resistance of iranian lecanicillium fungicola to benzimidazole ‎and ergosterol demethylation inhibiting fungicides

Molecular mechanism of resistance of Fusarium fujikuroi to benzimidazole fungicides.

Although carbendazim (MBC) and other benzimidazole fungicides have effectively controlled bakanae disease of rice (which is caused by Fusarium fujikuroi, F. proliferatum, and F. verticillioides) in the past, MBC resistance has become common. Previous research has shown that MBC resistance results from a mutation in the β1 -tubulin (β1 tub) gene in F. verticillioides. However, MBC resistance in ...

Germination of Lecanicillium fungicola in the mycosphere of Agaricus bisporus.

Dry bubble disease is a major problem in the commercial cultivation of the white button mushroom Agaricus bisporus and is caused by the ascomycete Lecanicillium fungicola. In the casing layer, germination of L. fungicola spores is inhibited by the microflora, a phenomenon known as fungistasis. Fungistasis is annulled when the casing is colonized by A. bisporus hyphae. We demonstrated that addit...

Sensitivity of Sclerotinia homoeocarpa to demethylation- inhibiting fungicides in Ontario, Canada, after a decade of use

In late 2003, nine populations of Sclerotinia homoeocarpa in Ontario Canada (seven of which had been previously sampled in early 1994, prior to the registration of sterol demethylation-inhibiting (DMI) fungicides for turf disease control in Canada) were sampled and tested for sensitivity to propiconazole. Four of the nine populations had not been treated with DMI fungicides during the interveni...

Naturally Occurring Antidotes against Benzimidazole Fungicides

TLC bioautography using precoated glass thin-layer plates impregnated with benomyl or carbendazim (MBC), and Cladosporium herbarum as a test fungus was evaluated as a facil way to detect plant secondary m etabolites antidoting against benzimidazole fungicides. In ad­ dition to emodin and a-tocopherol from Polygonum sachalinense, three phenolics, 3,5-dihydroxy-4-methylstilbene and 5-methoxy-6,7-...

native speaker norms and teaching english to non_native speakers : the case of iranian efl learners

امروزه، این که زبان انگلیسی سریع ترین و گسترده ترین زبان مورد استفاده در سراسر جهان است به عنوان یک واقعیت پذیرفته شده است. استفاده مشترک از زبان انگلیسی به عنوان یک زبان بین المللی مستلزم هنجارها و مدل های یادگیری و تدریس زبان است. زبان شناسان توجه ویژه ای به مفهوم "زبان مادری" به عنوان تنها منبع درست و قابل اعتماد از داده های زبان می داده اند.با این حال، این اصطلاح به اندازه کافی روشن به نظر ...
