Abstract: The purpose of this study was to investigate the effectiveness of a bioorganic composition for the protection of pine plantations, to assess its effects on the growth, development, and resistance of trees to pests and diseases. The methodology included field and laboratory studies, during which various concentrations of the bioorganic composition were used to treat seedlings and young pine trees. The findings revealed that the use of the bioorganic composition increased the height, trunk diameter, and number of new shoots of pine trees. It also reduced the infection with diseases such as pine blister rust, fusariosis, and white pine blister rust, while the number of pests decreased by 80-85%.
