Corn As A Herbicide
A 5-year test by Iowa State University has proven that Corn Gluten Meal is very effective as an organic pre-emergent herbicide. Corn Gluten Meal is traditionally used as a high protein source for livestock, pets, and humans. However, amazingly enough, it is also deadly to emerging weed seeds. In fact, Corn Gluten Meal in University testing reduced Crabgrass emergence by a whopping 90%.
Corn Gluten Meal is proven effective against grassy and broadleaf weeds, cool season and warm season. Corn Gluten Meal is completely safe and also feeds your plants with 9% Nitrogen and 2% Phosphate plus assorted micronutrients. A-MAZING!
