Root rot disease in Medicinal Coleus is serious problem in all medicinal coleus growing parts of Tamil Nadu. Hence attempts were made to manage the disease through Integrated Disease Management modules. The field experimental results showed that the module I comprising Field sanitation + Soil application of Zinc sulphate (20kg/ha) + Dipping stem cuttings in Pseudomonas fluorescens (20g/lit of water) + Drench with (Pseudomonas fluorescens + Trichoderma viride + FYM + Neem cake (112020). The mixture applied in the soil @ 100g/plant on 30 DAP + Drenching P. fluorescens (0.1%) on 40 DAP repeat the drench 4 times at an interval of 15 days recorded the minimum root rot disease incidence 12.2 and 27.7 per cent on 45 and 90 DAP and recorded the highest tuber yield 5161 kg/ ha-1compared to other modules with the CB ratio of 14.5 compared to control with root rot disease 33.0 and 80.0 per cent on 45 and 90 DAP and the lowest tuber yield of 899.7 kg/ ha-1.
