“…Early -1st decade of the month, mid -2nd decade, late -3rd decade. Earlier and later dates of sowing were disregarded due to the low number of samples These results may explain the higher number of detections of F. graminearum observed lately on wheat kernels in Poland, Netherlands and Austria (Stępień et al 2008;Weber and Kita 2010;Mielniczuk et al 2012). F. graminearum is one of the most aggressive species in comparison to other fungi of the genus Fusarium and for this reason, a common prevalence of this species on stem bases of winter wheat in Poland should be taken seriously.…”

“…The selected species of F. graminearum, F .culmorum, F. poae and F. sporotrichioides are the prevalent causal agents of Fusarium diseases of roots and stem bases of wheat in Poland (Baturo 2006;Łukanowski 2009;Mielniczuk et al 2012). We have determined their relationships with the following important factors: geographic region, previous crop, herbicide application, date of sowing and rate of autumn nitrogen fertilization.…”

Foot rot and crown rot are fungal diseases of wheat caused by a complex of Fusarium species. They have a huge economic impact mainly due to yield reduction. A survey was conducted to identify four Fusarium species, occurring on wheat stem bases, using speciesspecific PCR assays in samples collected during spring of 2012. The dominant species was F. graminearum, which was identified in above 64 % of samples. F. culmorum was detected in 15.71 %, F. poae in 15.71 % and F. sporotrichioides in 5.71 % wheat fields. Most of the wheat fields in the eastern Poland were infected with at least one or two of Fusarium species, while in central Poland no Fusarium species were identified in most of the fields. The presence of F. graminearum tends to favor the presence of F. culmorum and this effect was visible also for F. poae and F. sporotrichioides. The frequency of F. graminearum and F. culmorum detections were highest where wheat crops were preceded by maize and in the samples from late sown fields. The opposite observation was made for F. poae and F. sporotrichioides, where the number of detections of these species was higher in samples from early sown fields. The number of detected Fusarium species was significantly lower in samples collected from fields protected with autumn herbicide in comparison to unprotected fields. The rate of autumn N fertilization did not affect the number of Fusarium detections.
