  Isospin violating mixing of \rho- and \omega-mesons is reconsidered in terms
of propagators. Its influence on various pairs of (\rho^0,\omega)-decays to the
same final states is demonstrated. Some of them, (\rho^0,\omega)\to\pi^+\pi^-
and (\rho^0,\omega)\to\pi^0\gamma, have been earlier discussed in the
literature, others (e.g., (\rho^0,\omega)\to\eta\gamma and (\rho^0,\omega)\to
e^+e^-) are new in this context. Changes in partial widths for all the decay
pairs are shown to be correlated. The set of present experimental data, though
yet inconclusive, provides some limits for the direct (\rho\omega)-coupling and
indirectly supports enhancement of \rho^0\to\pi^0\gamma in comparison with
\rho^{\pm}\to\pi^{\pm}\gamma, though not so large as in some previous
estimates.
