【摘要】 目的观察5%杀螺胺乙醇胺盐颗粒剂的江滩现场杀螺效果。方法在江苏省扬中市选择3块有螺江滩,采用5%杀螺胺乙醇胺盐颗粒剂40 g/m2喷撒法灭螺,以26%四聚·杀螺胺悬浮剂4 g/m2和清水为对照进行对比观察,统计比较现场杀螺效果。结果喷撒7 d后,5%杀螺胺乙醇胺盐颗粒剂组钉螺死亡率为85.42%,26%四聚·杀螺胺悬浮剂组为82.35%,清水组为2.86%。结论 5%杀螺胺乙醇胺盐颗粒剂杀螺效果较好,适合在江滩现场应用。更多还原

【Abstract】 Objective To investigate the molluscicidal effect of 5% niclosamide ethanolamine granules against Oncomelania hupensis in a marshland field. Methods The 5% niclosamide ethanolamine granules were sprayed at a dose of 40 g/m2 on 3 snail-breeding marshlands in Yangzhong City of Jiangsu Province to assess its field molluscicidal actions,while 26% suspension concentrate of metaldehyde and niclosamide(MNSC);at a dose of 4 g/m2)and fresh water served as controls. Results After seven days spraying, 5% niclosamide ethanolamine granules resulted in a of snail mortal 85.42% ity,while the mortality rates of snails were 82.35% and 2.86% in the MNSC and water control groups,respectively. Conclusion 5% niclosamide ethanolamine granules exhibit a high molluscicidal activity,which is suitable to be used in the mashland.更多还原
