Abstract

Effect of various diseases management tools were tested as a part of suitable option for management of foliar diseases of Turmeric. Five fungicides viz., Propiconazole (0.1%), mancozeb (0.25%), carbendazim (0.1%), hexaconazole (0.1%), penconazole (0.1%) with three botanicals viz., Azadirchta indica seed extract(5%), Ageal marmalas leaf extract (5%) and Eucalypyus leaf extract (5%) against foliar diseases of turmeric. All fungicides and botanicals were found significantaly superior over check. Amongst fungicides propiconazole (91.98%), hexaconazole (87.55%); penconazole (85.62%) and carbendazim (84.02%) were effective to inhibit the growth of Colletotrkhum dematium (91.98–84.02%). Significant inhibition was recorded in propiconazole (91.98%) as against control (80.33mm), Azadirchta indica seed extract was effective among botanicals to check the mycelial growth of C. dematium (74.69%) as compared to control. Whereas, propiconazole was effective against C. dematium (11.68%) and Taphrina rnaculans (12.34%) with added benefit of rhizome yield. This fungicide was found best against foliar diseases under field conditions. Amongst botanicals Azadirehta indica seed extract (41.58% and 32.08%) and Eucalyptus leaf extract (49.03% and 32.08%) were found effective to check these two leaf spot diseases of Turmeric.
