The theoretical part of this thesis describes three different types of vinegrape productions in the Czech Republic – the integrated system, organic production and biodynamic way of vinegrape production. It describes the resistence and its mechanisms in the vine. A substantial part of the paper is focused on the fungal disease protection in organic grapevine production and finally the topic of elicitor-based preparations is discussed. The experimental part of the thesis concerns the comparison of three systems of protection against fungal diseases applied on grapevine. The Influence of these applications on the fungal disease infection and grape quality is monitored. From the results it is clear, that effectiveness of the three variants has been very similar and none of them was extremely distinctive either positively or negatively. As the most efficient variant was considered to be the EKO one, the author therefore recommends the application of the anti-fungal-disease preparations used in an ecological regime with the elicitor-based preparations included.
