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. Among the districts Belgavi recorded maximum incidence with 35.22% and least incidence of 9.67% was observed in Shimogga district. Incidence of disease is high in black soils with 55% compared to red soils in which maximum incidence recorded was 33%.

It was known from the time immemorial as cheapest, plentiful and most nourishing of all the fruits. Banana is generally grown throughout the country all-round the year and grows much better in warm humid climates. Banana have been called the world’s most perfect fruits, as they are high in potassium, low in fat and good source of vitamins and fiber. 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. Banana is delicious and usually seedless and is available in all seasons and it is very hygienic and nutritious. Banana is a staple starch for many tropical populations. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet and texture from firm to mushy. Both skin and inner part can be eaten raw or cooked. Banana belongs to family Musaceae of order Scitaminae. The center of origin of this tropical fruit has been considered to be the Malayan archipelago also called as Garden of Paradise. Banana contains nearly all the essential nutrients including minerals, vitamins and has several medicinal properties. It is a rich source of energy and each banana weighing around 100 g would provide the energy requirement (2,400 cal/day) of a sedentary man. It contains 27 per cent carbohydrates, 70 per cent moisture, little amount of proteins and fat. The best known bananas of commercial type all over the world belong to the pure Musaacuminata AAA group. In India, banana growing states are Karnataka, Kerala, Maharashtra and Tamil Nadu. In India, area under Banana cultivation is 8.58 lakh ha with a production of 29.16 mT during 2016-17. In Karnataka, area under cultivation is 1.01 lakh ha with a production of 2.49 mT (Anon., 2017).
