description: Using data samples of 89 fb$^{-1}$, 703 fb$^{-1}$, and 121 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider at center-of-mass energies 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, we study the exclusive reactions $e^+e^- \to ωπ^0$, $K^{\ast}(892)\bar{K}$, and $K_2^{\ast}(1430)\bar{K}$ (Charge-conjugate modes are included implicitly). Significant signals of $ωπ^0$, $K^{\ast}(892)^0\bar{K}^0$, and $K_2^{\ast}(1430)^-K^+$ are observed for the first time at these energies, and the energy dependencies of the cross sections are presented. On the other hand, no significant excesses for $K^{\ast}(892)^-K^+$ and $K_2^{\ast}(1430)^0 \bar{K}^0$ are found, and we set limits on the cross section ratios $R_{\rm VP} = \frac{σ_B(e^+e^-\to K^{\ast}(892)^0\bar K^0)} {σ_B(e^+e^-\to K^{\ast}(892)^-K^+)}&gt;$ 4.3, 20.0, and 5.4, and $R_{\rm TP} = \frac{σ_B(e^+e^-\to K_2^{\ast}(1430)^0\bar K^0)} {σ_B(e^+e^-\to K_2^{\ast}(1430)^-K^+)}
