We calculate the contribution of a superstring-inspired heavy diquark to the four-jet rate in e+e- collisions. We find that Z-decay data with charm-quark tagging, corresponding to an integrated luminocity of 20-100 pb-1, will set a bound of 50-60 GeV on the diquark mass. We argue that this is a rather model-independent result.
