摘要：【中文】本申请涉及软体动物防治领域，更具体地，本申请涉及一种含有磷酸铁螯合物的环保杀螺剂及其制备方法。所述含有磷酸铁螯合剂的环保杀螺剂的制备原料包括磷酸铁螯合物、填充剂和水；所述填充剂包括玉米淀粉、小麦淀粉、大豆淀粉、木薯淀粉和磷酸酯双淀粉中的至少一种，优选为磷酸酯双淀粉。本申请提供的杀螺剂对人类和水生生物无害，对宠物和野生动物无害，同时能够改善磷酸铁在土壤中的溶解性，使其作为磷肥被作物吸收，既解决了磷酸铁在土壤中的降解残留问题，又给予了作物养分，保证了该杀螺剂对生态环境的无害性和安全性。本申请提供的杀螺剂解决了多数杀螺产品对鱼类等水生生物及野生动物有毒有害、残留高以及土壤降解差等环境生态污染的问题。 【EN】The application relates to the field of mollusk control, in particular to an environment-friendly molluscicide containing iron phosphate chelate and a preparation method thereof. The raw materials for preparing the environment-friendly molluscicide containing the iron phosphate chelating agent comprise the iron phosphate chelating agent, a filler and water; the filler comprises at least one of corn starch, wheat starch, soybean starch, cassava starch and phosphate ester distarch, and preferably the phosphate ester distarch. The molluscicide provided by the application is harmless to human beings and aquatic organisms, is harmless to pets and wild animals, can improve the solubility of the iron phosphate in soil, enables the iron phosphate to be absorbed by crops as a phosphate fertilizer, solves the problem of degradation residue of the iron phosphate in the soil, provides crop nutrients, and ensures the harmlessness and safety of the molluscicide to the ecological environment. The molluscicide provided by the application solves the problems of environmental ecological pollution such as toxicity, harm, high residue, poor soil degradation and the like of most molluscicidal products to aquatic organisms such as fishes and wild animals.
