The laboratory experiments tested the influence of selected pesticides on the symbiotic efficiency and nitrogenase activity of Rhizobium teguminosarum bv. trifolii KGL, Sinorhizobium melilotii Bp and Bradyrhizobium sp. Ornithopus B bacteria entering into symbiosis with clover, lucerne and serradella, respectively. The results obtained indicate that the pesticides used in the experiments (Funaben T...
