The colonization and biocontrol effects of plant growth promoting rhizobacteria-Pseudomonads in the rhizosphere of tomatoes were investigated.Pseudomonas CBT1 can colonize the rhizosphere of cucumbers by the methods of seed soaking and root watering.The antimicrobial activity results showed that some isolates suppressed the mycelial growth of B.cinerea and F.oxysporum f.sp. cucumerinum,the highest inhibitory rate was 89.1% and 65.6%,respectively.The efficient isolates were tested and found relative control effects on grey mold and fusarium wilt diseases of cucumber were 44.0%-67.7% and 47.7%-55.4% in pot experiments,respectively.
