Abstract
Bacterial strains Bacillus brevis , B. cereus , B. firmus , Klebsiella planticola , Lactobacillus agilis , L. fermentum , Methylomonas methanica , Neisseria elongata , Obesumbacterium proteus and Pseudomonas aeruginosa recovered from tomato rhizosphere and tested for their abilit y to induce systemic resistance or bio-control agen t against Meloidogyne incognita in tomato under greenhouse condition. Results showed that all tested bacterial strains showed significant reduction in nematode development and reproduction. The most effective strains were M. methanica , B. cereus , B. brevis and O. proteus . They were achieving the highest reduction in nema tode total population and fecundity. Plant growth was improved as a result of application of rhizobacteria. Antio xidant enzymes activity for both peroxidase and polyphenol oxidase were elevated in bacteriazied plants as co mpared nematode infected plant as well as total phenol con tent. Results revealed that crude culture suspensio n of bacteria was more effective for reducing nematode population followed by cell-free culture filtrates, bacterial live cells and bacterial dead cells, sequentially. It was conclude d that bacteria has induced tomato resistance or bi o-control effects against M. incognita in tomato.
