What does the published scientific research say about Trichoderma asperellum?

Beyond pathogen suppression, published research reports that T. asperellum isolates promote tomato seedling growth — including increased height, stem diameter, soluble protein, and nitrogen uptake — and that application prior to F. oxysporum or F. commune inoculation improved biocontrol outcomes in blueberry root rot trials. A Kenya field study found T. asperellum application was associated with improved soil health indices and microbial community diversity in coffee plantations infested with Meloidogyne hapla.

Formulation research indexed in PubMed addresses a recognized challenge: T. asperellum biocontrol efficiency can be unstable in field conditions. Sodium alginate microencapsulation achieved 76% biocontrol efficiency against cucumber powdery mildew in greenhouse trials, while submerged cultivation studies identified peat-based storage with Tween 80 addition as a route to extending shelf life over 12 months.
