Cinnamaldehyde insecticide as well as preparation and use method thereof

Abstract

The invention provides a cinnamaldehyde insecticide as well as preparation and use method thereof. The preparation of the cinnamaldehyde insecticide comprises the following steps of collecting 100 parts of cortex cinnamomi; adding 3 to 5 parts of dry aloe leaves; performing uniform mixing and crushing; performing sieving by a sieve being 100 meshes; then, adding 5 parts of bee wax and ethyl acetate for sealed soaking for 24h; then, performing ultrasonic extraction for 30min; after the soaking is completed, performing filtering; after the filtering, putting the solid into water being 50 DEG C to be soaked for 0.5h; after fishing the solid impurity, fast cooling boiling and soaking liquid to the room temperature; extracting the boiling and soaking liquid twice by the ethyl acetate; extracting the soaking liquid once by water; taking the ethyl acetate in two times to be partially mixed; performed reduced pressure concentration at a temperature below 60 DEG C to obtain cinnamaldehyde; uniformly mixing 40 to 100 parts of cinnamaldehyde with 10 to 60 parts of natural coconut oil. The cinnamaldehyde insecticide specially aims at red spiders; the consumption of the insecticide is reduced;the environment pollution is reduced; the safety is realized on people and livestock; the environment compatibility is high; drug resistance cannot easily occur; the ingredients are simple; the preparation is convenient; wide applicability is realized in the field of red spider killing.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to botanical pesticides. Background technique [0002] At present, the grains spoiled by pests and diseases in the world account for 20-40% of the total harvest every year. In order to deal with these pests and diseases, more than 2 million tons of pesticides are produced in the world every year for prevention and control. However, the vast majority of these pesticides are chemical pesticides. The importance is obvious, but the harm it brings cannot be ignored. Many problems such as pesticide residues, environmental pollution and chronic poisoning need to be solved urgently. With the increase of human safety awareness, the development of high-efficiency, low-toxic, low-residue, and environmentally compatible pesticides that meet the concepts of environmental protection, health, and sustainable development has become the direction of pesticide development and research today.

AI Technical Summary

Problems solved by technology

[0005] Most of the existing pesticides that can prevent and control red spiders are chemical pesticides, which have large residues and cause great environmental pollution. Although there are also a small amount of botanical pesticides that can kill red spiders, the research and development of botanical pesticides put too much emphasis on broad-spectrum This results in poor pertinence and poor control effect on spider mites.
