<p>The Phytophthora pod rot (PPR) caused by <em>Phytophthora palmivora </em> is one of important diseases affecting the decrease of cacao productivity. The use of endophytic Trichoderma have a big potential for controlling this disease. The rate of PPR incidence in twelve weeks after three times application by spraying of ART-4/G.J.S 09-1559 isolate of <em>Trichoderma asperellum</em> with concentration of 1 g L^-1, 2 g L^-1, 4 g L^-1 was 5.4%, 5.3%, and 3.7%, respectively per week; while the rate of PPR incidence on control was 8.4% per week. Apparently healthy pods pretreated with above concentrations of <em>T. asperellum</em> in field showed 30, 0, and 0% infested by PPR on its surface, respectively after one week incubation in laboratory, compared to a 90% of surface infestation by PPR on control. After 12 week of inoculation, <em>T. asperellum</em> was recovered from pod tissue. This data demonstrated the potential of <em>T. asperellum</em> as bio control agent of PPR disease on cacao.</p> <p> </p>
