Laboratory trials of sodium 2.5 dichloro-4-bromophenol named B-2 for the molluscicidal effect against Oncomelania nasophora were carried out by Komiya's immersion technique. The values of LC50 of B-2 varied from 0.38 ppm to 0.54 ppm depending on the collection time of the snail. They were almost equal to those of NaPCP, but lower than those of Niclosamide. In the tests of toxicity to carp, rainbow trout and killifish, B-2 showed lower toxicity than NaPCP. Some aspects of mollusciciding application of the chemical were discussed.
采用小宫的浸泡技术，对名为B - 2的2,5 - 二氯 - 4 - 溴苯酚钠进行了杀灭钉螺（钉螺指名亚种）效果的实验室试验。B - 2的LC50值根据钉螺的采集时间在0.38 ppm至0.54 ppm之间变化。它们几乎与五氯酚钠的LC50值相当，但低于氯硝柳胺的LC50值。在对鲤鱼、虹鳟鱼和鳉鱼的毒性试验中，B - 2的毒性低于五氯酚钠。文中还讨论了该化学品在杀螺应用方面的一些情况。
