Abstract
About 35 to 40 per cent onion is lost due to
damage caused by storage diseases among which fungal bulb rot imparts 15 to 30
per cent losses during storage of different varieties. Post harvest diseases deteriorate the quality and quantity of the onion
crop. Among which black mold, basal rot, green mold, blue mold and anthracnose
are primary concern. An intensive roving survey was carried out in vegetable
and APMC market of Kalyana Karnataka region during 2024-25 viz., Bidar, Kalaburagi, Raichur, Yadgir, Vijayanagara, Koppal and Ballari.
In each taluk50 bulbs from 3to 4 lots were selected to assess the infection and
frequency of the diseases. The highest mean percent disease infection was
recorded in Yadgir district (42.07%). The highest mean per cent frequency
of Aspergillus niger was observed in Ballari district (73.33%)
and the highest per cent frequency of Penicillium spp. was
noticed in Koppal district (38.46%). Maximum per cent frequency of Fusarium spp. was recorded in Vijayanagara
district (28.50%). Highest per cent frequency of Aspergillus flavus was
found in Bidar district (23.00%). Colletotrichum spp. was
