    Abstract
    Biocontrol of potato cyst nematode Globodera rostochiensis was studied on potato using three isolates of rhizobacter from Banjarnegara (Pseudomonas diminuta, Bacillus alvei, Bacillus stearothermophilus). In a greenhouse experiment, all three isolates of rhizobacter not affect plant height, root and tuber weight but significantly increased root length and significantly reduced the number of cyst formed. Rhizobacter isolates were tested for siderophores, cytokinin and giberellic acid production. All three isolates of rhizobacter produced cytokinin and giberellic acid but didn’t produce siderophores on Chrome-Azurol Sulphonate (CAS). This study suggests that Pseudomonas diminuta, Bacillus alvei, and Bacillus stearothermophilus may be used for the biocontrol of G. rostochiensis on potato. Mode of action of this isolates through cytokinin and giberellic acid production.
