Gary, Take a look at the ingredient list for PREEN, please. What is in there besides corn gluten? I buy corn gluten several 55 gallon drums at a time and if that is all PREEN is I'll give my cattle feed a try as weed killer.

If the high protein content is what prevents the weeds from germinating what then prevents PREEN from interfering with desired seed germination or plant growth, or...?
