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, ...
Plant-Parasitic Nematodes on Sugarbeet in North Dakota and Minnesota
(North Dakota State University, 2019)
Field surveys were conducted in the Red River Valley (RRV) of North Dakota and Minnesota during 2016 and 2017 to determine the incidence, abundance, and distribution of plant-parasitic nematodes (PPNs) on sugarbeet. ...
Genetically Dissecting the Recessive Rpg4-Mediated Wheat Stem Rust Resistance Locus in Barley
(North Dakota State University, 2014)
The rpg4-mediated resistance locus (RMRL) in barley provides recessive resistance against wheat stem rust (Puccinia graminis f. sp. tritici) races including the virulent race TTKSK (a.k.a Ug99). Three genes (HvAdfF3, Rpg5, ...
Evaluation of Field Pea Varieties for Resistance to Fusarium Root Rot Pathogens
(North Dakota State University, 2017)
Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root ...
Ellucidation of RPG4/RPG5-Mediated Resistance Against Wheat Stem Rust in Barley
(North Dakota State University, 2015)
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to barley and caused devastating reductions in yield and economic losses. The barley line Q21861 was identified as the best source of ...
Characteristics and Host Range of a Novel Fusarium Species Causing Yellowing Decline of Sugarbeet
(North Dakota State University, 2013)
In 2008, a novel and distinct Fusarium species was reported in west central Minnesota causing early-season yellowing and severe decline of sugarbeet. This study was conducted to (i) establish optimum conditions for fungal ...
