Ait.) cultivation since its emergence in the late 19th century. This study reviews the epidemiology, historical management strategies, and recent resurgence of CFBD, with a focus on its causal phytoplasma pathogen and insect vector, the blunt-nosed leafhopper (BNLH), and the implications for disease control. Initial outbreaks in Wisconsin were characterized by floral phyllody and abnormal shoot development, and early misattribution of the disease to abiotic factors delayed effective interventions. The identification of BNLH as the primary vector catalyzed the development of integrated management strategies, including vector control through insecticides, flooding, and sanding, as well as the establishment of certification programs to restrict the spread of infected propagation material. Early cranberry breeding programs identified landraces with lower CFBD field incidence, and which were nonpreferred for feeding by BNLH, leading to the first generation of improved cranberry cultivars. Despite successful suppression after 1950, CFBD has reemerged since 2010, correlating with shifts in integrated pest management practices and the adoption of high-yielding cranberry cultivars lacking resistance screening. The resurgence underscores the need for renewed focus on vector monitoring, the development of resistant cultivars, and an understanding of phytoplasma-vector-host interactions. Contemporary management requires interdisciplinary collaboration, incorporating advances in molecular diagnostics, eco-epidemiological modeling, and breeding programs prioritizing CFBD resistance. The historical insights into CFBD control, combined with modern scientific approaches, provide a framework for mitigating current and future outbreaks, ensuring the sustainable production of cranberries in North America and beyond.
