Abstract:
Onion is one of the important bulbous crops that is commercially grown in India and all throughout the world. It is an indispensable part of every kitchen in Indian households and is valued for its pungency and flavors. As onion export contribute immensely to foreign exchange earnings, the production of healthy onion bulbs amenable to the export market should be a major objective. Bacterial soft rot in onion is a devastating disease as it reduces the quantity and quality of onions, thus reducing their marketability value. A roving survey in four districts of Northern Karnataka during two consecutive years revealed higher incidence of soft rot in onion in Bagalkot (31.12%) and Dharwad (36.06%) districts in 2021 and 2022 respectively. The bacteria associated with soft rot symptoms was isolated and the pathogenicity was proved.
