We evaluate the cross sections for the dissociation of J/psi and psi{sup '} by pi and rho at low collision energies, using the quark-interchange model of Barnes and Swanson. The dissociation cross section for J/psi by pi is found to be relatively small with a maximum of about 1 mb and a kinetic energy threshold of 0.65 GeV. The pion-induced psi{sup '} dissociation cross section is found to be much larger, with a maximum of about 5 mb and a lower threshold. Dissociation cross sections for J/psi and psi{sup '} by rho mesons are also evaluated and are found to be large near threshold.
