Biocontrol of strawberry Botrytis gray mold and prolong the fruit shelf-life by fumigant Trichoderma spp.

Objectives To screen high active volatile organic compounds (VOCs)-producing Trichoderma isolates against strawberry gray mold caused by Botrytis cinerea, and to explore their antagonistic mode of action against the pathogen. VOCs produced by nine Trichoderma isolates (Trichoderma atroviride T1 and T3; Trichoderma harzianum T2, T4 and T5; T6, T7, T8 and T9 identified as Trichoderma asperellum in this work) significantly inhibited the mycelial growth (13.9−63.0
