We have isolated three novel strains of Trichoderma (two T. harzianum and one T. atroviride) from wild mushroom and tree bark, and evaluated their biocontrol potential against Sclerotium delphinii infecting cultivated cotton seedlings. T. harzianum strain CICR-G, isolated as a natural mycoparasite on a tree-pathogenic Ganoderma sp. exhibited the highest disease suppression ability. This isolate...
Trichoderma harzianum is one of the most beneficial microorganisms applied on diverse crops against biotic and abiotic stresses and acts also as a plant growth-promoting fungus. Here, we report the genome of T. harzianum B97, originating from a French agricultural soil and used as a biofertilizer that can tolerate abiotic stresses.
ورمی کمپوست کودی است که از تجزیه میکروبی و ثبات مواد آلی در اثر فعالیت مشترک کرم های خاکی (eisentia foetida) و میگروارگانیسم های مختلف بدست می آید. ورمی کمپوست دارای خصوصیات فیزیکو شیمیایی مناسب بوده و از نظر عناصر غذایی قابل جذب غنی می باشد. گونه های متعلق به جنس قارچی trichoderma از جمله قارچ های متداول و غالب در خاک، مواد و بقایای گیاهی خشبی و سبز در حال پوسیدن به شمار می روند. قارچ trichode...
Phylloplane fungi of Chlorophytum tuberosum were screened for their antagonistic activities against Colletotrichum dematium in vitro. Volatiles produced from the cultures of Trichoderma harzianum ISO-1 showed maximum inhibition of mycelial growth of C.dematium followed by T. piluliferum, T. harzianum ISO-2 and Aspergillus niger,
در این بررسی، فعالیت بیوکنترلی جدایهی bi harzianum trichoderma علیه meloidogynejavanica و توانایی آن در القاء سیستم دفاعی در گیاه گوجه فرنگی رقم ارلی اوربانا y در آزمایشگاه و گلخانه بررسی شد. ریشه ی گیاهچه های گوجهفرنگی در مرحله ی 6 برگی توسط سوسپانسیون اسپور bi harzianum .t با غلظت 106 اسپور در میلیلیتر و تعداد 2000 لارو فعال سن دو نماتد به ازاء هر گیاه مایه زنی گردید. میزان فعالیت آنزیم...
A new species of Trichoderma (teleomorph Hypocrea, Ascomycota, Sordariomycetes, Hypocreales, Hypocreaceae), T. amazonicum, endophytic on the living sapwood and leaves of Hevea spp. trees is described. Trichoderma amazonicum is distinguished from closely related species in the Harzianum clade (e.g. Hypocrea alni, H. brunneoviridis, H. epimyces, H. parepimyces, T. aggressivum, T. harzianum, T. pl...
The antibiotic activity of 70 isolates belonging to the genera Aspergillus, Penicillium, Fusarium, Alternaria and Trichoderma was tested as preliminary screening. The highest activity was obtained with three Penicillium oxalicum isolates, one Penicillium decumbens isolate and the Trichoderma harzianum isolate. After that, we chose these five isolates in order to carry out other studies with bac...
Members of genus Trichoderma are known worldwide for mycoparasitism. To gain a better insight into the organization and evolution of their genomes, we used an in silico approach to compare the occurrence, relative abundance and density of SSRs in Trichoderma atroviride, T. harzianum, T. reesei, and T. virens. Our analysis revealed that in all the four genome sequences studied, the occurrence, r...
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...
Tolerance of Trichoderma species collected from tea plantation to fungicides was evaluated in vitro using poisoned food method. Fungicides like Carbendazim 50 WP, Copperoxychloride 50 WP, Hexaconazole 5 EC, and Propiconazole 25 EC were used at two lower and two upper of recommended doses. The growth of T. harzianum was mostly inhibited by the Carbendazim 50 WP and Propiconazole 25 EC with the r...
