A mathematical model of a grove infected by citrus greening is established, in which
an impulsive control strategy of removing infected trees and dead trees is adopted and the general
incidence is taken into consideration. By the method of fluctuation, the dynamics behavior is
analyzed. Theoretical results show that if R1 < 1 the disease-free periodic solution is global
attractive and the disease becomes extinct, if R2 > 1, the disease-free periodic solution is unstable
and the disease uniformly persists. By numerical simulation, the theoretical results are illustrated
and sensitivity analysis is given.
