Echinochloa spp. are the most important weeds in rice fields. In this research Fusarium equiseti and Colletotrichum graminicola were isolated from these weeds and then their pathogenicity effects were compared on these weeds and five rice cultivars in a completely random design with three replications in greenhouse conditions. Fungi were inoculated on weeds and rice cultivars using a spore susp...

Pathogenic effects of 6 Fusarium spp., viz., F. equiseti, F. longipes, F. scirpi (Section Gibbosum), F. oxysporum (Section Elegans), F. pallidoroseum (Section Arthrosporiella) and F. solani (Section Martiella) were studied on sunflower plants. Symptoms produced by Fusarium spp., were root-, collar-, stemand seedling rots, damping-off, stunting, wilting, tip burning and reduction in growth. Wilt...

Fusarium equiseti and Fusarium acuminatum are toxigenic species that contaminate cereal crops from diverse climatic regions. They are common in Spanish cereals. The information available on their phylogenetics and toxigenic profiles is, however, insufficient to assist risk evaluation. In this work, phylogenetic analyses were performed using partial sequences of the translation elongation factor...

The mycotoxin fusarochromanone, a metabolite of Fusarium fungi, is able to induce tibial dyschondroplasia (TD) in chickens under experimental conditions. On the basis of health surveillance data on TD, two broiler farms with TD prevalence rates of up to 56% were identified. In the corresponding pelleted feed samples, fusarochromanone was detected in all 12 samples analyzed by column purificatio...

Fusarium equiseti and F. pallidoroseum are frequently reported as secondary colonizers of plant tissues. In this study they were isolated from the embryos of weathered cottonseed. Most isolates tested produced equisetin, an antibiotic, when grown on potato dextrose agar, rice, surface-sterilized cottonseed, or autoclaved cottonseed. This is the first report of equisetin from F. pallidoroseum. E...

to identify the fungi associated with foot and root rot of wheat in the khuzestan province, diseased samples were collected at all growth stages in three growing seasons of 2004-2007. pieces of infected parts of the root and foot were surface sterilized and cultured on acidic and non acidic pda media. one hundred and fifteen isolates were obtained and on the basis of macroscopic and microscopic...

Four new moniliformin-producing species of Fusarium were found, viz., F. acuminatum, F. concolor, F. equiseti, and F. semitectum. Isolates of F. acuminatum and F. concolor produced large amounts of moniliformin (3.4 and 9.5 g/kg, respectively), whereas isolates of the other three species yielded less than 30 mg/kg. The production of moniliformin by isolates of F. oxysporum and F. avenaceum from...
