Extract from Wikipedia article: Monilinia fructigena is a plant pathogen causing a fruit rot of apples, pears, plums, peaches and cherries.
Monilinia fructigena is a fungal plant pathogen that causes brown rot in stone fruits and other rosaceous plants. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to infect apple, pear, and plum trees, with the highest incidence of infection typically occurring in late summer and early autumn. The fungus is commonly isolated from decayed fruit and twig lesions, and its presence has been reported in various orchards and gardens throughout the region. Molecular analysis has confirmed the identity of M. fructigena isolates from this area, which exhibit similar genetic characteristics to those found in other parts of Europe.
The fungus Monilinia fructigena was observed on discarded apples at Belyi Naliv in Lembolovo, 35 miles north of Saint Petersburg, Russia on August 31, 2016. The fungus caused significant fruit rot, with the affected apples displaying characteristic symptoms such as softening and browning of the flesh. The observation suggests that M. fructigena is present in the region and can infect apple fruits, potentially leading to economic losses for local orchards. The fungus was likely spread through spores, which can be dispersed by wind, water, or insects. This sighting highlights the importance of monitoring and managing fungal diseases in apple production areas of Leningrad Oblast and north-western Russia to prevent the spread of M. fructigena and minimize its impact on fruit crops. Regular inspections and proper sanitation practices can help reduce the risk of infection.
