摘要
目的 评价氯硝柳胺乙醇胺盐粉剂杀灭钉螺效果。方法 采用泥盘接触法进行4%氯硝柳胺乙醇胺盐粉剂室内撒粉杀螺试验,以及现场撒粉试验,同时以50%氯硝柳胺乙醇胺盐可湿性粉剂喷洒进行灭螺效果的平行比较。结果 实验室杀螺试验表明,粉剂撒施与可湿性粉剂喷洒杀螺效果相似;现场试验显示施药后3d粉剂撒施灭螺效果低于可湿性粉剂喷洒,而7d后两种剂型和方法的杀螺效果差异无显著性。结论 氯硝柳胺乙醇胺盐粉剂撒施灭螺效果与可湿性粉剂喷洒灭螺效果相当,适用于水源缺乏地区和水位难以控制地区灭螺,具有显著的实际应用价值。
Objective To evaluate the molluscicidal effect of niclosamide ethanolamine salt clustable powder (DP). Methods A comparative molluscicidal experiment was carried out by spraying method with niclosamide ethanolamine salt 4% DP. The experiments were respectively done in the labatory and field. The spraying with niclosamide ethanolamine salt 50% wettable power (WP) was used as the control. Results The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were similar in the laboratory. In the field, the effect of niclosamide ethanolamine salt 4% DP was lower than that of 50% WP in 3 d. However, the molluscicidal effects of the two formulations had not significant difference after 7 d. Conclusion The molluscicidal effects of niclosamide ethanolamine salt 4% DP and 50% WP were almost the same. DP is suitable for some areas where water are lack, or the water level are difficult to control.
