The toxic effect of 10 fungicides on mycelial growth of Beauveria bassiana (isolate BbCm KKL 1100), a pathogen of rice leaf folders, was evaluated in vitro at three concentrations each: the normal field application rate (I.0X), 10-fold lower rate (0.1X) and 10-fold higher rate (10.0X) on agar plates. The fungicides tested were antagonistic to B. bassiana and inhibited the mycelial growth of either partially or completely depending on the concentration. At 10-fold higher concentration, all 10 fungicides caused total inhibition of mycelial growth. Two fungicides, viz., benomyl and hexaconazole, caused total inhibition of the fungus in all the three concentrations tested. Three fungicides viz., edifenphos, iprobenphos and mancozeb, appeared to be fungistatic at normal field dose (1.0X). Benomyl, carbendazim, hexaconazole, propiconazole and tricyclazole caused total inhibition of mycelial growth at 1.0X, while chlorothalonil, copper oxychloride and edifenphos were comparatively less toxic to B. bassiana causing 63.0, 72.6 and 76.3 per cent mycelial inhibition, respectively at 0.1X.Downloads
