Abstract
A survey of fungi associated with post-harvest deterioration of
places of Odisha, India, in 2014-15. Rotten
Jajpur, Puri, Balasore and Bhadrak. The fungal species such as; Aspergillus flavus and
rotten bulbs of onion; Aspergillus niger, Penicillium sp. and
these, Aspergillus niger has highest percentage frequency of occurrence in onion while in garlic the frequen
sp. was more. The percentage of their frequency is 50.3 % and 86.16 % respectively. The result of Pathogenicity test
indicated that all the isolated fungi were pathogenic to their respective host and it was found that
Penicillium sp. were more pathogenic to onion and garlic respectively than that of other isolated fungi. They cause 69 % and
74 % of rotting of onion and garlic respectively. In order to reduce storage rot of
encourage the use of improved varieties, good storage facilities and adequate control measures.

Introduction
For India, onion is one of the potential foreign exchange earners
as it stood second largest producer of onions after China,
producing 1.6 million MT annually1. Since long g
known as a valuable spice for foods and a popular remedy for
various ailments and physiological disorder all over the World.
It is used for the preparation of chutney, pickles, curry powder,
curried vegetables, meat and tomato ketchup.
During storage bulb rots cause huge onion loss. Raju and Naik
elaborated that onion suffers from many post
diseases, like the soft rot, brown rot and smudge
such as Fusarium sp. Botrytis spp. and Aspergilus niger
found on diseased onion bulbs during storage conditions
Storage decay resulted in the reduction in the quantity and
quality of onion that affects the market value
consequence may be mycotoxin contamination of the affected
material5. Post-harvest rotting of fruits and vegetables during
the supply chain has been identified as the greatest cause of
post-harvest losses, which results in significant economic losses 6. Various fungi were reported to be associated with storage rots
of garlic such as Alternaria alternarta, Aspergillus repens
