To control Phytophthora blight of red pepper biologically caused by Phytophthora capsici, we developed Trichoderma harzianum DYMC for commercial product. DYMC was storage at room temperature and was investigated their population every 3 months for 1 year. For investigating the dynamic population of T. harzianum in the pot soils, we applied powder and suspension applications with DYMC, and then investigated for 95 days. The efficacy of powder and suspension applications of DYMC for control of Phytophthora blight of red pepper and plant growth were investigated for 50 days in greenhouse experiment. The population of T. harzianum was decreased at the room temperature for 1 year but there was not statistically significance. After soil treated in the pot with DYMC, the population of Trichoderma spp. was the highest when DYMC powder at 5 g was applied to mix with pot soil, and the population was deceased significantly among treatment means as time goes by ($R^2
