Abstract
In December 2022, a leaf spot and blight disease was observed in Eucalyptus plantations in northern India. Morphological features coupled with phylogenetic analysis of combined internal transcribed spacer (ITS), translation elongation factor 1-alpha (tef1) and β-tubulin (tub2) regions confirmed the association of Pseudoplagiostoma eucalypti with the disease symptoms. The pathogenicity of P. eucalypti was first proved on detached leaves of Eucalyptus camaldulensis and reconfirmed in glasshouse inoculation experiments. Finally, Koch's postulates were fulfilled by re-isolating the pathogen from the inoculated leaves. This pathogen was first described in 1995 from the leaves of Eucalyptus spp. collected from southern India, and this study confirms its first serious occurrence after more than two decades in northern India. In addition, this is the first report on the polyphasic characterization of P. eucalypti from India.
期刊介绍：
This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English.
Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
