Abstract
Ten bacterial strains, selected from a bulk of isolates recovered from tomatorhizosphere, were tested for their ability to induce systemic resistance or bio-controlagents against Meloidogyne incognita in tomato under greenhouse condition.Results showed that all ten tested bacterial strains showed significant reduction innematode development and reproduction. The most effective strains wereMethylomonas methanica, Bacillus cereus, Bacillus brevis and Obesumbacterium proteus. They were achieving the highest reduction in nematode total populationand fecundity. Plant growth was improved as a result of application of rhizobacteria.Antioxidant enzymes activity for both peroxidase and polyphenol oxidase wereelevated in bacteriazied plants compared nematode infected plant as well as totalphenol content. Results revealed that crude culture suspension of bacteria wasmore effective for reducing nematode population followed by cell-free culturefiltrates, bacterial live cells and bacterial dead cells suspension, sequentially. It wasconcluded that these bacteria able to suppress M. incognita as resistance inducersfor tomato plants or bio-control agents.
