Abstract
Weeds and herbicide resistant weeds are the single greatest barrier farmers in the dryland cereal grain cropping region of the Inland Pacific Northwest face in today’s agriculture and is a large threat to conservation tillage moving forward. I have dedicated a large portion of my time to providing and facilitating research and outreach to this significant challenge farmers face. In my region, downy brome (Bromus tectorum) resistant to Group 2 and Group 9 herbicides is the biggest issue; however, my program is focused on the larger problem across eastern Washington. My efforts include using the WSU Wilke Research and Extension Farm and large-scale research to ‘show-and tell’ farms how they can economically use a long-term cropping plan to get multiple effective herbicides onto the ground, and how to use targeted tillage to enhance winter annual weed control for an integrated approach. My program is also looking at biological weed control for enhanced long-term control in a series of large-scale demonstrations across the dryland wheat producing region of Adams County. This barrier farmers face will truly take a combination of chemical, physical and potentially biological methods to maintain economically viable winter wheat production. Over the last two winter grower meeting seasons I have presented trial results and WSU Wilke Farm experiences at 37 meetings to over 2,200 participants and have started to see adoption of these practices.
