Upcoming workshops are listed below. You can also find archived webinars on our presentations page.

  • The Phytophthora Online Course: Training for Nursery Growers is currently available online. (details)

    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. You will also be eligible for four credits of pesticide recertification credits through the Oregon Department of Agriculture.

    The 2017 edition of the California Nursery Conference is coming to Southern California in July! We are excited to bring to you presentations of 15 researchers from across the nation speaking about water issues in nursery and greenhouse production. This group is part of the USDA Clean WateR3 project studying numerous aspects of water including irrigation efficiency, capture and reuse, and treatment. The group also include economists and sociologists studying the costs of production and how growers use information in the decision making process. Take a look at the program here. We hope to see you at the Conference in Irvine!
