We prove the null controllability in large time of the following linear parabolic equation involving the Grushin operator with an inverse-square potential
$$u_t-Delta_{x} u-|x|^{2}Delta_{y}u-frac{mu}{|x|^2}u=v1_omega$$
in a bounded domain
({Omega=Omega_1times Omega_2subset mathbb{R}^{N_1}times mathbb{R}^{N_2} (N_1geq 3, N_2geq 1})) intersecting the surface {
x = 0} under an additive control supported in an open subset
({omega=omega_1times Omega_2}) of
({Omega}).
