1、丘陵地区氯硝柳胺悬浮剂灭螺费用及效果研究摘要:[目的]了解25%氯硝柳胺悬浮剂(CN)在丘陵山区果园内灭螺效果,并进行成本-效果评价。[方法]选择宜兴市山丘地区2处有螺果园为试验现场,采用灭螺机喷洒的方法,实验组用CN按2.0g/�、对照组用50%氯硝柳胺乙醇胺盐可湿性粉剂(WPN)按4.0g/�喷洒灭螺,比较两组有螺面积下降率和活螺密度下降率;以有螺面积下降率和活螺密度下降率作为评价指标进行成本-效果分析。[结果]实验组用CN喷洒4次,灭螺后30d有螺面积下降率和活螺密度下降率均为100.0%,有螺面积和活螺密度每下降1个百分点的费用均为56.00元,分别优于对照组
2、WPN的�99.00%、92.25%和92.93元、99.73元。[结论]用CN山区灭螺,操作方便,成本低,灭螺效果好,具有良好应用前景。关键词:氯硝柳胺悬浮剂;钉螺;丘陵山区;费用-效果评价中图分类号:R184.38文献标识码:AEvaluationonthemolluscacidaleffectandthecost-effectivenessofsprayingsuspensionconcentrateofniclosamideintheorchardsinhilly10andmountainousareaWEIWen-xue1,YUANJian-fen1,CHE
