Abstract: An integrated control will have to be considered with bio-agents, botanicals as well as chemicals for the management of airborne pathogens. Integrated disease management is a good strategy for the control of the early blight disease in tomato. Therefore, keeping in view of above facts present experiments were conduct on “Development of integrated management strategies for the control of Early Blight in tomato”. Results indicate that the most effective treatment was found T5 = Propineb @ 3 g /kg (ST) + Trifloxystrobin 25% + tebuconazole 50% WG @ 0. 05% (FS) + NSKE @ 5% (FS) which exhibited minimum diseases intensity, AUDPC and maximum number of fruits and fruit yield followed by T₆ = Propineb @ 3 g /kg (ST) + Azoxystrobin 23% SC @ 0.1% + NSKE @ 5% (FS)). While, treatment T₇ = Propineb @ 3 g /kg (ST) + NSKE @ 5% (FS) + Pseudomonas florescence @ 1x 10⁹) was observed less effective against early blight. Highest return was obtained from treatment T₅ followed by T₆. However, highest C: B ratio (1:67.24) was obtained in the treatment T₂ = Propineb @ 3 g /kg (ST) + Trifloxystrobin 25% + tebuconazole 50% WG @ 0. 05% (FS) followed by T₅ = Propineb @ 3 g /kg (ST) + Trifloxystrobin 25% + tebuconazole 50% WG @ 0. 05% (FS) + NSKE @ 5% (FS) (1:60.36). While, lowest C: B ratio was obtained (1:20.13) in treatment T₁ = Propineb @ 3 g /kg (ST) + Azoxystrobin 23% SC @ 0.1% (FS).
