With increased environmental concerns, Organic lawncare has been a hot topic and Corn gluten has been a favorite application for those seeking organic lawn care. 

Corn gluten has no post-emergent effect on killing broadleaf weeds. Claims have been made that corn gluten prevents weed seeds from germinating, but only after repeated heavy applications (20 pounds per 1,000 sq. feet) for several years and may be more based on the nutritional factor of adding Nitrogen than having herbicidal quality.   The use of Corn gluten can be very expensive, requires repeated applications, is labor intesive, and is difficult to apply.  It’s heavy application requirements can also be very messy and lead to increased runoff.
