Nine rhizobial strains isolated from the root nodules of Cicer arietinum, Vigna radiata, V. mungo, Samania saman, Sesbania sesban, Leucinia sp., Prosopis cineraria and Medicago sativa were used to study their effects on root-infecting fungi viz., Macrophomina phaseolina, Fusarium u solani and Rhizoctonia solani. In dual culture plale assay, strains of Brudyrhizobium sp., and R. meliloti were found to inhibit radial growth of M. phaseolina. F. solani and R. soluni producing zones of inhibition, Brudyrhizobium sp., and R. meliloti either used as seed dressing or as soil drench significantly suppressed root-rot infection caused by M. phaseolina, F. solani and R. solani in okra, a non-leguminous crop under greenhouse conditions. Biomass of plants was also higher in the presence of rhizobia.

Badano działanie dziewięciu linii Rhizobium wyizolowanych z brodawek korzeniowych Cicer arietinum, Vigna radiota, V. mungo, Samaria saman, Sesbania ses ban, Leucinia sp., Prosopis cineraria i Medicago sativa na grzyby infekujące system korzeniowy: Macrophomina phaseolina, Fusarium solani i Rhizoctonia solani, Brudyrhizobium sp. i R. meliloti w badaniach laboratoryjnych hamowały wzrost M. phaseolina, F. solani i R. solani, a użyte do zaprawiania nasion lub doglebowo istotnie ograniczały infekcję korzeni okry powodowaną przez M. phaseolina, F. solani i R. solani w warunkach szklarniowych. Obecność Rhizobium zwiększała produkcję biomasy roślin okry.
