Viral diseases pose a serious threat to crop productivity, as they affect a wide range of crops: from vegetable and ornamental species to fungi. Unlike fungal or bacterial infections, viruses deeply affect the physiological processes of plants, causing irreversible developmental disorders, a decrease in yield, and deterioration of produce quality. For an agronomist and a specialist in protected ground, it is critically important to understand the mechanisms of pathogen transmission via pests, seeds, and soil in order to timely prevent the emergence of infection foci.
This collection brings together materials dedicated to the diagnostics, prevention, and control methods for viral infections in greenhouse and open-field conditions. Readers will find detailed descriptions of symptoms of common diseases, such as cucumber mosaic or TMV lesions in peppers, as well as an analysis of factors contributing to the development of epiphytotics. Special attention is paid to integrated plant protection systems, including sanitary measures, disinfection, and modern biotechnological approaches to restoring the health of plantings. Studying the presented articles will help to systematize knowledge about viral biology and build an effective strategy for protecting agroecosystems from hidden threats.
