| Abstract: | Dried distillers grains (DDGS) is a by-product of ethanol production. An experiment was conducted to see whether this material might have weed suppression potential. The material contains 4% N, so it also has significant nutrient value. DDGS amended potting soil reduced emergence and growth of common chickweed and annual bluegrass. A mix with 20% DDGS nearly eliminated weeds. It also was phytotoxic to the crop. A surface mulch reduced the phytotoxicity and also the weed suppression. |
