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 ...
Genomics and Management of Fusarium Root Rot of Field Peas
(North Dakota State University, 2012)
Dry Pea or field pea (Pisum sativum L.) is an important cool season legume crop grown in the United States. Field peas are vulnerable to many diseases of which, soil borne diseases including wilt and root rot are of major ...
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 ...
Characterization of Programmed Cell Death Responses Involved in Disease Resistance/Susceptibility Responses in Barley
(North Dakota State University, 2015)
The plant innate immune system relies on regulated programmed cell death (PCD) responses which provide resistance against biotrophic fungal pathogens and are utilized by necrotrophic pathogens. The gene-for-gene interactions ...
Characterization of Pectobacterium carotovorum subsp. brasiliense as a Causal Agent of Sugarbeet Soft Rot
(North Dakota State University, 2018)
A soft rot decay of sugarbeet was observed in commercial fields in North Dakota and Minnesota from 2012 to 2016. Symptoms reported are similar to those for bacterial vascular necrosis and rot caused by Pectobacterium ...
Understanding and Managing Rhizoctonia Solani in Sugarbeet
(North Dakota State University, 2013)
Rhizoctonia crown and root rot of sugarbeet (Beta vulgaris L.) caused by Rhizoctonia solani Kühn is one of the most important production problems in Minnesota and North Dakota. Greenhouse studies were conducted to determine ...
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: ...
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 ...
Pathogenic Variation, Host Specialization and Aggressiveness in Helminthosporium Sativum
(North Dakota State University, 1984)
Common root rot, caused by Cochliobolus sativus, is an important disease of spring wheat and barley in the northern Great Plains. While the disease has been widely studied, extensive systematic investigation of pathological ...
Characterizing Pyrenophora Teres F. Maculata in the Northern United States and Impact of Spot Form Net Blotch on Yield of Barley
(North Dakota State University, 2015)
Pyrenophora teres f. maculata causes spot form net blotch (SFNB) on barley and was recently documented in North Dakota. The impact of SFNB on barley, the genetic diversity of the pathogen, and virulence structure are unknown ...
