2020 Spray Bulletin for Commercial Tree Fruit Growers: Virginia, West Virginia, and University of Maryland
(2020)Integrated pest management (IPM) is the approach emphasized in this guide; some aspects of IPM are incorporated throughout, although this guide mainly deals with the chemical component of IPM. IPM combines biological control ... -
Aerial high-throughput phenotyping of peanut leaf area index and lateral growth
(Springer Nature, 2021-11-04)Leaf area index (LAI) is the ratio of the total one-sided leaf area to the ground area, whereas lateral growth (LG) is the measure of canopy expansion. They are indicators for light capture, plant growth, and yield. Although ... -
Age related differences in phylogenetic diversity, prevalence of Shiga toxins, Intimin, Hemolysin genes and select serogroups of Escherichia coli from pastured meat goats detected in a longitudinal cohort study
(BMC, 2020-07-30)Background: Little is known on significance, diversity and characteristics of gut E. coli in goats despite their importance as food animals globally. We characterized the temporal dynamics in diversity of E. coli in fecal ... -
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 ... -
Analyzing the structural shifts in U.S. boxwood production due to boxwood blight
(Horticultural Research Institute, 2021-09-01)The purpose of this study is to examine the changes in the sales of boxwood (Buxus spp.) that have occurred in boxwood production states. We theorize that some of the shifts in production areas over the period from 2009 ... -
Apple miRNAs and tasiRNAs with novel regulatory networks
(2012-06-15)Background MicroRNAs (miRNAs) and their regulatory functions have been extensively characterized in model species but whether apple has evolved similar or unique regulatory features remains unknown. Results We performed ... -
Application of Exogenous dsRNAs-induced RNAi in Agriculture: Challenges and Triumphs
(Frontiers, 2020-06-25)In recent years, RNA interference (RNAi) machinery has widely been explored by plant biologists for its potential applications in disease management, plant development, and germplasm improvement. RNAi-based technologies ... -
Applications of High-Resolution Imaging for Open Field Container Nursery Counting
(MDPI, 2018-12-12)Frequent inventory data of container nurseries is needed by growers to ensure proper management and marketing strategies. In this paper, inventory data are estimated from aerial images. Since there are thousands of nursery ... -
Assessing nitrogen and phosphorus removal potential of five plant species in floating treatment wetlands receiving simulated nursery runoff
(2019-02)The feasibility of using floating treatment wetlands (FTWs) to treat runoff typical of commercial nurseries was investigated using two 8-week trials with replicated mesocosms. Plants were supported by Beemat rafts. Five ... -
Assessing the Enzymatic Hydrolysis of Salmon Frame Proteins through Different By-Product/Water Ratios and pH Regimes
(MDPI, 2021-12-08)The enzymatic hydrolysis of fish by-product proteins is traditionally carried out by mixing ground by-products with water. In addition, pH control is used to avoid pH drops. Higher costs are involved due to the use of pH ... -
Assessing the Role of Cyberbiosecurity in Agriculture: A Case Study
(Frontiers, 2021-08-19)Agriculture has adopted the use of smart technology to help meet growing food demands. This increased automation and associated connectivity increases the risk of farms being targeted by cyber-attacks. Increasing frequency ... -
Assessment of the Impact of Viticulture Extension Programs in Virginia
(2016-10)The study discussed in this article assessed the impact of Virginia Cooperative Extension (VCE) on the Virginia wine grape industry. An online survey was developed and administered to members of the Virginia Vineyards ... -

Bark and wood tissues of American elm exhibit distinct responses to Dutch elm disease
(Nature, 2017-08-02)Tolerance to Dutch elm disease (DED) has been linked to the rapid and/or high induction of diseaseresponsive genes after infection with the fungus Ophiostoma novo-ulmi. Although the fungal infection by O. novo-ulmi primarily ... -
Baseline survey of the anatomical microbial ecology of an important food plant: Solanum lycopersicum (tomato)
(2013-05-24)Background Research to understand and control microbiological risks associated with the consumption of fresh fruits and vegetables has examined many environments in the farm to fork continuum. An important data gap however, ... -
Behavioral Response of the Brown Marmorated Stink Bug (Hemiptera: Pentatomidae) to Semiochemicals Deployed Inside and Outside Anthropogenic Structures During the Overwintering Period
(2017-06)The brownmarmorated stink bug, Halyomorpha halys (Stal), is an invasive species from Asia capable of causing severe agricultural damage. It can also be a nuisance pest when it enters and exits anthropogenic overwintering ... -
Biological control agent Rhizobium (=Agrobacterium) vitis strain ARK-1 suppresses expression of the essential and non-essential vir genes of tumorigenic R. vitis
(2019-01-03)Objective To gain insights into the virulence suppressive mechanism of a nonpathogenic strain of Rhizobium vitis ARK-1, we co-inoculated ARK-1 with a tumorigenic (Ti) strain of R. vitis to examine the expression of two ... -
Biology, Crop Injury, and Management of Thrips (Thysanoptera: Thripidae) Infesting Cotton Seedlings in the United States
(Entomological Society of America, 2011-10-01)Several species of thrips are known to infest cotton seedlings in the United States and constitute one of the most common insect pest challenges for growers. The species complex, species abundance, extent of crop injury, ...
