Coniferiporia weirii

Summary of the Express Pest Risk Analysis for Coniferiporia weirii

PRA area: Poland

Describe the endangered area: The entire PRA area

Main conclusion

Coniferiporia weirii occurs in patches or centres of infection mostly as root rot. Pathogen may infect many conifer species in Europe. The main host plant is Pseudotsuga menziesii. Coast Douglas-fir occurs only in Pomerania and constitutes a relatively low proportion of mixed stands. C. weirii has A1 quarantine status for EPPOs. Fungus introduction and spread is prohibited in Europe. The most likely way of entry is import of infested seedlings, infected raw timber, logs, bark. Natural dispersal occurs slowly. The disease is hard to detect, because symptoms become apparent when the root system is in an advanced stage of deterioration. C. weirii is native North America, Japan and China species. The fungus may appear in PRA area, in case of similar climatic conditions.

Rating of the likelihood of entry: Low

Rating of the likelihood of establishment outdoors and in protected conditions: High

Rating of the likelihood of spread: Low (The main host plants are introduced and rarely grow in Poland. However C. weirii may infect many conifer species in EPPO region)

The most important phytosanitary measure is monitoring of imported plant material and wood from area where fungus occurs.

It is necessary to prepare strategies and eradication measures in case of fungus occurance in PRA area.

Curtobacterium flaccumfaciens pv. flaccumfaciens


Dendrolimus sibiricus

Summary of the Express Pest Risk Analysis for Dendrolimus sibiricus

PRA area: Poland

Describe the endangered area: mixed and pure stands of conifers

Main conclusions

White-lined silk moth presents a potential risk for forests in PRA area. Considering climatic conditions and the fact that conifers are commonly (almost 70% of trees) in Poland it is expected that pest will be able to establish and spread in PRA area.

If environmental resistance will be insufficient there is possibility of progressively establishment and forest damage.

All of phytosanitary measures and eradication methods should be used in case of pest occurrence in PRA area. Import of wood material is prohibited from non European countries so this way of entry is insignificant.

Wood or plants with larvae or eggs of D.sibiricus need to be destroy.

Dickeya dianthicola

Summary of the Express Pest Risk Analysis for Dickeya dianthicola

PRA area: Poland

Describe the endangered area: The endangered zone in which potential establishment of Dickeya dianthicola may have a significant impact is all areas of potato, tomato crops and ornamental plants such as cloves, hyacinths, dahlias, stonecrops.

Bacteria D. dianthicola has been detected three times in Poland in potato crops and there is a high probability that in the case of crop monitoring it could be detected again. There are no reports about the amount of damage caused by this pathogen that is why we should suppose, that as of today it is not a problem. There is a moderate probability that the bacteria will spread in potato crops. Spreading in greenhouse crops of decorative plants is less likely due to the controlled conditions for such crops. There are no anti-pathogen agent to directly combat the pathogen, the factor limiting occurrence and spreading is phytosanitary inspection of propagating material and compliance with hygiene rules in the place of cultivation.

The possibility of spreading the pathogen in clove growing is assessed as low due to the controlled growing conditions. Imported propagating material comes from places, where D. dianthicola was officially not found. There may be occasional infiltrations of the pathogen this way, but these will be a single cases. The higher risk is related to import of other decorative plants and potatoes. The uncertainty associated with the assessment of pathogen penetration scale with plant material is moderate due to the lack of official reports on the number of intercepts by this pathway.

The possibility of spreading in field crops is assessed as low due to the lack of reports on apperance of infected plants, with high uncertainty related to no literature data available. In greenhouse cultures the probability of pathogen spreading is defined as low, with low uncertainty.
