Abstract:
The present investigation was carried out with the objectives, identification of causal organism, Effect on germination and vigour. The pathogen was isolated from seeds of onion. The pure culture of pathogen was obtained by single spore isolation method. On the basis of morphological studies, the pathogens were identified as Aspergillus niger, Aspergillus flavus and Fusarium oxysporum f. sp. cepae. Then the effect of Pathogens was studied on basis of germination and vigour index shows the result of lowest germination and vigour index in Aspergillus niger which is followed by Aspergillus flavus and Fusarium oxysporum f. sp. cepae.
