Branching fractions of decays of heavy quarkonia $psi(3770)$, $psi(4040)$, and $Upsilon(10580)$ to the states $pi^+pi^-$, $Kbar K$, $omegapi^0$, $omegaeta$, $omegaeta^prime$, $rhoeta$, $rhoeta^prime$, $K^astbar K+c.c.$, $rho^+rho^-$, $K^astbar K^ast$ etc are evaluated in the model of the Okubo - Zweig - Iizuka rule violation due to the real intermediate states of mesons with open open heavy flavors. The results are compared with existing experimental upper bounds.
