A new formulation of renormalized theory for fluid-type turbulence to obtainwavenumber spectrum and turbulent diffusivity is presented. An application to theresistive interchange mode turbulence is discussed. The turbulent diffusivity using thereduced MHD equations agrees with evaluations based on the mixing length argu-ment or the scale invariance except a coefficient of about four. An extended modelbased on finite Larmor radius magnetohydrodynamics (FLR-MHD) including coupl-ing between the resistive drift wave and the resistive interchange mode is analyzed bythe renormalized theory. The diffusivity depends on the phase difference and the relafive magnitude between the density fluctuation and the potential fluctuation, and roleof density gradient becomes more significant than the reduced MHD result. However,the wavenumber spectrum does not change much by the extended model.
