Description
Technical Field
The invention relates to the technical field of pesticides, in particular to a low Wen Caogan phosphine isopropyl amine salt resistant solution agent, a preparation method and application thereof.
Background
Glyphosate is also known as: the novel agricultural chemical is characterized in that the novel agricultural chemical is composed of benomyl, agricultural chemical reaches (Roundup), glyphosate and glyphosate, is a high-efficiency, low-toxicity, broad-spectrum and systemic herbicide, and is the pesticide variety with the largest production in the world today. Glyphosate inhibits mainly enolpyruvylshikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine and tryptophan, and interfering with protein synthesis, leading to plant death. Glyphosate is absorbed by the stems and leaves and then transmitted to all parts of plants, and can prevent and kill more than 40 families of plants such as monocotyledonous and dicotyledonous plants, annual and perennial plants, herbaceous plants, shrubs and the like. After the glyphosate is buried in the soil, the glyphosate is combined with metal ions such as iron, aluminum and the like to lose activity, and the glyphosate has no adverse effect on hidden seeds in the soil and soil microorganisms. However, because glyphosate has very low solubility in water, in practical use, glyphosate is usually formulated as glyphosate salts, and glyphosate isopropylamine salt is one of the most effective varieties of glyphosate salts.
For example, the patent publication No. CN114680130A discloses a glyphosate isopropylammonium salt soluble solution and a preparation method thereof, and the glyphosate isopropylamine soluble solution comprises the following components in percentage by mass: 62-72% of glyphosate isopropylamine salt, 1-5% of compound auxiliary agent and 100% of deionized water; the preparation method of the glyphosate isopropylamine salt soluble solution has simple preparation process, less equipment investment and no three wastes, the obtained high-content solution product has transparent appearance and no crystallization precipitation after being stored at 0 ℃ for 90 days, and the use of the compound auxiliary agent generates a synergistic effect on preventing and killing weeds, and the solution has higher prevention effect on preventing and killing gramineae weeds, broadleaf weeds, such as non-cultivated weeds, citrus orchards and the like at the dosage of 180-240 g/mu; however, because of the existence of a waxy layer on the surfaces of the stems and leaves of the weeds, the herbicide has an obstructing effect on the penetration of the liquor, and the absorption rate of the weeds to the glyphosate isopropylamine salt is lower, so that the weeding efficiency of the glyphosate isopropylamine salt is affected.

5. The low Wen Caogan phosphine isopropyl amine salt resistant solution according to claim 3, wherein in the step 3), the mass ratio of the heptamethyltrisiloxane polyoxyethylene ether, the modified polyoxyethylene ether, the phosphotungstic acid and the maleic anhydride is (5-10): (3-6): (0.3-0.8): (10-18);
the concentration of the sodium hydroxide solution is 30-35 wt%.
6. The low Wen Caogan phosphine isopropyl amine salt resistant solution formulation of claim 1, wherein the stabilizer microemulsion is formulated as follows:
adding deionized water into a container, adding fatty alcohol polyoxyethylene ether, stirring and heating to 50-60 ℃, then adding octamethyl cyclotetrasiloxane, continuously stirring for 20-30 min to obtain a pre-emulsion, maintaining the temperature unchanged, adding dodecylbenzene sulfonic acid, heating to 75-85 ℃, reacting at constant temperature for 3-5 h, cooling to room temperature after the reaction is finished, and regulating the pH value to 6-7 by using triethanolamine to obtain the required stabilizer microemulsion.
7. The low Wen Caogan phosphine isopropyl amine salt resistant solution of claim 6, wherein the deionized water, fatty alcohol polyoxyethylene ether, octamethyl cyclotetrasiloxane, dodecylbenzene sulfonic acid are used in a ratio of (100-200) mL: (0.2-0.5) g: (10-20) g: (0.3-0.8 g).
8. A preparation method of a low Wen Caogan phosphine isopropyl amine salt resistant solution, which is characterized in that the low Wen Caogan phosphine isopropyl amine salt resistant solution is obtained after weighing, mixing and filtering the components according to any one of claims 1 to 7.
9. Use of a low Wen Caogan phosphine isopropyl amine salt resistant soluable agent as claimed in any one of claims 1 to 7 in the preparation of a herbicide.
10.
