Abstract

The invention discloses a plant insecticide and a preparation method thereof. The plant insecticide comprises the following raw materials in parts by weight: 5-15 parts of radix aconiti kusnezoffii, 5-20 parts of achnatherum inebrians, 5-10 parts of falsehellebore root and rhizome, 10-20 parts of cacumen platycladi, 10-25 parts of peach leaf, and 10-20 parts of common threewingnut root. The preparation method comprises crushing radix aconiti kusnezoffii, achnatherum inebrians, falsehellebore root and rhizome, cacumen platycladi, peach leaf and common threewingnut root, adding water with the amount being 20 times of the weight of the raw materials, boiling, then continuing boiling for 2-4 h, filtering to obtain the medicinal soup which is the product. The insecticide is capable of effectively controlling aphis gossypii, red spider, cabbage caterpillar and other farmland insects, and is green and nontoxic.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a plant pesticide and a preparation method thereof. Background technique [0002] At present, the pests and diseases of crops are controlled by chemical pesticides, and the use of chemical pesticides can easily cause pests to develop resistance and reduce the insecticidal effect of pesticides. At the same time, chemical pesticides remain in crops and enter the human body through the food chain, posing a threat to human health. In order to solve the above-mentioned disadvantages, the present invention selects several plants capable of preventing and killing diseases and insect pests as raw materials, and develops a pollution-free plant insecticide and a preparation method thereof. Contents of the invention [0003] The invention proposes a plant insecticide and a preparation method thereof, which not only can kill insects efficiently, but also contain all plants, are gree...
