Four experiments were conducted at Gazipur, Madhupur, Bogra and Khagrachari to develop the appropriate management package for rhizome rot in replicated manner following randomized complete block design with 11 treatments having plant materials, chemicals and poultry bedding during 2014-15 cropping season. The germination was found 53 to 97 % at Bogra whereas it was higher (84-97 %) at Gazipur and Madhupur field at Tangail (88-96 %). The germination ranged from 59-83 % in Khagrachari. The disease incidence was the lowest (5.98 %) using seed treatment with Ridomil gold (0.2%) and its 2 times soil drenching followed by seed treatment with Chlorox (10 %) in all locations. The highest disease incidence (64.94 %) was recorded in the control plots of all locations. The highest yield 22.92 t/ha was obtained in seed treatment with Chlorox (10 %) followed by seed treatment using Ridomil and its 2 times soil drenching (18.11 t/ha) at Gazipur. All treatments gave higher yield compared to control irrespective of locations.
