An experiment was carried out to evaluate the efficacy of fungicides (Calcium chloride, Mancozeb, Carbendazim), bio-agents (Trichoderma harzianum, T. viride and Pseudomonas fluorescens) against root rot of fennel (Fusarium oxysporum). All the treatments found effective against Fusarium oxysporum. Maximum inhibition per cent was recorded on Carbendazim (T1-99.44%) which was statistically superior on Mancozeb (T3- 98.77%) and T3 statistically superior on Calcium chloride (T2-81.33% ) which was statistically at par with T. harzianum (T5-79.44%) followed by Trichoderma viride (T4- 76.88%) Pseudomonas fluorescens (T6- 72.66%) while the minimum in control (T0-51.00%) under in vitro conditions. The experiment was laid out in RBD with six treatments and three replications for in vivo studies. Among all the treatments the minimum disease incidence (%) of root rot was recorded in T1 - carbendazim (13.50%), followed by T3-mancozeb (15.00%), T2-Calcium chloride (18.65%), T5-Trichoderma harzianum (21.00%) T4-Trichoderma viride (21.65%), T6-Pseudomonas fluorescence (25.27%). In the present investigation carbendazim showed least disease incidence of 13.50% followed by mancozeb, calcium chloride, Trichoderma harzianum which showed 15.00, 18.65 and 21.00% disease incidence, respectively.
