Inoculation Techniques, Development of Brassica Napus Breeding Lines and Identification of Markers Associated with Resistance to Sclerotinia Sclerotiorum (Lib.) De Bary
(North Dakota State University, 2012)
Sclerotinia stem rot caused by Sclerotinia sclerotiorum (Lib.) de Bary is an economic disease affecting canola (Brassica napus L). Since expression of sclerotinia stem rot symptoms shows much variability and the trait is ...
Characterization of Cytochrome B from European Field Isolates of Cercospora Beticola with Quinone Outside Inhibitor Resistance
(North Dakota State University, 2012)
Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is the most important foliar disease of sugar beet worldwide. Control strategies for CLS rely heavily on fungicides including quinone outside ...
Molecular Characterization and Pathogenicity of Sunflower Stem Pathogens
(North Dakota State University, 2014)
Sunflower (Helianthus annuus L.) production can be limited by several stem diseases.
Among these, Phomopsis stem canker causes frequent yield reductions in Australia, Europe and
North America. In the U.S., while Diaporthe ...
Characterization of Sensitivity of Sclerotinia Sclerotiorum Isolates from North Central U.S. to Thiophanate-Methyl and Metconazole
(North Dakota State University, 2013)
Sclerotinia sclerotiorum (Lib.) de Bary causes Sclerotinia stem rot on canola and many other crops of economic importance in the U.S. SSR is primarily controlled with fungicides applied at flowering time. Most fungicides ...
Downy Mildew of Sunflowers: Establishment of Baseline Sensitivity to Azoxystrobin and Monitoring for the Development of Fungicide Resistance and Plasmopara Halstedii Virulence Phenotype Changes
(North Dakota State University, 2017)
Downy mildew, caused by Plasmopara halstedii (Farl.) Berl. and de Toni, is an economically important disease in cultivated sunflowers, Helianthus annuus L. The objectives of this study were to determine disease pressure ...
Characterization and Identification of Genetic Resistance to Puccinia Graminis F. Sp. Tritici in Triticum Aestivum and Hordeum Vulgare
(North Dakota State University, 2015)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to wheat (Triticum aestivum) and barley (Hordeum vulgare) production. The emergence of the highly virulent Ug99-lineage stem rust races ...
Stochastic Budgeting and Input Breakeven Analysis in North Dakota Potato Production
(North Dakota State University, 2017)
Enterprise budgets were developed for non-irrigated red and irrigated russet potato production, based on North Dakota model farms. Costs and revenues vary among producers, thus budgets are intended to serve as a template ...
Identification and Genomic Analysis of Stagonospora Nodorum Blotch Susceptibility Genes in Wheat
(North Dakota State University, 2014)
Parastagonospora nodorum is a necrotrophic fungal pathogen that causes the disease Stagonospora nodorum blotch (SNB) on wheat. The fungus produces necrotrophic effectors (NEs), that when recognized by corresponding host ...
Marker Assisted Selection Increases the Efficiency of Breeding for Potato Virus Y Resistance in Potato
(North Dakota State University, 2014)
Potato Virus Y (PVY) is an important virus of potato due to the non-persistent mode of transmission by aphids causing yield losses. Genetic resistance is the recommended control since insecticides cannot adequately control ...
Molecular and Histological Study of Sphaerulina musiva-Populus spp. Interaction
(North Dakota State University, 2017)
Sphaerulina musiva, the causal agent of leaf spot and stem canker, is responsible for critical yield loss of hybrid poplar in agroforestry. This research examined quantification of S. musiva in host tissue, and infection ...
