ABSTRACT
Objective To evaluate the molluscicidal effect of 2 kinds of shamingdan in lab. Methods Under constant temperature (25?1) ℃, the studies were carried out by using different concentrations(dosages) of molluscicide, shamingdan, in various methods of immersing, spraying and dusting power, and the molluscicidal effects were compared with 50% wettable powder of niclosamide ethanolamine salt(WPN). Results The 48-hour's LC_ 50(s) of 4% shamingdan granular formulation and 50% shamingdan soluble powder were 0.1752 mg/L and 0.2713 mg/L, respectively, which were similar to that of 50% WPN. In spraying and dusting powder experiment, the 7-day's LC_ 50(s) were 3.0418, 0.1623 g/m~2 and 2.8752, 1.1101 g/m~2, respectively, and the 50% shamingdan soluble powder was better than 4% shamingdan granular formulation and 50% WPN. Conclusions The molluscicidal effect of 2 kinds of shamingdan using immersing is better than that using spraying and dusting. The molluscicidal effect of the 50% shamingdan soluble powder is remarkably better than that of the 4% shamingdan granular formulation and 50% WPN.
