Abstract:
Due to storage rot, heavy losses occurring in tubers. Considering heavy losses and regular incidence of the disease of in elephant foot yam, lesser yam and greater yam in recent years, created interest to conduct this research study. This review presents different diseases associated with yam and the management strategies. Sclerotium rolfsii, Aspergillus flavus and Rhizopus stolonifer were isolated from rotten tubers of elephant foot yam, Fusarium solani was isolated from rotten tubers of lesser yam and Rhizopus stolonifer was isolated from rotten tubers of greater yam. Pathogenicity test revealed that all the isolated fungus were pathogenic on tuber crops. In storage, four different fungicides (12% WP + mancozeb 63% WP, mancozeb 75% WP, carbendazim 50% WP and captan 50% WP), organic (cow dung slurry) and bio-agent (T. harzianum) were evaluated against storage rot of tuber crops. In all tuber crops, T₄- SNRE (20%) + carbendazim 12% WP + mancozeb 63% WP (0.2%) was most effective treatment and showed less weight loss percentage, less rotting percentage and more sprouting percentage at 120 days of storage. In elephant foot yam, this treatment showed 36.00% weight loss, 13.33% rotting and 86.67% sprouting at 120 days of storage. Also, in lesser yam, this treatment showed less weight loss percent (34.20%), less rotting percent (17.78%) and more sprouting percent (82.2%). Similarly, in greater yam, treatment T₄ showed 23.15% weight loss, 13.33% rotting and 88.89% sprouting at 120 days of storage.
