Abstract

The invention discloses a low-toxicity plant type insecticide and a preparation method thereof and relates to the technical field of chemical engineering. The low-toxicity plant type insecticide is prepared from the following components in parts by weight: 8-15 parts of radix celastri orbiculati, 5-10 parts of cortex cinnamomi, 3-8 parts of pyrethrum, 2-5 parts of radix tripterygii wilfordii, 3-9parts of randia canthioides, 5-12 parts of green-leaf Cinnamomum camphora leaf and 1-5 parts of radix derris trifoliatae. By optimizing a proportion of various components, the prepared low-toxicity plant type insecticide has the advantages of convenience in preparation, simpleness in production, low cost, high safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a low-toxic plant-type insecticide and a preparation method thereof. Background technique [0002] Plant essential oils are secondary substances in plants, composed of simple compounds with relatively small molecular weights, can be distilled with water vapor, and have a general term for volatile oily liquid substances with a certain odor. Ancient people bathed with orchid soup, burned wormwood to lavender clothes, folks used mugwort and calamus to bathe their bodies during the Dragon Boat Festival, and used spice plants as materials for ancient buildings, all because of their disinfection, sterilization, antiseptic and insect-proof effects. The repelling effect of plant tissue on pests is essentially to use the essential oils discharged in the environment to work. Klocke found that 1,8-cineole has no toxic effect on Aedes aegypti larvae, but it is an effective adult o...
