Interpretive Summary: Plant-parasitic nematodes, microscopic roundworms, are reported to cause up to $10 billion in crop loss annually in the United States. In the Pacific Northwest of the U.S., there are several types of plant-parasitic nematodes that reduce the yield and productivity of crops such as potato, apple, mint, and wheat. The most important plant-parasitic nematodes in the Pacific Northwest are described in this book chapter, and sustainable methods that may be used to reduce the impact of nematodes on crop productivity are discussed.
Technical Abstract: Agriculture in the Pacific Northwest (PNW) of the United States, including the states Idaho, Oregon, and Washington, is diverse. Combined, over 17 million ha of land are farmed within this region of the U.S. The plant-parasitic nematodes found in this region are also diverse, with 18 economically-important genera reported. Important nematological issues in the PNW include: Meloidogyne chitwoodi and Globodera pallida on potato, Pratylenchus penetrans, P. neglectus, and P. thornei on a diversity of crops, Heterodera avenae and H. flilipjevi on wheat, and Paratichodorus allius on onion and potato. Each of these species uniquely impacts crop productivity and quality and also domestic and international trade in the PNW. While many of the high value crop production systems in the PNW rely upon fumigant and nonfumigant nematicides to manage these nematode, sustainable methods including genetic resistance, crop rotation, amendments, and cover crops are also included as part of sustainable plant-parasitic nematode management plans.
