thats not the only one starting to show resistant plants there is starting to be a few plants that are becoming resistant to roundup I read this some where it was a peice of research from one of the colleges just don't remember which one.

The LD-50 is a very limited statistic, and it can be used in misleading ways. Round-up is very toxic to frogs, tadpoles, and other amphibians.

No link here (newbee) - but plenty of info on documented environmental problems from roundup can be found by searching.

They've removed the big 'Biodegradable' from the bottom of their label for a reason.  :roll:
