Abstract

The main goal of the research is to study the resistance of widely used pine species in the landscaping of the Absheron Peninsula to serious dangerous pests, to select relatively resistant species, and to recommend them for landscaping farms. At the initial stage of scientific research, phytosanitary monitoring of various types of pine trees cultivated on the peninsula was carried out, dangerous organisms were studied, analyzed, and identified (2020-2023). As a result of the research, it was established that dangerous microorganisms that are often found in economically important pine species in the studied region: pine bark beetle, sub-bark pine bug, pine scale insect, and the causative agent of tar cancer, cause serious damage to the lifestyle and productivity of plants. This is explained by the fact that harmful organisms cannot cause serious harm to the plant due to the activation of protective and regenerative processes inside the plants. Thus, taking into account the resistance of P. eldarica to other unfavourable soil and climatic factors of the peninsula, including the mentioned dangerous pathogenic and harmful insects, in comparison with other species, it is advisable to widely use it as the dominant species in the region’s landscaping.
