Abstract
This study reported some species of the Chaetomiaceae from collected soil samples in Vietnam. Soil samples were taken from dragon fruit crop cultivation in Tien Giang and Long An provinces in 2017. All species of Chaetomiaceae were isolated from soil samples by soil baiting technique. All species were identified based on the morphological characteristics and phylogenetic analysis of β-tubulin gene. At least four species of the Chaetomiaceae family were identified, including Arcopilus aureus, Arcopilus cupreus, Chaetomium cochliodes and Chaetomium globosum. These strains were strongly antagonistic activity against Neoscytalidium dimidiatum causing brown spot disease of Hylocereus undatus (white-fleshed pitahaya) in Vietnam. Further research would be done the control mechanism and acute and dermal toxicology test for environmental safety. Finally it maybe formulate as biological fungicide to control this serious disease in the field.
