This research primarily describes the role of viticulture in the agricultural structure of Istria County, followed by an analysis of the virus characteristics, its symptoms, and transmission routes. Since one of the objectives of the study is to investigate the awareness of winegrowers regarding virus-related problems, an online survey was conducted with 30 participants. The goal of the survey was to determine participants' current knowledge of viruses, their ability to recognize symptoms, their understanding of virus transmission and control methods, and their personal experiences and opinions. The survey consisted of 30 questions and was conducted online using Google Forms. Survey results indicate that the majority of respondents believe they have adequate knowledge of viruses and their characteristics. Most respondents show relatively good knowledge in questions about the consequences of viral infections, but have difficulty identifying viruses from pictures of symptoms. Respondents showed lack of knowledge in questions related to detection (symptoms, vectors, etc.), but on the other hand, they are well acquainted with virus control methods. Nevertheless, 96.7% of respondents conclude that growers should increase their knowledge about the occurrence, severity and consequences of virus infections, and they consider that the awareness of grape growers in general is very low. Respondents conclude that they are not sufficiently familiar with viruses and that they will become better informed about them after the survey.
