Abstract

The invention discloses a botanical pesticide and a preparation method thereof. The botanical pesticide comprises solvent extraction liquor consisting of, by weight, 60-300 parts of tobacco, 40-300 parts of camphor, 10-100 parts of Artemisia desertorum, 20-120 parts of Inula britannica, 10-100 parts of Tagetes erecta L., 10-100 parts of Anisodus tanguticus, 20-80 parts of Euphorbia Esula Linn., 50-200 parts of Artemisia annua Linn. and 40-200 parts of Plantago depressa Willd., and solvents include water, ethanol, glycerol and petroleum ether. The botanical pesticide is remarkably effective in killing multiple kinds of pests, long in pesticide effect lasting time and free of environmental pollution and provides functional substances for crop growth.

Description

technical field [0001] The invention relates to the field of pesticide processing, in particular to a botanical pesticide and a preparation method thereof. Background technique [0002] The production and use of chemical pesticides are highly toxic and have high residues, which can kill natural enemies. Long-term use can easily lead to resistance of pests, as well as pollute the environment and pose threats to human health. Global attention has been paid to resource and environmental issues to achieve sustainable development strategies It has been recognized and responded by countries all over the world. In order to improve the quality of human living environment and food, countries all over the world are doing research on reducing the amount of chemical pesticides. In the past ten years, European countries have reduced the amount of conventional pesticides to varying degrees. In 2000, the amount of pesticides used was reduced by 50% compared with the average level in the 1...
