Study on post-harvest diseases of rabi vegetables in Jorhat district of Assam, India

Abstract

A preliminary study was undertaken to screen the post-harvest diseases associated with some common rabi vegetables in the Jorhat districts of Assam, India. The infected vegetables were collected from a few local markets (Rajoi tiniali market, Unnayan market, Chowk Bazar sabji market) of Jorhat District of Assam. Isolation, purification, identification, and maintenance of the pathogenic isolates were carried out following standard protocol. The isolated fungal and bacterial pathogens were identified based on cultural and morphological characters. Pathogenicity tests of the isolated pathogens in different vegeatables confirmed association of Alternaria sp. in tomato, Cladosporium sp. in cauliflower, Erwinia sp. in capsicum, Geotrichum sp. in carrot, Sclerotinia sp. in pea and bean) and Phomopsis sp. in brinjal.
