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 2024 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 Diana Reyes, Bryan Mayjor, Larry Beutler, 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. Lucas, congratulations on landing the head distiller position. I will always love you both. 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, congratulations on graduating Stanford law school and passing the CA bar. Erin, so glad you have your own class room now. Lots of moves but they have all been in the right direction. Enjoy teaching those little ones. Love you all! – J. W. Pscheidt
