Turmeric (Curcuma longa L.) known as golden spice as well as “spice of life” has emerged as low volume high value crop. Among various diseases attacking turmeric, leaf blotch disease caused by Taphrina maculans and leaf spot disease caused by Colletotrichum capsici are two most serious foliar disease. Turmeric yield losses have been recorded up to 37.6-52.9 per cent and upto 50 per cent in leaf blotch and spot disease respectively. Considering the seriousness of these diseases, present investigation was carried out on management of leaf blotch and leaf spot diseases of turmeric by fungicides and bio-control agents at Tirhut College of Agriculture, Dholi, Muzaffarpur (Bihar) during 2015-16 to 2017-18. Under disease management, Lowest disease viz., Colletotrichum leaf spot (PDI=6.67) and Taphrina leaf spot (PDI=13.34) were recorded in treatment where pre-planting treatment of rhizome and spraying of crop at 90, 105 and 120 DAP was done with Propiconazole (25 EC) @0.1% and Zineb (75 WP) @0.1% respectively over control (PDI=43.89 & 47.22 respectively). Best treatment with respect to recording of highest yield of 38.09t/ha over control (25.77t/ha) and highest ICBR (1:22.22) were recorded in treatment where pre-planting treatment of rhizome and spraying of crop at 90, 105 and 120 DAP was done with Propiconazole (25 EC) @0.1% and Zineb (75 WP) @0.1% respectively.
