Growing Resistance, Oregon Hazelnuts Battle Blight

Although Oregon is known for many exports — from timber to hipster irony — few people are aware that it's actually the country's leading source of hazelnuts.

Growers estimate that 99 percent of the United States' crop comes from Oregon's Willamette Valley. Just a few years ago, the industry was on the verge of collapse due to a disease called Eastern filbert blight. Now, years of research have brought blight-resistant breeds to fruition.

Oregon Hazelnut Industry Sidesteps Blight and Rebounds to a Promising Market

HazelnutsEastern filbert blight is an aggressive, deadly fungus, and the bare, dead branches jutting from the top of Ben Mitchell's older hazelnut trees is its calling card.

Orchardists such as Mitchell could only hope to hold it off by amputating diseased limbs and applying clouds of fungicide. Just a few years ago, it looked like one of the state's signature niche crops would disappear. Oregon produces 99 percent of U.S. hazelnuts, roughly 37,000 tons a year, and a $40 million annual harvest was slipping away.
