The tomato plant is usually infected with various pathogens such as pests, bacteria, and different mycoflora. In this investigation, Tomato cultivar Beeli was pathogenized Fusarium oxysporum f.sp. Lycopersicon (FOL1) fungi. FOL1 fungus controlled by inoculating the plants each one of biocontrol microorganisms, Arbuscular mycorrhiza (AM), Trichoderma harzianum (T. harzianum), microbial blend, na...

The enzymes from Trichoderma species that degrade fungal cell walls have been suggested to play an important role in mycoparasitic action against fungal plant pathogens. The mycoparasite Trichoderma harzianum produces at least two extracellular beta-1,6-glucanases, among other hydrolases, when it is grown on chitin as the sole carbon source. One of these extracellular enzymes was purified to ho...

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...

Compatibility of the entomopathogenic fungus, Metarhizium anisopliae with representative pesticides, plant oils and a fungal antagonist were studied in vitro. The pesticides tested were: endosulfan, acephate, abamectin, ethion, chlorothalonil, iprodion + carbendazim, thiophanate methyl and dinocap, an antagonist, Trichoderma harzianum and the plant oils: coconut oil, groundnut oil, gingili oil,...

Many fungal root symbionts of the genus Trichoderma are well-known for their beneficial effects on agronomic performance and protection against plant pathogens; moreover, they may enhance protection from insect pests, by triggering plant resistance mechanisms. Defense barriers against insects are induced by the activation of metabolic pathways involved in the production of defense-related plant...

In this study, seven Trichoderma species (33 strains) were classified using secondary metabolite profile-based chemotaxonomy. Secondary metabolites were analyzed by liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS) and multivariate statistical methods. T. longibrachiatum and T. virens were independently clustered based on both internal transcribed spacer (ITS...

Mutanase (α-(1→3)-glucanase) is a little-known inductive enzyme that is potentially useful in dentistry. Here, it was shown that the cell wall preparation (CWP) obtained from the fruiting body or vegetative mycelium of polypore fungus Laetiporus sulphureus is rich in α-(1→3)-glucan and can be successfully used for mutanase induction in Trichoderma harzianum. The content of this biopolymer in th...
