摘要

Brown rot caused by Monilinia fructigena is a major disease of pome and stone fruits, but its occurrence on loquat (Eriobotrya japonica) has been rarely documented. In this study, brown rot symptoms were observed on loquat fruits in orchards in Bartın province, Türkiye. Morphological characteristics and molecular analyses, including rDNA-ITS sequencing, confirmed the causal agent as M. fructigena. Pathogenicity tests verified that the isolate could infect loquat fruits and produce typical brown rot symptoms, fulfilling Koch’s postulates. Inoculation trials also demonstrated that the isolate may pose a risk to other economically significant members of the Rosaceae family, such as apricot and apple. This represents the first report of M. fructigena-induced brown rot on loquat in Türkiye, expanding the known host range of the pathogen and highlighting the importance of monitoring and early disease management to prevent potential outbreaks.
