Description: The potential of Pseudomonas spp. as biocontrol agent against potato cyst nematode Globodera rostochiensis was tested in pot experiment under glasshouse conditions. The best control of nematode population was provided by the bacterial strains Pseudomonas putida 3 (2) and Pseudomonas aurantiacea 13 (2). The plant growing parameters in the treatments enhanced as compared with the inoculated with Globodera rostochiensis. The two bacterial strains significantly reduced nematode populations by 40.7 PROCENT - 42.2 PROCENT compared to the control
