摘要
目的观察氰胺化钙杀灭钉螺的效果。方法室内和现场浸杀均设25、50、80mg/L3组,浸杀1、2、3、5、7d后计算钉螺死亡率。室内喷洒和现场喷洒、喷粉均设10、30、50g/m23组,计算施药1、3、7、15d后钉螺死亡率。实验均设50%氯硝柳胺乙醇胺盐可湿性粉剂和清水对照组。结果室内氰胺化钙25mg/L浸杀7d,50mg/L浸杀5d,钉螺死亡率均为100.00%。室内喷洒氰胺化钙30g/m21d、10g/m23d,钉螺死亡率均为100.00%。氰胺化钙25、50、80mg/L现场浸杀5d,螺袋内钉螺死亡率分别为84.00%、96.00%、100.00%。30、50g/m2现场喷洒15d,钉螺死亡率分别为74.15%和73.12%。30、50g/m2现场喷粉15d后,钉螺死亡率分别为81.11%和96.03%。结论氰胺化钙属慢性杀灭钉螺药物,浸杀和喷洒钉螺死亡率均高于氯硝柳胺常规对照组,喷粉灭螺具有同样效果。
Objective To evaluate the effectiveness of calcium cyanarnide on snail control Methods In the immersion experiment, calcium cyanamide powder was divided into 3 groups with concentrations of 25, 50, 80 mg/L in laboratory and field, respectively, and the death rates of snails were investigated in 1, 2, 3, 5, 7 days. In the spraying experiment, calcium cyanarnide powder was divid- ed into 3 groups with concentrations of 10, 30, 50 g/m^2 in laboratory and field, respectively, and the death rates of snails were investigated in 1, 3, 7, 15 days. In addition, niclosamide ethanolamine salt （50%） and fresh water were as the control Results In the immersion experiment and in the laboratory, the death rates of snails were 100.00% in 5-7 days, and in the field, the death rates of snails were 84.00%, 96. 00%, 100. 00% in the concentrations of 25, 50, 80 mg/L in 5 days, respectively. In the spraying experiment and in the laboratory, the death rates of snails were 100. 00% in 1-3 days, and in the field, the death rates of snails were 81.11%, 96.03% in the concentrations of 30, 50 g/m^2 in 15 days, respectively. Conclusions Calcium cyanamide is one of slow-release molluscicides, and its molluscicidal effect is higher than that of niclosamide ethanolamine salt.
