The antagonistic effect of Trichoderma harzianum on a range of seed-borne fungal pathogens of wheat (viz. Fusarium graminearum, Bipolaris sorokiniana, Aspergillus spp., and Penicillium spp.) was assessed. The potential of T. harzianum as a biocontrol agent was tested in vitro and under field conditions. Coculture of the pathogens and Trichoderma under laboratory conditions clearly showed domina...

A resurgence of interest in biological control of wood decay fungi due to recent revelations of its beneficial effects in protective wooden structures against decay fungi is in enormous increase. This has also been due, in large part, to increase public awareness and concern over the environmental impact of currently used chemical wood preservatives. Mechanisms of control, which have been attri...

is the major bacterial disease in tomato, Background: Ralstonia solanacearum which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. R. produces several toxins helping it to invade the plant’s natural solanacearum defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used as...

trichoderma species are among important antagonists of plant pathogenic fungi. the main purpose of this study was to evaluate the biocontrol potential of native trichoderma spp. isolates from sugar beet fields against phytophthora drechsleri and p. cryptogea, the causal agents of phytophthora root rot of sugar beet. during 2007–08, 85 isolates of trichoderma spp. from sugar beet fields in eight...

OBJECTIVES The uncommon fungal pathogen Trichoderma shows increasing medical importance particularly in immunocompromised patients. Despite systemic antifungal therapy, prognosis of Trichoderma infection is poor regardless of the type of infection and the therapy used. The aim of the present study was to evaluate the in vitro activity and synergism of double antifungal combinations including am...

S: Fusarium solani and Rhizoctonia solani are the common causal pathogens causes the damping off disease of beans (Phaseolus vulgaris L.) in Egypt. The antagonistic effect of four Trichoderma species, i.e. Trichoderma album, Triechoderma hamatum, Trichoderma harzianum and Trichoderma viride, was tested against F. solani and R. solani in vitro, in greenhouse and in field. In vitro tests, all Tri...
