The Department of Pesticide Regulation finalized the Intrepid® 2F registration earlier this month. The label must include ‘rice’ and ‘armyworm’ for legal usage, or you must have an approved supplemental label (from Corteva) in your possession.

Please remember the registration is by the trade name Intrepid® 2F and not per active ingredient.
