First record of Monilinia fructicola in the Czech Republic
Until recently, only Monilinia laxa and M. fructigena were causing brown rot on stone and pome fruits in the Czech Republic, and M. fructicola (EPPO A2 List) had never been reported. During a survey carried out in summer 2006, 56 samples were tested for the presence of Monilinia species. M. fructicola was detected (isolation, PCR) in 15 samples from 11 locations in the western area (Bohemia) of the Czech Republic, mainly on peaches (Prunus persica), apples (Malus domestica), sweet and sour cherries (Prunus avium and Prunus cerasus), and rarely on ornamental trees such as flowering plum (Prunus triloba) and Malus × moerlandsii cv. ‘Liset’. In all cases, the pathogen was detected on fruits with one exception on a twig of P. triloba. M. fructicola was not detected on fruits of apricot (Prunus armeniaca) or pear (Pyrus communis) in 2006. These tested samples had been collected from orchards, private and public gardens. In 2007, the official survey continued. 80 samples were collected and 24 of these samples were found positive. M. fructicola was detected in fruits of apple, apricot, pear, peach, plum, sweet and sour cherries. This is the first report of M. fructicola in the Czech Republic.
The situation of Monilinia fructicola in the Czech Republic can be described as follows: Present, first found in 2006, under official control.
