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 ... -
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 ... -
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 ... -

Parasitic Fitness of SDHI-Sensitive and -Resistant Isolates of Alternaria Solani
(North Dakota State University, 2017)Early blight of potato (Solanum tuberosum L.) is caused by Alternaria solani Sorauer. The single-site mode of action chemistries of the succinate dehydrogenase inhibitors (SDHIs) and quinone outside inhibitors (QoIs) have ... -
Plant-Parasitic Nematodes in Field Pea and Potato and their Effect on Plant Growth and Yield
(North Dakota State University, 2018)In this study, surveys were conducted in pea and potato fields in North Dakota and Central Minnesota to investigate the incidence and abundance of plant-parasitic nematodes in these fields. Moreover, the effect of the pin ... -

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 ... -
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 ... -
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 ... -
State of the University, 2007
(North Dakota State University: Office of the President, 2007-10-04)NDSU is "the university of choice" and is an institution with both success and momentum, according to President Joseph A. Chapman. During his annual State of the University Address, Chapman said, "I know of no other ... -
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 ... -
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 ... -
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 ...
