April 2014 The autochtonous taxa of the genus Prunus L.: Prunus × fruticans, Prunus × fechtneri and Prunus × dominii was chosen for this research: the phenological observations and occurrence pest and diseases. We recorded, that two of studied taxa P. × fruticans and P. × dominii started the first growth phases and P.× fechtneri the last. The longest vegetation period from first phenophase to dormancy (224 days) for P.× fechtneri in 2012 was observed. The shortest vegetation period (209 days) from first phenophases to phenophases flowering for P. × fruticans in 2013 was observed . We recorded the occurrence of insect Cydia funebrana , parasitic lichen Xanthoria parietina and fungal disease Botrytis cinerea . The highest incidence of Cydia funebrana on taxa P.× fechtneri from the locality Bádice and Prunus × dominii from the locality Dolné Lefantovce was recorded. On the shoots of the taxa L2, L3 and P1 the presence of parasitic lichen Xantoria parietina and on the plum P.× fechtneri B fungal disease Botrytis cinerea was observed. Only for the taxa Prunus × fruticans L1 no lichen was recorded. The taxa Prunus × fruticans L1, P1 and Prunus × dominii L2, L3 no fungal disease was show.
