The increased occurrence of Fusarium-mycotoxins in Norwegian cereals over the last decade, is thought to be caused by increased inoculum resulting from more cereal residues at the soil surface as a result of reduced tillage practices. In addition, weather conditions have increasingly promoted inoculum development and infection by Fusarium species. The objective of this work was to elucidate the...

Fusarium graminearum is the pathogenic agent of Fusarium head blight (FHB), which is a destructive disease on wheat and barley, thereby causing huge economic loss and health problems to human by contaminating foods. Identifying pathogenic genes can shed light on pathogenesis underlying the interaction between F. graminearum and its plant host. However, it is difficult to detect pathogenic genes...

In South Africa, the main causal organisms of Fusarium head blight (FHB) are Gibberella zeae (=Fusarium graminearum), F. culmorum and F. crookwellense. Fusarium graminearum and F. culmorum are associated with warmer regions, and F. crookwellense with cooler regions. Sporadic FHB outbreaks occur principally in the irrigation areas of the country. In favourable years significant damage is caused....

ABSTRACT Fusarium spp. in maize can contaminate the grain with mycotoxins if environmental conditions are favorable for fungal growth. To quantify the relationship between growth of Fusarium spp. and environmental conditions, a mathematical model was developed to simulate growth of F. graminearum and F. verticillioides on maize ears following silk inoculation in field experiments from 1992 to 1...

Antifungal activity of bioactive compound 2H-Furo[2,3-H]-1-benzopyran-2-one isolated from seeds of Psoralea corylifolia L. were tested against eight Fusarium species of maize seeds at 1001000ppm concentration. F. moniliforme, F. oxysporum, F. semitectum and F. solani were completely inhibited at 600ppm concentration. F. equiseti, F. lateritium and F. proliferatum were completely inhibited at 70...

The cereals crops in Belgium are not safe from serious contaminations by mycotoxins. Theyears 1997 and 1998 for example were very favourable to the development of Fusariumhead blight. On that account, the project main objective consists in assessing the risk ofmycotoxins contamination and studying the environmental factors that contribute to increasethe rate of wheat contaminati...

ABSTRACT Fusarium head blight (FHB), or scab, is a destructive disease of small grains caused by members of the Fusarium graminearum species complex, comprised of at least nine distinct, cryptic species. Members of this complex are known to produce mycotoxins including the trichothecenes deoxynivalenol (DON) along with its acetylated derivatives and nivalenol (NIV). In this study, 31 strains, b...

fusarium graminearum is one of the most important causes of fhb or wheat scab in different part of the world. this fungus is able to produce widespread trichothecene mycotoxins such as nivalenol (niv) and deoxynivalenol (don) which are harmful for both human and animals. to determine chemotypes of trichothecene, a total of 100 isolates from different fields of golestan province in iran includin...
