Abstract
The invention discloses a compound herbicide composition containing pyraflufen-ethyl, which comprises the components of pyraflufen-ethyl, diflufenican and a plant source component, wherein the plant source component is a black tartary buckwheat-ageratum extract, and the preparation method of the plant source component comprises the following steps: cleaning the whole plant of ageratum conyzoides, cutting into small pieces, grinding the black tartary buckwheat into powder, mixing the powder and the small pieces to obtain a raw material mixture, adding deionized water into the raw material mixture, extracting for 4-5 hours in a water bath at 65 +/-5 ℃, cooling to normal temperature after extraction, performing solid-liquid separation, and performing liquid phase reduced pressure concentration to obtain the plant source component. The composite herbicide disclosed by the invention has a good weed control effect, is simple in preparation process, and solves the problem of poor weeding effect of a single herbicide. The compounded herbicide components act on weeds in different modes, so that the weeding effect is improved, the drug resistance of the weeds is reduced, and the herbicide composition is particularly suitable for removing annual gramineous weeds in fields.
Description
Technical Field
The invention relates to the technical field of herbicides, and in particular relates to a compound herbicide composition containing pyraflufen-ethyl and a preparation method thereof.
Background
The pyroxasulfone is a novel isoxazole selective herbicide taking ultra-long chain fatty acid as a target, after the selective isoxazole selective herbicide is absorbed by young roots and young buds of weeds, meristems and coleoptiles of the seedlings are damaged, so that the growth of the weeds is inhibited, the control spectrum is similar to that of chloroacetamide herbicides such as acetochlor and metolachlor, gramineous and broad-leaved weeds can be effectively controlled, and the herbicide has the advantages of low dosage, high activity, long duration and the like. Diflufenican (Picolinafen) is a picolinamide structural compound that was the earliest herbicide developed by BASF corporation. The medicine has good inhibiting and preventing effects on various annual grassy weeds and broadleaf weeds including Larrea sinensis, viola wildica, aleurites communis and other grassy weeds and barnyard grass and other grassy weeds. The action mechanism after the application is as follows: diflufenican can inhibit the synthesis of carotenoid, and can cause the chlorophyll of cells of weed plants to be damaged and the cells to be broken through inhibiting the activity of phytoene desaturase in the weed plants, thereby finally leading the weed plants to die. The diflufenican has the advantages of high weeding performance, long action time, small toxic and side effects on crops, multiple applicable crop varieties and the like, so that the diflufenican always keeps better sales since the diflufenican comes into the market, and has wider market application and development prospects. Plant-derived herbicides are one of the current herbicide development directions, and it has been found that more than 30 plants in the world contain nearly hundreds of natural compounds with herbicidal activity, some of which have been developed into natural herbicides and patented and popularized.
The combined use of two or more herbicides to synergize the overall herbicide effect is a common technical means in the field, for example, CN113100244A discloses a herbicide composition with a broad weed control spectrum and a significant weed control effect and the application thereof. The quinclorac and the terbutryn with different structure types and action mechanisms are compounded for use, so that drug property counteraction or other side effects cannot occur, but an obvious synergistic effect is achieved, and the control effects of the two components on annual and perennial gramineous weeds and broadleaf weeds can be improved to a greater extent; also, for example, CN112806377A discloses a herbicide composition containing clopyralid and saflufenacil and an application thereof, active ingredients of the herbicide composition are clopyralid and saflufenacil, a mass ratio of the clopyralid to the saflufenacil is 1. The composition of the invention has obvious synergistic effect on controlling alternanthera philoxeroides in the range of the mixture ratio. Therefore, the technical scheme of using two or more herbicides in combination to improve the herbicide potency has become one of the important research and development directions in the field.
Disclosure of Invention
Therefore, the invention provides a compound herbicide composition containing the sulfure pyraflufen, which comprises the components of the sulfure pyraflufen, diflufenican and a plant source component, wherein the plant source component is a black tartary buckwheat-ageratum japonicum extract, and the preparation method of the plant source component comprises the following steps: cleaning the whole plant of ageratum conyzoides, cutting into small pieces, grinding the black tartary buckwheat into powder, mixing the powder and the small pieces to obtain a raw material mixture, adding deionized water into the raw material mixture, extracting for 4-5 hours in a water bath at 65 +/-5 ℃, cooling to normal temperature after extraction, performing solid-liquid separation, and performing liquid phase reduced pressure concentration to obtain the plant source component.
Further, the composite herbicide composition also comprises a synergist, a dispersant and a stabilizer, the synergist is a mixture of alpha-terpineol, coumarin and myristic acid, and the preparation method of the synergist comprises the following steps: and (2) mixing the alpha-terpineol, the coumarin and the myristic acid according to the mass ratio of alpha-terpineol: coumarin: the ratio of myristic acid =1 is 0.5-0.8, and the following components are uniformly mixed in a ratio of 1-2, the mixture is placed in a water bath kettle with the temperature of 60 +/-5 ℃, stirred for more than 10min and then cooled to the normal temperature in air, and the synergist is obtained.
Further, the dispersing agent is sodium lignosulfonate, and the stabilizing agent is tricalcium phosphate.
Further, the ratio of the adding mass of the synergist, the dispersant and the stabilizer to the total mass of the composite herbicide composition is that the synergist is as follows: dispersing agent: a stabilizer: the composite herbicide composition = 4-6.
Furthermore, the components comprise 6-16 parts of the sulfuryl pyraflufen, 1-10 parts of the diflufenican and 3-4 parts of the plant source component according to the parts by weight.
Further, the mixing mass ratio of the black tartary buckwheat powder to the ageratum conyzoides dices is that the black tartary buckwheat powder/the ageratum conyzoides dices = 1-10.
