Výskyt patogenů v porostu lilku bramboru
 Novák, Ondřej
This bachelor thesis is focused on the occurrence of pathogens in the potato (Solanum tuberosum L.) crop. The objectives of the thesis were to describe potato, to describe the pathogens that attack potato and, in the practical part, to observe and evaluate the occurrence of late blight, early blight (on chemically treated and untreated parts of the plot) and Y – virus of potato. In each section, pathogen incidence was monitored on 15 varieties. Late blight occurred only minimally in the crop. This was due to the dry and warm weather during the growing season, which caused minimal spread of the disease. On the other hand, early blight occurred on all varieties surveyed. This disease usually appears in the crops during the warm and intermittently wet season. Y-virus of potato was significantly present on one third of the varieties surveyed. The occurrence was caused by a record infestation of the peach aphid, which transmits the PVY virus.
