Summary of the information used for the evaluation |
Possibility that the pest could become associated with the commodity The pathogen is not known to be present in the Zhenjiang province, but it is reported from a neighbouring province. However, the presence of suitable telial hosts in the immediate surroundings of the nursery (within 1.5 km) combined with the long dispersal range of aeciospores and uredospores makes the infection of the commodity by means of basidiospores possible. The pathogen may go undetected during inspection before export because an asymptomatic period of at least 6 months has been reported. Measures taken against the pest and their efficacy Fungicide treatments (most of active ingredients are systemic) are expected to reduce the likelihood of infection of the pathogen and the rate of colonisation of needles. The official inspections during production and before export are expected to have some effects in detecting the pathogen. However, an asymptomatic period of at least 6 months is reported during which infection cannot be detected visually. Interception records In the EUROPHYT/TRACES‐NT database, there are no records of notification of Pinus parviflora and P. thunbergii bonsai plants neither from China nor from other countries due to the presence of Coleosporium eupatorii between the years 1995 and May 2021 (EUROPHYT/TRACES‐NT, online). Shortcomings of current measures/procedures No relevant shortcomings.
