Pest-resistant protectant used on surface of lotus leaf and preparation method thereof

Abstract

The invention discloses a pest-resistant protectant used on the surface of lotus leaf and a preparation method thereof. The pest-resistant protectant is prepared from the following raw materials: n-hexane, ethyl ether, dysphania ambrosioides, flos daturae, fructus xanthii, melia azedarach fruit, croton tiglium fruit, bamboo bar, guinalphos, triazophos, deltamethrin, ethanol, octylphenol polyoxyethylene and water. According to the invention, natural pest-resistant plants are used, and an organic solvent extraction mode is adopted. During the process, many modern technologies such as freeze-drying, vacuum distillation and the like are adopted to reduce loss of active ingredients as much as possible during the extraction process, and chemical antibacterial pesticide raw medicines with high efficiency are mixed to finally prepare an emulsion. Thus, dosage of chemical pesticides is greatly decreased.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insect-resistant protective agent used on the surface of lotus leaves and a preparation method thereof. Background technique [0002] The leaf surface of the lotus leaf is covered with "small mountain buns" close to each other. The "hill buns" are covered with fluff, like dense vegetation on the mountain, and a steamed bun-shaped "blockhouse" grows on the top of the "hill buns". convex top. Therefore, the depression of the "mountain bag" is full of air, so that an extremely thin nano-scale air layer is formed on the clinging leaf surface. Since rain and dust are no different from giants to these microstructures on the lotus leaf surface, when rain and dust fall, they can only be compared with the "blockhouse" on the "small hill" when they fall, separated by a layer of nano-air. "The convex top constitutes a contact of several points, which cannot be further "i...
