The study was carried out to evaluate the efficacy of fungicides and bio-agents against the leaf and neck blast disease in paddy during Kharif season of 2013-14. Among the evaluated fungicides and bio-agents, Tricyclazole 75% WP was effectively manage the incidence of leaf and neck blast (16.3 and 21.22 %, respectively) and found most economical fungicide among all treatments with highest yield (35.61q/ha) and B: C ratio (1: 2.03), maximum reduction of leaf and neck blast (66.61 and 43.15 %, respectively) followed by Tebuconazole 25.9% EC and combination of Tebuconazole 50% EC + Trifloxystrobin 25% WG. All these three fungicides were found quite effective against the leaf and neck blast of paddy. Bio-agents were less effective as compared to fungicides. In the field demonstration, Tricyclazole 75% WP reduced the incidence upto 78.13% and recorded 17.56 q/ha technology gap, 11.52 q/ha extension gap and technology index was calculated as 29.25%.
