This study was carried out between the
years of 2009-
order to determine fungal agents that cause Esca and Petri diseases in
grapevine nurseries and in vineyards of Manisa, Denizli and Izmir provinces of
Aegean Region. It was planned to investigate the role and share of pathogens in
complex disease symptoms.
The trunk, cane and leaf samples were
taken from the grapevine nurseries, young and older vineyards. The isolations
from nurseries revealed the presence of Phaeoacremonium
aleophilum(Pm)and Phaeomoniella
chlamydospora (Pcl) as causal agents of Petri disease, based on their
morphological characteristics. The samples from young vineyards were infected
primarily with Pm, Pcl and secondly with Fomitiporia
mediterrenea (Fom), known as Esca pathogen, whereas the isolations from
older vineyards indicated primarily the presence of Fom followed with Pm and
Pcl.
In conclusion, the presence of the pathogens Pmand Pcl
causing Petri disease in the samples taken from grapevine nurseries was
revealed and it was also found that these pathogens were dominant in the
samples taken from young vineyards accompanied with Fom, causing Esca symptoms.
The vines in the older (10-25years old) vineyards were however infected mainly
with Fom and additionally with Pmand Pcl.
