Crabgrass and Broadleaf Weed Control in Turf Using Corn Gluten Meal Based Fertilizer
Five experimental corn gluten meal based fertilizers were tested and compared to an industry standard and a control plot to observe its control of infestations of crabgrass and broadleaf weed. The experimental corn gluten meal fertilizer was effective in controlling the weed population by 88%. However, the control of the experiential product was not statistically different from the industry standard that saw control of 97-99%. All treatments failed to provide significant control over plantain, chickweed, dandelions, birdsfoot, clover, or trefoil.
