Abstract: In this paper, the basic reproduction number is calculated for Huanglongbing(HLB) model with impulses which is a vector-borne epidemic model with impulses.For controlling HLB, farmers’ experience is replanting of healthy plants andremoving infected plants. To reflect the real world, we construct an impulsivecontrol model which considers replanting of healthy plants and removing infected plants at one fixedtime. By analyzing the model, we conclude that the disease-free equilibrium is globally asymptotically stable if the basic reproduction number Ro 1, and we prove that the HLB is permanence if the basic reproduction number Ro > 1.
