Abstract:
Cowpea [Vigna unguiculata (L.)] also known as lobia, chowla, southern pea or black-eyed pea belong to the family leguminaceae. The anthracnose caused by Colletotrichum lindemuthianum is an important fungal disease of cowpea causing economic losses. In present study, biocontrol agents viz., Trichoderma asperellum, T. Harzianum, T. Virens, Aspergillus Niger, Metarrhizium anisopliae, Verticillium lecanii and Paecilomyces lilacinus were tested. Among these highest mycelial growth inhibition over untreated control C. Lindemuthianum was obtained with Trichoderma harzianum (54.44%), followed by T. Asperellum (48.52%). T. Virens (39.25%), Aspergillus Niger (29.63%) Metarrhizium anisoplie (27.41%) and Paecilomyces lilacinus (27.41%), Verticilium licani (25.18%) was found least effective.
