Trichoderma spp. has been known as one of antagonist fungi and biocontrol agent of several plant diseases. In this research, Trichoderma isolates were tested for their potential as on inhabiting the growth of Phytophthora palmivora. The experiments consisted of in vitro test whereas each of Trichoderma isolate was confronted to P. palmivora grown in PDA and in planta test using cacao pods in the laboratory. Potential inhibition of each Trichoderma isolate on P. palmivora growth was determined based on the compilation of P. palmivora growth on media in the presence of Trichoderma and the absence of Trichoderma. The results confirmed that all of seven tested isolates can significantly inhibited the in vitro growth of P. palmivora , and the persentage of inhibition were higher than 50%. In planta test, however, the results were not consistently revealed that Trichoderma isolates were capable of inhibiting the development of cacao pod rot disease symptom. Based on antagonist classification, isolates of T. viride and isolate from Pringsewu can be classified as Class 2 antagonist, whereas the other five isolates can be grouped as Class 1 antagonist.
