Abstract

The global asymptotic stability is considered in the model of rice blast disease under the difference of rice cultivar susceptibility, virulence of fungus and growth stage of rice. A new global as-ymptotic stability criterion of equilibrium point for susceptible-exposed-infections-recovered (SEIR) epidemic model is derived by constructing a suitable function. Then, this research shows the points of free-disease equilibrium and endemic equilibrium to be able to apply for study on the preparation to prevent the rice blast disease or plan rice planting.
