Organic Pre-Emergent Weed Control That Works
A Different Approach to Weed Control
Lawnbright's organic pre-emergent is a natural herbicide that combines the effectiveness of 20 years of scientifically proven Corn Gluten with the convenience of a sprayable liquid.
Scientifically Proven Results
The University of Iowa's Department of Horticulture conducted extensive research and determined that corn gluten meal can reduce crabgrass cover by up to 86% and improve turfgrass quality when applied correctly.
Quick and Easy Application
This is not spot treatment: it’s easy to apply by simply spraying the treatment on through your hose, and will take 10 to 20 minutes, depending on the size of your lawn. Early spring application reduces hand pulling through the season.
Safer for Kids, Pets and the Planet
By using an organic Corn Gluten formula instead of harsh chemicals and carcinogenic weed killers, Lawnbright provides a solution that is safer for your family, pets and the planet.
