Monitoring studies of the occurrence of fire blight pathogen in Kazakhstan and identification of antagonistic microorganisms suppressing its development.

The paper presents data on phytosanitary monitoring of garden cenoses for fire blight in the Turkestan, Zhambyl, and Almaty regions of Kazakhstan. The purpose of this study is to assess the phytosanitary situation in various regions of Kazakhstan, determine the extent of fire blight spread, and isolate and identify the fire blight pathogen. During the study, methods such as hypersensitivity, pathogenicity, and fluorescent simplification-based specific hybridization polymerase chain reaction (FLASH-PCR) were used.
