Members of the species-rich Fusarium solani species complex (FSSC) are responsible for approximately two-thirds all fusarioses of humans and other animals. In addition, many economically important phytopathogenic species are nested within this complex. Due to their increasing clinical relevance and because most of the human pathogenic and plant pathogenic FSSC lack Latin binomials, we have exte...
افزایش مقاومت عوامل بیماریزا به سموم و تاثیر سوء زیست محیطی قارچکشها، نیاز به پژوهش در راستای مواد جدید ضدقارچی که تجدید شونده و سازگار با محیطزیست باشند را ضروری مینماید. بر این اساس، فعالیت ضدقارچی اسانس نه گیاه دارویی آویشن کرمانی، آویشن شیرازی، سیر، سریش، زیرهسبز، نعناع، مرزه، چریش و fusarium اسطوخودوس روی سه قارچ خاکزاد عامل بیماری پوسیدگی های ریشه و طوقه گوجه فرنگی به روش اختلاط اسانس...
We compared the in vitro pharmacodynamics of amphotericin B, itraconazole, and voriconazole against Aspergillus, Fusarium, and Scedosporium species with a combination of two non-culture-based techniques: the tetrazolium salt 2,3-bis-(2-methoxy-4-nitro-5-[(sulfenylamino)carbonyl]-2H-tetrazolium-hydroxide) (XTT) colorimetric reduction assay, and fluorescent microscopy with the cellular morbidity ...
S: Fusarium solani and Rhizoctonia solani are the common causal pathogens causes the damping off disease of beans (Phaseolus vulgaris L.) in Egypt. The antagonistic effect of four Trichoderma species, i.e. Trichoderma album, Triechoderma hamatum, Trichoderma harzianum and Trichoderma viride, was tested against F. solani and R. solani in vitro, in greenhouse and in field. In vitro tests, all Tri...
A total of 198 cereal samples (53 maize, 54 sorghum, 37 paddy and 54 wheat) were collected from 11 districts of Karnataka to understand the percent infection (PI), relative density (RD) and their frequency (Fr) caused by Fusarium spp. All samples were screened by agar plating method using MGA 2.5 agar media and incubated at 25 ± 2 °C for 3-5 days. The study revealed the association of 10 differ...
Bu çalışmada, nane yetiştiriciliğinde önemli hastalıklara sebep olan fungal patojenlerden Fusarium oxysporum ve Rhizoctonia solani' ye karşı Trichoderma harzianum virens biyolojik kontrol etmenlerinin etkisi araştırılmıştır. aşamada solgunluk belirtisi gösteren bitkilerinin köklerinden yapılan izolasyonlar sonucunda F. R. solani izolatları elde edilmiş tanıları yapılmıştır. In vivo’da T. biyoet...
جهت شناسایی قارچ های عامل پوسیدگی طوقه و ریشه ی چغندرقند در سال زراعی 91-92 و تعیین الگوی پراکنش در مزارع چغندرکاری استان لرستان ، ضمن بازدید از مناطق عمده کشت چغندرقند، نمونه برداری از گیاهان دارای علائم پژمردگی و پوسیدگی ریشه چغندرقند انجام شد. قطعات جدا شده از حد فاصل بافت های کشت شدند. (pda) آلوده و سالم، پس از ضدعفونی سطحی روی محیط عصاره سیبزمینی، دکستروز و آگار خصوصیات ریخت شناسی جدایه ها...
Chitosan (CS)-g-poly (acrylic acid) (PAA) nanoparticles, which are well dispersed and stable in aqueous solution have been prepared by template polymerization of acrylic acid in chitosan solution. The prepared CS-PAA had a white powder shape and was insoluble in water and diluted acid. The mean particles size were found to be around 50nm. FTIR spectra of CS-PAA nanoparticles for CS, the intensi...
Fusarium is a cosmopolitan and highly diversified genus of saprophytic, phytopathogenic and toxigenic fungi. However, the existence and diversity of a few species of Fusarium are restricted to a certain area or climatic condition. The present study was conducted to determine the occurrence and diversity of Fusarium species in tropical highland areas in Malaysia and to compare with those in temp...
AIMS/BACKGROUND The purpose of this study was apply the polymerase chain reaction (PCR) to develop a sensitive, specific, and rapid test to diagnose Fusarium keratitis. Fusarium is the most common cause of fungal corneal infection in some parts of the world. It is often difficult to establish that a keratitis is due to fungal infection. METHODS Fusarium solani keratitis was induced in three e...
