Abstract/Contents: | "Improved cold tolerance of 'Patriot' Bermudagrass (Cynodon dactylon) has increased the desire to convert cool-season athletic fields to bermudagrass in the transition zone and northern states. The goals of this experiment were to evaluate pre-planting vegetation-management treatments as they affect the establishment of row- planted Patriot bermudagrass and to determine if a cool-season turf can be converted to bermudagrass in a manner that minimizes effects on turf use. Trials were conducted at the Virginia Tech Turfgrass Research Center in Blacksburg, VA and Bridgewater College near Harrisonburg, VA in 2006. In 2007, the trial was repeated at the Virginia Tech Golf Course in Blacksburg. On May 19, 2006 and May 17, 2007, four pre-planting treatments were applied to the cool-season turf, which was a mixture of Kentucky bluegrass (Poa pratensis) and perennial ryegrass (Lolium perenne). These four treatments were: nontreated control, partially kill existing veget ation in 5 cm-wide strips on 15-cm centers using glyphosate at 4.5 kg ai/ha in 561 L/ha carrier volume, completely kill existing vegetation using glyphosate at 4.5 kg ai/ha in 280 L/ha, and regulate existing vegetation with trinexapac ethyl at 0.39 kg ai/ha in 281 L/ha. On May 26, 2006 and May 24, 2007 Patriot bermudagrass was sprigged at a level of 430 sprigs/sq m. Visual estimations of percentage total cover of green turf and bermudagrass establishment, and quality ratings were made periodically. Results from these three trials indicate that totally killing the cool-season turf or partially killing turf in strips results in a quicker conversion to bermudagrass. However, turf quality and percentage of total ground cover are sacrificed up to 10 weeks after planting when totally killing existing turf. Nontreated and trinexapac ethyl resulted in similar bermudagrass establishment rates of 50 to 80% after 10 weeks. An advantage to these treatments is that total ground cover never dropped below 90% and turf could remain in use the entire time. Partial-kill plots were similar in that turf cover was at least 70% for the duration of t he study and could sustain moderate field use. Although sprigged bermudagrass can be rapidly establish ed after killing existing vegetation, our results indicate that higher turfgrass quality can be maintained by row-planting bermudagrass sprigs directly into existing turf. Partially killing existing turf can substantially speed establishment while maintain ing acceptable turf quality. Trinexapac ethyl and the nontreated plots ma intained the highest turfgrass quality with the slowest, but acceptable, establishment rate." |
