Specifically which turf chemicals are "death on them" and have been shown to hurt animals that feed on worms from "treated" lawns? I see birds eating worms on golf courses all the time. 2,4-D is probably the most common herbicide used on turf and I think it is approved for direct application to ponds.
You are correct about the modern chemicals. I repeated what I had heard my father say. He was correct, old treatment wiped out everything and for a long time. Modern stuff, except sevin, doesn't wipe everything out.
