DuPont Limited applied to extend the use of Exirel to allow aerial spraying over uneven terrain and during wet conditions. Exirel contains the active ingredient cyantraniliprole, and is already approved for ground-based use to control caterpillars and aphids in fodder brassica crops, such as turnips, swede, forage, rape and kale.
