If what they say about Glyphosates is true, there will be no residue. I also beleive that an acre or so in a food plot won't affect the food sources for turkeys, quail, etc. It may be a problem where a person is doing 100's of acres, but most of us don't live in Texas. My 4-quarter acre plots is a drop in the bucket on my little 100+ acre farm. And that is about the size for most of us on this board. Different locales call for different applications.
