Recently, it has been observed in the authors' laboratory that growth, nitrogen fixation, protein content of cyanobacteria Nostoc muscorum were reduced by methylparathion and benthiocarb treatment. Though many works on toxicity of pesticides on cyanobacteria, specially on growth, photosynthesis and nitrogen fixation are available, the effects of pesticides on antioxidant enzyme levels is still unclear. In this communication, studies have been presented on the effects of organophosphate insecticide methyl-parathione and carbamate herbicide benthiocarb, on glutathione content, glutathione reductase (GR) and superoxide dismutase (SOD) activities of filamentous, nitrogen-fixing cyanobacteria Nostoc muscorum.
