Other claims from this paper (7)
- Observation Mass spectroscopy confirmed the presence of cyclic lipopeptides produced by Bacillus velezensis RC218, with several carbon-length variants in each family.
- Observation Macrolactin, dificidin and bacilysin were also detected as other antimicrobial molecules from B. velezensis RC218.
- Intervention effect In vitro, the lipopeptides significantly reduced mycelial radial growth of three F. graminearum sensu stricto strains by up to 84%.
- Intervention effect In the greenhouse, the pure extract applied before pathogen inoculation reduced Fusarium head blight incidence by 78.5% in the susceptible wheat BioINTA 1005.
- Intervention effect In the greenhouse, the pure extract reduced Fusarium head blight severity by 82.5% in the susceptible wheat BioINTA 1005.
- Intervention effect In the greenhouse, the pure extract reduced Fusarium head blight severity by 66.3% in the tolerant wheat variety Cronox.
- Recommendation The authors conclude that applying the purified lipopeptide extract from B. velezensis RC218 as a preventive against FHB is a promising method to control pathogens.
