    Abstract:
    OBJECTIVE: To explore the preparation of 5% niclosamide ethanolamine granules and evaluate its molluscicidal effect. METHODS: 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. RESULTS: 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%. CONCLUSION: There is a high molluscicidal effect of 5% niclosamide ethanolamine granules and it is suitable for field application.
