The effects of finite Larmor radius (FLR), collisions, and Hall currents are investigated on thermosolutal instability of a partially ionized plasma in porous medium in the presence of a uniform vertical magnetic field. In the case of stationary convection, finite Larmor radius, Hall currents, medium permeability and magnetic field may have stabilizing or destabilizing effects but for a certain wave number range, FLR, magnetic field and Hall currents have stabilizing effect only. The stable solute gradient always has a stabilizing effect on the system whereas collisional effects disappear in the case of stationary convection. It is found that the presence of each-magnetic field, FLR, Hall currents and collisions introduces oscillatory modes which were, otherwise, non-existent.\Keywords: Thermosolutal instability, Partially ionized plasma, FLR, Hall currents, Porous medium
