Re: CULT: corn gluten meal herbicide

The things I learn from you folks!

Kitty, try googleing for allelopathy and corn meal.

From the web:

<......We ["we" is Nick Christians, Iowa State University] patented corn
gluten meal in 1991 as a natural pre-emergence herbicide for use on all
crop areas. Numerous distributors presently market it nationwide under a
variety of trade names (a complete list of sources is available via the
internet at http://www.hort.iastate.edu/gluten/cframe.html). .....>
........................
<Further work in the 1990s has resulted in the isolation and
identification of six organic compounds from corn gluten meal that have
the ability to inhibit root formation of plants at the time of
germination. These  compounds are patented, as is a sprayable form of
corn gluten meal.  However, neither the sprayable material nor the
active components are presently on the market. > [yet]
