Abstract
The object of the study was mycological analysis of settlement of winter wheat grain samples collected in 2005/2006 and 2006/2007 cropping seasons with the special respect to a new species — Fusarium langsethiae. Its presence was noted in 38 samples in relatively low intensity (from 0.5 up to 3.5%). PCR assay confirmed identity of 38 isolates as F. langsethiae. Mycelium of tested strains of F. langsethiae was whitish with powdery appearance. Microconidia were formed napiform or globose, nonseptate, formed in heads. Macroconidia, sclerotia, and chlamydospores were not present after 3 weeks of incubation. Growth rates ranged from 5.4 to 10.3 mm/day. No isolate had potential ability to type B trichothecenes. Detailed chemical analyses of two strains showed them as producers of T-2 and HT-2 toxins at high concentrations.
