Ferrero, the company that makes Nutella and spreads joy across the world, currently uses about one-fourth of the world’s hazelnut supply. As prices rise, more farmers around the world have begun growing hazelnuts. But it wasn’t possible to do so in the northeastern region of the U.S. – until now…”All the green leafy things you see here are hazelnut trees. But in the beginning, they all used to die from disease,” says Thomas Molnar, a Rutgers plant scientist who is in charge of this effort. About 10 years ago, though, a plant breeder at Rutgers named C. Reed Funk embarked on a quest for hazelnut trees that could survive Eastern Filbert Blight.
