The information in this handbook has been compiled from many sources. We sincerely appreciate the time and effort that everyone spent preparing and reviewing this material. Many of the past authors and contributors have been identified in the 2004 PNW Plant Disease Management Handbook, our 50th edition. Our attempt in this section is to identify all individuals who worked on the 2025 version of the handbook whether their effort was great or small. Those acknowledged as authors or contributors have written completely new sections or conducted major rewrites of existing sections. Reviewers helped read through and verify the existing information.

Special thanks go to Bryan Mayjor, Larry Beutler, Diana Reyes, and the rest of the folks in OSU Extension Communications who keep all the PNW handbooks moving along toward publication.

A personal acknowledgment from Jay to his family: Jacob, I hope the new business begins to do well and your throat feels better. Lucas (and Gabby), congratulations on your engagement. I will always love you all. To my wife Kim, the medical places are no fun but as your cook, chauffeur, manager, etc., I am with you every step of the way. Everyone is ready to help out. Ian, don’t work too hard as you know they say all work and no play…. Erin, I hope the moves to new schools calms down in the future. Enjoy teaching those little ones. Love you all! – J. W. Pscheidt
