Turmeric growers in Odisha have challenges to manage the loss in yield from 40 to 60 per cent due to leaf spot disease. To increase productivity, bio-agents and chemicals are tested in the field to minimize the incidence of disease. An experiment became conducted to evaluate the efficacy of bio-agents and fungicides viz., seed remedy with T. viride@5gkg-1 of seed & P. fluorescens @10gkg-1 of seed, soil utility of 4kg bio-agents of T. viride & P. fluorescens in 10 qtls of FYM incubated in 30% moisture for 15 days under shed and bio-agents of T. viride & P. flurescens in 10qts of FYM incubated in 30% moisture for 15 days below shed and applying during earthing up, seed treatment with T. viride @5gkg-1 of seed & P. fluorescens@ 10gkg-1 of seed + soil applications of 4kg bio-agents of T. viride & P. flurescens in 10qts of FYM incubated in 30% moisture for 15 days under shed and applying throughout earthing up, Seed remedy with Propiconazole @0.1% + Foliar spray of Propiconazole (0.1%) at 45 & 60DAP for the control of leaf spot disease of turmeric (Curcuma longa) in the nearby research generation transfer Station, G. Udayagiri, Kandhamal, Odisha university of Agriculture and era, Bhubaneswar. Percent disease intensity has been substantially reduced from 42.22 (untreated control) to 14.00 in seed treatment with T. viride @5gkg-1 of seed & P. fluorescens @10gkg-1 of seed + soil application of 4kg bio-agents of T. viride & P. flurescens in 10qtls of FYM incubated in neem cake -cow dung combination @ 1.5qha-1 incubated in 30% moisture for 5 days underneath shed and making use of in the course of earthing up, seed application with T. viride @5gkg-1 of seed & P. fluorescens @10gkg-1 of seed + soil application of 4kg bio-agents of T. viride & P. flurescens in 10qts of FYM incubated in 30% moisture for 15 days under shed and applying throughout earthing up determined to be best treatments with highest yield 14.82 (tha-1) followed by seed treatment with Propiconazole @0.1% + Foliar spray of Propiconazole (0.1%) at 45 & 60DAP with 14.11 tha-1 yield and 16.41 % disease intensity.

Seed treatment with T. viride @5gkg-1 of seed & P. fluorescens @10gkg-1 of seed+ soil application of 4kg bio-agents of T. viride & P. flurescens in in incubated neem cake -cowdung mixture @ 1.5qha-1 incubated in 30% moisture for 5days under shed and apply during earthing up can able to manage the disease upto 64 %.Farmers field research and MLTs are to continued for further research.
