Abstract

The invention discloses an insecticide compounded from capsaicin and a eupatorium adenophorum extract. The insecticide comprises the following raw materials by mass percentage: 0.1%-30% of capsaicin,1%-40% of the eupatorium adenophorum extract, and the balance pesticide assistants. The invention has the beneficial effects that: the provided botanical insecticide has simple preparation method andwide raw material sources, is low in production cost, has the characteristics of zero pesticide residue, high control effect, wide insecticidal range and the like, is especially suitable for pest control on agricultural economic crops like vegetables, fruit trees and flowers, is safe, efficient, economical and environment-friendly, and has strong agricultural popularization and application value.

Description

technical field [0001] The invention relates to an insecticide, in particular to an insecticide compounded with capsaicin and Eupatorium adenophorum extract and a processing method thereof. Background technique [0002] Chemical insecticides have made great contributions to the control of pesticide pests, but at the same time, they have brought negative effects, not only causing serious resistance of pests, causing excessive pesticide residues in agricultural products, but also affecting the health of humans and animals, and destroying the ecological environment. Efficient and safe bio-pesticides and insecticides have become the development trend of the pesticide market, among which insecticides based on plant extracts have gradually become a research and development hotspot in the industry. [0003] Capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) is a hydrophobic, lipophilic, colorless, odorless, crystalline or waxy compound that produces pungent, burning Burning sensat...
