Abstract: We study commutators of Berezin transforms $\mathcal B_α$ associated with radial weighted Fock spaces with exponential weights $e^{-α|z|^{m}}$ on the complex plane. We prove that when $m>2$, the commutator $[\mathcal B_α,\mathcal B_β]$ is compact on the space $L^{2}(\mathbb C, dA)$ whenever $α,β>0$. We further show that if $m>2$ and $α\neqβ$, then the commutator is never of finite rank.
