Insecticide compound drug-loaded microsphere for honeysuckle and preparation method thereof

Abstract

The invention belongs to the technical field of insecticides, and discloses an insecticide compound drug-loaded microsphere for honeysuckle and a preparation method thereof, the compound drug-loaded microsphere contains a compound synergistic composition, and the compound synergistic composition is any one of 16% thymol. Beta-caryophyllene, 17% beta-caryophyllene. Matrine or 13% trans-cinnamyl aldehyde. Azadirachtin; and the preparation method of the insecticide compound drug-loading microspheres comprises the following steps: preparing hollow silicon dioxide microspheres HMSN; preparation of amino modified hollow silicon dioxide microspheres NH2-HMSN; and preparation of the beta-caryophyllene / matrine@ NH2-HMSN drug carrying microspheres. The aphid killing activity of a single agent is enhanced through compounding, the slow-release drug-loaded microspheres are prepared by using the hollow silicon dioxide microsphere loaded compound agent, the fast-acting property, the slow-release property and the persistent effect of preventing and treating honeysuckle aphids are improved, drug release can be matched with the aphid occurrence rule, and the effect of inhibiting aphid population growth is achieved.

Description

technical field [0001] The invention belongs to the technical field of insecticides, and in particular relates to an insecticide compound drug-loaded microsphere for honeysuckle and a preparation method thereof. Background technique [0002] At present, Lonicera japonica Thunb. is one of the bulk medicinal materials, and its high-quality and efficient cultivation is particularly important for the development of the Chinese medicine industry. Pests and diseases occur frequently during the planting of honeysuckle, among which aphids are one of the most common and most harmful pests, with strong fecundity, prominent overlapping of generations, and periodic parthenogenesis. Aphids live by sucking honeysuckle juice, causing leaves and flower buds to turn yellow and even fall off. The honeydew secreted will cause leaf sooty disease, reduce the photosynthesis of honeysuckle, and seriously affect the yield and quality of honeysuckle. [0003] Honeysuckle is a commonly used traditio...

AI Technical Summary

Problems solved by technology

[0005] (1) In the process of preventing and controlling aphids, chemical pesticides account for a large proportion. Due to unreasonable use, problems such as pesticide residues, pest resistance, and soil and water pollution have been caused; however, botanical pesticides have slow onset of effect and poor performance in practical applications. Disadvantages such as short duration and single dosage form

[0006] (2) There are few types of existing plant-derived substances, low yields, and high application costs; compared with chemical pesticides, plant-derived substances have shortcomings such as single active structure, slow onset of action, and greater influence by natural factors. The application rate is low; at the same time, the mechanism of plant-derived insecticides is not clear at present, and the number of registered products is small and the variety is single

[0007] (3) The existing technology has made remarkable achievements in the research and development of new dosage forms such as screening of plant-derived insecticides, synergism and nano-sustained release agents, such as 3.6% nicotine-matrine microcapsule suspension and 3% Microcare, etc., but There is no such research report on the control of honeysuckle aphid
