Pigeonpea wilt disease caused by Fusarium oxysporum f. sp. udum is one of most devasting seedborne disease. In this experiment total eight seed dressing fungicides at their recommended dosages were evaluated in-vitro by poisoned food technique, against Fusarium oxysporum f. sp. udum causing wilt. The systemic fungicides viz. Carbendazim 50% WP, thiophanate methyl 70% WP, tebuconazole 25% WG, pyroclostrobin 20% WG and combi fungicides viz. corboxin 37.5% + thiram 37.5% WP, carbendazim 12% + mancozeb 63% 75 WP and contact fungicides captan 75% WP were evaluated. However, the fungicides viz., tebuconazole 25% WG, carboxin 37.5% + thiram 37.5% 75 WP and carbendazim 12% + mancozeb 63% 75 WP were found most effective with 100 per cent mycelial growth inhibition of Fusariumoxysporumf. sp. udum. The eight bioagents evaluated by dual culture technique, among that most effective bioagent was Trichoderma harzianum, which resulted in significantly highest mycelial growth inhibition (85.62%), followed by T. hamatum (82.61%). T. asperellum, Aspergillus niger, T. koningii, T. longibrachitum which also caused mycelial growth inhibition in the range of 61.64 to 77.32 per cent.
