“…Variations also exist among host plants: the disease is more severe after maize or durum wheat than after wheat or barley due to the quantities of residues produced and to their chemical composition. Schaafsma et al (2005) found the number of viable propagules trapped at anthesis in wheat fields planted on maize or wheat stubble higher than the number of viable propagules in wheat fields following non-host crops, and the highest number of propagules was found after maize.…”

“…Long-term experience with the disease in a certain growing region, respectful of other risk factors, particularly those influencing the number of viable airborne propagules of Fusarium pathogens at flowering stage (Schaafsma et al 2005), and weather forecasts for critical periods may enable to make the prognosis of disease development, decisive for the choice of control measures. Using important weather variables, a weather-based model to predict the concentration of DON in grain at heading was developed by Hooker et al (2002).…”

Abstract:Reactions to artificial infection with Fusarium culmorum and (metconazole-or tebuconazole-based) fungicides were studied in nine winter wheat cultivars that were evaluated in field experiments at the location Prague-Ruzyně for four years (2001)(2002)(2003)(2004) for deoxynivalenol (DON) content in grain, pathogen DNA content (Ct) by real-time quantitative PCR, percentage of Fusarium damaged grains (FDG), symptom scores and reductions in grain yield components. All examined traits were highly affected by conditions of experimental years and interactions with cultivars and treatments. Moderately resistant cultivars Arina and Petrus were included in the first homogeneous group in all traits, including the pathogen DNA content. To predict cultivar resistance to Fusarium head blight and accumulation of DON, the examination of the percentage of FDG in different environments appeared to be useful from practical aspects. The pathogen DNA content was significantly related to the content of DON under different conditions, however, the correlation coefficients ranged between 0.42 and 0.92. Different levels of DON could be detected at similar pathogen contents. The higher colonization of grain by the fungus was mostly connected with a strongly reduced amount of DON per pathogen unit (DON/Ct ratio). The fungicide treatment had a significant effect on a reduction in all traits except DON/Ct, but the effects on different traits were not often proportional and they were highly variable in the particular years (range 10-69%) and cultivars (range < 0-60%). While the application of fungicide caused a reduction in DON content in all cultivars, an increase in pathogen content after the application of fungicides was not exceptional. The low fungicide effect on a reduction in pathogen content was connected with higher temperatures (temperature extremes) in a 30-day period of disease development. The efficacy of fungicide treatment for DON was low at high pathogen content and late heading. The use of the collected data to improve control measures is discussed.

“…Apart from cereals, F. graminearum frequently infects cobs and stalks of maize (Zea mays L.) and after harvest, infected maize residues are a source of fungal inoculum that can infect a subsequent cereal crop in the rotation. In order to address this question, various investigations have been carried out in the last decade to assess and to quantify the effect of tillage or maize residue management on infection by F. graminearum and DON contamination in wheat (Bateman et al 2007;Dill-Macky and Jones 2000;Oldenburg et al 2007;Schaafsma et al 2005;Steinkellner and Langer 2004;Yi et al 2001Yi et al , 2002. These studies, conducted in Europe and North-America, all demonstrated that, compared with conventional tillage, reduced or zero tillage after maize resulted in greater numbers of airborne propagules of G. zeae/F.…”

On-farm experiments over 5 years in a grain maize/winter wheat rotation: effect of maize residue treatments on Fusarium graminearum infection and deoxynivalenol contamination in wheat

Over the course of 5 years, different maize residue treatments were conducted on 14 zero tillage on-farm sites in Switzerland to evaluate their effect on the development of Fusarium head blight (FHB) and the contamination with the mycotoxin deoxynivalenol (DON) in winter wheat grains and wheat straw following grain maize. Two experimental series with three and five different treatments were carried out, respectively. Fusarium graminearum (Schwabe) was the predominant FHB-causing species with an overall incidence of 15% infected wheat grains. A significant correlation between symptoms in the field, F. graminearum incidence and DON content in wheat grains and wheat straw was observed. The average DON content in both wheat grains and wheat straw was approximately 5,000 μg/kg and thus several times higher than the European maximum limit of 1,250 μg/kg for unprocessed small-grain cereals for human consumption. Of all grain samples, 74% were above the maximum limit. Pooled over both experimental series, the average reduction of DON in grains through treatments of the maize residue compared with a control treatment ranged between 21 and 38%. The effect of various other factors, including the year, the wheat variety, the site, the maize hybrid and the production system was evaluated as well. The year and the wheat variety were the most important FHB influencing factors. Over all treatments, the variety Levis showed a fivefold higher average DON content compared with the variety Titlis. From different categories of maize residue particles, intact pieces of 5-15 cm length were strongly correlated with F. graminearum incidence and DON content in grains. During the time course of this study, the recommendation from a preliminary version of the internet-based DON forecasting system FusaProg to apply or to omit a fungicide treatment was correct in 32 out of 42 cases. The results are currently being used to optimise the FusaProg models. This study has shown that in a grain maize/winter wheat rotation, the DON content in wheat grains frequently exceeded the European maximum limit, even with a thorough treatment of maize residues and less susceptible wheat varieties. Hence, in order to reduce the contamination risk in a zero tillage system, the crop rotation needs to be modified.
