Alternaria solani is one of the most notorious fungal pathogens that causes the destructive early blight (EB) disease of tomato (Solanum lycopersicum L.). Direct application of pesticide is a perilous approach to control disease due to its residual effects, therefore manipulating crop nutrition is a holistic approach to mitigate EB disease by improving the resilience in plants against disease in the sustainable cropping system. Achieving this aim, the effects of plant nutrients viz., nitrogen, phosphorus, potassium (NPK), zinc (Zn), magnesium (Mg) and boron (B) were investigated in controlling early blight disease of tomato. Pathogen infestation camouflaged cell mechanism and disturbed the regulation of key player enzymes (SOD, CAT, POX, PPO and PAL) that weakened the plant immunity, therefore, the plants exhibited 100% disease incidence. Applied nutrients reduced the EB disease by effective interference …
