A quark-model picture which incorporates SU(6){sub {ital w}} symmetry is utilized to calculate the weak {Delta}-nucleon-meson and {Delta}-{Delta}-meson parity-violating vertices for {pi}, {rho}, and {omega} mesons, thus extending previous work in the nucleon sector. The effective quark Hamiltonian is based upon the renormalization-group-corrected Weinberg-Salam model. The calculated parity-violating vertices are used to determine the coupling constants in an effective baryon Hamiltonian. We give best'' values as well as estimates of the ranges of uncertainty.
