| Sumario: | In the Mediterranean basin area, powdery mildew disease on hazelnut is commonly caused by Phyllactinia guttata. The disease occurs in late summer-autumn causing limited damage or economic impact. In April 2021, an unusual outbreak of the disease was observed on lower leaves of hazelnuts (cvs, Negret and San Giovanni) leading to rapid leaf desiccation in two commercial orchards (Camí de la Serra and Mas de la Coma), both located at La Selva del Camp, Tarragona, in north-eastern Spain. Unlike P. guttata, roundish spots of white mycelium appeared on the adaxial side of the leaves (Figure 1). Fruit was also infected and damaged. |
