The Trichoderma disease, commonly referred to as green mold, has been previously considered as a problem in mushroom production, because it typically occurred in association with low-quality compost or poor hygiene. We studied growth of Trichoderma spp. (Trichoderma aggressivum, Trichoderma atroviride, Trichoderma harzianum, Trichoderma koningii, Trichoderma viride) is under the control of environment factors ; 15℃ - 35 ℃ of incubation temperature, pH 3 - pH 11 of medium and 55% - 75% moisture content of rice straw medium. At the temperature of incubation, Trichoderma spp. had the highest growth rate at 25 ℃ and had no growth at 35 ℃. At the pH of medium, Trichoderma spp. had the highest growth rate at pH 5 and had the lowest growth rate at pH 11. In the Moisture content of rice straw medium, Trichoderma spp. had the highest growth at 75% moisture content and had the lowest growth rate at 55% moisture content.
