Soil-borne diseases are the cause of severe losses of economically important crops. Chemical pesticides have been widely used for several decades to control soil-borne pathogens. As far as health and environment concerns, application of biological control agents is one of the eco-friendly alternative approaches to chemical pesticides. In this context, soil is the reservoir of different biological control organisms. Trichoderma spp. are the most commonly using biological control agents iN habiting in various types of soil. Efforts have been made for isolation of Trichoderma spp. from soil samples collected from the fields cultivated with different crops. Ninty isolates of Trichoderma spp. have been isolated either by direct soil plating or by serial diluton plate technique on potato dextrose agar medium………………………….
