一种包覆印楝素缓释杀虫剂的制备方法
摘要：
本发明公开了一种包覆印楝素缓释杀虫剂的制备方法，属于杀虫剂制备技术领域。本发明是从印楝种子中提取印楝素，加入卵磷脂对其进行保护，以防止印楝素分解，提高印楝素的杀虫活性，再通过添加蒙脱石等物质对其进行改性吸附，再用壳聚糖、聚乙烯醇和明胶对其进行包覆制得包覆印楝素缓释杀虫剂。本发明的有益效果是：本发明通过在提取的印楝素中加入卵磷脂对其进行保护，防止了印楝素分解，提高了印楝素的杀虫活性，针对性强；所得产品杀虫活性高于其他产品16%以上，药效快，速效性和对害虫防治效果好。
摘要（英）：

The invention discloses a method for preparing an azadirachtin coated slow-release insecticide, and belongs to the technical field of insecticide preparation. The method comprises the following steps: extracting azadirachtin from azadirachta indica seeds, adding lecithin to protect azadirachtin from decomposing to improve insecticidal activity of azadirachtin, adding montmorillonite and other materials to conduct modified adsorption on azadirachtin, and coating azadirachtin with chitosan, polyvinyl alcohol and gelatin to prepare the azadirachtin coated slow-release insecticide. The method has the benefits that lecithin is added into the extracted azadirachtin to protect azadirachtin from decomposing to improve insecticidal activity of azadirachtin, and the pertinence is strong; the insecticidal activity of the obtained product is higher than that of other products by 16% or above, and the insecticide is quick in pesticide effect, fast-acting, and good in pest control effect.
