“…The emphasis on balanced nutrition as the first line of defence against diseases in crops stresses the significance of providing plants with the necessary nutrients to increase their natural defences. It is a preventive measure that supports plant health, resilience, and sustainable crop management strategies [16,51]. According to Tadayon and Sadeghi [36], balanced nutrition management could reduce the severity of citrus decline in Valencia orange orchards by increasing the leaf concentrations of Ca, B, S and Mg as higher concentrations of these nutrients were positively correlated with a lower citrus decline severity index.…”

“…Overall, information on the nutrient-disease interaction is important owing to the various roles of nutrients in disease management, including forming robust cell walls, generating natural defense compounds like phytoalexins and antioxidants, fostering flavonoid production, and activating enzymes involved in phenol and lignin synthesis [16,51,59]. N stands as a vital element for mango trees, crucial in improving vigor, promoting vegetative growth, and supporting physiological development.…”

Mango twig-tip dieback (MTTD) is a new type of mango decline, but its impact on the trees’ mineral nutrition is unknown. This study was conducted to determine the effect of MTTD infection on the nutrient status, balance, and resorption efficiency (RE) of mango. Leaf nutrient concentrations and deviation from the optimum percentage (DOP) indices of ‘Kensington Pride’ (KP) mango trees with low (LD) and high (HD) levels of MTTD infections were analyzed to compare the foliar nutrition status and nutrient balance between the LD and HD trees. Moreover, the nutrient resorption efficiency of MTTD-infected dried leaves (RED) was compared with the resorption efficiency of healthy (RES) leaves of KP mangoes. The concentrations of Ca, Mg, Cu, Fe, Mn, and Zn were lower in the HD trees than in the LD trees. But the K content was higher in the HD trees, and its DOP index was sufficient, while the K concentration was low and deficient level in LD trees. Moreover, DOP indices for Ca, Mn, and Zn were less deficient in LD trees than in HD trees, and overall nutrient imbalances were exacerbated in HD trees. RED was significantly lower than RES for N, P, S, Cu, Fe, and Zn but significantly higher than RES for K. The study underscores the significant influence of MTTD on the mineral nutrition of KP mangoes, revealing distinct nutrient variations between trees with low and high MTTD infection levels. These findings have important implications for mango crop management, emphasizing the need for targeted nutrient interventions to address imbalances induced by MTTD and enhance the overall health and resistance of mango trees against MTTD infection.

Mineral nutrition is essential for plant growth and interaction of plants with biotic and abiotic stresses. Mango twig-tip dieback (MTTD) is a new type of mango decline, but its impact on the trees’ mineral nutrition is unknown. This study was conducted to determine the effect of MTTD infection on the nutrient status, balance, and resorption efficiency (RE) of mango. Leaf nutrient concentrations and deviation from the optimum percentage (DOP) indices of ‘Kensington Pride’ (KP) mango trees with low (LD) and high (HD) levels of MTTD infections were analyzed to compare the foliar nutrition status and nutrient balance between the LD and HD trees. Moreover, the nutrient resorption efficiency of MTTD-infected dried leaves (RED) was compared with the resorption efficiency of healthy (RES) leaves of KP mangoes. The concentrations of the total Ca, Mg, Cu, Fe, Mn, and Zn were lower in the HD trees than in the LD trees. But the total K content was higher in the HD trees, and its DOP index was sufficient, while the total K concentration was low and deficient level in LD trees. Moreover, DOP indices for total Ca, Mn, and Zn were less deficient in LD trees than in HD trees, and overall nutrient imbalances were exacerbated in HD trees. RED was significantly lower than RES for the total N, P, S, Cu, Fe, and Zn but significantly higher than RES for K. The study underscores the significant influence of MTTD on the mineral nutrition of KP mangoes, revealing distinct nutrient variations between trees with low and high MTTD infection levels. These findings have important implications for mango crop management, emphasizing the need for targeted nutrient interventions to address imbalances induced by MTTD and enhance the overall health and resistance of mango trees against MTTD infection.
