Abstract:: Pratylenchus neglectus is one of the most widespread and economically important nematodes that invades plant roots and restricts wheat productivity in the Pacific Northwest. It is challenging to quantify P neglectus using microscopic methods for studies that require large-scale sampling, such as assessment of rotation crops, wheat cultivars, and other...

Abstract:: Heterodera avenae and H. filipjevi are economically important cyst nematodes that restrict production of cereal crops in the Pacific Northwest United States and elsewhere in the world. Identification of these two species is critical for recommending and implementing effective management practices. Primers were designed from the internal transcribed spacer (ITS)...

Abstract:: 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...

Abstract:: 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...
