The great importance of red clover is the fact that it lives in symbiosis with Rhizobium leguminosarum bv. trifoli. In addition to promoting plant growth, productivity and biomass, the bacteria also have an important role in disease control. Apart from useful microorganisms, many soil pathogenic microorganisms inhabit red clover roots and under favorable conditions they cause infections and diseases of the cultivated plants. On the infected red clover plants Fusarium spp. can cause several symptoms: vascular wilt on older plants, dumping of seedlings, root rot, rot of root base and crown rot. In the present study, the antagonistic potential was evaluated for two bacteria isolates preliminarily determined as R. leguminosarum bv. trifoli (CD1 and CD6) against three isolates Fusarium spp. (G1, G2 and G3) who were obtained from the roots of symptomatic red clover plants. The research was performed in in vitro agar plate (PDA medium) by methods of dual culture (“bacterial ring”). The comparison of growth assessment of fungi after they were grown together with rhizobia in a single plate and growth of fungi in individual plates was performed. Both rhizobia isolates showed significant antifungal activity against all the tested phytopathogenic fungi. Growth inhibition of G1, G2 and G3 was evaluated (%) using both rhizobia isolates, CD1 varied from 30 to 43 % and CD6 from 14 to 32 %.enRhizobiaFusariumRed cloverANTIFUNGAL ACTIVITY OF RHIZOBIA AGAINST RED CLOVER PATHOGENS FROM GENUS FUSARIUMconferenceObject
