Abstract

The invention relates to a high-efficiency nontoxic insecticide and a preparation method thereof. The high-efficiency nontoxic insecticide is prepared from the following components in parts by weight: 100 parts of water, 2-30 parts of euphorbia extract, 5-50 parts of pepper extract and 15-40 parts of tobacco stem extract, wherein the euphorbia extract is extracted from daphne euphorbia plants, the pepper extract is extracted from pepper fruits, and the tobacco stem extract is extracted from tobacco leaves. The insecticide is nontoxic and harmless to human beings and livestock without polluting environment and crops or leaving toxicity. The invention has the action of preventing plant diseases and insect pests of crops, fruit trees and vegetables and preventing and curing various plant diseases and insect pests of aphids, cabbage caterpillars, and the like and has low cost, good prevention effect, long insecticide potency durability, less insecticide times and labor saving, thereby stimulating the healthy growth and the prematurity of crops, improving the product quality of crops and increasing the yield.

Description

technical field [0001] The invention relates to a pesticide insecticide and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and the poisonous pesticides such as organophosphorus and dimethoate used in agricultural production not only seriously endanger the health of farmers, but even cause the death of farmers. Moreover, the fruits, vegetables, grains and oils produced will also have residual poison, and people will be prone to cancer if they use it for a long time. Relevant state departments have proposed to prohibit the use of highly toxic pesticides and vigorously develop green and pollution-free food. Therefore, the development of botanical insecticides is a development trend of pesticides and insecticides. [0003] According to research, many natural plants contain substances that can kill insects. Plant-derived insecticides with natural phytochemicals as active ingredients have the advantages of being environme...
