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 ...
Resistance Screening and QTL Mapping in Wheat and Triticale Against Root-Lesion Nematode
(North Dakota State University, 2020)
Root-lesion nematode (RLN, Pratylenchus neglectus) invades the roots of wheat and causes yield losses throughout the world. Genetic resistance is the most economical and effective means to manage RLNs. The objective of ...
Determination of Disease Impacts on Sunflower Yield
(North Dakota State University, 2020)
Diseases that infect sunflower frequently occur in North Dakota, but the impact they have on yield is unclear. The objectives of this research are to 1) evaluate fungicide efficacy, application timing and yield impact of ...
Identification and Characterization of Novel Cercospora beticola Necrosis-Inducing Effectors
(North Dakota State University, 2021)
Cercospora beticola is a hemibiotrophic fungus responsible for Cercospora leaf spot disease of sugar beet (Beta vulgaris). Plant pathogens such as C. beticola utilize “effector” molecules to aid in disease establishment. ...
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 ...
Developing a New Inoculation Method, and Evaluating the Potential Biological Control of Rhizoctonia solani by Penicillium pinophilum on Sugar Beet
(North Dakota State University, 2020)
Rhizoctonia solani causes damping-off, and root and crown rot of sugar beet (Beta vulgaris L.) and overwinters as sclerotia and mycelia. Research was conducted to determine how best to produce large quantities of sclerotia ...
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 ...
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 ...
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: ...
