A comprehensive study was conducted which included sampling from a total of 19 orchards from four different districts. The samples were collected according to the major symptoms of phytoplasma disease which were foliar reddening, witches' brooms, leaf rosettes, yellowing, longer peduncles and development of undersized fruits. It was determined that six out of 62 plant samples were infected with phytoplasma. Also, two out of six infected samples were determined as infected by 'Ca. P. mali' and unexpectedly four out of six infected samples were determined as infected disease. Even if the incidence of the disease (9.7%) was low, the characterized phytoplasmas were considered a significant potential threat for these locations.eninfo:eu-repo/semantics/openAccessPCR-RFLPSurveyNigdeApple proliferation diseaseEuropean stone fruit yellows diseaseArticle2751080108610.18016/ksutarimdoga.vi.14402861265383WOS:001309840400010N/A
