India is the major producer of the banana crop in the world. Banana is divided into two types.First one is desert type and the second one is the cooking type of banana. Cooking banana is thestapple food in many parts of the India especially in Kerala. Major problem in cooking variety isthat these varieties are highly susceptible to rhizome rot disease. To control this integration ofphysical method (collection and destruction) and chemical method (application of fungicide andbactericide) was used at an interval of 7 days and 14 days. The results showed that combinationof physical method and application of MetalaxylMz (4 mgL-1) + streptomycin (1.5 mg/10L) at 7days interval had resulted in survival percentage (96.03%), average number of the fingers/hand(12.67), average number of the hands/bunch (9.27), average weight of the bunch (29.67 kg) andyield per hectare (61.58 t/ha) in first crop. on the other hand, ratoon crop had recorded maximumsurvival percentage (99.83%), maximum average number of the fingers/hand (13.00), maximumaverage number of the hands/bunch (8.53), maximum average weight of the bunch (28.41kg) andmaximum yield per hectare (59.45t/ha). This experiment concluded that rhizome rot can becompletely control by the integrated physical and chemical method of disease management.
