Northern Corn Leaf Blight, incited by the fungal pathogen exserohilum turcicum, poses a significant threat to maize production worldwide, necessitating innovative and sustainable control strategies. In this paper, a mathematical modeling for the control and management of northern corn leaf blight in maize with early chemical application. The model has been analyzed, in the local stability subsection, it has been shown that the disease-free equilibrium is locally asymptotically stable if the basic reproduction number is less than one. The global stability of disease-free equilibrium shows that; the system is globally asymptotically stable is the basic reproduction number is less than one. Further, we assess the global stability of endemic equilibrium point, which showed that the endemic equilibrium point is globally asymptotically stable if the basic reproduction number is greater than one. In numerical simulation section, we were able to assessed the impact of early chemical spray on maize plant and treating the infected maize plant with chemical spray, it has been noticed that, early chemical spray on maize plant is the best way to control the northern corn leaf blight in maize population. It is now recommended that early chemical spray on maize plant is the best way to control the northern corn leaf blight in maize.
