The Clearfield® Production System combines high-yielding seeds with broad-spectrum herbicides tailored to regional conditions, delivering efficient, long-lasting weed control, crop quality and global market acceptance. In 2003, in cooperation with leading global and regional seed partners, BASF introduced sunflowers into the growing family of successful Clearfield Production System crops that included canola/oilseed rape, maize, rice and wheat. Within a few years, the Clearfield Production System for sunflower had become known as an essential component in hybrid sunflower oil and confectionary production.
