Surveillance & Molecular Studies of Powdery Mildew Disease on Platanus orientalis: An Emerging Threat
Year: 2025
Type: article
Abstract: Powdery mildew is a significant foliar disease that affects a wide range of plant species globally, including Platanus orientalis(oriental plane tree). This study was undertaken to identify the fungal pathogen responsible for causing powdery mildew on P. orientalisin the Murree Hills, Pakistan. A comprehensive survey was conducted across various altitudinal zones, focusing on disease incidence. Symptomatic leaves were collected and analyzed on a morphological and molecular basis to characterize the causal agent, and pathogenicity tests were conducted to confirm their role in disease development. Microscopic and molecular examination revealed characteristic morphological features of Erysiphe platani, which was identified as the pathogen responsible. Pathogenicity was confirmed through the successful development of symptoms on healthy P. orientalisleaves, fulfilling Koch’s postulates. This study marks the first confirmed report of Erysiphe platanias a pathogen of P. orientalisin Pakistan, contributing to the existing knowledge on plant pathogens in the region. The findings provide a basis for future research on disease management strategies to minimize the impact of powdery mildew on P. orientalisand similar hosts.
