BİOLOGİCAL CONTROL OF Rhizoctonia solani KÜHN. WİTH RHİZOBACTERİA ISOLATED FROM DİFFERENT SOİL AND Calligonum polygonoides L. subsp. comosum (L’HÉR.)

In this study, the biological control activities of bacteria strains, which have been isolated from volcanic, sandy, salty soils and Ebu Cehil plant Calligonum polygonoides L. subsp. comosum (L’Hér.) were investigated against isolates Rhizoctonia solani causing root rot in beans. As result isolation, 83 strains obtained identified by biochemical tests fatty acid methyl esterase analyses. vitro conditions, 20 among found to be effective it was determined that these inhibited mycelial growth forming a prevention zone ranging between 0.1 cm 2.4 cm. The rate pathogen range 50%-66% maximum. vivo successfully inhibit disease development compared group. Bacillus thuringiensis israelensis HV43, subtilis HV34, cereus GC subgroup A HT21 HT30 prevent incidence with an effectiveness 100%.
