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 ...
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, ...
Population Structure of Uromyces appendiculatus in North Dakota
(North Dakota State University, 2019)
North Dakota is the lead producing state of common bean in the USA, accounting for 43% of national production. Bean rust is caused by the autoecious, macrocyclic fungus Uromyces appendiculatus (Pers.:Pers.). All pathogen ...
Efficacy of Seed Treatments and In-Furrow Fungicides for Management of Dry Bean Root Rot Caused by Rhizoctonia Solani and Fusarium Solani, and Field Pea Root Rot Caused by Fusarium Avenaceum and Fusarium Solani
(North Dakota State University, 2017)
Dry bean and field pea root rots have resulted in substantial yield losses in North Dakota. Root rot symptoms range from small lesions to complete root destruction. Traditional management practices such as seed treatment ...
Evaluation of Genetic Resistance to Common Bacterial Blight in Dry Edible Bean
(North Dakota State University, 2015)
Common bacterial blight (CBB) is an economically important disease of dry bean worldwide caused by Xanthomonas axonopodis pv. phaseoli, (Xap). The objectives of this research were to determine the frequency of CBB resistance ...
Evaluating Chemical Seed Treatments for Fusarium Root Rot Control in Dry Beans and Field Peas
(North Dakota State University, 2014)
This study evaluated commercially available seed treatment products for their ability to control Fusarium solani and F. avenaceum, causal agents of root rot in dry edible bean and field peas, respectively, through in-vitro, ...
Revisiting Management Practices for Diseases of Spring Barley in North Dakota
(North Dakota State University, 2018)
Common barley diseases observed in North Dakota include net blotch, spot blotch, leaf and stripe rust, bacterial leaf streak, and Fusarium head blight. The first objective of this research was to determine the effect of ...
Expression Analysis of the Expanded Cercosporin Gene Cluster in Cercospora beticola
(North Dakota State University, 2018)
Cercospora leaf spot is an economically devastating disease of sugar beet caused by the fungus Cercospora beticola. It has been demonstrated recently that the C. beticola CTB cluster is larger than previously recognized ...
Characterization of Cytochrome B from European Field Isolates of Cercospora Beticola with Quinone Outside Inhibitor Resistance
(North Dakota State University, 2012)
Cercospora leaf spot (CLS), caused by the fungal pathogen Cercospora beticola, is the most important foliar disease of sugar beet worldwide. Control strategies for CLS rely heavily on fungicides including quinone outside ...
Cloning and Characterization of rcs5, Spot Blotch Resistance Gene and Pathogen Induced Nec3 Gene Involved in Programmed Cell Death in Barley
(North Dakota State University, 2019)
Upon sensing pathogens, plants initiating defense responses typically resulting in programmed cell death (PCD). PCD effectively subdues biotrophic pathogens but is hijacked by necrotrophs that colonize the resulting dead ...
