磷化锌的灭鼠效果,在开始使用的一、二年里,无论是在小型试验或大面积使用时,都此较好;更因它价格低廉,使用方便,一经试用,即深受群众欢迎,因此,在不到十年的时间里,已成为国内使用最广的灭鼠药。但是,近两年来,在使用历史较长的地区,反映磷化锌的效果愈来愈差的报告日益增多。有人认为,这是因为家鼠对磷化锌产生了耐药性;也有人怀疑,磷化锌的含量是否较以前低。
The anti-mouse effect of zinc phosphide, in the first year or two started to use, both in small trials or large-scale use, it is better; more because of its low prices, easy to use, once tried, that by the masses Welcome, therefore, in less than a decade, has become the most widely used rodenticide in the country. However, in the past two years, there has been an increasing number of reports showing that the effect of zinc phosphide is getting worse in areas with a long history of use. Some people think that this is because the house mouse is resistant to zinc phosphide; others suspect that the zinc phosphide content is lower than before.
