An extension of the Parker bound on the flux [ital scrF] of magnetic monopoles leads to a stronger bound than obtained previously. The survival and growth of a small galactic seed field requires [ital scrF][le]10[sup [minus]16]([ital m]/10[sup 17] GeV) cm[sup [minus]2] s[sup [minus]1] sr[sup [minus]1]. This new limit rules out the possibility that monopoles much lighter than 10[sup 17] GeV/[ital c][sup 2] can provide the closure density of the Universe.
