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.

Methodology of testing wheat resistance to brown leaf spot diseases under field conditions
Šíp, Václav ; Chrpová, Jana ; Palicová, Jana ; Hanzalová, Alena ; Čejka, Lubomír
This handbook brings new conclusions and recommendations concerning mainly the field resistance tests - the choice of fungal isolates, design of experiments, inoculum preparation and inoculation technique, as well as evaluation of disease symptoms and tolerance to the disease. Attention was paid to the pathogens Mycosphaerella graminicola anam. Septoria tritici, Pyrenophora tritici – repentis anam. Drechslera tritici-repentis and Phaeosphaeria nodorum anam. Stagonospora nodorum that showed frequent occurrence in the examined territory. The presented findings are based on experience gained from the ring tests of disease resistance performed in the period 2002-2014, available literature and special experiments with Septoria tritici performed within the research project QJ QJ 1210189 This methodology is mainly aimed at increasing precision of tests of resistance to these diseases which will favourably impact on resistance breeding, variety testing, as well as on adequacy of plant protection measures taken in agricultural practice.
