This study aimed to determine the ability of  Trichoderma viride  PP2 culture filtrate concentration in suppressing anthracnose disease caused by  C. gloeosporioides  on the red chili pepper. The study was conducted with a randomized block design (RBD) consisting of 5 treatments and five replications. The treatments were the concentration of  T. viride  PP2 culture filtrate, i.e., 0% (control), 25%, 50%, 75% and 100%. Parameters observed were incubation period, percentage of infected, and infected intensity. The results showed that the application of filtrate of T. viride isolate PP2 with different concentrations has not been able to suppress the development of anthracnose disease caused by  C. gloeosporioides  in-planta. It is necessary to conduct further research on the effect of temperature and time application on suppressing the filtrate of T. viride isolate PP2.
