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 further verify the effect of bromothyramide on killing snails, the oncomelania test was conducted on the spot. The corrected mortality of snail was 1.5 mg / L for 48 h, which was 100%. Spraying 2.0 g / m ~ 27 d was 92.6% Along the edge of the drug dip 2.0g / m 48h up to 100%. Compared with sodium pentachlorophenate, the above doses of bromoacetamide in the field regardless of immersion, spraying and along the edge of the snail cure mortality were higher than pentachlorophenol sodium 10mg / L concentration, indicating that the drug has better The kill effect.
