Abstract
OBJECTIVE: To investigate the molluscicidal effect of 5% niclosamide ethanolamine granules against Oncomelania hupensis in a marshland field. METHODS: The 5% niclosamide ethanolamine granules were sprayed at a dose of 40 g/m2 on 3 snail-breeding marshlands in Yangzhong City of Jiangsu Province to assess its field molluscicidal actions, while 26% suspension concentrate of metaldehyde and niclosamide (MNSC); at a dose of 4 g/m2) and fresh water served as controls. RESULTS: After seven days spraying, 5% niclosamide ethanolamine granules resulted in a of snail mortal85.42%ity, while the mortality rates of snails were 82.35% and 2.86% in the MNSC and water control groups, respectively. CONCLUSION: 5% niclosamide ethanolamine granules exhibit a high molluscicidal activity, which is suitable to be used in the mashland.
