Participants of the 7th IUFRO Phytophthora Working Group (November 10-14, 2014, Esquel, Patagonia, Argentina) attending presentations at Los Alerces National Park. Participants observed native forest sanitary problems, including the mortality of Austrocedrus chilensis affected with mal del cipres caused by Phytophthora austrocedri .

Panoramic view of Los Alerces National Park where the mortality of Austrocedrus chilensis affected with mal del ciprés is observed. The disease was first detected in the area in 1935, and it was attributed to different causes. Many decades after, in 2005, the cause was attributed to Phytophthora. photo by Gloria Abad – USDA-APHIS-PPQ
