The peach story
One of the most important postharvestdiseaseof peaches is brown rot caused by different species of the fungusMonilinia.Anamorphs dominate as inoculum sources especially in theMediterranean areas ofEurope, where brown rot in peaches is caused byM. laxaandM. fructigena. A third species,M. fructicolacauses brown rot in other parts of the world and is included in the A2 list of quarantine organisms for Europe (organisms present in the EPPO region, but contained, under official control) because its broad dissemination in Europe would be devastating especially for peach and nectarine. These fungi overwinter and produce mycelium in fruit mummies and infected wood. This produces conidia under favorable conditions or from stromata that produce ascospores in the case ofM. fructicola. Fruit infection by conidia ofMoniliniaspp. can occur secondarily from any infected tissue in which the moisture content is sufficient for sporulation. When the microclimate is unfavourable, infections may remain latent until conditions favour disease expression, which finally leads to fruit rot. Correlation between the incidence of rotting and latent infection caused byMoniliniaspp. has been reported. Management of orchards focused to decrease postharvest brown rot will be treated here. Detection and identification methods, inoculum sources, and epidemiological factors affecting latent fruit infections and postharvest brown rot will be described, together with the models available to predict disease risk. Different integrated control strategies will be presented.
