Organic Weed Killers / Pre-Emergent
Pre-Emergent Liquid Weed Killer
Alternative for Pre-Emerg or PREEM
Gluten-8™ is a novel selective pre-emergent natural herbicide that combines the effectiveness of 20 years of scientifically proven Corn Gluten Meal with the convenience and cheaper price of a sprayable liquid. The unique enzymatic hydrolysis process preserves the efficacy of Corn Gluten Meal to provide an economical organic product for home and professional pre-emergent weed control for suppression of annual grass weeds (crab grass) as well as broadleaf weeds such as dandelions, clover and plantain. Gluten-8 is all natural and is not comprised of toxic synthetic chemistries that is ideal for lawn care where pesticide bans exist.
