Corn gluten is a by-product of wet milling process to make cornstarch. It is an animal feed for cattle, poultry, other livestock, fish and some dog foods. It also contains naturally occurring substances, which inhibit the growth of seed's tiny feeder roots by causing a break down in the cell wall. The seedlings struggle to get enough moisture, which causes them to die before they ever have a change to take hold. When used as directed, corn gluten acts as a preemergent natural herbicide that will not harm beneficial insects, soil organisms, pond or stream life. It is also safe around pets and children. Since corn gluten kills only the roots of sprouting seeds, it can be used around transplants and established vegetables, flowers, fruit, shrubs and lawns. It can be used even up to the day of harvest. Once vegetable or flower seedlings have true leaves, it is then safe to apply corn gluten. Apply 10-20 lbs. per 1000 square feet in the Spring & Fall for pre-emergent protection. This Corn Gluten Meal is granulated and easy to apply with a spreader.
