The presentation will cover how Downy brome (Bromus Tectorum L.) has become more challenging to control in winter wheat (Triticum aestivum) cropping systems across the western state, including Washington, Idaho, Oregon, California, Montana, and Colorado. Over the last twenty-plus years, wheat growers have relied heavily on Group 2 herbicides that include many trade names like Maverick, Olympus, Osprey, Olympus Flex, PowerFlex, and Beyond for downy brome control. With repeated applications over time, growers are reporting less efficacy and the need for multiple applications.
