Assessment of a Virus Sampling and Detection Method for Water Testing Using Pepino mosaic virus
Mazziero, Beatriz Gallucci (2016-12-01)The aim of this research is to study water sampling as a critical step for detection of unwanted waterborne plant pathogenic viruses that can seriously damage agriculture and the environment. Water sources, such as reservoirs, ... -
EDNA-host: Detection of global plant viromes using high throughput sequencing
Pena-Zuniga, Lizbeth Daniela (2020-05)The aim of this research was to develop the concept of host-specific virome detection methods. Three model systems were selected roses, cucurbits, and water. EDNA MiFi was used to generate pathogen electronic probes ... -
Effects of subinhibitory doses of the fungicide iprodione on the plant pathogens Fusarium oxysporum and F. proliferatum
Freire Zapata, Viviana Estefania (2020-12)Hormetic stimulatory responses have been widely reported in several economically important plant pathogens. Low doses of commonly applied fungicides can enhance fungal traits in vivo and in vitro conditions. However, little ... -
Electrokinetic capillary chromatography methods for separation and detection of aniline and phenol pesticidic metabolites
Wall, William Eric (2003-05) -
Eukaryotic plant pathogen detection through high throughput DNA/RNA sequencing data analysis
Espindola, Andres S. (2016-12)Plant pathogen detection is crucial for developing appropriate management techniques. A variety of tools are available for rapid plant pathogen detection. Most tools rely on unique features of the pathogen to detect its ... -
Evaluation of Tolclofos-methyl for Control of Pod Rot of Peanut Caused by Rhizoctonia Solani in Oklahoma
Inskeep, Patricia McGown (Oklahoma State University, 1987-05-01)Evaluation of fungicides for control of peanut pod rot incited by Rhizoctonia solani in Oklahoma was investigated in this study. Sensitivities to tolclofos-methyl and pentachloronitrobenzene of naturally occurring isolates ... -
Fungicide-induced Hormetic Effects in Plant Pathogenic Fungi and Oomycetes
Pradhan Shrestha, Sumit (2015-05-01)Fungi and Oomycetes pathogens are the causal agents of several plant diseases that often require chemical control. Fungicides are one of the main components in the management of such diseases. Intensive use of few fungicide ... -
Genomic resources for phylogenetics, population genetics and detection of oomycete plant pathogens
Proaño Cuenca, Maria Fernanda (2020-12)Plant pathogenic oomycetes are a diverse group of fungal-like eukaryotes that cause disease in natural and agricultural ecosystems. Due to their biological properties that, in cases, require alternative technologies to ... -
Growth Characteristics of Sclerotinia Minor and Sclerotinia scerotiorum Isolates and the Effect of Post-Inoculation Relative Humidity on Peanut Infection
Brown, Michael Jay (Oklahoma State University, 2010-05-01)Sclerotinia blight is the most costly soilborne disease of peanut in Oklahoma, affecting yield and quality. Though the disease can be caused by both Sclerotinia minor and S. sclerotiorum, S. minor is the predominant species ... -
Novel detection approaches for capillary electrophoresis of pollutants and toxicants
Karcher, Arron (2000-05) -
Peanut cultivar selection for the development of resistance to Sclerotinia blight
Maas, Andrea Lynn (2005-05)Scope and Methods of Study: The objectives of these studies were two fold and Included a study to determine inheritance of resistance to Sclerotinia blight in peanut utilizing detached-shoot inoculations, and a field study ... -
Pythium (Browning) Root Rot and Possible Involvement or Toxins in Disease
Mojdehi, Hamidreza (Oklahoma State University, 1987-05-01) -
Sclerotium rolfsii, a pathogen on apple rootstock in Oklahoma
Tomasino, Stephen Francis (1986-12) -
Susceptibility of weed species to Sclerotinia minor and Sclerotium rolfsii: Epidemiologic implications on peanut disease management
Meador, Christopher Bryan (2006-07)Scope and Method of Study: The purpose of this study was to determine the susceptibility of a selected group of weeds common to Oklahoma and Texas peanut production areas to isolates of S. minor and S. rolfsii, to determine ... -
Temporal and Host Related Variation of Pythium and Globisporangium Species in Floricultural Crops
Proano Cuenca, Maria Fernanda (2016-12-01)Several species of Pythium and Globisporangium cause damping off of seedlings, seed rot, stem lesions, and root rot in greenhouse ornamental crops. Two hundred seven isolates from three greenhouses located in Long Island, ... -
Water potential interaction with host and pathogen and development of a multiplex PCR for Sclerotinia species
Abd-Elmagid, Ahmed (2012-07)Scope and Method of Study: Soil water potential (Ψ) is an important parameter that affects the development of plant diseases. Sclerotinia blight of peanut caused by S. minor and S. sclerotiorum has been chosen as a model ...
