Hi Chris, it's basically a mild disinfectant, anti fungal,but also keeps the birds lice free,a lot of gardeners use it when growing tomatoes,i think they use it to keep fungal probs away,not too sure on that though,i've used it for some 50 + years.Might be better things on the market but they won't be cheaper.
One thing for sure if you have any problems with your feet ,athletes foot ,stinking.I'll guarantee this stuff WILL stop it.
