Corn producers who want to control foliar diseases with a fungicide have a new tool. The fungicide Stratego, from Bayer Corp., is now registered for use on this crop. Stratego is a combination of two active ingredients, propiconazole and trifloxystrobin. Propiconazole has been used on corn for nearly a decade as the active ingredient in Tilt fungicide. Trifloxystrobin is a new product in the strobilurin family, which also includes azoxystrobin, the active ingredient in Quadris.
