Phytophthora, derived from Greek and meaning "plant destroyer," is among the most destructive plant pathogens worldwide. But what exactly is it? Phytophthora is a genus of fungi-like organisms called oomycetes, or water molds, responsible for a wide range of plant problems including wilts, cankers, blights, root rots, and even mortality in severe cases. It can be found impacting plants in both forests and urban settings with notable species including P. cinnamomi (root rot), P. infestans (potato blight), and P. ramorum (sudden oak death). This webinar will cover Phytophthora biology, its impacts, and potential management strategies.
