Abstract
Forty nine isolates of endophytic bacteria and three isolates of rhizobacteria were isolated from different sugarcane varieties, clones ofSaccharum spontaneum andErianthus sp. All the bacterial isolates were evaluated for antagonism against the red rot pathogen of sugarcaneColletotrichum falcatum. The results showed that seven isolates were effective in inhibiting fungal mycelial growth underin vitro conditions. A major proportion of endophytic and rhizosphere isolates belonged to gram-positive rods. Biochemical characterization of the seven efficient antagonistic isolates revealed that three isolates viz., 687-2bl, 71-1-1a and 46-la2 belonged toPseudomonas aeruginosa, three isolates viz. SS1, SS2 and SS3 belonged toPseudomonas fluorescens and one isolate viz. 312-2b, wasPseudomonas putida.
