title: Effect of pesticides on growth, respiration and nitrogenase activity ofAzotobacter andAzospirillum.
abstract: Pesticides (Brominal, Cuprosan and Fenvalerate) at 10 and 50 ppm suppressed growth, respiration and nitrogenase activity ofAzotobacter chroococcum, Azospirillum brasilense andAzospirillum lipoferum.
