Slavíková, Lucie ; Chrpová, Jana ; Palicová, Jana ; Hanzalová, Alena ; Dumalasová, Veronika ; Ripl, Jan ; Jarošová, Jana ; Kumar, Jiban
The fungal and virus diseases are still very actual topics due to the high proportion of cereals in crop rotation and large cultivated area. The cereal crops often decimated by fungal diseases like eyespot, powdery mildew, smuts, rusts, Fusarium head blight and brown leaf spot diseases. The virus diseases include Barley yellow dwarf virus – BYDV, Wheat dwarf virus – WDV and Wheat streak mosaic virus – WSMV are also very important due to the epidemic incidence in some years. This methodology summarizes the current knowledge of these fungal and virus diseases, focuses on the description, symptoms, occurrence, field and laboratory diagnostics and possibilities of crop protection against these diseases. Individual diseases are ranked in the order of their occurrence in the agroecosystem. The methodology can serve the farming communities and agronomist as a key to identifying the diseases infecting wheat crop.

Methods of detection of wheat and barley strain of Wheat dwarf virus in vector Psammotettix alienus by PCR-RFLP
Jaňourová, Blanka ; Ripl, Jan ; Kumar, Jiban
Wheat dwarf (causal agent Wheat Dwarf Virus - WDV) is one of the most important cereal diseases in the Czech republic where it can cause huge economic losses in wheat, barley, triticale, rye as well as in oat. Psammotettix alienus is the only known vector of WDV while another way of transmission is unrecognized. This methodology describes a PCR assay for sensitive detection of Wheat Dwarf Virus in Psammotettix alienus, and RFLP assay for barley and wheat strains specific identification.
