In models with an enhanced coupling of the Higgs boson to the bottom quark, the dominant production mechanism in hadronic collisions is often the partonic subprocess, $bg\to bH$. We derive the weak corrections to this process and show that they can be accurately approximated by an “improved Born approximation.” At the Tevatron, these corrections are negligible and are dwarfed by PDF and scale uncertainties for $M_H<200\mathrm{GeV}$. At the LHC, the weak corrections are small for $M_H<500\mathrm{GeV}$. For large Higgs boson masses, the corrections become significant and are $\sim 18\%$ for $M_H\sim 1\mathrm{TeV}$ at $\sqrt{s}=10\mathrm{TeV}$.
