Has anyone out there used a corn gluten product for weed control? I hadn't heard of it until Mark mentioned it in a previous post. It apparently has a substance in it that inhibits root growth so the seed germinates but dies. My concern would be that it could inhibit the pumpkin root growth as well. Anyone growing big ones who uses it?

It did not seem to slow down lambsquarter or pig weed. $48.00 down the drain.

Rob:
I tried it on half of a 5,000 sq ft patch last year. It did suppress some emerging weeds for a couple of weeks as compared to the untreated. But after the first two weeks, really no difference between treated & untreated. Also, I noticed no difference in AG fruit growth between treated & untreated...

Corn Gluten works by attacking the first tiny hair roots out of any source. It is not selective to any weeds. What percentage of the pumpkins emerging hair roots does it get and how would you know?

I used some last year, and it seemed to help some. The Iowa State research that I read said that it kills off the newly emerging seedling roots. It is supposed to be more effective on smaller seeds than larger ones. It is also a 10% nitrogen source and is promoted as a weed and feed for lawns. It is supposed to help with crabgrass, with better results each successive year. I guess that it takes time to get the seeds germinated and killed off. It has to be applied twice per year, and at the rates it is used the nitrogen could grow 300 bushel corn. It might be too much nitrogen for pumpkins, but if you have tilled in lots of organic matter that is tying up the N, it might be helpful.
