Turf Weeds was developed to provide weed management information and newsearch reports to turfgrass managers.  This site contains information on weed identification, chemical and cultural management of weeds, and current topics relevant to weed management in lawns and professional turf.  Turf Weeds was created  by Dr. Shawn Askew, Assistant Professor of Turfgrass Weed Science at Virginia Polytechnic Institute & State University.

Abstract:

Many sports turf managers desire to convert cool-season grasses to cold-tolerant seeded bermudagrass (SB).   However, seedling establishment is limited by competition with existing turf.   Two field studies were conducted in Blacksburg, VA to evaluate methods of establishing Riviera SB into a Kentucky bluegrass (KB) golf fairway maintained at 2 cm height with minimal effects on turfgrass aesthetics.   Treatments included killing 5-cm wide strips or tilling 10-cm wide strips spaced every 25-cm, treating KB with trinexapac ethyl three times at weekly intervals prior to seeding, killing existing KB with glyphosate, and not treating KB prior to seeding.   When assessed at 2 wk after seeding from 10 m away and perpendicular to killed and tilled strips, turfgrass quality (1-9 scale) in stripped plots (6.3) was not decreased compared to the nontreated plots (6.5).   In fact, killed strips were not evident when viewed looking down the fairway, even from this close distance.   However, when viewing from the same distance parallel to strips (across the fairway), turf quality was 3.3 and 6.2 in stripped and nontreated plots, respectively.   Complete cover of killed KB by SB took just over 4 wk.   Stolon production of SB occurred 3 wk after seeding.   Initial data indicates that strip killing would be a viable method of establishing SB without limiting play on desired turfgrass.
