Abstract

The invention discloses a pesticide suspension and a processing technique. In the step (1), a pesticide contains an effective component which is a mixed solution of acephate, quintiofos and triazolone of which the volume ratio is 1 to 1.5 to 1, the three components are widely used, and the insecticidal effect is good; a stirring dispersion method of the step (1) is ultrasonic dispersion, the ultrasonic intensity is set to 3.0, the dispersion time is 30 min, by utilizing the method, the dispersion speed is high, and the effect is good; a preparation method of the active component of the pesticide comprises the steps of weighing the three effective components according to the volume ratio, then mixing, and stirring in vacuum low-temperature conditions, wherein the temperature is set to 5 DEG C, the volatilization of the pesticide can be reduced by stirring in the vacuum low-temperature conditions, an organic solvent of the step (1) is absolute ethyl alcohol, and the organic solvent has the advantages of wide source and good solubility.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a pesticide suspension and a processing technique thereof. Background technique [0002] Suspending agent is a viscous and flowable suspension formed by mixing the original pesticide, carrier and dispersant, and ultrafinely pulverizing it by wet method. The insoluble or slightly water-soluble solid original drug is dispersed in water relatively uniformly through ultrafine pulverization with the help of some additives, forming a stable liquid-solid system with fine particles, high suspension, and flowability. Suspending agents are usually composed of active ingredients, dispersants, thickeners, anti-sedimentation agents, defoamers, antifreeze agents and water. The content of active ingredients is generally 5% to 50%. The average particle size is generally about 3 microns. It is a new dosage form for pesticide processing. With the rapid development of agriculture, the demand for pest...
