Embodiment 1

[0019] Mix 10kg of methylated soybean oil, castor oil and 5kg of ethylene oxide condensate as an oil phase and add to 25kg of cis-cypermethrin 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, use a homogenizer to homogenize, thicken, and defoam to obtain a milky 25% cis-cypermethrin suspension concentrate product.

Embodiment 2

[0021] Mix 30kg of corn oil and 10kg of polyoxyethylene fatty acid ester as an oil phase and add 5kg of cis-cypermethrin raw 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% cis-cypermethrin suspension concentrate product.

Embodiment 3

[0023] 15kg of soybean oil and 10kg of triethanol monooleate were mixed as the oil phase and added to 50kg of the original drug of cis-cypermethrin, 2kg of alkylphenol polyoxyethylene ether succinate half-ester sulfonate, and 0.5 kg of α-olefin sulfonate. kg, sodium lignosulfonate 2.5kg, methyl cellulose 1kg, 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% cis-cypermethrin suspension concentrate product.

Abstract

The invention discloses an alpha-cypermethrin suspension preparation containing vegetable oil and derivatives thereof, as well as a preparation method and application of the alpha-cypermethrin suspension preparation. The alpha-cypermethrin suspension preparation comprises the following components in percentage by weight: 1-50% of alpha-cypermethrin, 1-40% of vegetable oil and derivatives thereof, 0.5-10% of wetting agent, 0.5-10% of dispersant, 2-15% of emulsifier, 0.05-5% of thickener, 0.05-5% of defoaming agent, 1-10% of anti-freezing agent, 0.1-10% of preservative and the balance of water, wherein the water is supplemented till 100%. The alpha-cypermethrin suspension preparation disclosed by the invention has the advantages of evaporation resistance, strong spreading and adhesive capacity of a medicament, strong permeability and the like by improving the original composition and adding the vegetable oil and the derivatives thereof, so that the biological activity of an original preparation product is improved, the using effect of the preparation in a field is significantly improved, and the preparation is used for controlling lepidoptera and hemiptera pests against a variety of crops.

Description

technical field [0001] The invention relates to a pesticide preparation and its preparation method and application, in particular to a cis-cypermethrin suspension preparation 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 transpo...
