This presentation will focus on factors that cause winterkill, cultural practices such as fertilizer applications, sand topdressing, mowing height, core aeration, and the use of covers to minimize or prevent winterkill, and reestablishment techniques following winterkill. Preparing turf for winter extremes is a critical component to the golf course IPM program as a healthy turfgrass stand is more resistant to pest pressures the following year than a turf that has been weakened by winterkill injury. An update on the WinterTurf research project will provide attendees with the current state of knowledge on winterkill on cool-season turfgrass and describe novel approaches that are being used to identify new solutions to reduce winter stress injury.
