Summary
Fusarium oxysporum f. sp.dianthi, pathogenic on carnation plants is very sensitive toBacillus subtilis M51 inhibition.Fusarium oxysporum disease (fusariosis) is prevented for a period of two months after treatment of plants withBacillus subtilis M51. The persistence ofB. subtilis M51, marked for selenomycin resistance (MZ51) and inoculated on the roots of carnation cuttings was studied. Soil used was two types: naturally infested withFusarium oxysporum and free from this pathogen. Bacterial cells presence on the roots was detected by direct plating and the presence of the pathogen in the roots was investigated by histological assays. Evidence gathered by these procedures suggest that plant protection is dependent on the physical presence ofB. subtilis M51 cells on the roots.
