Q.corn meal gluten as herbicidal pre-emergant
This may sound silly. I used to find a product in our local garden centers that was pure corn meal gluten. I cannot remember its maker/brand. It was usually stocked near the Preen, but was touted as organic and cost a good deal less. This product has vanished from the shelves. My question is this: would corn meal or corn meal flour purchased at the grocery store work as an herbicide in the same manner?
It vanished from the shelves because it didn't work.
