Strategie minimalizace výskytu patogenů v klasech pšenice
Jurčík, Milan
The proposed work aims to describe the agents causing diseases of winter wheat, and their elimination strategies. The initial part is dedicated to the significance, division, traditional and less traditional types of utilization growing, and wheat characteristics. This part is followed by information on production and growing areas in the Czech Republic during the last decade. Furthermore, the significance of the genetic factor for the yield formation process of wheat is described and so are the key grain quality parameters. Resistance of wheat varieties to pathogens based on genetic resistances as well as resistance-promoting passive mechanisms (type of flowering, spike density and plant height) is mentioned. Moreover, agrotechnical measures ensuring elimination of pathogens occurrence in stands (seed quality, forecrop, soil processing, sowing time and depth, nutrition and health condition, choice of fungicide and the time and method of its application) are specified. The majority of the paper focuses on diseases that damage wheat spike and the causing agents of these diseases, including proposed strategies of their elimination in stands.
