(North Dakota State University, 2010)Rhizoctonia root rot caused by Rhizoctonia solani (Kuhn), is the most important problem faced by sugarbeet (Beta vulgaris L.) grm.vers in North Dakota and Minnesota. Research was conducted that may be used to manage the ... -
Impacts of Soybean Cyst Nematode (Heterodera Glycines) on Sugarbeet (Beta Vulgaris) and Interactions with Rhizoctonia Solani
(North Dakota State University, 2014)Soybean cyst nematode (SCN), Heterodera glycines is in the same genus as the sugarbeet cyst nematode (SBCN) Heterodera schachtii, there has been concern that SCN could also penetrate sugarbeet roots. The objectives were: ... -
Improving Disease Management in Field Pea and Durum Wheat in the MonDak Region
(North Dakota State University, 2021)Results from wilt pathogenicity and race evaluations for 25 North Dakota Fusarium oxysporum f.sp. pisi (Fop) isolates conducted in the greenhouse indicated all Fop races exist in North Dakota. Race 2 isolates were more ... -
Improving Management and Understanding of Major Diseases of Sugar Beet
(North Dakota State University, 2022)Sugar beet is a sugar-yielding crop, that contributes 25% of the global sucrose production. Economic production of sugar beet is hampered by Cercospora leaf spot (CLS) (Cercospora beticola), Rhizoctonia crown and root rot ... -
Inoculation and Spread of Dickeya in Potatoes
(North Dakota State University, 2019)Field experiments were conducted in two different growing environments to evaluate the spread and movement of Dickeya dadantii. A procedure to inoculate seed potatoes with Dickeya dadantii was developed to use during this ... -
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 ... -
Managing Economically Important Diseases of Sunflower and Oilseed Rape in North Dakota, California, and Schleswig-Holstein
(North Dakota State University, 2021)Rust, caused by Puccinia helianthi, and blackleg, caused by Leptosphaeria maculans, are economically important diseases on sunflower and oilseed rape, respectively. In order to recommend the most effective disease management ... -
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 ... -
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 ... -
Molecular Genetic Characterization of Ptr ToxC-Tsc1 Interaction and Comparative Genomics of Pyrenophora tritici-repentis
(North Dakota State University, 2018)Tan spot of wheat, caused by Pyrenophora tritici-repentis, is an economically important disease worldwide. The disease system is known to involve three pairs of interactions between fungal-produced necrotrophic effectors ... -
Molecular Mapping of QTL for Genetic Transformation-Related Trait and CRISPR/Cas9-Mediated Gene Editing in Wheat
(North Dakota State University, 2022)Plant transformation is a valuable tool for gene characterization and crop improvement. However, wheat transformation is greatly impacted by genotype dependency for successful regeneration of the transgenic plants. For ... -
Movement and Accumulation of Candidatus Liberibacter Solanacearum in Potato Plants
(North Dakota State University, 2012)A new disease affecting potatoes was first detected in Mexico in 1993. Affected plants had aerial symptoms similar to those caused by potato purple top and psyllid yellows, but tubers had internal brown discoloration when ... -
