Agricultural Practices Influence Salmonella Contamination and Survival in Pre-harvest Tomato Production
(Frontiers, 2018-10-16)Between 2000 and 2010 the Eastern Shore of Virginia was implicated in four Salmonella outbreaks associated with tomato. Therefore, a multi-year study (2012-2015) was performed to investigate presumptive factors associated ... -
Co-Enriching Microflora Associated with Culture Based Methods to Detect Salmonella from Tomato Phyllosphere
(PLOS, 2013-09-09)The ability to detect a specific organism from a complex environment is vitally important to many fields of public health, including food safety. For example, tomatoes have been implicated numerous times as vehicles of ... -
Contrasting Role of Temperature in Structuring Regional Patterns of Invasive and Native Pestilential Stink Bugs
(PLOS, 2016-02-29)Objectives Assessment and identification of spatial structures in the distribution and abundance of invasive species is important for unraveling the underlying ecological processes. The invasive agricultural insect pest ... -
Cover Crop, Rootstock, and Root Restriction Regulate Vegetative Growth of Cabernet Sauvignon in a Humid Environment
(American Society for Enology and Viticulture, 2011-09)Cover crops, rootstocks, and root restriction were evaluated as means to regulate vegetative growth of Cabernet Sauvignon grapevines in a humid environment. Treatments were arranged as a strip-split-split plot with row-middle ... -
Differential Usefulness of Nine Commonly Used Genetic Markers for Identifying Phytophthora Species
(Frontiers, 2018-10-03)The genus Phytophthora is agriculturally and ecologically important. As the number of Phytophthora species continues to grow, identifying isolates in this genus has become increasingly challenging even by DNA sequencing. ... -

Ecological prevalence, genetic diversity, and epidemiological aspects of Salmonella isolated from tomato agricultural regions of the Virginia Eastern Shore
(Frontiers, 2015-05-07)Virginia is the third largest producer of fresh-market tomatoes in the United States. Tomatoes grown along the eastern shore of Virginia are implicated almost yearly in Salmonella illnesses. Traceback implicates contamination ... -
Effect of vertical shoot-positioned, smart-dyson, and Geneva double-curtain training systems on Viognier grape and wine composition
(American Society for Enology and Viticulture, 2008-03)Viognier grapes grown in northern Virginia and resultant wines were evaluated as a function of training system. Treatments included vertical shoot-positioned (VSP), Smart-Dyson (SD), and Geneva double curtain (GDC), with ... -
Effects of horticultural oils on the photosynthesis, fruit maturity, and crop yield of winegrapes
(American Society for Enology and Viticulture, 2002)The effects of horticultural oils on grapevine photosynthesis, fruit maturity, and crop yield components in field experiments were evaluated. Three applications of a 1.5% (v/v) oil/water emulsion were made to Chardonnay ... -
Effects of prohexadione-calcium on grape yield components and fruit and wine composition
(American Society for Enology and Viticulture, 2004)Prohexadione-calcium (prohexadione-Ca) was applied to field-grown Cabernet franc, Cabernet Sauvignon, Chardonnay, and Seyval to evaluate rates and timing effects on fruit yield components and on fruit and wine composition. ... -
Jikradia olitoria ([Hemiptera]:[Cicadellidae]) transmits the sequevar NAGYIIIβ phytoplasma strain associated with North American grapevine yellows in artificial feeding assays
(Library of the University of Arizona, 2019-01-02)North American Grapevine Yellows (NAGY) is a destructive disease of grapevines caused by phytoplasmas, wall-less bacteria that are insect-transmitted and found in plant phloem tissues. Although the disease was recognized ... -
Metagenome tracking biogeographic agroecology: Phytobiota of tomatoes from Virginia, Maryland, North Carolina and California
(Academic Press, 2018–12-05)Describing baseline microbiota associated with agricultural commodities in the field is an important step towards improving our understanding of a wide range of important objectives from plant pathology and horticultural ... -
Mycelial growth, sporulation, and survival of Monilinia fructicola in relation to osmotic potential and temperature
(Mycological Society of America, 1999)The effects of osmotic potential (Psi) and temperature on mycelial growth, sporulation, and survival of Monilinia fructicola were determined using potato-dextrose agar (PDA) amended with KCI and sucrose. Comparatively, KCl ... -
Non-Native Ambrosia Beetles as Opportunistic Exploiters of Living but Weakened Trees
(PLOS, 2015-07-02)Exotic Xylosandrus spp. ambrosia beetles established in non-native habitats have been associated with sudden and extensive attacks on a diverse range of living trees, but factors driving their shift from dying/dead hosts ... -
Oxygen stress reduces zoospore survival of Phytophthora species in a simulated aquatic system
(Biomed Central Ltd, 2014-05-13)Background The genus Phytophthora includes a group of agriculturally important pathogens and they are commonly regarded as water molds. They produce motile zoospores that can move via water currents and on their own ... -
Phytophthora aquimorbida sp nov and Phytophthora taxon 'aquatilis' recovered from irrigation reservoirs and a stream in Virginia, USA
(Mycological Society of America, 2012-04)Two distinct subgroups (L2 and A(-2)) were recovered from irrigation reservoirs and a stream in Virginia, USA. After molecular, morphological and physiological examinations, the L2 subgroup was named Phytophthora aquimorbida ...
