## Session Overview

Dr. Patrick McCullough delivers a comprehensive review of turfgrass weed management fundamentals paired with updates on herbicide resistance issues and new product introductions for the 2018 season. The presentation covers weed identification principles, the importance of cultural practices such as mowing height and irrigation management, and the science behind pre-emergent herbicide timing and activation. McCullough presents field and greenhouse data on widespread Poa annua resistance to dinitroaniline and sulfonylurea herbicides across Georgia, demonstrating how combining modes of action can restore control. The session concludes with previews of new products including halauxifen-based herbicides (RELZAR, Game On, Switchblade), Vexis, Solero, Dismiss NXT, and Coastal.
