Pratylenchus neglectus and P. thornei reduce wheat yields in the Pacific Northwest USA. Resistant landrace cultivars have been identified using controlled environments. Field resistance and tolerance characteristics were compared over three years and two locations for four spring wheat cultivars; the susceptible cultivars Alpowa and Louise, and the resistant landraces...
Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. This publication provides a description and information on biology,...
Cereal cyst nematodes reduce yields of wheat, barley, and oats in the Pacific Northwest states of Idaho, Oregon, and Washington. It is estimated that these pests reduce wheat profitability in these states by at least $3.4 million annually. This publication describes the distribution, biology, damage, management, and detection of cereal...

The cereal cyst nematode Heterodera avenae reduces wheat yield in the Pacific Northwest. Resistance and tolerance traits among spring wheat cultivars were poorly defined. Screening trials were conducted with 39 cultivars over a 2-yr period in irrigated commercial fields that were infested by H. avenae. Comparisons were made between drill...
This report was prepared for the 2009 Range Field Day held at the Columbia Basin Agricultural Research Center in Pendleton, Oregon. It contains research reports on molecular identification of cyst nematodes in wheat and barley; hard red winter wheat production; club wheat breeding in Oregon; growing canola on wide row...

Heterodera avenae is a cereal cyst nematode that reduces wheat yields in the Pacific Northwest USA. Barley is also susceptible but there were no previous reports of resistance or tolerance to H. avenae in the USA. Spring barley cultivars were assayed in H. avenae-infested fields over two years. Cultivars were...
