I was a master gardener several years ago and remember a encyclopedia type resource that OSU provided that you could look up plants and find disease info specific to that type of plant. I can seem to locate it on online but did see a catalog for $50. I was wondering if it is still available as a free resource?

Thank you for your inquiry. Our updated Plant Disease Handbook went online just today! It is available in print for $60 (plus shipping and handling), or you can search it online for free at: http://pnwhandbooks.org/plantdisease/
Have a great weekend!
