通过氯硝柳胺乙醇胺盐可湿性粉剂喷粉法和喷洒法现场灭螺费用与效果分析，证明喷粉法操作简便，投入少，工作效率高，实用性强，具有不需水源、不受环境条件局限的喷施特点，2g／m2剂量杀螺效果满意，灭后15d可达到与喷洒法相同的杀螺效果。在4－5月实施更有利喷粉灭螺，掌握好喷粉时机可进一步发挥药效，在大面积易感地带灭螺具有明显的经济优势和较高的实用价值。
Through the niclosamide ethanolamine salt wettable powder spraying method and spray method on-site cost control and effect analysis, it proves that the powder spraying method has the advantages of simple operation, less investment, high working efficiency, practicability, no need of water source, Spraying conditions limited conditions, 2g / m2 dose snail satisfied with the effect, 15d off after the spray to achieve the same effect with the kill snail. In April-May to implement a more favorable pollination molluscum, mastering the timing of the pollination can further play a pharmacological effect, snail snail in a large area susceptible zone has obvious economic advantages and high practical value.
