Two types bacteria isolated samples disease, namely E. amylovora, P. syringae, necrosis. results studies species confirmed Swiss scientists Agroscope research center based an immuno-chromatographic test Russian at All-Russian Research Institute Plant Quarantine enzyme-linked immunosorbent assay, FLASH polymerase chain reaction, reaction real-time.
