Studies on fungi associated with storage rot of Sweet potato [Ipomoea batatas (L.) Lam.] root tubers in Odisha, India
Abstract
An extensive survey was conducted in order to assess the fungi associated with post-harvest decay of sweet potato root tubers in different market places of Odisha, India, during 2014-15. Rotten sweet potato samples were collected from six different market places such as Bhubaneswar, Cuttack, Jajpur, Puri, Balasore and Bhadrak. The five fungal species namely Aspergillus flavus, Aspergillus niger, Fusarium oxysporum, Geotrichum candidum and Rhizopus oryzae were isolated from the rotten samples. Of these, Rhizopus oryzae showed the highest percentage of frequency of occurrence followed by Fusarium oxysporum, Aspergillus niger, Aspergillus flavus while Geotrichum candidum had the least percentage of frequency. Pathogenicity tests revealed that all the isolated fungi were pathogenic to sweet potato root tubers. However, Rhizopus oryzae was found to be most pathogenic leading to rapid disintegration of the infected tubers within 15 days of inoculation, while Geotrichum candidum was the least pathogenic. The study on the effect of three solid nutrient media on growth of these test fungi revealed that Sabouraud Dextrose Agar supported highest growth followed by Czapek Dox Agar and Potato Dextrose Agar. The use of improved sweet potato varieties, good storage facilities and adequate control measures need to be encouraged in order to reduce storage rot of sweet potato root tubers in Odisha
