Currently, Botrytis cinerea is a significant disease that affects berries in Peru. It is a pathogen that attacks multiple organs and different phenological stages of the plant. Therefore, strategies involve the application of various active ingredients. However, there are reports of active ingredients that are generating variability in this pathogen within the same field in Peru, as they are not focused on its sensitivity to fungicides based on their chemical groups. The objective of this study was to determine the efficacy of seven fungicides at discriminatory doses and evaluate the utility of different molecular markers to characterize its genetic diversity. Eight isolates from different blueberry-producing regions were morphologically and molecularly characterized using phylogenetic analysis of four markers. Morphological characterization did not show differences among the isolates. Molecular characterization was performed by DNA amplification, and the ITS gene sequence showed limitations in genus identification. Therefore, nuclear genes G3PDH, HSP60, and RPB2 were used, confirming the identification of the isolates as Botrytis cinerea. In vitro, no differences were found between PDA and MEA media for fludioxonil, while differences were observed for the fungicides thiofanato-methyl, pyraclostrobin, iprodione, and fenhexamid when using PDA and MEA media. Additionally, a difference in sensitivity was found in YBA medium compared to PDA medium for boscalid and fluopyram.
