EPPO Reporting Service (2006/060) : found in North Island in 2006 in 2 samples during a survey, under official control
EPPO Reporting Service (2008/186) : although P. kernoviae was first reported in 2006, tracing investigations revealed that it was likely to be present already in the 1960s. It was also found in soil samples from North Island.
McDougal & Ganley (2021): detected in foliage samples of Pinus radiata dated from 1986, 1999, 2000, 2002. The presence of P. kernoviae in pine foliage since 1986 suggests that P. kernoviae may be associated with physiological needle blight, a disorder of P. radiata with a previously unknown cause.
