Abstract

The invention belongs to the technical field of pesticides and particularly relates to a botanical pesticide and a preparation method thereof. The botanical pesticide is prepared from, by weight part, 10-15 parts of matrine extract, 5-8 parts of derris trifoliata extract, 8-15 parts of rue extract, 3-5 parts of pyrethrum Dalmatian extract and 3-5 parts of azadirachtin. The botanical pesticide is unique composition, reasonable in compatibility, free from residue and pollution, rapid and stable in effect, long in effect time, capable of avoiding pesticide resistance, long in duration and particularly applicable to comprehensive prevention of plecoptera pests.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a botanical pesticide and a preparation method thereof. Background technique [0002] While traditional chemical pesticides play a positive role in increasing agricultural production and preventing pests and diseases, they also bring serious side effects, such as: easily causing environmental pollution, destroying the ecological balance of nature, seriously endangering human health, and generally developing drug resistance in pests and diseases , prevention and control are becoming more and more difficult. Therefore, chemical pesticides are not suitable for people to abuse for a long time. Botanical insecticides are a class of insecticides processed from plants or plant extracts. Due to their low toxicity, easy degradation, good environmental compatibility, and the advantages of not easily producing resistance to natural enemies and pests, This makes the research...
