There are only handful of herbicides labeled for cereal rye. UPL has registered Audit 1:1 for postemergence applications. Audit 1:1 is a prepackaged mixture of thifensulfuron plus tribenuron at a 1:1 ratio. The rate is 0.6 to 1 oz/A and needs to be applied before the flag leaf is visible. Audit 1:1 can be tank mixed with other labeled herbicides. Audit 1:1 will control a number of broadleaf weeds, see label for more details.
