What benefits of Bacillus pumilus have been cited in the scientific literature?
The literature also reports Bacillus pumilus biocontrol activity against a range of fungal phytopathogens — including Fusarium solani, Fusarium oxysporum, Sclerotinia sclerotiorum, and Rhizoctonia solani — via lipopeptide production, hydrolytic enzymes, microbial volatile organic compounds, and induced systemic resistance. Against Meloidogyne incognita on tomato, inoculation has been reported to reduce root galling by 84.21% and lower nematode reproduction. Under salt and arsenic stress in wheat, B. pumilus inoculation has been reported to preserve relative growth rate, chlorophyll fluorescence, and photosystem II performance. These findings are from peer-reviewed research and do not constitute approved label claims or regulatory endorsements.
