Different species of Trichoderma especially T. harzianum (Th2 biotype in Europe and Th4 in America) considered as causal agent of green mould disease on button mushroom (Agaricus bisporus) casing beds. In this study, 100 fungal isolates were collected and purified from different mushroom growing units in Tehran province and Urmia (NW Iran). Totally, 60 isolates of T. harzianum, 27 isolates of T...

Pot experiment was conducted to find out the competence of some commercial product Trichoderma spp. on management root knot nematode in tomato crop. The RCBD having seven treatments six different including one control three replications. Each treatment had five pots. Twenty days old seedling Shrijana hybrid transplanted and inoculated with 1500 eggs Meloidogyne soil after transplanting seedling...

Banded leaf and sheath blight (BLSB) of maize (Zea mays L.) caused by Rhizoctonia solani f. sp. sasakii is one the most important yield-limiting factors faced growers in India. Therefore, attempts were made to identify promising suitable bioagents for management BLSB maize. Present study was carried out check efficacy two bioformulations, viz. Pusa Th3 (Trichoderma harzianum) Cg2 (Chaetomium gl...

Bioprotection de Cucumis melo contre maladie des taches foliaires par Glomus mosseae et Trichoderma harzianum. Alternaria alternata, responsable l’alternariose foliaires, est une propagation mondiale notamment en Irak. Cette se caractérise la formation lésions sur les feuilles, entraînant pertes substantielles rendement qualité chez plusieurs espèces végétales telles que (melon). harzianum sont...

abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...

Trichodermanins C-E (1-3), new diterpenes with a rare fused 6-5-6-6 ring system, have been isolated from a fungus Trichoderma harzianum OUPS-111D-4 separated from a piece of a marine sponge Halichondria okadai, and these chemical structures have been established by spectroscopic analyses using IR, MASS, HRFABMS, and NMR spectra. We established their absolute stereostructures by application of t...

Tandyukisins B-D (1-3), novel decalin derivatives, have been isolated from a strain of Trichoderma harzianum OUPS-111D-4 originally derived from the marine sponge Halichondria okadai, and their structures have been elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques. In addition, their chemical structures were established by chemical transformation. They exhibited w...

Verticillium wilt is a serious disease of pistachio caused by Verticilliumdahliae. Control of the disease is difficult due to soil borne nature of the causal agent. Verticillium wilt has been biologically controlled by Trichoderma spp. In the present study, Trichoderma spp. was isolated from soils of pistachio orchards and their effect was investigated on radial growth of Verticillium dahliae b...

Understanding the function of Trichoderma species in the control of Phytophthora drechsleri in pistachio orchards is very important.  In this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of Trichoderma harzianum, T. crassum, T. koningii, T.aureoviride, T. asperellum, T. brevicompactum, T.longibrachiatum and T. virens were investigated on ...
