Re: Pre-Emergent Herbicides

Hi Viktoria,
     I have heard of corn gluten as a pre-emegrent but not of how well it
works. You're the first person I've heard having experience with it. Does it
perform as well as Surflan and Treflan? The latter do a very good job,
eliminating the vast majority of annual weeds. As long as they are not used
to excess they are pretty safe for everything but small roots.
