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 ...
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: ...
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 ...
The Effect of Substitution of Cytoplasmic Organelles on the Responses of Wheat to Foliar Pathogens
(North Dakota State University, 2016)
Parastagonospora nodorum and Pyrenophora tritici-repentis are foliar pathogens of wheat, capable of causing up to 50% yield losses, and reduced grain quantity and quality, by infecting wheat leaves and kernels. The most ...
Phenotypic Characterization of Leptosphaeria maculans Pathogenicity Groups Aggressiveness on Brassica napus
(North Dakota State University, 2015)
One of the most destructive pathogens of canola (Brassica napus L.) is Leptosphaeria maculans (Desm.) Ces. & De Not., which causes blackleg disease. This fungus produces strains with different virulence profiles (pathogenicity ...
Seed to Seedling Transmission of Colletotrichum lindemuthianum in Dry Edible Pinto Bean
(North Dakota State University, 2015)
Dry bean anthracnose, caused by Colletotrichum lindemuthianum, is a damaging disease that can cause significant reductions in seed quality and yield. The purpose of this study was to determine the races of C. lindemuthianum ...
Identification of Host Resistant Effective against the Barley Spot Form Net Blotch Pathogen
(North Dakota State University, 2014)
Spot form net blotch (SFNB) caused by Pyrenophora teres f. maculata is a major foliar disease of barley (Hordeum vulgare L.) worldwide. SFNB epidemics have recently been observed in major barley producing countries, ...
