Abstract/Contents:"Overseeding of bermudagrass (Cynodon dactylon L.) with perennial ryegrass (Lolium perrene) can be both rewarding and problematic. Fraze mowing offers a new tool that can be used in both perennial ryegrass establishment and removal. The objective of our study was to determine the most effective timing of fraze mowing for perennial ryegrass establishment and removal; as well as to compare fraze mowing to other methods currently established. The overseeding treatments were performed three times during the fall to remove or disturb bermudagrass growth. The methods used were fraze mowing, scalping, and vertical mowing followed by perennial ryegrass seed application. The removal treatments were performed four different times during the spring. The methods used were fraze mowing, scalping, and application of glyphosate and rimsulfuron. Measurements were taken weekly to evaluate the performance of the treatments both visually and through standard turfgrass evaluation devices. Results of our fall overseeding study found fraze mowing provides a faster establishment of perennial ryegrass, however by 15 March all treatments were visually the same. The 31 October treatment showed the slowest establishment as the perennial ryegrass did not have an optimum number of growing degree days to develop density. Fraze mowing treatments for ryegrass removal in mid-March and early-April, left the plots with minimum bermudagrass coverage. The overseeding fraze mowed end-May had a quicker green up of bermudagrass. The glyphosate application only stunted the ryegrass growth in mid-March and early-April but severely damaged both ryegrass and bermudagrass in mid-May. The rimsulfuron, slowly killed a large amount of the perennial ryegrass. The herbicide treatments displayed a limited amount of bermudagrass development in the mid-March and early-April. Repeated scalping was also effective in promoting bermudagrass development. Control treatments displayed no visual bermudagrass cover until after mid-May. Overall, late-May fraze mowing resulted in the best bermudagrass cover 5 weeks after treatment."
