Jim T. Brosnan, Ph.D. Professor of Turfgrass Weed Science, The University of Tennessee, Knoxville, Tennessee
This seminar will provide an overview of herbicide resistance within Poa populations of golf course turf. There will be a focus on the current status of resistance in Poa populations of golf course turf. This will include different types of resistance, modes of action, downstream consequences and more. Attendees will learn how resistance can evolve as a result of weed management decisions made on the golf course and strategies to mitigate resistance within Poa populations on greens, tees and fairways.
