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 ... -
Biology and Management of Fusarium Species on Sugar Beet
(North Dakota State University, 2017)Minnesota and North Dakota together produce about 51% of the beet sugar in the United States of America. Fusarium diseases caused by Fusarium oxysporum f. sp. betae and F. secorum on sugar beet cause significant reduction ... -
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 ... -
Augmenting Fungicidal Activity of Tetraconazole with Chemosensitization Agents for Cercospora Leaf Spot Management
(North Dakota State University, 2017)Cercospora beticola (Sacc.) is the causal agent of Cercospora leaf spot (CLS). CLS is considered to be one of the most destructive foliar diseases of sugar beet in the world. CLS is managed in part through resistant ... -

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 ... -
Sensitivity of Sclerotinia Sclerotiorum Isolates From North Central US to Azoxystrobin and Boscalid
(North Dakota State University, 2016)Azoxystrobin and boscalid are fungicides frequently used to manage diseases caused by Sclerotinia sclerotiorum (Lib.) de Bary in many broadleaf crops in North Central US. . Continued use of these compounds can induce ... -
Rhizoctonia Solani Damping-Off of Sugarbeet: Effect of Plant Growth Stage on Disease Severity and Management Using Penthiopyrad
(North Dakota State University, 2015)Rhizoctonia solani is the most damaging pathogen on sugarbeet (Beta vulgaris L.) in North Dakota and Minnesota. Research was conducted to evaluate penthiopyrad for controlling R. solani and determine when the plants are ... -
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 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 ... -
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 ... -
Sensitivity of Rhizoctonia Solani and Aphanomyces Cochlioides to Fungicides, and Fitness of Tetraconazole-Resistant Isolates of Cercospora Beticola after Exposure to Different Temperature Regimes
(North Dakota State University, 2015)North Dakota and Minnesota produce 55% of USA sugarbeet production. Diseases caused by Rhizoctonia solani, Aphanomyces cochlioides, and Cercospora beticola are the major diseases affecting sugarbeet production in North ... -
