Crop diseases pose a substantial threat to global food security, affecting crop yield, quality and economic sustainability. Conventional disease management methods heavily reliant on chemical interventions have raised environmental concerns and led to the emergence of resistant strains. In contrast, nutrient management emerges as a crucial factor in promoting plant health and bolstering disease resistance. This holistic approach involves optimizing the equilibrium of essential nutrients within both soil and plant tissues to augment the inherent defense mechanisms of plants. The intricate interplay among nutrients, plant physiology and disease dynamics present a complex yet promising avenue for sustainable agricultural practices. Examining key nutrients essential for plant immunity such as nitrogen, phosphorus, potassium and micronutrients reveals how deficiencies or imbalances in these elements can compromise a plant's ability to fend off diseases. Explores the correlation between soil health, nutrient availability and disease prevalence. It emphasizes the need to reconsider traditional practices and advocates for innovative nutrient management strategies to protect crops from diseases. By advocating for a balance between nutritional requirements and natural plant defense mechanisms, this approach holds significant potential for promoting sustainable agriculture and ensuring global food security amid the continually evolving challenges posed by crop diseases.
