摘要: The current study aimed at evaluating the possibility of native Bacillus pumilus species to control Fusarium wilt in tomato and examine its effect on plant growth. Biocontrol traits B. strains, biofilm assay, root colonisation vivo studies under pot conditions were determined. Strain ToIrMA-KC806242 formed efficiently could colonise survive rhizosphere (3.1 × 104 CFU/g root). amount auxin production was recorded 29.7 μg/ml 96th hour incubation. Siderophore determined positive, while ToIrMA not able solubilise phosphate compounds or produce cyanide hydrogen. Statistical analysis data revealed that increase shoot length 60 84%, respectively, over control. In addition, about 73% reduction disease incidence experiments. conclusion, this suggests strain as a possible biocontrol agent field
