is repeated 3 times. After treatment, the medicinal solution was naturally...

Embodiment 2

[0086] Example 2 Idle application of the herbicides according to the invention in citrus orchards for the control of undesired vegetation.

[0087] The test plot is in Meijia Village, Shuanggang Street, Kecheng District, Quzhou City, Anhui Province. The terrain is flat and the soil type is rice field soil. Weeds in the field include small flying florets, solanum nigrum, achyranthes bidentata, lettuce, barbangui, land business, spicy Polygonum, crabgrass, foxtail, weed grass, iron amaranth, physalis grass, sorrel, fluffy, snakeberry , sedge, campanula, ghost needle grass, revolutionary vegetable, well edge grass, powder group rose, etc. Various weeds are mostly released in groups. The main weeds are Xiaofei Peng, Solanum nigrum, Achyranthes bidentata, Chimai vegetable, Banbangui, Lushang, Polygonum, crabgrass, Setaria, Campanula, Physalis, and most of the weeds are in the middle and late stages of vigorous growth .

Abstract

The present invention relates to a herbicide composition and its application method. The composition consists of two active ingredients A and B, wherein component A is selected from compounds represented by the following general formula: component B is selected from acetyl-CoA carboxylase (ACCase enzyme) inhibitor herbicide. The herbicide composition of the present invention is particularly suitable for controlling weeds that are tolerant or resistant to organophosphorus herbicides, especially glyphosate.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a herbicide composition and its application. 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, heteromorphous sedge, water sedge, crabgrass, weed grass, velvetleaf, zinnia, retroflexus, purslane, Weeds of different leaf stages such as ears, black nightshade, cassia, wild watermelon seedlings, and wild soybeans can achieve good weeding effects at low doses. [0005] Acetyl-CoA carboxylase (ACCase enzyme) inhibitor herbicides have excellent control effects on grass weeds. According to existing literature reports, there are mainly 4 types of such herbicides, namely aryloxyphenoxypropionic acid Esters, oxime ether cyclohexanediones, aryloxyphenyl cyclohexanediones a...
