In June 2020, a leaf spot caused by Neopestalotiopsis sp. in Indiana strawberry production was confirmed to be the same disease recently found in Florida strawberry production. Differences in cultivar susceptibility were observed in the field. Greenhouse trials using either bare-root or plug plants were conducted to explore possible differences in host resistance to the foliar phase of the disease caused by Neopestalotiopsis sp. Clear differences in cultivar susceptibility were observed. Florida Brilliance, Florida Sensation, Camino Real, and Florida Radiance were among the most susceptible cultivars evaluated in these trials. Several short-day cultivars including AC Valley Sunset, Darselect, Earliglow, Flavorfest, Galetta, Honeoye, Jewel and Sonata remained asymptomatic in the trials. Since the above-mentioned asymptomatic short-day cultivars are commonly used in matted row systems typical of Indiana strawberry production, future field trials with the matted row system may demonstrate that the foliar phase of the disease caused by Neopestalotiopsis sp. may be less common in Indiana than in other areas of the US.
