Abstract
Litsea deccanensis is a commercially important tree, distributed in South India and Sri Lanka. The seedlings raised in the nursery were found infected and wilted. The disease incidence rate was recorded nearly 40%. The fungus was isolated from the disease sample and grown on PDA. The same fungus was re-isolated and identified from diseased stems after the pathogenicity test, which showed the pathogenic behaviour of the isolated fungus, thus fulfilling Koch's postulates. Based on cultural and morphological characteristics followed by molecular analyses (ITS and TEF1), the pathogen was identified as Clonostachys byssicola (Bionectriaceae). This communication is the first report of C. byssicola causing seedling wilt in L. deccanensis from the Southern Western Ghats, Kerala, India.
期刊介绍：
Australasian Plant Disease Notes is an international journal for publication of short reports from all countries which describe original research that transcends national boundaries. All aspects of plant pathology are covered including new geographical records of diseases or pathogens, new pathogens or pathogen strains, taxonomic papers, quarantine notes, disease management and diagnostic methods. Australasian Plant Disease Notes is a publication of the Australasian Plant Pathology Society.
