- Intervention effect Pre-treatment with strain WCH05 significantly decreased pear blossom blight incidence in detached inflorescence assays.
- Intervention effect Strain WCH05 pre-treatment gave a 76.02% controlled efficacy against pear blossom blight, which rivaled the antibiotic streptomycin (79.79%).
- Intervention effect In greenhouse trials, strain WCH05 reduced the wilting rate and disease index in young pear seedlings.
- Intervention effect Strain WCH05 gave 73.68% protective control of pear seedlings in greenhouse trials.
- Intervention effect Strain WCH05 gave 68.66% curative control of pear seedlings in greenhouse trials.
- Mechanism The biocontrol activity of strain WCH05 relies on both direct contact and extracellular enzyme secretion.
- Observation Cell extracts of strain WCH05 lacked inhibitory activity.
- Observation Substrate spectrum analysis identified peptidases, lipases and glycosidases among the secreted enzymes of strain WCH05.
- Observation In plate predation assays, strain WCH05 showed strong predation against E. amylovora and broad-spectrum activity against other plant pathogenic bacteria.
