Non-polluting Chinese herb insecticide

Abstract

The present invention discloses a non-polluting Chinese herb insecticide, which is made from the following raw materials by weight: 5-9 parts of stemona japonica, 6-10 parts of coptis chinensis, 10-15 parts of semiaquilegia adoxoides, 8-13 parts of viola yedoensis makino, 10-16 parts of forsythia suspensa, 5-10 parts of saposhnikovia divaricata, 5-8 parts of perilla frutescens, and 8-15 parts of cirsium setosum. According to the present invention, the modern science and technology biotechnology is used, the selected raw materials are subjected to the scientific matching, the pollution-free broad-spectrum special soil insecticide is extracted by using supercritical carbon dioxide, and compared with the water boiling method in the prior, the extraction method of the present invention has the following characteristics that various active ingredients are easily extracted, the utilization rates of the traditional Chinese medicines are high, the insect disinfestation and antibacterial effect is good, the drug nature is mild, insects, bacteria and eggs in the soil can be effectively killed while environment pollution is not generated, no toxic-side effect is generated on human and animals, the duration time is long, the insecticide consumption is low, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pollution-free Chinese herbal pesticide. Background technique [0002] my country is one of the earliest countries to use pesticides and has a very long history. The use of organochlorine pesticides in the late 1980s had a great impact on the soil. With the vigorous promotion of pollution-free agricultural products in my country , high-efficiency, low-toxicity, and low-residue pesticides are gradually being respected by consumers, and the widely used pesticides are still chemical preparations after all. Although they have good insecticidal effects, such low-residue chemicals are still harmful to the environment. It will cause pollution, have toxic and side effects on humans and animals, and is not conducive to long-term development.
