First report of Monilinia fructicola in Bulgaria
In Bulgaria, symptoms of brown rot were noticed during surveys conducted in 2017 in the region of Plovdiv, in a small orchard of peach (Prunus persica) and nectarine (P. persica var. nectarina) trees. Numerous, greyish conidial pustules were observed on the surface of unripe and mature fruits. During summer 2018, similar symptoms were observed on cherry (P. avium) and plum (P. domestica) fruit in 2 additional orchards of the same region. Laboratory studies (PCR, sequencing, pathogenicity tests) confirmed the presence of Monilinia fructicola in diseased fruit (cherry, nectarine, peach, and plum). This is the first time that M. fructicola is reported from Bulgaria.
The situation of Monilinia fructicola in Bulgaria can be described as: Present, only in some areas (first found in 2017 near Plovdiv).
