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...

Fusarium head blight (FHB) is among the major causes of reduced quality in winter wheat and its products. In addition, the causal fungi produce a variety of toxins. A relatively high FHB infection rate in winter wheat was observed in 2007 and 2008 in Luxembourg. A fusariotoxin survey was carried out in 17 different geographical locations. Three groups of Fusarium mycotoxins (trichothecenes A an...

Search for the preventive measures reducing the accumulation of mycotoxin producers in food raw material was carried out. Active ventilation was used; the impact of the electro-chemically activated air (ozone) and electro-chemically activated water (anolyte) on the micromycetes prevailing in grain raw material for food (GRMF) was determined. The GRMF was dried by active ventilation using the oz...

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...

Nine cultivars of winter wheat were compared in organic and conventional crop rotation systems. Bread-making quality was evaluated using three parameters [thousand-kernel weight (TKW) in g, volume weight in g/l, protein content in %]. Grain yield, TKW and protein content of winter wheat in organic cropping system were significantly lower as compared to any intensity in conventional cropping sys...

The interactive effects of asexual Epichloë (formerly known as Neotyphodium) endophytes isolated from Hordeum brevisubulatum, Elymus tangutorum and Achnatherum inebrians, and seed-borne fungi on Elymus sibiricus seeds, were determined by an in vitro study using supernatants from liquid cultures of the endophyte strains. In an 8 week greenhouse study, the effects on the seedlings growth was meas...

Aim. To investigate the field resistance of collection spelt-like samples Chornobyl radio-mutants (RM) winter wheat to Fusarium head blight and determine species composition fungi genus in Forest-Steppe Ukraine. Methods. The (in scores) ten RM-samples Fusar- ium was determined conditions by visual inspection plants using standard methods (Trybel et al, 2010). infection rate seeds, biological me...

In today's environment, an important task of agricultural production is to increase yields and improve the quality products. A reliable environmentally beneficial factor for sustainable yield improvement grain development new varieties with group resistance diseases a high level adaptability. The effectiveness selection immunity directly depends on diversity donor genes, search sources has been...
