Filling research gaps to improve the management of Phytophthora root rot

Presenter: Dr. Gary Chastagner - Washington State University

Phytophthora root rot (PRR) can be a devastating disease for Christmas tree production resulting in high mortality rates of trees during any stage of production. Dr. Gary Chastagner presentation will provide information on the PRR life cycle, environmental conditions that favor disease development, damage that this disease causes to Christmas trees and discuss the tolerance of different tree species to PRR. Finally, Dr. Chastagner will provide preliminary results of fungicide research trials into prevention of PRR and future research options. Information presented will highlight research that has been supported by the Real Christmas Tree Board.
