| Abstract/Contents: | "Patriot bermudagrass is one of the newer vegetative bermudagrass (Cynodon dactylon) cultivars and was released commercially in 2003. This cultivar is selected for its excellent winter hardiness, vigorous growth, early spring green up, spring dead spot resistance, and overall turfgrass quality ratings. Turfgrass managers are adopting this variety and information will be needed to aid weed control efforts during establishment. The effect of herbicides on Patriot growth and establishment is currently unknown. In addition new sulfonylurea herbicides are available that may improve weed control spectrum during sprig establishment. The objective of these studies were to determine weed control options for establishing sprigged Patriot and evaluate its response to various herbicides applied pre- and post sprigging. One field study was conducted in Blacksburg, VA to evaluate effects of the following herbicides on Patriot bermudagrass: oxadiazon (Ronstar™ 2G), quinclorac (Drive™), foramsulfuron (Revolver™), trifloxysulfuron (Monument™), metsulfuron (Manor™), MSMA, and 2,4-D + dicamba + MCPP + MSMA (Trimec™ Plus.) These herbicides were applied at timings relative to bermudagrass sprigging. The bermudagrass was sprigged on July 19th and oxadiazon (112 kg/ha and 168 kg/ha) and quinclorac (0.033 kg/ha and 1.12 kg/ha) treatments were applied on July 26th. Subsequent postemergence treatments were made on August 2nd consisting of foramsulfuron (1.8 L/ha), trifloxysulfuron (0.033 kg/ha), flazasulfuron (0.213 kg/ha), metsulfuron (0.067 kg/ha), foramsulfuron + metsulfuron, trifloxysulfuron + metsulfuron, and flazasulfuron+ metsulfuron. Applications of oxadiazon (168 kg/ha), flazasulfuron, and flazasulfuron + metsulfuron reduced coverage of Patriot to 40, 40, and 45%, respectively one month after sprigging. Otherwise, all herbicides were sufficiently safe for application to newly-sprigged Patriot bermudagrass. Late season bermudagrass cover ratings were equivalent between treatments or dependent on weed control. All sulfonylurea herbicides controlled large crabgrass, yellow nutsedge, hairy galinsoga, and barnyardgrass at least 90% except metsulfuron. MSMA and Trimec™ Plus controlled the four weeds at least 85% 6 WAIT." |
