Alternaria blight caused Alternaria brassicae (Berk.) Sacc. is a serious disease of Indian mustard through out thecountry. Extracts of 54 plants wastestedagainst their efficacyat 5% and 10% concentration (in-vitro). All the botanicals tested were effective showingdifferent levels of toxicity against Alternaria brassicae in inhibitingthe growth of pathogen significantly over control but the degree of inhibition varied from 0.00 (check)to 60.61 per cent (Garlic)at 5 per cent and 0.00 (check) to 72.21(Garlic)at 10 per cent concentration.In this way the maximum inhibition was recorded through Garlic extracts at both the concentration tested fallowed by Eucalyptus.There was no any fungitoxicantic character in foundbetter for the inhibitory effectagainst Aloevera the pathogens. All the 29 botanicals test extracts inhibited the spore germination ofthe pathogens. Garlic and Eucalyptus was most fungi toxic causing 100% inhibition at 5% and 10% concentration followed by Ashok (90.77% and 100%), Tulsi (87.44% and 100%), Datura (85.09% and 100%), Neem (82.44% and 100%), respectively.
