Abstract: Tuber crops are the third most important food crop for man after cereals and grain legumes. Among them Elephant foot yam (Amorphophallus paeoniifolius), “King of tuber crops”, is important commercial tuber crops of tropical and subtropical region of the world. But Collar rot is one of the important fungal disease (caused by Scerotium rolfsii) reducing the quality and quantity of corms in Amorphophallus. Though chemical measures are recommended based on the previous studies on Sclerotium spp., the new fungicides along with earlier proven fungicides need to be evaluated to find out the superior fungi- toxicants with which the disease can be controlled. Presently, greater emphasis should be placed on biological control of soil borne pathogens in order to reduce the environmental hazards, to avoid the development of resistant strains and to reduce the cost of cultivation. Hence, an integrated approach plays an important role in the effective management of collar rot of the Elephant foot yam caused by Sclerotium rolfsii. In this connection, the literature on various aspects related to the proposed study was collected and summarized in this chapter.
