Sažetak
Monilinia fructicola is considered the most aggressive Monilinia species on stone fruits worldwide. Until 2014 it was regulated as a quarantine pathogen in the European Union, but during the last 15 years it became obvious that it has established across Europe. In 2013 it was recorded for the first time in Croatia. To assess the potential impact and control of this new brown rot pathogen, development of pre-harvest and post-harvest brown rot was monitored during 2014 and 2015 in a peach orchard where integrated pest management measures are implemented. At the moment of harvest in 2014, brown rot incidence on fruits was 6.6 %. Out of 40 isolates collected, 27 % were M. fructicola, 30 % were Monilinia laxa, and 43 % were Monilinia fructigena. Twenty-one days after the harvest, Monilinia spp. developed on 73 % experimentally stored fruits. M. fructicola was identified on 28 % of fruits, while the rest were infected with M. laxa or M. fructigena. In 2015, the pressure of brown rot was very low and almost no fruits affected with brown rot were found at the moment of harvest. Twenty-one days after the harvest, Monilinia spp. was found on only 8 % fruits. M. fructicola was found on all fruits with brown rot symptoms. M. laxa was isolated from two fruits, and M. fructigena only from one fruit. Results are indicating that common measures against indigenous M. laxa and M. fructigena within integrated pest management on peach may be suitable for the control of invasive M. fructicola. It could be expected that all three Monilinia species on peach in Croatia shall commonly occur in mixed populations, and that the overall impact of M. fructicola on Croatian stone fruit production shall be relatively low.
