The concentration of powder extract of extract mangosteen rind used were: 0%, 5%, 15%, 25% and 35%. The data were statistically analyzed using analysis of variance and the means were compared with Duncan 's New Multiple Range Test (DNMRT) at level of 5%. The results of the research showed that the concentration of powder extract of mangosteen rind  significantly affected C. capsici growth and increase the percentage of fungal growth inhibition. Powder extract of mangosteen rind at concentration 35%  gave the best effect in controlling anthracnose disease on red chilli fruits, which resulted in a longer incubation period of the disease, a lower intensity of the disease namely 23,70% and the effectiveness as a botanical fungicide is 60,47%. Key words : Red chili, the concentration and Garcinia mangostana.
