In the conducted studies 13 species ofFusarium were isolated into pure culture from triticale seed. Their pathogenicity was assessed under laboratory and greenhouse conditions. Most of the species studied were highly pathogenic to the first leaf see-

Age-specific life table studies were conducted on the Russian wheat aphid, Diuraphis noxia (Mordvilko), to evaluate the effects of using a barley–benzimidazole agar system on D. noxia growth, reproduction, and survival. Weibull functions, linear an

Sampling summer and fall populations of the Russian wheat aphid, Diuraphis Noxia (Mordvilko), on winter wheat, spring wheat, and barley in the northwestern United States (Idaho, Montana, Oregon, and Washington) from 1988 to 1991 resulted in 120 estim

Several methods for determining yield reduction resulting from Septoria nodorum blotch have appeared in the literature during the past decade. These methods varied from the measurement of effects of disease on components of yield to calculation of ar

Differences in levels of resistance toSeptoria tritici blotch were observed in plants with a specific height-reducing gene. When the gene 'Rht 2' was present either as an isoline or in the progeny, a higher degree of resistance was found. The most su

Fungi from the genus Septoria are known for their ability to incite severe epidemics in Graminae. Over the years a considerable body of literature has accumulated on variation in pathogenicity of two major cereal pathogens from the genus — Septoria

Changes in incidence and severity of Septoria nodorum blotch (SNB) and Septoria tritici blotch (STB) have been noted in recent years in several wheat-growing areas of the world. A questionnaire was designed to identify factors associated with occurre

To develop genetic markers in the fungus Phaeosphaeria nodorum, incitant of leaf and glume blotch of cereals and grasses, genomic DNA from 11 geographically diverse isolates from wheat was used to compare restriction fragment length polymorphisms (RF

Barley powdery mildew was used as a model to evaluate the potential of barley composite cross populations for conservation of disease resistance. The objective was to determine if increases in resistance to powdery mildew could be detected over perio
