Screening of Germplasm Accessions from the Brassica Species for Resistance against PG3 and PG4 Isolates of Blackleg
(North Dakota State University, 2011)Blackleg is a disease of canola and rapeseed cultivars that is caused by the fungus Leptosphaeria maculans (Desm.) Ces. & de Not., and it is by far the most destructive pathogen of canola in North America. In recent years, ... -
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 ... -
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 ... -
Studies on the Biology of Soybean Cyst Nematode
(North Dakota State University, 2011)Soybean cyst nematode (SCN), Heterodera glycines, is a threat to soybean production in North Dakota. Studies on the biology of SCN were conducted to improve my understanding and management of this plant parasitic nematode. ... -
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 ... -
Studies on the Population Biology of Colletotrichum coccodes Using AFLP and SCAR Markers
(North Dakota State University, 2010)Black dot is a blemish disease of potato caused by the fungus Colletotrichum coccodes (Wallr.) Hughes. with worldwide distribution. It occurs in Africa, Asia, Australia, Europe, North America, South America, and Central ... -
Towards Identifying the Physical and Molecular Components Involved in Resistance to Leaf Rust Pathogen Puccinia Triticina in Wheat and Barley
(North Dakota State University, 2016)Genetic resistance is the preferred method to reduce yield losses caused by many diseases including wheat leaf rust. However, in many cases host resistance seems to be short-lived. For decades, scientists have tried and ... -
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 ... -
Understanding Programmed Cell Death Pathways by Characterizing Barley Disease Lesion Mimic Mutants
(North Dakota State University, 2021)Programmed cell death (PCD) in plants refers to rapid and localized cell death that occurs as a result of regular biological processes, or in response to infection or injury. Understanding the molecular mechanisms of PCD ...
