Other claims from this paper (13)
- Intervention effect Fungal fermentation products achieved over 95% pinewood nematode mortality within six hours in laboratory assays.
- Intervention effect The metabolites enriched nematode-associated Serratia 20.2-fold.
- Intervention effect The metabolites enriched nematode-associated Delftia 6.0-fold.
- Intervention effect The metabolites inhibited Chryseobacterium with an 86.3% reduction.
- Intervention effect Nematicidal activity was abolished in axenic nematodes.
- Mechanism The loss of nematicidal activity confirms dependence on microbial modulation.
- Mechanism Serratia nematodiphila Ser-3 was identified as a critical mediating strain.
- Intervention effect High-dose sj18 trunk injection reduced pinewood nematode populations by 16.6–85.7% across six field sites.
- Intervention effect High-dose sj18 did not differ significantly from commercial emamectin benzoate at five field sites.
- Observation Bioactivity-guided fractionation identified 54 constituents.
- Mechanism Oligopeptides EQCSCPQ and DLYVMF were identified as key effectors.
- Mechanism Maltose was identified as a key effector.
- Mechanism The proposed mechanism involves bacterial nematicidal activity induced by specific oligopeptides and sugars.
