Species of the genus Trichoderma sp. are considered as potential biocontrol agents (BCA) for many plant diseases. The effectiveness of biocontrol agents depends on several parameters therefore their application showed consider climatic factor that could affect their biocontrol capacity.The present study examined the antagonistic potential of two Trichoderma sp. strains (Td85 and Td50) against Rhizoctonia solani depending on pH (4.5;5.5) and temperature (25°C, 30°C). Both strains of Trichoderma sp. studied inhibit stronger growth of Rhizoctonia solani at 30°C compared to 25°C. Also our results revealed that both strains of Trichoderma have maximum antagonistic ability to Rhizoctonia solani strain at pH=4.5.
