To explore the preparation of 5% niclosamide ethanolamine granules and evaluate its molluscicidal effect.
The optimal formula was obtained by the selection of wetting agents, dispersants, adhesives and carriers. The molluscicidal effect of 5% niclosamide ethanolamine granules was measured by the spray methods in the laboratory and field.
The mixed 5% niclosamide ethanolamine, 0.2% sodium lauryl sulfate, and 1% alkylphenol sulfonic polyxyethylene ether sulfonate were crushed by gas flow, and then mixed with 93.7% quartz sand and 0.1% polyvinyl alcohol water solution, drying to 5% niclosamide ethanolamine granules. The density, bulk density, and moisture of 5% niclosamide ethanolamine granules were 1.4 g/ml, 1.3 g/ml, and 2.4%, respectively, and the hot storage stability was qualified. Under the lab condition, the death rates of Oncomelania hupensis snails sprayed with 0.5 g/m2 (7 d) or 1.0 g/m2 (1 d) of 5% niclosamide ethanolamine granules were higher than 95%. In the field, the death rates of the snails sprayed with 0.5 g/m2 (7 d) or 1.0 g/m2 (1 d) were higher than 85%.
There is a high molluscicidal effect of 5% niclosamide ethanolamine granules and it is suitable for field application.
探索5%氯硝柳胺乙醇胺颗粒剂的制备方法并评价其杀螺效果。
通过对润湿剂、分散剂、黏合剂和载体的筛选获得最佳配方。采用喷雾法在实验室和现场测定5%氯硝柳胺乙醇胺颗粒剂的杀螺效果。
将5%氯硝柳胺乙醇胺、0.2%十二烷基硫酸钠和1%烷基酚聚氧乙烯醚磺酸盐混合后经气流粉碎，再与93.7%石英砂和0.1%聚乙烯醇水溶液混合，干燥制成5%氯硝柳胺乙醇胺颗粒剂。5%氯硝柳胺乙醇胺颗粒剂的堆密度、松密度和水分分别为1.4 g/ml、1.3 g/ml和2.4%，热贮稳定性合格。在实验室条件下，用0.5 g/m²（7天）或1.0 g/m²（1天）的5%氯硝柳胺乙醇胺颗粒剂喷洒钉螺，死亡率高于95%。在现场，用0.5 g/m²（7天）或1.0 g/m²（1天）喷洒钉螺，死亡率高于85%。
5%氯硝柳胺乙醇胺颗粒剂杀螺效果好，适合现场应用。
