Abstract： In this paper, the plant disease model including impulsive cultural con-trol strategy (such as roguing and replanting interventions) and Economic Threshold (ET) on the infected plants is analyzed. We examine the existence of the unique pos-itive periodic solution in terms of three cases of a certain parameter space. Then the stability of the periodic solution in three situations is investigated. By using qualitative methods, we prove that the periodic solution in one situation is globally asymptotically stable under some conditions, and the one in other cases is unstable. The main results obtained here extend and generalize the classical results for systems of plant diseases inthe integrated disease management.
