“…Malting wheat samples showed somewhat different picture for control and inoculated treatment, where in the control and inoculated treatment, only 4 of the 25 samples had less 3-ADON after malting. Our results are not in accordance with Váňová et al (2004) [ 28 ], who revealed that DON was not detected in barley malt in the non-treated control, but DON concentration depended on the specific climate of the testing year and position of the test field. According to Schwarz et al (1995, 1997) [ 32 , 33 ], production of mycotoxins during malting is difficult to predict from the original barley, and is probably dependent upon viability, as well as the original level of infection.…”

“…This was also concluded by Schwarz et al (2006) [ 27 ] for barley samples; however, due to large amount of unexplained variation, they concluded that this relationship needs to be further investigated in details. The same was noticed by Váňová et al (2004) [ 28 ], who revealed that content of DON increased in most cases after the barley samples were malted. Moreover, Schapira et al (1989) [ 29 ] concluded that T-2 toxin, DAS and DON had the potential to affect malting and malt characteristics, with the possibility that even at the much lower natural levels in grains, these mycotoxins acting additively or synergistically with others may have a deleterious effect on malting.…”

Fusarium head blight is a destructive disease of cereals worldwide. The aim of this research was to study the effect of heavy Fusarium infection with Fusarium culmorum and biosynthesis of mycotoxins on different wheat varieties during malting by setting up field trials with control and Fusarium-inoculated treatments at the Agricultural Institute Osijek. The highest occurrence of Fusarium mycotoxins was expectedly recorded in susceptible variety in grain and malt (3247 and 1484 µg kg−1 for deoxynivalenol (DON), 735 and 1116 µg kg−1 for 3-acetyl deoxynivalenol (3-ADON), 37 and 233 µg kg−1 for zearalenone (ZEN), respectively). Based on published information, complemented by our own results, the following conclusions can be drawn: The presence of 3-ADON in different wheat varieties might be the result of its conversion into DON by deacetylation during the malting process. The detection of the mycotoxin ZEN indicated that this mycotoxin is only specific for wheat malt.

“…Contamination of commodities by Fusarium spp. affects the competitiveness of barley production on both domestic and export markets (Váňová et al 2004). The soil samples taken from the topsoil horizon (0-30 cm) were analysed for P and K content using the method Mehlich III, N by analyser FP-528 (LECO), pH/KCl by electrometric method Sugar beet, maize, winter wheat and oilseed rape were the previous crops.…”

211Successful growing of spring barley for malting purposes depends on many factors. The yield and its stability as well as grain quality are of great importance to growers. A critical role is ascribed to the previous crop and besides, time and method of its harvest, soil tillage and the method used to manage organic matter from the preceding harvest. These factors affect nutrient content in the soil environment, availability to the root system of spring barley, physical properties of the soil and health status of the crop stand. Here, an important role is played by the variety and its genetically determined resistance to diseases, a course of weather conditions during the year and relevant occurrence of diseases.There are very good conditions for growing spring barley for malting in several regions in the Czech Republic. In the past, cultivation of barley in these regions was based on good crop rotations, where high quality of malting varieties was given by quality of the previous crop. The previous crops, which are mostly used now, were considered less favourable (oilseed rape) and barley was not grown after them at all. Farmers, being under economical pressure, grow barley even after summer intercrops. Furthermore, the barley management practice using the traditional previous crop sugar beet is not the same either, since beet tops are not harvested and producers have reduced a tillage system. Such a tillage system is very often used in the case of other commodities in rotation with barley including wheat, poppy, maize, and oilseed rape. , annual precipitation sum 599 mm) in a five-course crop rotation, where spring barley followed the previous crops sugar beet, winter wheat, maize, and oilseed rape. The experimental years differed a lot in temperature and precipitation. The years 2001 and 2002 were dry and warm and grain yield was much lower as compared to that in the following years even though the other growing conditions were identical. The most stable quality parameters were obtained after the previous crop sugar beet. The average value of test weight was 661 g/l (ranging from 629 to 685 g/l), protein content 11.2% (10.3-11.7%) and starch content 61.5% (58.9-64.9%). Grain yield averaged 6.67 t/ha. Test weight after maize was on average 658 g/l (619-692 g/l), protein content 11.5% (10.1-12.4%), starch content 60.7% (59.2-63.8%), and grain yield 6.24 t/ha. Test weight and starch content were lower and protein content higher after oilseed rape and winter wheat. A higher FHB incidence and DON content were found after the previous crop maize. In 2001 and 2002 with strong water deficit during the growing seasons, more grains infected by Fusarium spp. were detected and DON content was higher too. The increase was due to a short rainy period at heading of spring barley. Problems of variable conditions for growing malting varieties of spring barley and current possibilities of producing both good grain yields and quality are discussed.

“…The efficiency of fungicides in decreasing mycotoxin HT2 and T2 in barley grain was not demonstrated. Similarly, the field trials conducted in the Czech Republic over four years with spring barley revealed, that the mycotoxin content in kernels varied between the years, but the combination of the active fungicide ingredients decreased the accumulation of DON (Váňova et al, 2004). In France, it was also found that in naturally infected conditions in winter barley during three experimental years the average DON content was very low (<20 µg kg -1 ) and the fungicide treatment had an indistinct effect on Fusarium infection (Ioos et al, 2005).…”

Fungicides are widely used to reduce Fusarium infections and grain contamination by mycotoxins and increase the yield in cereals, but the efficacy of fungicide treatments in varying climates has not been systematically explored. Field experiments with Estonian spring barley (Hordeum vulgare L.) cv. ‘Maali’ were carried out in three successive years 2012–2014 with strongly varying weather conditions to study the effects of three fungicides, Folicur (active ingredient tebuconazole), Falcon Forte (prothioconazole, tebuconazole, spiroxamine) and Archer Top (fenpropidin, propiconazole), on the yield, incidence of Fusarium spp. and on the contamination of grain with mycotoxins DON, HT-2 and T-2. The fungicides were sprayed once a year at spring barley flowering time. The weather conditions during the three years of study were extremely different. The content of cycotoxin DON, HT2 and T2 was low. The spraying with fungicides had not a clear effect on the barley yield and 1 000 kernel weight, and the study year was primarily the main factor that affected barley yield (p<0.05) and 1 000 kernel weight (p<0.05). The impact of year together with fungicide treatment had a significant effect on the incidence of Fusarium spp. (p<0.05) and on the incidence of mycotoxin DON in barley kernels (p<0.001), but did not have a clear effect on the incidence of mycotoxins HT2 and T2.
