have favorable antagonistic activity against insects and pathogens
associated with many important plants and crops [48,49]. Many
chemical fumigants are used to control plant disease at present
[50], but they could change the biological equilibrium [51], such as eradicating beneficial organisms [52] and increasing pathogen
populations [53]. Nonchemical methods that effectively control
plant diseases are highly desirable. The results give us insight that
the deactivated cell walls of pathogenic fungi could be an effective
activator for T. gamsii YIM PH30019 to produce more VOCs that
inhibit the growth and metabolism of pathogenic fungi. This
interesting phenomenon warrants further investigation in ongoing
studies.
