Other claims from this paper (9)
- Observation The biocontrol isolate was identified as Trichoderma asperellum.
- Intervention effect Trichoderma asperellum XY101 strongly suppressed Vasal pyri mycelial growth on culture plates.
- Intervention effect XY101 VOCs caused abnormal changes in Vasal pyri mycelial ultrastructure.
- Intervention effect XY101 VOCs damaged fungal cell membrane integrity.
- Observation Twenty-four possible VOCs produced by XY101 were detected.
- Observation 3,7-dimethyl-1-octanol was identified as a primary antagonistic VOC affecting pear Valsa canker.
- Observation 1-octen-3-ol was identified as a primary antagonistic VOC affecting pear Valsa canker.
- Intervention effect The VOCs modulated Vasal pyri gene expression related to metabolism, membrane damage, pathogenicity and resistance.
- Recommendation The authors propose XY101 VOCs as a basis for biological fumigants against pear Valsa canker.
