|a Botrytis cinerea on grapes causes bunch rot at both pre- and postharvest stages, in which losses can reach up to 100%. Chemical control primarily relies on the prophylactic use of site-specific fungicides. Repeated applications of these products raise the risk of fungicide resistance development in B. cinerea populations, which can result in disease control failures. To determine the extent of resistance, B. cinerea isolates were collected from grape clusters in the northwest and southwest grape growing regions of Michigan in 2014 and 2018 (n = 115 and 125, respectively). These isolates were phenotyped using discriminatory doses of eight fungicides to determine the levels of resistance. Fungicide resistance increased from 2014 to 2018, mostly affecting the active ingredients fenhexamid, fluopyram, and iprodione. B. cinerea isolates resistant to multiple fungicides were detected in 2014 and 2018, with a higher frequency of resistance in 2018. TaqMan real-time PCR has been developed to detect B. cinerea fungicide resistance to fenhexamid and to differentiate the erg27 F412S/I/V alleles. The TaqMan assay was tested for sensitivity, specificity, and reproducibility on purified DNA and infected grape tissue samples. Our data provide essential information to growers about the efficacy for B. cinerea control using the available botryticides. Furthermore, the developed fenhexamid markers will be transferred to diagnostic clinics to assist growers in the management of bunch rot before resistance-related control failures occur
