In vitro – In vivo efficacy of Trichoderma asperellum and Trichoderma virens against Ganoderma boninense in oil palm seedlings

Key Points

• This research assesses the effectiveness of Trichoderma asperellum and Trichoderma virens in controlling Ganoderma boninense in oil palm seedlings.
• Conducted in vitro and in vivo tests to evaluate antifungal activity.
• Assessed strain stability and performance in nursery settings.
• Analyzed physiological competition effects between strains.
• Identified key strains that demonstrated consistent antifungal activity against Ganoderma.
• Found that strain compatibility significantly affects biocontrol efficacy.
• Noted that variation in strain performance may arise from physiological competition.
