烟酰苯胺(Nicotinanilide)经实验性灭螺和小面积现场灭螺证实,是一种高效低毒的灭螺新药~[1]。我们于1985年7月在嘉鱼县百里长渠进行了烟酰苯胺大面积喷洒灭螺效果的观察。该渠建于1961年,全长54230m,上宽14m,深4m,底宽5m,坡斜45°。主要引三湖连江水(非疫水)灌溉农田。如遇干旱,则启用长江干堤上的立新闸、双益闸引江水灌溉,致使外滩钉螺向渠内扩散。1983年首次在长渠的群光闸段发现了钉螺,由于未能采取有效措施,
Nicotinanilide is proved to be a high efficiency and low toxicity drug for snail-killing by experimental molluscicide and small area on-site snail elimination [1]. In July 1985, we conducted a large-scale spraying of snailide anilide against molitrix in the Longji Canal in Jiayu County. The canal was built in 1961, a total length of 54230m, width 14m, depth 4m, bottom width of 5m, inclined 45 °. Mainly cited the Three Lakes Lianjiang water (non-flood) irrigation farmland. In case of drought, the new gate on the drywall of the Yangtze River was activated and the water was irrigated at Shuangyi Gate, causing the snail on the Bund to spread to the canal. Snail was found for the first time in 1983 in the Quanguang Gate of the Changqu Canal. Due to the failure to take effective measures,
