Utilization of Medicinal Plants to Control Seed Borne Pathogens of Selected Seeds

Abstract

The aqueous, alcoholic, and ethyl acetate extracts of the bark of five Terminalia species (T. alata, T. arjuna, T. bellerica, T. catappa, and T. chebula) were tested against five plant pathogenic fungi: Aspergillus flavus, Aspergillus niger, Alternaria brassicicola, Alternaria alternata, and Helminthosporium tetramera. The antifungal activities of all these extracts were determined by the paper disc method. Nearly all the extracts were found effective against these fungi. The positive results obtained were compared with those of the reference standard fungicide, carbendazim. It was found that most of the extracts were more effective against the fungi than the control fungicide.
