Phytophthora: Training for Nursery Growers

Introduction

Certain species of Phytophthora - including sudden oak death, ramorum blight and rhododendron root rot - can devastate agricultural crops, nursery crops and forests, making Phytophthora disease the number one disease of nursery crops nationwide.

Phytophthora: Training for Nursery Growers, developed in partnership with the Oregon Department of Agriculture, provides information on Phytophthora and how to reduce the risk of Phytophthora disease in nurseries.

The course is divided into three modules, with review questions following each module: 

  • Biology, symptoms and diagnosis
  • Disease management
  • Phytophthora ramorum

Participants can stop and resume this 10-hour course at any time.
