[0035] B, the preparation of Pistacia chinensis killing cinnabar spider mite agent

[0036] The concentrate obtained in step A (ie the extract of Pistacia chinensis) and auxiliary agents are formulated into emulsifiable concentrates and microemulsions for preventing and controlling harmful organisms. The weight percent of each raw material in above-mentioned various dosage forms is:

[0037] EC: Pistacia chinensis extract 10%-50%, surfactant 5%-20%, solvent added to 100%;

[0038] Mix the extract of Pistacia chinensis, solvent and surfactant in proportion, stir evenly in the reaction kettle, the temperature of the reaction kettle is 35°C-60°C, and the stirring time is 30 minutes, and after the quality inspection, the mite-killing cream of Pistacia chinensis is obtained;

[0039] Above-mentioned solvent is one or more mixtures in methanol, ethanol, acetone, n-propanol, ethyl acetate or solvents known in the art;

[0040] The above surfactants are selected from octylphenol pol...

Embodiment 1

[0046] Embodiment 1: Preparation of 20% Pistacia chinensis EC:

[0047] Weigh 20kg of Pistacia chinensis concentrate, dissolve it in 30kg of acetone, then add 15kg of calcium dodecylbenzenesulfonate, 5kg of nonylphenol polyoxyethylene ether, acetone to make up, and mix thoroughly to obtain acaricide emulsifiable concentrate. After quality inspection, the stability and appearance of the preparation meet the requirements of commercial preparations.

Embodiment 2

[0048] Embodiment 2: the preparation of 10% pistachio microemulsion:

[0049] Weigh 10kg of Pistacia chinensis concentrate, dissolve it in 20kg of acetone, then add 15kg of calcium dodecylbenzenesulfonate and 5kg of nonylphenol polyoxyethylene ether, mix under high-speed stirring, and heat to about 30°C; under high-speed stirring Add 50 kg of deionized water dropwise, control the drop rate of water, and keep the temperature at about 30° C.; after adding the water dropwise, heat up to 40° C. and stir for 1 hour to obtain 20% Pistacia chinensis microemulsion. After quality inspection, the stability and appearance of the preparation meet the requirements of commercial preparations.

[0050] 2. Example of indoor biometrics

[0051] In this experiment, the poisonous activity of pistacia acetone extract on wood sorrel such as spider mite and spider mite was determined. The test method and test results are as follows:

[0052] 1. Test pest mites

[0053]Sorrel such as Tetranychina...
