Biological control agents for plant diseases are currently being examined as alternatives to synthetic pesticides due to their perceived increased level of safety and minimal environmental impacts. Fungal biological control agents have several mechanisms of action that allow them to control pathogens, including mycoparasitism, production of antibiotics or enzymes, competition for nutrients and ...
The presence of phorbol esters (PEs) with toxic properties limits the use of Jatropha curcas kernel in the animal feed industry. Therefore, suitable methods to detoxify PEs have to be developed to render the material safe as a feed ingredient. In the present study, the biological treatment of the extracted PEs-rich fraction with non-pathogenic fungi (Trichoderma harzianum JQ350879.1, T. harzian...
این پژوهش به منظور بررسی اثر برخی جدایه های trichoderma spp. به عنوان افزایش دهنده رشد گیاهچه های خیار(cucumis sativus l.) در شرایط گلخانه اجرا گردید. اینوکولوم های 19 جدایه قارچ تریکودرما با استفاده از بذر گندم سترون تهیه گردید. نیمه بالایی خاک گلدان ها (حاوی خاک مزرعه و ماسه) به نسبت 3% وزنی با این اینوکولوم ها مخلوط گردید و گلدان ها به مدت 28 روز با آب شهری آبیاری شدند. سپس همه گیاهچه ها پس ...
Acipenser stellatus is one of the most invaluable species of Sturgeon fishes in the world. The purpose of this study was to identify the resident microbial community from the gastrointestinal tract (GIT) of Acipenser stellatus. One hundred and twenty three fungi were isolated from the GIT of 7 Acipenser stellatus samples including Aspergillus spp (45.5%), Trichoderma spp (8.9%) and Cladophialop...
اسپور بسیاری از کپک ها قادر به کلونیزه شدن و تندش بر روی سطح خارجی اپیدرم میوه سیب می باشند. تراکم بالای اسپور و قطعات ریسه نقش مهمی در فساد این میوه دارد. این میکروارگانیسم ها تا حدود 70% از بیماری های پس از برداشت سیب (post harvest disease) را سبب می شوند. به همین دلیل، در این بررسی، کلونیزاسیون سطح سیب توسط کپک ها در میوه های جمع آوری شده از محل های عرضه در شهر تهران (تره بار) و باغ مقایسه...
Olive (Olea europaea) is a crop of great agronomic, economic and cultural interest for the Mediterranean Basin, although increase in world demand olive oil expanding its cultivation by other countries southern hemisphere. The main pathogens include bacteria (Pseudomonas savastanoi pv. savastanoi, Xylella fastidiosa), fungi (Colletotrichum spp., Verticillium dahliae, Fusarium spp. Rhizoctonia so...
Samuels, G. J. 2006. Trichoderma: Systematics, the sexual state, and ecology. Phytopathology 96:195-206. A chronology is presented that charts the development of a genus and species concept in Trichoderma. Eighty-nine species of Trichoderma have been named, and several species of Hypocrea have been linked to unnamed Trichoderma anamorphs. Eighty-three taxa of Trichoderma and their teleomorphs, ...
