We derive a covariant formalism to describe {ital D}-wave quarkonium production and annihilation decays in the context of nonrelativistic potential models. We apply it to evaluate the decay rates for such processes as {ital Z}{sup 0}{r arrow}{sup 1}{ital D}{sub 2}+{gamma},{sup 3}{ital D}{sub {ital J}}+{gamma} (where {ital J}=1,2,3) and other previously uncalculated processes. Despite the appearance of relatively large numerical coefficients, we find no case in which {ital D}-wave states (followed by radiative decays) make any significant contributions to inclusive {sup 3}{ital S}{sub 1} quarkonium production.
