“…Infections of standing cereal crops by Aspergillus species and contamination by aflatoxins are mild or very rare under the climatic conditions of many European countries: Austria (Öhlinger et al, 2004), Belgium (Chandelier et al, 2004), Germany (Curtui et al, 2004), Hungary (Varga et al, 2004), Poland (Perkowski et al, 2004), Romania (Ittu et al, 2004), the UK (Scudamore, 2004), etc. In 2003, extremely high temperatures during the whole growing season of maize and extraordinary drought from early May to early September, resulting in high levels of water stress for maize cultivated in Northern Italy, led to an intensive occurrence of A. flavus and aflatoxins contamination of maize crops (Moretti et al, 2004).…”

SUMMARYThe frequency and incidence of A. flavus and A. niger on barley, maize, soybean, sunflower and wheat grain, the abundance of European corn borer (Ostrinia nubilalis) moths and their interaction depending on weather conditions in the 2008-2012 period were studied. Under the agroecological conditions of Serbia, the species A. niger is more frequent than A. flavus, and concerning the crop species, its frequency is highest in kernels of sunflower, than soybean, maize, barley and wheat. A. flavus was extremely dominant on all plant species in 2012 regarding its frequency: 100% on soybean, 95.3% on maize, 65.2% on barley, 57.1% on sunflower and 45.8% on wheat. Furthermore, the incidence of A. flavus was higher in 2012 than in previous years. The uncommonly high frequency and incidence of A. flavus infestation of maize grain in 2012 were caused by extremely stressful agrometeorological conditions, high temperatures and drought over the period from flowering to waxy maturity of maize. The precipitation factor (Pf = precipitation sum / average monthly temperature) showed that 2012 was extremely arid in June (Pf = 0.57), July (Pf = 1.45), August (Pf = 0.15) and September (Pf = 1.42). European corn borer (ECB) was a second factor causing intensive occurrence of A. flavus on maize grain in 2012. The maximum flight of ECB moths was recorded as early as in July (5,149) and, as a result of this, high damage and numerous injuries were detected at harvest. Those injuries were covered by visible olive-green powdery colonies typical of A. flavus. In the chronology of A. flavus occurrence, these are the first data on its very high frequency and incidence under the agroecological conditions of Serbia. As intensive infections with A. flavus were rare in the past 50 years, the level of aflatoxins in maize grain was low.

“…Deoxynivalenol concentrations produced by different Fusarium species worldwide vary from 0.01 up to 160 µg/g (Tomczak et al, 2002;Ittu et al, 2004), while ZEA concentrations vary from 0.004 up to 18 µg/g (Moretti et al, 2002;Varga et al, 2002). In Serbia, DON has been confirmed to vary from 0.25 up to 45.56 µg/g (Stanković et al, 2008) and ZEA from 0.03 up to 12.8 µg/g (Bočarov-Stančić et al, 2000;Stanković et al, 2007).…”

SUmmARyA total of 39 Fusarium graminearum, F. sporotrichioides, F. semitectum and F. equiseti isolates, originating from wheat and maize samples collected at 10 locations in Serbia, were analyzed by ELISA method for their potential of deoxynivalenol (DON) and zearalenone (ZEA) production under optimal laboratory conditions. Fusarium graminearum isolates with the highest intraspecies variability were the best producers of both deoxynivalenol and zearalenone. In contrast, F. equiseti isolates were the weakest producers of these two toxins. Considering the plant origin of the isolates, wheat-originating F. sporotrichioides isolates were better deoxynivalenol producers, while the maize-originating isolates produced more zearalenone. There was no clear difference in ZEA production between wheat-and maizeoriginating isolates of F. graminearum, while higher average DON concentrations were produced by F. graminearum wheat-originating isolates.Negative correlation was detected between the production of deoxynivalenol and zearalenone by various Fusarium spp.

Summary: Species of the genus Aspergillus, section Flavi are facultative plant pathogens with the capability to contaminate primary agricultural products in the field, at harvest, in warehouses, and during processing. Infection is done through silk or injuries on maize ears. The objective of this study was to test pathogenicity of 25 A. parasiticus isolates on barley leaves. A. parasiticus was isolated from maize kernels collected from 22 locations in Serbia during 2013-2015. Inoculation of the first barley leaf was done by the spore suspension of the fungus A. parasiticus. The spot sizes were statistically compared and this comparison showed that the isolate MRIZP 3930 was the least virulent. The isolate MRIZP 3819 was the most virulent seven days after inoculation and together with the isolate MRIZP 4265 was classified into the most aggressive group rated as 5. Pathogenicity was confirmed in all isolates.
