Abstract

The invention discloses plant-derived insecticide for organic vegetables. The plant-derived insecticide comprises the following raw materials: pericarpium arecae, cassava roots, metaplexis japonica makino leaves, eggplant peel, Chinese tallow leaves, cortex meliae, ailanthus altissima leaves, croton leaves, fatty acid glyceride and ascorbic acid. The invention further provides a preparation methodof the plant-derived insecticide for the organic vegetables. The preparation method comprises the steps as follows: washing, drying and pulverizing the fresh pericarpium arecae, the cassava roots, the metaplexis japonica makino leaves, the eggplant peel, the Chinese tallow leaves, the cortex meliae, the ailanthus altissima leaves and the croton leaves respectively, and mixing to prepare a mixture; extracting the mixture separately by an acetone solution and an ethanol solution, mixing the extractive uniformly, adding the fatty acid glyceride and the ascorbic acid, and performing concentrationto prepare the plant-derived insecticide for the organic vegetables. The insecticide provided by the invention is rich in a variety of alkaloids and organic substances, good in insecticidal and bactericidal effects, simple in preparation process and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a botanical pesticide for organic vegetables and a preparation method thereof. Background technique [0002] Insecticide refers to a kind of agent mainly used to control agricultural pests and urban sanitation pests, such as controlling beetles, flies, grubs, nasal worms, collembola and nearly ten thousand other pests. Insecticides mainly include natural insecticides and organic synthetic insecticides. Among them, natural insecticides and inorganic compounds have a single effect, large dosage, and short duration, while organochlorine, organophosphorus, and carbamates, etc. Synthetic insecticides have high insecticidal efficiency, but they have high residual levels and high acute toxicity. It is forbidden to use any chemically synthesized pesticides, fertilizers, growth regulators and other chemical substances in the production process of organic vegetables. Therefore, how to ...
