The destructive parasitic mode in Trichoderma, a natural antagonist to other fungi and well-known biocontrol agent of plant pathogenic fungi, appears to be a complex process, made up from several successive steps. Upon contact with the host Trichoderma coils around or grows along the host hyphae and forms hook-like structures that aid in penetrating the host’s cell wall (Chet, 1987). In Trichoderma, this reaction has been found to be rather specific (Dennis and Webster, 1971), and lectin-carbohydrate interactions were assumed to mediate the attachment and recognition between Trichoderma and soil-borne plant pathogenic fungi (Barak et al., 1985).
