Embodiment 1

[0019] Mix 10kg of methylated soybean oil, castor oil and 5kg of ethylene oxide condensate as the oil phase and add to 25kg of imidacloprid original drug, 2.5kg of fatty alcohol sulfate, 0.5kg of α-olefin sulfonate, fatty alcohol ether sulfuric acid 2kg of ester, 0.5kg of magnesium aluminum silicate, 0.05kg of organosilicon defoamer, 5kg of ethylene glycol, 0.5kg of sodium benzoate, and water as the balance, use a sand mill to carry out circular wet grinding into a system of 1-5 μm, Homogenize, thicken and defoam with a homogenizer to obtain milky white 25% imidacloprid suspension concentrate product.

Embodiment 2

[0021] Mix 30kg of corn oil and 10kg of polyoxyethylene fatty acid ester as an oil phase and add to 5kg of imidacloprid original drug, 2.5kg of fatty alcohol sulfate, 2kg of fatty amide N-methyl taurate, and 5kg of nonylphenol ether sulfate , 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 to homogenize and increase After thickening and defoaming, milky white 5% imidacloprid suspension concentrate product can be obtained.

Embodiment 3

[0023] 15kg of soybean oil and 10kg of triethanol monooleate are mixed as an oil phase and added to 50kg of imidacloprid former drug, 2kg of alkylphenol polyoxyethylene ether succinate half ester sulfonate, 0.5kg of α-olefin sulfonate, Sodium lignosulfonate 2.5kg, methyl cellulose 1kg, silicone defoamer 1kg, glycerin 5kg, benzoic acid 0.5kg, the balance is water, and use a sand mill to carry out circular wet crushing to 1-5 μm In the system, a homogenizer is used for homogenization, thickening and defoaming to obtain a milky white 50% imidacloprid suspension concentrate product.

Abstract

The invention discloses an imidacloprid suspension preparation comprising vegetable oil and derivatives of the vegetable oil and a preparation method and application thereof. The imidacloprid suspension preparation comprises the following ingredients in percentage by weight: 1 to 50 percent of imidacloprid, 1 to 40 percent of vegetable oil and derivatives thereof, 0.5 to 10 percent of wetting agent, 0.5 to 10 percent of dispersing agent, 2 to 15 percent of emulsifier, 0.05 to 5 percent of thickener, 0.05 to 5 percent of antifoaming agent, 1 to 10 percent of antifreezing agent, 0.1 to 10 percent of preservative and the balance of water. The imidacloprid suspension preparation disclosed by the invention is obtained by improving the original composition and adding the vegetable oil and the derivatives thereof and has the advantages of evaporation resistance, strong spreading and adhesive ability of a reagent and strong permeability, so the biological activity of the original preparation product is improved and the field using effect of the preparation is improved. The preparation is used for preventing and treating insect 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 an imidacloprid 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 transporta...
