The experiment was conducted under in vitro and field conditions to observe the effect of bio-agents, botanical and fungicides against Alternaria triticina. Eight treatments were taken up with three replications and data collected was analyzed using CRD. Maximum inhibition percent mycelia growth was observed in Propiconazole (89.72%), Hexaconazole (88.44%), Vitavax (87.70%), followed by Trichoderma harzianum (85.50%), Trichoderma viride (83.30%), Pseudomonas fluorescens (80.73%) and neem leaf extract (73.57%) as compared to control (0). An experiment was conducted under field condition to observe the effect of bio-agents, neem leaf extract and fungicides against Alternaria triticina. Eight treatments were taken up with three replications and data collected was analyzed using RBD. Maximum plant height (cm) was observed in T. viride (78.82 cm) followed by T. harzianum (78.27 cm) as compared to control (70.04 cm). T. viride was significantly superior as compared to other treatments. Minimum disease intensity per cent and production of wheat was recorded in treatment Propiconazole @0.1% (18.24% and 37.00 q/ha respectively) followed by Pseudomonas fluorescens @0.5% (20.51% and 30.44 q/ha), as compared to control (43.18% and 20.41 q/ha). Propiconazole was significantly superior as compared to other treatments.
