در طی مطالعه درباره بیماری ریزوکتونیایی سیب زمینی در سال 1385، از مزارع و انبارهای سیبزمینی استانهای همدان و کردستان، پنجاه جدایه با مشخصات قارچ rhizoctonia. solani از ساقه و ریشه و هشت جدایه از سختینه های موجود در سطح غده ها جداسازی شد. بعد از رنگ آمیزی هسته و بررسی های فیزیولوژیکی، تمام جدایه های تحت مطالعه با عنوان گونۀ r. solani شناسایی شدند. برای تعیین گروههای آناستوموزی جدایهها،...
An experiment was conducted to isolate a number of biocontrol agentTrichoderma spp. from infected spawn packets of oyster mushroom at National Mushroom Development and Extension Centre, Savar, Dhaka, Bangladesh. These bio-control agents were used as antagonist against four wild wood decay fungi of Ganoderma, viz., G. lucidum-1, G. lucidum-2, G. lucidum-3, G. applanatum and two cultivated G. luc...
damping-off of seedling is a major disease of cotton in iran. disease may become epidemic in soil with low temperature and high moisture if seed treatment isn’t done. recently, trichoderma spp. are considered as one of the biological control methods of seedling damping-off. one proposed mechanism for biocontrol in trichoderma spp. is stimulation of host defense responses and induction of resist...
An isolate of Trichoderma harzianum Rifai from an infected cacao pod produces and secretes nonanoic (pelargonic) acid into a liquid culture medium. Nonanoic acid (NA) was very inhibitory to spore germination and mycelial growth of two cacao pathogens, Crinipellis perniciosa Stahel and Moniliophthora roreri Cif. H.C. Evans. It was highly active causing 75% inhibition of spore germination in an i...
The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...
Lentinula edodes, one of the most important edible mushrooms in China, is affected heavily by the infection of green mold that overgrows mushroom mycelia. We collected the diseased samples from main L. edodes cultivation regions in China to characterize the pathogen and to study the effect of Trichoderma spp. on L. edodes species. We identified six Trichoderma species, that is, T. harzianum, T....
GOCHEV, V. K. and A. I. KRASTANOV, 2007. Isolation of laccase producing Trichoderma spp. Bulg. J. Agric. Sci., 13: 171-176 Based on its dye decolorization activities four Trichoderma strains were screened as laccase producers. The strains were identified as T. atroviride, T. longibrachiatum, T. reesei, and T. viride. It was determined that it was expedient to screen laccase producing Trichoderm...
We describe the second known case of human infection by Trichoderma harzianum. A disseminated fungal infection was detected in the postmortem examination of a renal transplant recipient and confirmed in culture. The only other reported infection by this fungus caused peritonitis in a diabetic patient. The in vitro antifungal susceptibilities of the clinical strain and three other strains of Tri...
The aim of this study was to determine the accuracy of monoclonal antibodies (mAbs) in identifying culturable allergenic fungi present in visible mould growth in energy efficient homes, and to identify risk factors for exposure to these known allergenic fungi. Swabs were taken from fungal contaminated surfaces and culturable yeasts and moulds isolated by using mycological culture. Soluble antig...
چکیده : trichoderma spp. به عنوان یکی از عوامل کنترل بیولوژیکی موثر بر علیه دامنه وسیعی از پاتوژنها مانند macrophomina phaseolina (tassi) goid شناخته می شود که از طریق استراتژی های گوناگونی از جمله تولید آنزیمهای تجزیه کننده دیواره سلولی (کیتیناز و گلوکاناز) فعالیت می کند. یکی از عوامل محدود کننده کاربرد جدایه های تریکودرما به عنوان عامل کنترل بیولوژیکی، پایین بودن میزان تاثیر آن در سطح مزرعه ...
