摘要
为进一步验证溴乙酰胺(特杀螺)杀灭钉螺的效果,进行了现场灭螺实验,钉螺校正死亡率1.5mg/L 浸泡48h为100％;喷洒2.0g/m^2 7d为92.6％;沿边药浸2.0g/m 48h达100％。与五氯酚钠相比,溴乙酰胺的上述剂量在现场无论是浸杀,喷洒和沿边药浸的杀螺校正死亡率均高于五氯酚钠10mg/L浓度,显示该药具有较好的杀螺作用。
In order to test the molluscicidal effects of bromoacetamide, the experiments were carried out in the fields. Results showed that 100% of the bag-kept snails were dead when they were immersed in bromoacetamide with a concentration of 1. 5mg/L for 48 hours, when the drug was used as spray, the rate of snail death was 92. 6% with a concentration of 2g/m2 for 7 days, and when it was sprayed along the river bank accompanied by shoveling the grass with a concentration of 2g/m, the snails immersed in river water were 100% dead in 48 hours. The moiluscidal effect of bromoacetamide was better than that of NaPCP (at 10. 0mg/L). It is indicated that the bromocetamide is a promising molluscicides used in the field.
