Problems solved by technology

But the resulting problem is: when using a solid substance as a carrier, along with the dissolution of the water-soluble carrier, if the active ingredient is also water-soluble, it will diffuse due to the concentration difference, resulting in all the active ingredients being dissolved in the water body. To ensure the control effect, the water body must reach a certain effective concentration, which will not only waste but also cause great harm to aquatic organisms, humans, animals, etc.
[0007] If the active ingredient is insoluble in water, it is difficult to ensure that the active ingredient carried on the solid carrier can be evenly distributed in water; and the granules are easily powdered due to friction and extrusion during transportation and storage, which affects the efficacy of the drug to play
If a general organic solvent is used as the solvent system, it will also pollute the environment due to the toxicity of the solvent; at the same time, with the volatilization of the solvent, the active components in the preparation will crystallize and aggregate into solid particles because of their insoluble water solubility, which is difficult to maintain. Effective Concentration Uniformity in Water

Embodiment 1

[0024] Embodiment 1, film spreading oil:

[0025] Diffusion aid: 1 part of N,N-dimethyldecanamide;

[0026] 4 parts propylene glycol

[0027] Diffuser: Environmentally friendly surfactant (C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate: silicone polyoxyethylene ether = 1:3) 1 part;

[0028] Solvent carrier: green solvent (sesquiterpene vegetable oil: methyl esterified vegetable oil = 1:5) 50 parts;

[0029] Methyl laurate 43.5 parts.

[0030] The film-spreading oil agent obtained in this example is mixed with pymetrozine in a mass ratio of 99.5:0.5 to prepare the pymetrozine film-spreading oil agent in the corresponding proportion.

Embodiment 2

[0031] Embodiment 2, film spreading oil:

[0032] Diffusion aid: 1 part of N,N-dimethyldecanamide;

[0033] 1 part of N-methylpyrrolidone;

[0034] 16 parts of propylene glycol;

[0035] Diffuser: Environmentally friendly surfactant (C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate: silicone polyoxyethylene ether = 2:2) 15 parts;

[0036] Solvent carrier: green solvent (sesquiterpene vegetable oil: methyl esterified vegetable oil = 2:4) 30 parts;

[0037] 32 servings of soybean oil

[0038] The film-spreading oil agent obtained in this example and pymetrozine in a mass ratio of 95:5 were mixed to prepare the pymetrozine film-spreading oil agent of the corresponding proportion.

Embodiment 3

[0039] Embodiment 3, film spreading oil:

[0040] Diffusion aid: 10 parts of N-methylpyrrolidone;

[0041] 20 parts of propylene glycol;

[0042] 5 parts of polyacrylamide;

[0043] Diffuser: Environmentally friendly surfactant (C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate: silicone polyoxyethylene ether = 3:1) 12 parts;

[0044] 3 parts of dodecyl sulfate;

[0045] Solvent carrier: green solvent (sesquiterpene vegetable oil: methyl esterified vegetable oil = 3:3) 20 parts;

[0046] 20 servings of corn oil.

[0047] The pymetrozine film-stretching oil in the corresponding proportion is prepared by mixing the film-stretching oil obtained in this example with pymetrozine in a mass ratio of 90:10.

Abstract

The invention relates to pymetrozine spreading oil as well as corresponding spreading oil and diffusant thereof. The invention provides spreading oil used for assisting application of systemic technical for changing an existing application mode of technical for plants in water and also provides pymetrozine spreading oil and high-efficiency diffusant thereof. The high-efficiency diffusant has lower surface stress and can be used for rapidly diffusing effective components of systemic technical on the water surface and the technical film cannot be broken for a long time. The spreading oil for the systemic technical is mainly prepared from the following components in parts by weight: 1-93.5 parts of solvent carrier, 1-20 parts of diffusant and 1-50 parts of diffusion aid; the diffusant is mainly prepared by mixing C12 alkyl alcohol ethoxylate propoxylate phosphate and organosilicone polyoxyethylene ether according to a mass ratio of 1: 3-3: 1.

Description

technical field [0001] The invention relates to a pymetrozine film spreading oil agent and its corresponding film spreading oil agent and diffusing agent. Background technique [0002] Pymetrozine (Pymetrozine) chemical name: 4,5-dihydro-6-methyl-4-(3-pyridylmethyleneamino)-1,2,4-3(2H)-one, belonging to pyridine or Triazinone insecticide is a brand-new non-biocidal insecticide developed by Ciba-Geigy Company in Switzerland in 1988. The product has excellent control effect on piercing-sucking mouthpart pests of various crops. Pymetrozine has a contact killing effect on pests and also has systemic activity. In plants, it can be transported both in the xylem and in the phloem; therefore, it can be used both as a foliar spray and as a soil treatment. Due to its good conduction properties, the newly grown branches and leaves can also be effectively protected after the stem and leaves are sprayed. [0003] The application forms of pymetrozine in the pesticide market are mainly ...
