A control model is developed based on three control measures; the prevention measure (u</em><em><sub>1</sub></em><em>) that protect susceptible crops from pest (the rate of brush trimming and removal of weeds), pesticide control measure (u</em><em><sub>2</sub></em><em>) and the rate of removal of infected plants (u</em><em><sub>3</sub></em><em>). The effective reproduction number that determines pest extinction and crop survival is obtained and use to establish the condition for the local asymptotic stability of the pest-free equilibrium using the method of linearization. The existence of the pest- endemic equilibrium is verified using the Descartes rule of signs. Numerical simulations are performed </em><em>to reveal the effects of the control measures on the field crops. </em><em>The findings show that each integrated measure is able to mitigate pest infestation in the specified time.</em></p>2026-08-31T00:00:00+00:00##submission.copyrightStatement##
