| Abstract/Contents: | "In northern climates, bermudagrass (Cynodon dactylon (L.) Pers.) often succumbs to cold temperatures during winter. When overseeded with perennial ryegrass (Lolium perenne L.), effects of perennial ryegrass competition combined with winter decline can diminish bermudagrass density over time. These effects are especially evident in areas of bermudagrass growing in suboptimal environments such as shaded or poorly drained sites. Thus, chemical transition of bermudagrass is paramount in these environments. Studies on transition of overseeded bermudagrass in different growing conditions have not been previously reported. A two-year field study was conducted in 2003 and 2004 to determine the value of chemical transition with foramsulfuron (Revolverā¢) and characterize expected conditions when transitioning different areas of golf course fairways. Field experiments were conducted as randomized complete block designs with a 2 X 2 factorial arrangement of foramsulfuron rates and application timings and four replications. Each study was conducted on adjacent sides of a 'Vamont' bermudagrass fairway at Goodyear Golf Club in Danville, Virginia. Foramsulfuron was applied at 0.13 and 0.026 lb ai/A in early May and middle June each year. The trial area was overseeded with perennial ryegrass in the fall and applications were made the following spring each year. "Weak" stands, areas on a fairway that are thin in bermudagrass cover and are located under shade, and "strong" stands, areas located in full sun and thick in bermudagrass cover, were the two turf conditions tested on the fairway. Results indicated that foramsulfuron applied rate influenced perennial ryegrass control on "weak" stands of bermudagrass but not on "strong" stands. Reduced perennial ryegrass control forces 'Vamont' to compete with perennial ryegrass, thus limiting the growing season, growth habits, and overall health of bermudagrass. Bermudagrass reached 100% cover sooner when perennial ryegrass was treated in early May but reduced turfgrass quality resulted during the transition period. When treatments were applied in middle June, transition turf quality was improved but competition-free bermudagrass growing season was decreased. Data suggests that "stronger" stands of 'Vamont' bermudagrass can sustain a delay in foramsulfuron application without negative impact on midseason bermudagrass cover. "Weak" areas of bermudagrass have a better chance of recuperating from perennial ryegrass overseeding if treated early in the season but reduced transition aesthetics will result." |
