TL;DR
A fermented botanical product helps plants resist soil-borne diseases by boosting lignin production, which acts as a natural barrier against pathogens.
Contribution
The study shows that FBP suppresses soil-borne bacterial diseases by promoting lignin development in plants.
Findings
FBP-treated plants showed fewer wilting symptoms and fewer dead plants after pathogen inoculation.
FBP increased lignin levels in Solanaceae plants, suggesting a physical defense mechanism against pathogens.
Similar suppression of disease was observed against multiple soil-borne bacterial species.
Abstract
Soil-borne plant pathogens are a significant cause of economic loss in global agriculture. In a previous study, fermented botanical product (FBP) treatment was shown to suppress bacterial wilt disease caused by Ralstonia pseudosolanacearum (Rps) in tomatoes. This study evaluated whether treatment with FBP suppresses soil‑borne bacterial pathogens and induces host plant defense responses. Seedlings of three Solanaceae species and nine families of plants treated with water or FBP for 48 h were inoculated with Rps and wilting symptoms were compared 14 days post inoculation. FBP treated plants showed an increase in the number of individuals without wilting symptoms and a decrease in the number of dead individuals. In addition, inoculation with C. michiganensis subsp. michiganensis, which belongs to the same soil-borne bacterial disease group, showed similar suppression in tomatoes treated…
