Abstract

The present invention discloses a plant-derived photoactivation toxin insecticide, and relates to the technical field of chemical industry. The plant-derived photoactivation toxin insecticide comprises, by weight, 15-25 parts of alpha-terthiophene, 5-10 parts of furocoumarin, 10-15 parts of isoquinoline alkaloid, 1-5 parts of capillene, and 3-10 parts of Juxiangsu. According to the present invention, the ratio of each component is optimized, the prepared plant-derived photoactivation toxin insecticide has advantages of easy decomposition, no environmental pollution, safety on natural enemy, drug resistance generation resistance, is the natural product, and does not have toxicity or has low toxicity, wherein the toxicity of the plant-derived photoactivation toxin insecticide on pests is significantly increased by tens or thousands of times the original toxicity under illumination or near ultraviolet light illumination.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a plant-derived light-activated toxin insecticide. Background technique [0002] Photoactivated toxins refer to a class of compounds that originally had no or low biological toxicity, but their toxicity will be significantly increased under near-ultraviolet or visible light. For example, from a photochemical point of view, photoactivation should be a photosensitization process. It's just that photosensitization research involves a wider field, such as chemical synthesis, dyeing, etc., and photoactivated toxin is only one part of it. In addition, due to various reasons, the photosensitization reagent does not necessarily cause photoactivation toxicity. Photoactivation emphasizes the effect on organisms or biological macromolecules, so it is obviously different from the general photosensitization process in photochemistry. Contents of the invention [0003] The proble...
