Embodiment 1
[0023] Embodiment 1: the preparation method of water-based low capacity agent
[0024] Dissolve the solid pesticide raw material with a small amount of solvent or melt it at high temperature, add surfactant and antifreeze agent, if it is a liquid raw drug, you can directly add surfactant and antifreeze agent, and use a high-speed shear emulsifier to fully mix the original drug to form an oil Phase; while mixing the oil phase, add the anti-volatile agent and surfactant into the water, heat it properly and disperse it in the water evenly through high-speed shearing to form a water phase; finally pour the oil phase into the water phase slowly , the water-based low-capacity agent can be obtained through high-speed shear emulsification.
Embodiment 2
[0025] Example 2: The effect of anti-volatile agent on the evaporation rate of water-based low-capacity agent
[0026] Prepare 12% beta-cypermethrin · emamectin benzoate hydration low-capacity agent according to the method of Example 1, wherein the consumption of anti-volatile agent is as follows, and the prepared product is measured for its volatilization rate, and the results are as follows.

[0028]
Embodiment 3
[0029] Embodiment 3: 12% beta-cypermethrin · emamectin emamectin salt hydration low volume agent
[0030] Formula: Beta-cypermethrin 10.5%, emamectin benzoate 0.75%, xylene 10%, isophorone 3%; sodium dodecylbenzenesulfonate 3%, castor oil polyoxyethylene ether 3% %, fatty alcohol polyoxyethylene ether 0.08%, glycerol 2%, cetyl alcohol 1%, and deionized water to make up to 100%.
