    Why Tree Diseases Are So Difficult to Manage


    Infectious tree diseases are sometimes difficult to understand and manage, especially relative to how they differ from insect infestations and non-infectious tree diseases. This talk will focus on the unique aspects of infectious diseases and why they are so difficult to manage, including the fact that pathogen inoculum is microscopic when infections occur, and the fact that infections can be latent for days, weeks, months and years before symptoms develop. We will use case studies and profiles of key historic, emerging, and threatening tree diseases to elucidate the difficulties of plant health management for infectious diseases.
