This study was designed to evaluate the influence of five seed-protectant pesticide (fluxapiroxad, triticonazol, tetraconazol + tiofant metil, difenoconazol + fludioxonil and teflutrin + fludioxonil) at recommended concentration (for wheat seed treatment) on the numerical concentration in soil of Azotobacter spp. and Clostridium spp. nitrogen-fixing bacteria. The control variant was represend by soil sample where no seed treatment was applied. Soil samples were taken periodically and analyzed for the numerical determination of nitrogen-fixing bacteria of the genera Azotobacter and Clostridium.
