Abstract/Contents: | "Southern crabgrass (Digitaria ciliaris) is a common weed found in St. Augustinegrass (Stenotaphrum secundatum). New regulations and loss of registered herbicides have greatly limited postemergence control options for crabgrass. Alternative materials that have shown weed control properties are being studied for effectiveness, including sodium bicarbonate and cinnamon. The company Garden Weasel is marketing the product Crabgrass Killer, which is a mixture of cinnamon and sodium bicarbonate. Greenhouse and field trials were conducted in the spring and summer of 2009 to evaluate the effectiveness of sodium bicarbonate for controlling crabgrass, as well as tolerance in St. Augustinegrass. Four rates of Crabgrass Killer were applied (244, 488, 977, and 1465 kg/ha), and one rate of sodium bicarbonate (1465 kg/ha). Both trials compared two crabgrass growth stages, 1 to 2 leaf and 1 to 2 tiller. Greenhouse studies at the 1 to 2 leaf stage showed moderate crabgrass control at all rates 7 days after treatment (DAT), with control >80% at higher rates of Crabgrass Killer (977 and 1465 Kg/ha). Control at 1 to 2 tiller stage crabgrass ranged between 13% and 43%. In field trials, crabgrass control was between 40% and 75% at both weed stages for all treatments 7 DAT. Turfgrass injury 7 DAT was >20% for all treatments when Crabgrass Killer was applied to crabgrass at the 1 to 2 leaf stage. Less injury to St. Augustinegrass (<20%) was observed 7 DAT when Crabgrass Killer was applied to crabgrass at 1-2 tiller stage. While sodium bicarbonate offered moderate control of crabgrass in both greenhouse and field trials, injury to St. Augustinegrass could limit future consideration for use." |
