Growth profiles of nematode trapping fungi Arthrobotrys oligospora and Duddingtonia jlagrans were measured in corn meal agar plates in presence of different concentrations of heavy metals and a fungicide, carbendazim. No significant effect on growth profiles of the fungi was observed at 100–1000 μM concentrations of sodium arsenate and lead nitrate. While D. flagrans displayed total resistance to mercuric chloride, significant inhibitions of growth (P <0.05) were observed for A. oligospora at concentrations of 500 and 1000 μM. At carbendazim concentrations of 2.5 to 4.5 ppm, significant growth inhibitions of both the fungi were recorded. The influence was so pronounced for D. flagrans that the fungus could not grow in presence of 4.5 ppm concentration of carbendazim. Significance of these observations is discussed.
