Abstract

Culture filtrates of Trichoderma harzianum Rifai have been found to inhibit zoospore germination, germ tube elongation and mycelial growth of Pythium aphanidermatum causing the damping-off disease of tobacco in Nigeria. Further, the invasion of the hyphae of P. aphanidermatum by hyphae of T. harzianum has been demonstrated in mixed cultures of the two fungi. The results of investigations on the role of T. harzianum as an agent of biological control of the damping-off disease in sterilized and unsterilized soils are reported and discussed.
