Not sure how plausible it would be to spread it after seeds have germinated though....
Its the scale , not the timing that is a killer. Lots of things are put on crops after germination, but to spread gluten as a weed inhibitor over a 100 acre plot (small by todays stabndards) you would probably need gluten from about 1000 acre's of corn.
Works great on flower beds when we have millions of tons of corn harvested every year, but to use it back on the fields? Totally impracticle due to scale issues. Add in the fact that when you are a little bit hungry you can eat and digest the stuff as food and in a food shortage future their won't be any to spare anyhow.
