A survey on olive decline in Croatian Istria
The phenomenon of partial or total decline of olive trees in Istria in 2016 and 2017 was investigated within this research. In the field, visual examinations and collection of samples of plant material were carried out to determine the cause and causal agents of olive trees decline. Survey and collection of samples included 23 locations within four olive growing hills (areas of Buje-Umag, Poreč-Vrsar, Rovinj and Vodnjan-Pula). The locations differed microclimatic, agrotechnically, according to olive varieties and different trees’ ages. A total of 78 isolates of phytopathogenic fungi were collected. Identification of species was performed by conventional methods (cultivation, analysis of isolate morphology), and by molecular diagnostic methods (PCR and sequencing). According to the results of the examination and analysis of collected samples several species, genera and families of phytopathogenic fungi were identified. The most commonly isolated species associated with symptoms of partial or total decline, weaker growth and vigor of olive trees was the species Verticillium dahliae Kleb. In addition to this species, fungi from the family Botryosphaeriaceae, the species Armillaria mellea (a causative agent of white root rot) and several other fungal species were also found. According to the geographical distribution of the pathogens, V. dahliae and A. mellea species were found in all olive growing hills on the Istrian peninsula covered by this work. The presence and distribution of these phytopathogenic fungi can represent a serious problem in olive growing in Istria.
