Crabgrass and broadleaf weed control in turf using corn gluten meal based fertilizer
This study evaluates the efficiency of six different treatments of corn meal gluten fertilizer and a control in its ability to control the growth of crass grass, broadleaf and other grass weeds. Due drought stress and high temperatures the crabgrass took longer to emerge than anticipated. Double rate corn gluten meal fertilizer and dithiopyr were the only treatments to reduce the growth of crabgrass at 64 DAT. Overall higher rates of the corn meal gluten, and dithiopyr were seen to be very effective in controlling crabgrass growth. these treatment's were close to 100% effective by 116 DAT.
