I stumbled across this while researching. Perhaps it may help someone.

In this course, you will learn about Phytophthora so that you can reduce the risk of Phytophthora disease in your nursery. The course is divided into three modules: Module 1: Biology, symptoms, and diagnosis Module 2: Disease management Module 3: Phytophthora ramorum It is best to go through each module in order. Each module should take 1-2 hours to complete, although you may start and stop as often as you like. A glossary of scientific words is accessible from anywhere in the course. There are practice questions at the end of each module so you can test yourself on what you have learned. There are also links to further information. The course is free, but there is an optional online exam which you may take for $100. If you pass the test, you will receive a Certificate of Mastery on Phytophthora from Oregon State University Extended Campus. You will also be eligible for four credits of pesticide recertification credits through the Oregon Department of Agriculture.
