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 ...
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 ...
Genetic and Molecular Characterization of Host Resistance and Susceptibility to Pyrenophora Teres F. Teres in Hordeum vulgare
(North Dakota State University, 2016)
Pyrenophora teres f. teres, a necrotrophic fungal pathogen and causal agent of net form net blotch (NFNB), is an economically important pathogen of barley (Hordeum vulgare) and has potential to cause significant yield ...
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 ...
Biology and Development of Two Wilt Fungi of Potato: Verticilliam Dahliae and Colletotrichum Coccodes
(North Dakota State University, 2012)
The demand for high quality tubers for the frozen processing industry has exerted increased pressure on producers to control diseases that can compromise tuber quality, including, C. coccodes and V. dahliae. Infection of ...
Studies on the Management of Potato Mop-Top Virus-Induced Tuber Necrosis
(North Dakota State University, 2015)
Tuber necrosis caused by the Potato Mop-top Virus (PMTV) has become one of the most important tuber necrosis diseases in the United States. PMTV is transmitted by the powdery scab pathogen (Spongospora subterranea f.sp ...
Spatial and Temporal Sensitivity of Alternaria Species Associated with Potato Foliar Diseases to Demethylation Inhibiting and Anilino-Pyrimidine Fungicides
(North Dakota State University, 2015)
Early blight and brown spot, caused by Alternaria solani and Alternaria alternata,
respectively, are important foliar diseases of potato, affecting both tuber yield and quality. Most
of the commercial cultivars lack ...
Studies on the Development and Management of Powdery Scab and Root Gall Formation Caused by Spongospora Subterranea on Potato (Solanum Tuberosum L.)
(North Dakota State University, 2015)
The biotroph protozoan Spongospora subterranea causes root gall formation and powdery scab on potato. Symptoms on tubers affect directly the quality and marketability of the harvested product while infection in roots are ...
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 ...
