Abstract

In the Pacific Northwest, Heterodera avenae is spreading to soils infested with root-infecting fungal pathogens of wheat. A poorly drained,silty clay loam infested with multiple pathogens was used to examine productivity of winter wheat in 11 crop sequences. Breaks between wheat crops included summer fallow or crops of pea, barley, rape, alfalfa,or Kentucky bluegrass. In the fifth year, winter wheat was planted inall sequences, after one-half of each plot was treated with aldicarb. Yield of annual winter wheat was always 40-60% less than wheat alternated with fallow or any other crop, except alfalfa contaminated with grass weeds. Wheat yielded equally following 1- or 2-yr breaks from wheat. Effective breaks included summer fallow, pea, and weed-free alfalfa. H. avenae was the most important individual constraint to yield. Combined damage from H. avenae and Gaeumannomyces graminis var. tritici caused highest overall yield loss, whereas H. avenae and Pythium spp. had the greatest negative effect on number of roots. During the fifth year, where aldicarb was applied, root damage by H. avenae decreased but damage by Rhizoctonia solani and Pythium spp, increased, resulting in no yield improvement.
