Cornmeal gluten having at least 60% of protein in it are more effective for weeds. So, if you use plain cornmeal product, it will not be effective. Weeds like, crabgrass, purslane, foxtail, pigweed can be killed by it.

Along with mature plants, corn gluten meal cannot kill perennial weeds also, like, dandelions, quack grass, plantain etc. They will come back again and again as their roots survive under the soil during the cold season.
