Plant environment-friendly pesticide and its preparation method

Abstract

The invention discloses a plant environment-friendly pesticide and its preparation method, and belongs to the technical field of pesticide. The plant environment-friendly pesticide is prepared from, by weight, 10-20 parts of folium mori, 5-15 parts of thunder godvine, 10-20 parts of pyrethrum, 5-15 parts of Chinese honey locust, 10-20 parts of hairyvein agrimony, 4-10 parts of siberian cocklebur,5-15 parts of calamus, 5-15 parts of semen strychni, 10-20 parts of cordate houttuynia, 5-15 parts of Chinese honey locust, 10-20 parts of radix stemonae, and 5-15 parts of pericarpium granati. The plant environment-friendly pesticide is free from harm and side effect to people and animals; meanwhile, the plant environment-friendly pesticide has high-efficient insecticidal action, and is free fromenvironment pollution and residue, and has good economic value and social value.

Description

technical field

[0001] The invention relates to a plant environment-friendly pesticide and a preparation method thereof, belonging to the technical field of pesticides. Background technique

[0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc. They can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. In recent years, a batch of high-efficiency and low-toxic pesticides have appeared. Now people have found specific pesticides, that is, hormonal pesticides. Most of the pesticide residues used by people today are harmful to crops. The raw materials...
