To study the effect of different fungicides against Alternaria leaf spot of ber, fungus was isolated from the infected leaves of ber plant and cultural and morphological study was done through Poison Food Technique to find that the fungus was Alternaria alternata having branched and septate mycelium with light brown to blackish conidiophores in acropetal chain and the conidia having olive green to dark brown colour with transverse and longitudinal septa. The evaluation of the fungal growth was done with chemical fungicides. A total of nine fungicides were tested at 100, 250, 500, 1000, 1500, 2000 and 2500 ppm concentrations, out of which Hexaconazole 5% EC (97.95%) showed maximum mycelium growth inhibition followed by Tebuconazole 25% EC (96.57%) and Tebuconazole 25% + Trifloxystrobin 25% WG (95.27%) while minimum inhibition was by Propineb 70% WP (78.41%) followed by Carbendazim 50% WP (79.17%). The fungicides tested in present study have also shown potential in controlling A. alternate leaf spot disease of Ber.
