<p>Plant diseases cause over 26% of crop losses worldwide, negatively impacting both the quality and yield of agricultural production. Effective management strategies for fungal plant diseases include using resistant cultivars, altering cultural practices, applying bio-control agents and fungicides, alongside integrated disease management (IDM) practices. Among these disease management practices, fungicides have served as a cornerstone of plant disease management due to their efficacy in managing many destructive phytopathogenic fungi and safeguarding food production. However, their widespread and often injudicious use has raised serious concerns about environmental sustainability. Emerging evidence indicates that fungicides can adversely affect non-target organisms, including beneficial soil and phyllosphere microorganisms, pollinators, aquatic biota, and other components of agro-ecosystems. In addition, fungicide residues may accumulate in water and soil, change microbial community function and structure, contribute to biodiversity loss, and promote the emergence of fungicide-resistant pathogens. These unintentional consequences challenge the sustainability of chemical-dependent disease management practices and necessitate the development of eco-friendly and collective tactics. This review examines the injurious impacts of fungicides, with particular emphasis on their non-target effects, environmental fate, ecological risks, and implications for human and ecosystem health. Furthermore, it highlights recent advances in, resistance management, and the development of environmentally benign fungicides as sustainable alternatives. As a result, there is a notable shift from reliance on synthetic chemical pesticides towards adopting integrated disease management practices which ensure food security and eco-friendly agriculture. The review underscores the importance of balancing and effective disease control with environmental stewardship to support resilient and ecological agricultural systems.</p>
