Herbicides effects on symbiotic nitrogen-fixing bacteria

Rhizobia are an important component of sustainable agricultural production. In symbiosis with legumes, they provide adequate amounts nitrogen for their growth and leave in the soil crops that follow rotation. One major threats to symbiotic fixation herbicides. The effect herbicides on can be positive or negative. is manifested stimulation development rhizobia. When negatively affected, efficiency reduced, resulting lower legume yield. Herbicides contact rhizobia immediately after application or, case persistent herbicides, later growing season. may affect rhizobia, host plant, establishment symbiosis.
