A field trial in Egypt of the plant molluscicide, Ambrosia maritima is described. Applications of 140, 70 and 35 mg/l-1 dry, whole plant were made to irrigation canals and drains in June. The treatment effect took between 1 and 5 weeks to become fully established. The reduction in the numbers of alive Biomphalaria alexandrina snails was generally more than 90% and was virtually the same at all treatment levels and in both types of watercourse. The snail population remained at a low level for at least 3 months until September-October. The possible use of a single, annual application in April or May in controlling snails throughout the main schistosomiasis transmission season in Lower Egypt is suggested.
本文描述了在埃及对植物杀螺剂海蓬子进行的田间试验。6月，将140、70和35毫克/升干全株施用于灌溉渠道和排水沟。处理效果需要1至5周才能完全显现。亚历山大双脐螺存活数量的减少通常超过90%，在所有处理水平和两种水道类型中几乎相同。直到9月至10月，蜗牛种群数量至少3个月保持在低水平。建议在4月或5月单次施用，以控制埃及下埃及主要血吸虫病传播季节的蜗牛。
