The dirtdoctor, Howard Garrett, an organic super gardener has long recommended cornmeal gluten as an organic pre emergent. www.dirtdoctor.com

I have used reg cornmeal tea for PM on squash with success but never tried it on toms. One cup in a thick sock in a gallon of water. Strain into hand pump spray bottle. Apply as needed and the powdery mildew is halted.

I bought a 50 pound bag at the feed store for $7 or $8 dollars and have sprinkled the pellets around. Some weeds were already coming up and those are still there but I do notice weed suppression. When wet, the pellets break up. The worst problem I had was my dog wanting to eat it. The cat vomited something the color of this product so I think it found the bag in the shed. Both animals are fine; it is a feed for cattle but my animals are little pigs.

From what I've read, Corn Gluten only suppresses germination of seeds, it won't suppress seed that has already germinated. For plants that are already growing, it acts a high nitrogen fertilizer.
Then there are other studies that dispute it's effectiveness as a pre-emergent herbicide.
Never used it myself, so I can't confirm it's effectiveness one way of the other.

In pellets, that would be squirrel food here. I have to glue down
Sluggo with plaster to keep them from eating that, and they will
still sometimes sneak up and eat a bunch of it before the plaster
dries. (I need iron phosphate in a sticky gel, like Deadline, instead
of in handy squirrel food sized pellets that also tend to disappear
into the mulch, making them completely useless in that case
even if the squirrels do not eat them.)

I used it last year. with good results. I put in on the ground when I planted my onions, but it doesn't last all summer, probably should reapply in 6 weeks.
Mine was ground fine, not pellets.
