溴乙酰胺在浓度1ppm时,不仅有明显的杀螺效果,且具有较强的杀灭螺卵作用,但现场灭螺时,如施药后突降大雨,将使药液浓度下降,而影响近期杀螺效果。为了解此条件下药物的远期效果,我们观察了经低浓度溴乙酰胺浸泡后仍存活的 Bromoacetamide at a concentration of 1ppm, not only has a clear snail effect, and has a strong role in the fight against spiro eggs, but snails on the scene, such as sudden drops of heavy rain after application, will make the liquid concentration decreased, and the impact Recent kill snail effect. To understand the long-term effect of the drug under this condition, we observed that it survived the soaking with low concentrations of bromoacetamide
