Abstract:
Banana and plantain constitute a major staple food crop for millions of people in developing countries. Banana plant is one of the most versatile plant that every part of it is useful to cure different types of disorders rhizome rot disease (tip-over) of Banana caused by Pectobacterium carotovorum subsp. carotovorum is found to be a serious disease and cause considerable yield loss. Common cultivars which occupy major proportion viz., Grand Naine, Rasthali and Nendran are extremely prone to this disease. Conducting survey in major cultivating areas helps to identify the intensity of the disease and in turn helps in carrying out suitable management practices. A roving survey was conducted in the year 2020 to assess the incidence of tip over disease of banana in some major banana growing parts of Karnataka viz., Belagavi, Dharwad, Davangere, Haveri, Shimogga and Uttar Kannada districts, reveals that the incidence of rhizome rot/tip-over disease in surveyed areas ranged 5 to 55%. Among the villages surveyed Gokak village of Belgavi district had shown the highest incidence with 55% whereas, least incidence was observed in Shiralkoppa village of Shimogga district. Among taluks surveyed of Gokak taluk of Belgavi district recorded maximum incidence of 42.34% on other hand least incidence of 10.67% was observed in Sagarataluk of shimogga district.
