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 ...
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 ...
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, ...
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 ...
