     Plant growth promoting bacteria are capable of fixing atmospheric nitrogen, solubilizing phosphorus, iron and producing plant hormons viz., auxins, gibberellins and cytokinins and promote plant growth by directly affecting the metabolism of the plants by providing substances that are usually in short supply.  Additionally they improve plant tolerance to drought high salinity and metal toxicity through the production of enzymes-amino cyclopropane carbonylate deaminase.  PGPB prevents the deleterious effects of phytopathogenic microorganisms.  They produce antibiotics that harm or inhibit other microbes, but not plants, by limiting the availability of iron to pathogens or by altering the metabolism of the host plant to increase its resistance to pathogen infection.  In the present study forty pseudomonas isolates were screened for their biocontrol ability against F. oxysporum and R.solani.  The isolate of TMPs-19 recorded a maximum antifungal activity against F.oxysporum and R.solani (23.55 in mm and 20.44 in mm) followed by TMPs-32, TMPs-35 and TMPs-1.  The minimum antifungal activity F.oxysporum and R.solani noted with the isolate TMPS-41 (5.40 in mm and 5.18 in mm).
