Macdonald Creeping bentgrass (DLFPS-AP/3018 or AP-18) is a versatile creeping bentgrass appropriate for greens, tees, and fairways. Named for Charles B. Macdonald who is considered the Father of Golf Course Architecture, a cultivar named for him should demonstrate superior performance. Developed by DLF and Rutgers University, Macdonald enables golf courses to be maintained with lower inputs and yet produce a superior product. Macdonald was developed for high resistance to many diseases including Dollar Spot, Anthracnose, Brown Patch and Pink Snow mold.
