Improving Disease Management in Field Pea and Durum Wheat in the MonDak Region
(North Dakota State University, 2021)
Results from wilt pathogenicity and race evaluations for 25 North Dakota Fusarium oxysporum f.sp. pisi (Fop) isolates conducted in the greenhouse indicated all Fop races exist in North Dakota. Race 2 isolates were more ...
Resistance Screening and QTL Mapping in Wheat and Triticale Against Root-Lesion Nematode
(North Dakota State University, 2020)
Root-lesion nematode (RLN, Pratylenchus neglectus) invades the roots of wheat and causes yield losses throughout the world. Genetic resistance is the most economical and effective means to manage RLNs. The objective of ...
Determination of Disease Impacts on Sunflower Yield
(North Dakota State University, 2020)
Diseases that infect sunflower frequently occur in North Dakota, but the impact they have on yield is unclear. The objectives of this research are to 1) evaluate fungicide efficacy, application timing and yield impact of ...
Identification and Characterization of Novel Cercospora beticola Necrosis-Inducing Effectors
(North Dakota State University, 2021)
Cercospora beticola is a hemibiotrophic fungus responsible for Cercospora leaf spot disease of sugar beet (Beta vulgaris). Plant pathogens such as C. beticola utilize “effector” molecules to aid in disease establishment. ...
Developing a New Inoculation Method, and Evaluating the Potential Biological Control of Rhizoctonia solani by Penicillium pinophilum on Sugar Beet
(North Dakota State University, 2020)
Rhizoctonia solani causes damping-off, and root and crown rot of sugar beet (Beta vulgaris L.) and overwinters as sclerotia and mycelia. Research was conducted to determine how best to produce large quantities of sclerotia ...
The Effect of Variable Seed-Borne Inoculum Load of Dickeya dianthicola on Performance and Infection of Field Grown Potatoes
(North Dakota State University, 2020)
Field experiments were conducted at Live Oak, Florida, and Rhodesdale, Maryland, to evaluate the effect of variable seed-borne inoculum load of Dickeya dianthicola on potato plant emergence, plant growth throughout the ...
Characterization and Detection of Bacterial Pathogens of Common Bean
(North Dakota State University, 2022)
Common bacterial blight (CBB) (Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans pv. fuscans (Xff), halo blight (Pseudomonas savastanoi pv. phaseolicola (Psp)), and bacterial brown spot (P. syringae pv. syringae ...
Development of Quantification and Diagnosis Methods for Cereal Bacterial Leaf Streak Pathogens
(North Dakota State University, 2022)
Bacterial leaf streak (BLS) has been a major disease on wheat and barley in the Northern Great Plains. It is caused by Xanthomonas translucens pv. undulosa (Xtu) on wheat and X. translucens pv. translucens (Xtt) on barley. ...
Characterization of North Dakota Hard Red Spring Wheat for Stem and Stripe Rust Resistance
(North Dakota State University, 2022)
Puccinia graminis f. sp. tritici (Pgt) and Puccinia striiformis f. sp. tritici (Pst) are causal agents of devastating wheat stem and stripe rust diseases, respectively. Both diseases sporadically occur in North Dakota (ND), ...
