I dont know. I didnt do a controlled comparison. sigh. at least it is also nice

I receive no compensation for running the Puregold list or Puregold website.
I do not run nor receive any money from the ads at the old Puregold site.
The chickens liked it. :)
As for seed germination... I'd have to give it a qualified maybe.
Perhaps I did not apply it heavy enough. Or perhaps it needed two or
three applications a month apart. I like to think it reduced the weeds,
but IMHO a good thick layer of mulch does a lot more.

You could get some ordinary corn meal. Then blindfold yourself, and
also blindfold your entire lawn. Then spread the cornmeal on half of
your lawn (randomly selected) and the corn gluten on the other half.
Voila! A Double-Blind study that should eliminate the placebo
Happy to be of help.
I too, was interested in this Corn Gluten hype, and to me that is what
it is. Last summer, after I harvested my melons, I took a 42"tiller
behind my tractor and tilled four rows sided by side 100 ft long. I
selected the rows randomly and treated them as follows: Row 1 I used
Treflan(this is what commercial growers use). Row 2 I did nothing,
Row 3, I used Preen(purchased at Walmart), and Row 4 I used Corn
Gluten. The Treflan and Preen rows had nothing germinate except a few
Bull-Nettle(probably from a root not a seed). The row I did nothing
too had several different kinds of grasses and weeds, including Lambs
Quarter, Rag Weed, white clover, Poor Joe and others. The row I used
the Corn Gluten in seemed (maybe) to have a little control of some of
the grasses, with no noticeable effect on the weeds, and not complete
control of the grass as the Treflan and Preen did.
Note: This was just Corn Gluten(not the one that has been processed
and sold as Organic Herbicide)--RFD

I have read that corn gluten works by promoting the growth of certain fungi
in the soil. These fungi suppress seed germination, but it takes more than
one year to develop a large enough fungus base to be effective. So a one
year test is not useful, and neither is a test in which the soil is dug each
year. Corn gluten is supposed to be effective on lawns when it is applied
for more than one year.
Evidentaly, we are reading different books.

One other thing to consider(at least I did): Corn Gluten Meal is a
byproduct of milling corn. What state is known for it's corn
production. Who would benefit most from finding a way to dispose of a
byproduct . Where was the study funded? Have you heard of anything
that didn't come out Iowa, directly or indirectly?

According to some experts:
"Corn gluten meal prevents sprouting seeds from developing normal
roots. This does not directly kill the seedlings, but makes them
susceptible to dehydration if the soil gets dry. Established plants are
See this entire article at Pesticide.org:
Apparently, several scientific studies have shown that this product
reduced the establishment of crabgrass in Kentucky bluegrass turf.
Applications of 20 pounds of corn gluten meal per 1000 square feet of
turf reduced crabgrass by about 60 percent. Perhaps it's not 100
percent, but it's safe for the environment.
