(And they are considered trade secrets by the EPA and therefore do not legally need to be disclosed.) The surfactants and other so-called 'inert' ingredients in such chemical herbicides appear to be far from inert-or innocuous. Relyea used actual Roundup purchased at retail, it wiped out massive numbers of frogs, toads and other amphibians. But in real life the active ingredient is never used alone, and when Dr. Rick Relyea, the active ingredient in the herbicide 'Roundup' (glyphosate) was found to be relatively innocuous to the amphibians he studies. When tested by University of Pittsburgh researcher Dr. What are your thoughts on this? Literally hundreds of acres are affected. Pulling is tricky as the celandine produces little tubers along their roots that can stay behind. However the size of our area would require a major grant to purchase the amount we'd need. I understand that the glyphosate in the Roundup is not severely evil. It was recommended that we use Roundup in February before the natives come up. But the over 2000 beautiful spring natives we've put in are being choked by a thick blanket of lesser celandine that flourishes during the peak bloom of such natives as Dutchman's Breeches, Virginia Bluebells, Trillium and Trout Lilies. We are in the process of restoring a Lehigh River bank with native plants.
