Summary of the Express Pest Risk Analysis for Apiosporina morbosa
PRA area: Poland
Describe the endangered area: the entire PRA area
Apiosporina morbosa is a plant pathogen, which is the causal agent of black knot. It affects plants of the genus Prunus. The main host plants cultivated in PRA area are P. domestica, P. cerasus, more rarely: Prunus persica, Prunus salicina, Prunus armeniaca. The disease produces rough, black growths that encircle and kill the infested parts. Infected trees are stunted.
Rating of the likelihood of entry: Low
Rating of the likelihood of establishment outdoors and in protected conditions: Moderate (especially P. domestica – cultivated area 17.000 ha).The wild plants of the genus Prunus are also endangered.
Rating of the likelihood of spread: Low (because of inspection of consignments and using fungicides)
The most important phytosanitary measure is monitoring of imported plants of genus Prunus from area of agrophage occurrence.
It is necessary to prepare strategies and eradication measures in case of occurance Apiosporina morbosa in PRA area.
