Embodiment 1

[0021] Mix 10kg of methylated soybean oil, castor oil and 5kg of ethylene oxide condensate as an oil phase and add to 25kg of pymetrozine original drug, 2.5kg of fatty alcohol sulfate, 0.5kg of α-olefin sulfonate, fatty alcohol Ether sulfate 2kg, magnesium aluminum silicate 0.5kg, organosilicon defoamer 0.05kg, ethylene glycol 5kg, sodium benzoate 0.5kg, the balance is water, and use a sand mill to carry out circulating wet pulverization to a system of 1-5 μm In the process, homogenize, thicken and defoam with a homogenizer to obtain milky white 25% pymetrozine suspension concentrate product.

Embodiment 2

[0023] Mix 30kg of corn oil and 10kg of polyoxyethylene fatty acid ester as an oil phase and add to 5kg of pymetrozine original drug, 2.5kg of fatty alcohol sulfate, 2kg of fatty amide N-methyl taurate, and nonylphenol ether sulfate 5kg of ester, 3kg of gum arabic, 2kg of silicone defoamer, 5kg of propylene glycol, 1kg of formaldehyde, and water as the balance, use a sand mill to carry out circular wet crushing into a system of 1-5μm, and then use a homogenizer for homogenization , thickening and defoaming to obtain milky white 5% pymetrozine suspension concentrate product.

Embodiment 3

[0025] 15kg of soybean oil and 10kg of triethanol monooleate were mixed as the oil phase and added to 50kg of pymetrozine original drug, 2kg of alkylphenol polyoxyethylene ether succinate half ester sulfonate, and 0.5 kg of α-olefin sulfonate kg, sodium lignosulfonate 2.5kg, methyl cellulose 3kg, silicone defoamer 1kg, glycerol 5kg, benzoic acid 0.5kg, the balance is water, and use a sand mill to carry out circular wet crushing to 1~ In a 5 μm system, use a homogenizer to homogenize, thicken, and defoam to obtain a milky white 50% pymetrozine suspension concentrate product.

Abstract

The invention discloses a preparation method and application of a pymetrozine suspension preparation containing vegetable oil and derivatives thereof. The preparation comprises the following components by weight percent: 1-50% of pymetrozine, 1-40% of vegetable oil and derivatives thereof, 0.5-10% of wetting agent, 0.5-10% of dispersing agent, 2-15% of emulsifying agent, 0.05-5% of thickening agent, 0.05-5% of defoaming agent, 1-10% of antifreezing agent, 0.1-10% of preservative and the balance of water, wherein the total weight percent is 100%. The preparation method and application have the following beneficial effects: the original components are improved and the vegetable oil and derivatives thereof are added, and the preparation has the advantages of evaporation resistance, strong pesticide spreading and adhesion capabilities, strong permeability and the like, thus improving the bioactivity of the original preparation products and obviously improving the use effect of the preparation in the field; and the preparation can be used for preventing and controlling pests with piercing-sucking mouthparts on various crops.

Description

technical field [0001] The invention relates to a pesticide preparation and its preparation method and application, in particular to a pymetrozine suspension containing vegetable oil and derivatives thereof, its preparation method and application. Background technique [0002] Pesticide suspensions mostly use water as the dispersion medium, and the insoluble or slightly soluble solid raw materials are ground and pulverized, and dispersed evenly with the help of surfactants and other additives to form a highly suspended and flowable substance with fine particles. Relatively stable liquid-solid phase system. Compared with EC, it has the advantage of avoiding the use of a large amount of organic solvents; compared with wettable powder, there is no dust flying and drifting during processing and use, and its toxicity and irritation to humans and animals are relatively low, which can reduce the phytotoxicity of crops , and will not burn during storage and transportation, with hig...
