Liquid Corn gluten meal is a water-soluble weed pre-emergent derived from corn gluten meal. Patented and tested for over 20 years by Iowa State University as a pre emergent pesticide, hydrolyzed corn gluten proved to be as much as four times more active than corn gluten meal on target weeds in experiments.
Hydrolyzed Corn Gluten gluten meal offers a non-toxic, yet effective, alternative to chemical-based weed and feed products for weed control in lawns and gardens. Lawnbright Weed Wipeout prevents crabgrass from developing roots when applied correctly.
