Summary of the information used for the evaluation |
Possibility that the pest could become associated with the commodity Pinus parviflora is a confirmed host of the pathogen. The pathogen is present in the province and suitable hosts, including P. parviflora, are present in the surrounding of the nursery. The pathogen could enter the nursery and spread within the nursery mainly by spores disseminated by rain/wind and by contaminated pruning tools. Infected plants may remain asymptomatic hampering a prompt detection of the pathogen during inspections. Measures taken against the pest and their efficacy The fungicide treatments are expected to reduce the rates of infection. Interception records In the EUROPHYT/TRACES‐NT database, there are no records of notification of Pinus parviflora and P. thunbergii plants neither from China nor from other countries due to the presence of Pestalotiopsis disseminata and P. microspora between the years 1995 and May 2021 (EUROPHYT/TRACES‐NT, online). Shortcomings of current measures/procedures Inspections are mainly devoted to plants displaying symptoms. As plants infected by the pathogen could remain asymptomatic for a long period of time, in order to detect the presence of the pathogen laboratory analysis would be necessary.
