Abstract

Fraze mowing offers a new tool used in both overseeding establishment and removal of perennial ryegrass (Lolium perenne L.). Research objectives were to determine the most effective timing of fraze mowing in overseeding establishment and removal, as well as to compare fraze mowing to other establishment and removal methods. Fall overseeding studies suggest that fraze mowing and scalping in mid-October provides the fastest establishment of ryegrass. However, by mid-March all treatments led to visually similar results. When evaluating removal timings, fraze mowing performed in early- and late-May led to faster visual bermudagrass recovery than March and April timings. Early-season application of glyphosate for ryegrass removal was fairly ineffective; whereas, late-season application was damaging to bermudagrass. Rimsulfuron removed ryegrass more quickly late in the season. Repeated scalping gradually removed ryegrass providing a slower, but complete, bermudagrass recovery. Overall, late-May fraze mowing resulted in the best bermudagrass cover 5 weeks after treatment.
