We study contributions from color-octet quarkonium formation mechanisms to {ital J}/{psi} hadroproduction at low {ital p}{sub {perpendicular}}. We include transitions of color-octet {ital c{bar c}} states into {open_quote}{open_quote}direct{close_quote}{close_quote} {ital J}/{psi} and into {chi}{sub 1,2} which decay radiatively into a {ital J}/{psi}. The leading color-singlet mechanisms analyzed in earlier work and the leading color-octet mechanisms discussed here are found to be insufficient to reproduce the {ital p}{sub {perpendicular}}-integrated {ital J}/{psi} production data. {copyright} {ital 1996 The American Physical Society.}
