In this work, we investigate the production of $X_b$ in the process$\Upsilon(5S,6S)\to \gamma X_b$, where $X_b$ is assumed to be the counterpartof $X(3872)$ in the bottomonium sector as a $B {\bar B}^*$ molecular state. Weuse the effective Lagrangian based on the heavy quark symmetry to explore therescattering mechanism and calculate their production ratios. Our results haveshown that the production ratios for the $\Upsilon(5S,6S) \to \gamma X_b$ areorders of $10^{-5}$ with reasonable cutoff parameter range $\alpha \simeq 2\sim3$. The sizeable production ratios may be accessible at the future experimentslike forthcoming BelleII, which will provide important clues to the innerstructures of the exotic state $X_b$.
