Herbicide Resistance in Turf: An Emerging Issue Facing Golf Course Superintendents

Sept. 18, 2014
10 a.m. (Central)

Jim Brosnan, Ph.D.

Herbicide resistance is an emerging problem facing golf course superintendents in the transitional and warm-climatic zones. Repeated use of similar weed management strategies has given rise to herbicide resistant weeds, predominantly annual bluegrass (Poa annua) and goosegrass (Eleusine indica). In this 90-minute webcast, Jim Brosnan, Ph.D., will use case studies to illustrate the current status of herbicide resistance in turf. In addition, the benefits of herbicide rotation and diversifying weed management strategies to control problematic turfgrass weeds will also be discussed in detail.
