Transport properties in doped manganites are studied by considering the Simplified double exchange mechanism in the presence of diagonal disorder. It is modeled by a combination the Ising double exchange with Faliccov-Kimball model. In this model, charge order ferromagnetic and transport quantities are presented by using Dynamical mean-field theory in the case of finite Hund coupling and disorder strenght. Those results suggest that, within this model the insulator phase can be stated in the range of below charge order temperature which is suitable with the observations in the experimental manganites.
