Abstract

Social forest nursery in Mysore district maintained by State Forest Department of Karnataka (India) was surveyed for the incidence of fungal diseases during 2011-2012. Incidence, severity and spread of the disease were recorded and fungal pathogens were isolated and identified. Forestry species raised in nursery bags includes Azadirachta indica, Bauhinia variegata, Cinnamomum verum, Dalbergia latifolia, Dendrocalamus strictus, Mangifera indica, Phyllanthus emblica, Pterocarpus santalinus, Pterospermum acerifolium and Tamarindus indica were found infected with foliage diseases. Some of the important pathogens include species of fungi belonging to genera Alternaria, Cercospora, Cladosporium, Colletotrichum, Helminthosporium, Oidium, Ravenelia etc. Seedling congestion and overcrowding often resulted in spread of foliar fungal pathogens. The study helped us to understand the incidence of fungal pathogens on seedlings in forest nursery of Mysore. Since seedlings grown in forest nurseries are the primary sources of planting stock, it is necessary to investigate the associated pathogens. There is a strong need for better understanding of these pathogens for developing effective management strategies
