Turmeric (Curcuma longa L.) is an important spices crop India is the leading country in respect to area production, export consumption of turmeric in the world. Leaf spot disease of turmeric caused by Colletotrichum capsici is a very serious disease causes huge yield losses in various turmeric growing regions of the world. Hence an experiment was conducted at MES, vegetable science, Anaduat, Kumarganj, Ayodhya to evaluate different fungi toxicants for there efficacy in effective management of the disease under field conditions. The present investigation carried out of nine different fungi toxicants including bioagents and botanicals tested under field conditions, Propiconazole @ 0.1% concentration was found most effective in minimizing the disease intensity with PDI 25.57% and providing the higher yield 343.44 q/ha followed by Hexaconazole with disease intensity (PDI 28.84% and yield 332.89q/ha). Although both the fungi toxicant are statistically at par with each other. The next best fungicides in reducing the disease intensity and enhancing the yield were recorded as (Azoxystrobin) with PDI 35.37% and yield 326.72 q/ha, (Copper oxychloride) with PDI 35.34% and yield 322.94 q/ha, and Kasugamycin with PDI 36.00% and yield 302.22q/ha, above three fungi toxicants were not significantly different with one another. The other remaining fungi toxicants in order of superiority were Trichoderma harzianum with PDI 38.64% and yield 291.17 q/ha, Jeevamruth with PDI 40.96% and yield 283.78q/ha, and NSKE with PDI 43.27% and yield 291.17 q/ha.
