First report of Phytophthora kernoviae in Chile


Surveys for the presence of Phytophthora species in forest trees were conducted in May and December 2012 in Southern Chile. Fallen leaves of Drimys winteri (Winteraceae) showing necrosis around the midrib were observed in a native evergreen forest near the city of Valdivia, Región de Los Ríos. Symptomatic leaves from the litter or still attached to the plants were collected and tested in the laboratory for the presence of Phytophthora spp. The presence of Phytophthora kernoviae (EPPO A2 List) was confirmed (morphology, sequencing, pathogenicity tests) in fallen leaves of D. winteri collected from the surface litter. This is the first time that P. kernoviae is reported from Chile.
The situation of Phytophthora kernoviae in Chile can be described as follows: Present, first detected in 2012 in fallen leaves of Drimys winteri in a native forest (Valdivia, Los Ríos region).
