Abstract

Podosphaera, a genus of powdery mildew fungi, poses a significant threat to various economically valuable plants by causing characteristic white or grayish mildew, which can severely impact crop yield and plant health. In this study, we characterized Podosphaera species infecting Epilobium aitchisonii, Filipendula ulmaria, and Nepeta cataria in Battagram (Khyber Pakhtunkhwa), Fairy Meadows (Gilgit Baltistan), and Leepa Valley (Hattian Bala, Azad Jammu & Kashmir), Pakistan, respectively. Morphological examination and phylogenetic analysis based on the ITS region of ribosomal DNA identified the causal agents as Podosphaera epilobii, P. filipendulae, and P. macrospora, which are new records for Pakistan. While P. filipendulae is already known to infect Filipendula ulmaria in Europe, this study represents its first record from Pakistan. Additionally, P. macrospora, previously reported mainly on Saxifragaceae, is documented here for the first time on Nepeta cataria (Lamiaceae), expanding its known host range. These findings highlight the importance of monitoring and managing powdery mildew infections to mitigate their impact on economically important plants across different regions of Pakistan.
