Title

Biocontrol Efficacy and Mechanisms of Bacillus velezensis AP6 Against Brown Rot in Yam by Fusarium solani

Yangtian Li; Bowen Tang; Jinchi Xie; et al. Journal of Fungi 2026. doi:10.3390/jof12050345

Other claims from this paper (10)

Intervention effect Strain AP6 strongly antagonised F. solani, with an inhibition rate of 60.2%.
Observation Strain AP6 showed broad-spectrum antagonistic activity.
Observation Strain AP6 can produce siderophores, amylase and protease.
Observation Strain AP6 can produce cellulase and form biofilms.
Observation Strain AP6 changed the hyphal morphology of F. solani, inhibited spore germination and reduced pathogen viability.
Intervention effect Strain AP6 alleviated the disease severity of yam.
Intervention effect Strain AP6 induced accumulation of reactive oxygen species in yam.
Mechanism The authors interpret the reactive oxygen species accumulation as enhancing the defense responses of yam.
Intervention effect In field trials, a wettable powder of strain AP6 combined with commercial metalaxyl-M and fludioxonil significantly reduced the incidence of brown rot in yam.
Recommendation The authors conclude B. velezensis AP6 is a promising biocontrol agent offering a practical, sustainable approach to integrated disease management in yam.
