Blueberries (Vaccinium spp.) are widely cultivated worldwide for their high economic and nutritional value. However, fungal diseases constitute a major biotic constraint limiting the development of the blueberry industry. To date, more than 20 fungal diseases have been reported on blueberry, causing substantial economic losses. This review systematically summarizes the pathogen species, geographic distribution, typical symptoms, and damage severity of major fungal diseases affecting blueberry production. The principal diseases discussed include stem blight, canker, root rot, leaf spot, anthracnose, powdery mildew, gray mould, and fruit rot. Previous studies have shown that severe outbreaks of these diseases may result in yield losses ranging from 20% to 85%. Pathogenic fungi associated with blueberry exhibit high diversity, encompassing over 150 species from more than 20 genera, including Diaporthe, Fusarium, Neofusicoccum, Pestalotiopsis, Phytophthora, Colletotrichum, and Alternaria. In addition, the main transmission routes of these pathogens are summarized. Based on current knowledge, integrated disease management strategies are proposed, including cultural practices, chemical control, and biological control. Furthermore, the current shortcomings in research on blueberry fungal diseases are clarified, particularly in aspects of etiology, disease epidemiology, and resistance breeding. Future work should focus on strengthening studies on pathogen biology, epidemic dynamics, breeding of high-yield, high-quality, and disease-resistant cultivars, and promoting green control technologies centered on agricultural and biological measures. Overall, this review provides both strong theoretical support and targeted practical guidance for the healthy development of the blueberry industry in China.
