Achievements and prospects in the application of viruses for agricultural biotechnologies and biological plant protection

Against the background of the increase in the impact of climate change and the worsening of the phytosanitary situation caused by the development of harmful organisms, there is an increase in scientific investigations on plant protection, especially biological control with the application of ecologically friendly means. Among the microbiological agents used in the development of biological preparations, a particular position belongs to viruses. As ubiquitous entities, viruses not only infect almost every species, but play a significant role in evolution, facilitating biogeochemical processes and participating as a determining factor in the control of host populations, as well as in the application of viruses for agricultural biotechnologies and biological plant protection. The article contains discussions on the results recorded on the role and place of viruses in the biosphere, the particularities of the application of baculoviruses as biological agents to control the density of pest insect populations, t, the importance of fages in the control of phytopathogenic agents, the possibilities of using mycoviruses in the biological control of phytopathogenic fungi, achievements and perspectives in the application of viruses in the control of phytopathogenic fungi. diseases caused by phytopathogenic viruses
