Red pepper is seriously damaged by thrips () and anthracnose caused by throughout its development. Because of biotic constraints, producers often depend on chemicals that are expensive and have adverse effects on the environment, operator, and beneficial insects. In addition, resistance is developed because of the repeated use of chemicals. In recent decades, the use of microorganisms in crop protection has become a credible alternative because it is eco-friendly. In this study, we aimed to select isolates with insecticidal and fungicidal activities against the pathogens that cause anthracnose and thrips. We treated T. palmi adults and juveniles with 13 strains of entomopathogenic fungi (isolated from the soil by using the insect-bait method), and 6 strains showed excellent insecticidal activity (70–100%) 5 days after the treatment. The selected isolates were cultured with to screen for the strain with excellent anti-fungal activities, and the isolate FT333 showed more than 95% control efficacy against in vitro. The isolate was identified as through its morphological characteristics and phylogenetic analysis of the ITS and β-tubulin nucleotide sequences. The FT333 isolate could be used effectively for dual bio-control of thrips and anthracnose during red pepper cultivation.
