The objective of the study was to evaluate the antifungal activity of aqueous extracts of Brassica nigra, Andrographis paniculata, Targetes erectus and Pinus roxberghaii against Saprolegnia parasitica. Pathogenic fungus Saprolegnia parasitica was isolated from fungal infected specimen of cold water fish Tor putitora. SDA (Sabouroud's Dextrose agar) was used to obtain bacteria free pure culture of the test fungus. Aqueous extracts of leaves of all the test plants prepared at three different concentrations (5%, 8%, 10% w/v) were tested against the mycelial mass of the Saprolegnia parasitica for three different time periods (20 min., 40 min., and 60 min.). Results revealed that all the tested extracts possess high degree of antifungal activities against the test pathogen. Extract of Brassica nigra was found most effective with MIC (minimum inhibitory concentration) of 5% w/v concentration for 20 min. exposure time.
