  • Biocontrol agents, Gliocladium virens G872B and Pseudomonas putida Pf3, were compatible each other in colonizing cucumber rhizosphere, which contributed to a long-term inhibition of cucumber Fusarium wilt. G872B colonized successfully on the cucumber root system, irrespective of the introduction of Pf3. Pf3 also colonized well in the cucumber rhizosphere regardless of the presence of G872B. The individual strains effectively suppressed cucumber wilt up to 56 days after transplanting. The combined treatment of G872fB and Pf3 provided a long-term protection of about 80 days with the efficacy greater than that obtained by any individual strains under greenhouse conditions. These results suggest that the colonization of the biological control agents in the rhizosphere could be correlated directly to Fusarium wilt-suppressive potentials.
