Abstract/Contents:"Improvements in the quality of seeded bermudagrass (Cynodon dactylon) varieties are making seeding a high quality bermudagrass turf more realistic. Weed control during the establishment phase of any plant is a major issue for success. A study was conducted to examine the pre- and post- emergence herbicide tolerance of newly selected 'Princess' bermudagrass, with focus on the establishment phase. For the post-emergence herbicide study, dicamba, diclofop, 2,4-D, MSMA, clopyralid, metsulfuron, and quinclorac were applied at recommended rates at 1 week after emergence (1 WAE), 2 WAE, and 4 WAE. Percent injury was collected after each herbicide application along with percent cover and above ground biomass at the end of the study. In a study of pre-emergence herbicides, 'Princess' bermudagrass was established with a seed drill on 30-cm centers and a 2.5 cm band of activated charcoal was applied over the top of the seed row to deactivate the herbicides. Charcoal banding has been used in the turfgrass seed industry for many years as a way of protecting seed rows from pre-emergence herbicides. Diuron, prodiamine, and oxadiazon were applied at recommended rates immediately after planting. Visual injury ratings were taken after emergence, percent cover was taken weekly, and above ground biomass was taken at the end of the study. Data on herbicide injury and plot establishment will be discussed."
