Abstract
The Trichoderma asperellum T10 isolated from soil for dragon fruit growth in Binh Thuan province, has a strong antagonistic ability against the Neoscytalidium dimidiatum, causing the white spot disease on dragon fruit. The results showed that T. asperellum T10 had a high antagonistic effect against fungal pathogens of 100%, and the inhibitory zone diameterreached 28.00 mm in laboratory conditions. T. asperellum T10 has been influential in the prevention and treatment of white spot disease in greenhouse conditions and reducing disease rates by 28-40% and disease index by 23-33% compared to the control. T. asperellum T10 is proposed as a potential strain of a microbial product for the prevention and treatment of white spot disease on dragon fruit.
