preparation example Construction

[0016] The present invention has made sprayable preparation according to above-mentioned prescription, and its preparation method comprises the following steps:

[0017] 1) Finely chop the fresh products of buttercup, Tianmingjing, tiger bone incense, calamus and garlic in the above formula, and then use the wine making method commonly used in the countryside to add 400-500g of distiller's yeast for every 50Kg of fresh products, and heat them at a temperature of 35 Ferment at -45°C and keep for 1-2 days to produce 8-12Kg toxic alcohol;

[0018] 2) Mix and soak 4-8Kg of the poisonous alcohol prepared above with 1-2Kg of oleander leaves shredded after drying at room temperature for 18-25 days, filter out the soaking liquid, and then mix with shredded oleander leaves after drying Another 1-2Kg of oleander leaves are mixed and soaked at room temperature for 18-25 days, and the soaking solution is filtered out;

[0019] 3) Grind 1-2Kg of fresh wild pepper and extract 0.4-0.6Kg of ...

Embodiment

[0020] Embodiment: Mince 10Kg fresh products of buttercup, Tianmingjing, tiger bone incense, calamus and garlic, then add 450g of distiller's yeast for every 50Kg of fresh products, ferment at a temperature of about 40°C, and keep it for 1 day. into 10Kg of poisonous alcohol, then take 5Kg of the above-mentioned poisonous alcohol and mix with 1.5Kg of chopped dry oleander leaves and soak for 20 days, then mix and soak the soaking liquid taken out with another 1.5Kg of chopped dry oleander leaves for 20 days, Filter out the soaking liquid; then crush 1.5Kg of fresh wild pepper and extract 0.5Kg of the juice, mix it with 3Kg of the second soaking liquid, then add 0.5Kg of alum, fully dissolve it for 2 days, then add an appropriate amount of emulsifier and serve .

[0021] Through experimentation, the use of 0.5-1Kg of the present invention per mu of crops can effectively kill pests.
