Abstract
The experiment was conducted to know the efficacy of different bio control agents at different concentrations against growth of Alternaria alternata, causing leaf blight of Adhatoda zeylanica Medic. Different bio control agents in different solvents were tested in vitro, among all leaves extracts Polyalthiya longifolia was found to be more effective and inhibited cent per cent fungal growth i.e. 100% at 3.0 % concentration in alcoholic form followed by acetone leaves extract at 4.5 % concentration. However, least mycelial growth inhibition was recorded in aqueous leaves extract concentration.

Key words: Adhatoda zeylanica , Alternaria alternate, Biocontrol, Polyalthiya longifolia.
