Abstracts |
The use of antagonistic microorganism for the biological control of root disease is becoming an important alternative or supplement to chemical pesticides. In the present study, we investigated the potential of beneficial rhizobacteria to interact synergistically with indigenous arbuscular mycorrhiza fungi (AMF), furthermore for improvement plant growth of two tomato varieties using replant disease. Soil inoculation with Pseudomonas sp. "ProradixR" and Bacillus amyloliquefaciens FZB42 significantly improved the root and shoot biomass production of the two tomato varieties growing on pathogen-infected soil. Roots of both tomato varieties were not only healthier but also showed a significantly higher colonization by AMF. Root lesions was significantly lower in the rhizosphere soils of both tomato varieties when inoculated with P. sp. "ProradixReg." or B. amyloliquefaciens FZB42 compared to the untreated control. The concentration of macro and micronutrients in tomato shoots was higher in the P. sp. "ProradixReg." and B. amyloliquefaciens FZB42 treated plants when compared to the untreated control. The result obtained suggest an important role of rhizosphere interactions for the expression of bio-control mechanisms by inoculation with effective Pseudomonas and Bacillus strains independent of simple antagonistic effects.
