What you are likely seeing is a product consisting of corn gluten meal. It has some preemergent qualities, but it is important to understand that how well it works depends greatly on your climate and the weather you have. It also is fairly short lived, acting from 4-5 weeks, maybe 6 weeks max. It is also a fertilizer. A search for corn gluten meal on Gardenweb or Google will give you plenty of opinions.

jayk thanks so much you saved me a bundle, i did the research and asked at feed store, bought 50 pound sack of corn gluten, for $3.95. Gardens alive charges $44.oo for a 40 pound bag + shiping they call it granulated WOW. maybe the wow stands for how much profit they are making. thanks again iam so glad i asked.

Can you share the location? I need to buy some as well.

Thanks

Rue, there is a difference between Corn Gluten Meal and Corn gluten feed. CGM has about 60% protein and the pre-m effects you are wanting.
