Management Strategies of Grey Mould Disease in Berries

Abstract Grey mould, caused by the necrotrophic fungus Botrytis cinerea , represents a significant threat to berry crops worldwide, particularly impacting strawberries and raspberries and resulting in substantial economic losses annually. This pathogen thrives in cool, humid environments, initiating infections on various plant parts, including leaves, flowers, and fruits, ultimately leading to fruit rot and quality degradation. Botrytis cinerea possesses a complex disease cycle, overwintering as sclerotia or mycelia and producing abundant conidia that spread via wind and water. Infection can occur through direct penetration or via wounds, with symptoms ranging from leaf lesions to blossom blight and fruit rot. The fungus’s ability to adapt and develop resistance to commonly used chemical fungicides poses a major challenge to effective disease management. This case study reviews the biology, disease cycle, and symptoms of grey mould in berries. It comprehensively examines current management strategies, including cultural practices such as optimizing air circulation and sanitation, chemical controls with various modes of action, and the increasing importance of biological control agents and biotechnological approaches. Additionally, this case study highlights the challenges associated with fungicide resistance and emphasizes the need for sustainable and integrated disease management strategies to minimize economic losses and ensure high-quality berry production. Future research directions focus on innovative solutions, including developing resistant cultivars and improving the efficacy and application of biocontrol methods. Information © The Authors 2025
