We need Kelly to weigh in on this thread.
I understand that it is the surfactant in Roundup that causes the problem...but an 85% kill rate for amphibians, whatever the cause, is not something I want at my pond. This year, for the first time, I have noticed a stunning population of frogs and didn't figure out why until just now...no Roundup in the past 18 months. Before that, absolutely no frogs, tadpoles, etc. in a pond treated "carefully" by Roundup.
burgermeister,
I think this is more than a greenpeace issue...I think it is real. Missing frogs for three years are my evidence. Do you know for sure that Ortho brush killer is labeled for use around ponds? If so, I will try it, if not, no thanks.
