this study was carried out to identify fusarium species associated with sugar beet root rot and yellows. pathogenicity of fusarium oxysporum, the causal agent of fusariumyellows of sugar beet was also investigated. samples of infected roots were collected from fields in major sugar beet producing areas in khorasan province during 1999-2000. infected roots were washed, surface sterilised and pla...

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...

Using the seed-plate technique, 18 different isolates of Fusarium moniliforme were isolated on pentachloronitrobenzene (PCNB) agar medium from 18 samples of a local variety of corn collected from locations in Minia Governorate. The isolates of F. moniliforme were screened for their ability to produce fumonisins on polished rice grains using the solid state fermentation technique. Based on thin ...

Fumonisins are mycotoxins produced by Fusarium moniliforme, a common fungal contaminant of corn worldwide, 10 and F. proliferatum, a closely related species.l.Io.'9 The true incidence of F. moniliforme is difficult to determine because F. proliferatum has often been misidentified as F. moniliforme. lO,'3 Certain strains of F. proliferatum also produce moniliformin, but isolates of F. moniliform...

Fusarium moniliforme (F. moniliforme) is one of the most frequent fungal pathogens found in rice. Samples of rice grown in three different zones of Mazandaran Province, Iran were collected and analyzed for the presence of fumonisin B (FB ). Mycological analysis revealed the presence of F. moniliforme-type isolates 1 1 in 65.1% of the rice samples. Average levels of FB per zones 1, 2 and 3 were ...

A Spore killer trait, which exhibits genetic and cytological properties analogous to those previously found in Neurospora, exists in natural populations of the fungal plant pathogen Fusarium moniliforme. The genogeography of the polymorphism in F. moniliforme differs from the situation in Neurospora intermedia. It is more akin to the situation in N. sitophila, although more extreme with respect...

Fumonisins B1 (FB1) and B2 (FB2), two structurally related mycotoxins with cancer-promoting activity, were recently isolated from corn cultures of Fusarium moniliforme MRC 826. These toxins have been reported to be produced also by isolates of F. proliferatum. Contamination of foods and feeds by F. moniliforme has been associated with human esophageal cancer risk, and FB1 has been shown to be t...

The ability of Fusarium species isolated from bananas to produce mycotoxins was studied with 66 isolates of the following species: F. semitectum var. majus (8 isolates), F. camptoceras (3 isolates), a Fusarium sp. (3 isolates), F. moniliforme (16 isolates), F. proliferatum (9 isolates), F. subglutinans (3 isolates), F. solani (3 isolates), F. oxysporum (5 isolates), F. graminearum (7 isolates),...

Maize kernel samples were collected in 1996 from smallholder farm storages in the districts of Bomet, Bungoma, Kakamega, Kericho, Kisii, Nandi, Siaya, Trans Nzoia, and Vihiga in the tropical highlands of western Kenya. Two-thirds of the samples were good-quality maize, and one-third were poor-quality maize with a high incidence of visibly diseased kernels. One hundred fifty-three maize samples ...

Fusarium subglutinans f. sp. pini (= F. circinatum) is a pathogen of pine and is one of eight mating populations (i.e., biological species) in the Gibberella fujikuroi species complex. This species complex includes F. thapsinum, F. moniliforme (= F. verticillioides), F. nygamai, and F. proliferatum, as well as F. subglutinans associated with sugarcane, maize, mango, and pineapple. Differentiati...
