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 ...
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 ...
Evaluation of Winter Wheat Germplasm for Resistance to Stripe Rust and Leaf Rust
(North Dakota State University, 2014)
Wheat leaf rust, caused by Puccinia triticina (Pt), and wheat stripe rust caused by P. striiformis f. sp. tritici (Pst) are important foliar diseases of wheat (Triticum aestivum L.) worldwide. Breeding for disease resistance ...
Genetics of the Host-Pathogen Interaction in the Barley-Net Form Net Blotch System
(North Dakota State University, 2017)
Pyrenophora teres f. teres is a fungal pathogen that causes barley net form net blotch. To evaluate the genetics of resistance in barley, a RIL population was developed using resistant barley lines CI5791 and Tifang and ...
Characterization of Effector Encoding Genes from the Novel Sugar Beet Pathogen Fusarium Secorum
(North Dakota State University, 2015)
A new disease of sugar beet, named Fusarium yellowing decline, was recently found in in the Red River Valley of MN and ND. This disease is caused by a novel pathogen named Fusarium secorum. Pathogens such as F. secorum ...
Prevalence of Pathogenicity Groups of the Blackleg Species Complex on Canola in North Dakota
(North Dakota State University, 2011)
North Dakota is the leading producer of canola (Brassica napus) in the United States. Blackleg, caused by two species of Leptosphaeria, L. maculans (Desm.) Ces & De Not and L. biglobosa, is an economically important disease ...
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 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 ...
