<br/><br/> The present study was search about the relationship between root-knot nematode and Ralstonia solanacearum on potato (Lady rosseta c.v) and the biological control of them by two plant growth promoting rhizobacteria i.e (Serratia marcescens and Pseudomonas fluorescens ), blue green algae (Nostoc muscurum) and compost in a split root system. Results revealed that potato cv. lady rosseta was highly susceptible to bacterial wilt disease and the combinations of M. incognita and R. solanacearum recorded higher bacterial wilt disease rating than those inoculated with both pathogens individually. All bio-control agents significantly increased Percentage of disease reduction with R.solanacearum and M.incognita (alone or combined) specially blue green algae (Nostoc muscurum) and compost by (96-84%), (80-86 %) respectively, reduced significantly all nematode parameters i.e. number of galls /half root system, number of egg masses /half root system and number of juveniles/250g soil when compared to plants treated with nematode alone.
