CROP DISEASES are outcome of interaction of crops and pathogens favoured by environment and are visualized as symptoms or signs in the crops. Orchids comprised fascinating and attractive floriculture crop known for its flowers with unique shapes, colours, forms, fragrances, and long shelf life. Commercially, orchids are cultivated as potted plants for aesthetic purpose and cut flowers for market demand (NRCO, 2015). India is native to 1256 orchid species comprising of 155 genera (Singh et al., 2019). The Himalayas, the NorthEast region, and Western Ghats are the hot spot regions for orchid distribution. Arunachal Pradesh leads in orchid diversity with 612 orchid species followed by Sikkim with 560 species and Darjeeling hills of West Bengal with 479 species (Singh et al., 2019). Orchids are cultivated in controlled polyhouses for commercial purpose under which favourable environment for bringing out the crop is maintained. These favourable parameters also assist in the development of insect pests and diseases which bring about quantitative and qualitative loss to crops. Knowledge of diseases is pre-requisite to bring effective management. Some new diseases are on reports, minor diseases are becoming major with more threat to yield and host range of pathogens is getting widened. Eukaryotic fungi, prokaryotic bacteria, and living intermediate viruses cause many diseases in orchids thereby bringing down their yield potential. With a view to compiling orchid diseases reported so far, the present communication reports the review on current status of orchid pathogens in India.
