  It was conjectured in arXiv:1211.2788 that bosonization of singular vectors
(in Neveu-Schwarz sector) of $\mathcal{N}=1$ super analog of the Virasoro
algebra can be identified with Uglov symmetric function. In the paper we prove
this conjecture. We also extend this result to the Ramond sector of
$\mathcal{N}=1$ super-Virasoro algebra.
