- 2020 Spray Bulletin for Commercial Tree Fruit Growers: Virginia, West Virginia, and University of MarylandPfeiffer, Douglas G.; Bergh, J. Christopher; Wilson, James; Hooks, C. R. R.; Sherif, Sherif M.; Walsh, C. S.; Yoder, Keith S.; Rahman, Mahfaz; Kotcon, J. B.; Derr, Jeffrey F.; Chandran, Rakesh S.; Frank, Daniel L.; Wycoff, Stephanie B.; Brown, Amy; Parkhurst, James A. (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 from predators with selective chemical application for maintaining pest populations below economic threshold levels. This approach requires that growers give careful consideration to the selection, application rate and timing of chemical sprays. The degree of integration achieved will vary according to the management ability, training and objectives of the orchardist. Inadequate monitoring or implementation of IPM practices will lead to unsatisfactory results. In order to encourage the biological control components of the program, growers must consider the toxicity of chemicals to predators (Table 9, page 59) in addition to their efficacy against fruit pests (Tables 7 and 8, pages 56-58)...

- A characterization of large-scale swine production and manure generation in Virginia counties and cities located within or outside of the Chesapeake Bay WatershedEstienne, Mark J. (2022)Economies of communities in the Chesapeake Bay watershed depend on commercial and recreational fishing, but various pollutants threaten plants and animals native to the region. Agriculture is the largest source of nutrients and sediment entering the Bay. Mathematical models employed to predict the quantity and fate of nutrients entering the Bay from the various land uses determine success in reducing pollutants. Sources of accurate livestock production data allows development of valid decision support tools including models. Livestock populations used in models reflect census data collected every five years by the USDA. The USDA cannot disclose information allowing a reader to determine information for individual farms. Thus, data for some counties within the Bay watershed often are not reported skewing results. The objective of this study was to characterize swine numbers and manure nutrient generation in Virginia and to begin building a database that can facilitate creating mathematical models used by various groups as decision-making tools.

- Mixed Infection of Strawberry Mottle Virus and Strawberry Mild Yellow Edge Virus in the Southeastern United StatesSamtani, Jayesh B.; Johnson, Charles S.; Flanagan, Roy III; Starke, Keith; Poling, Barclay; Martin, Robert (Virginia Cooperative Extension, 2017-10-25)More than 30 viruses and phytoplasmas are known to affect the genus Fragaria. Multiple viruses infecting strawberries (Fragaria xananassa Duch.) can severely affect plant productivity and reduce fruit quality. Complexes of viruses or mixed virus infections in strawberries in an annual production system were not identified in the southeastern United States prior to fall 2012. Within four to six weeks of transplanting strawberries in the fall of 2012 for annual plasticulture production, many growers in Virginia noticed some loss of crop stand and plants that exhibited yellowing along the leaf margins of several younger leaves (as seen in figs. 1 and 2). In some plants, these symptoms progressed to marginal necrosis.

- Southeastern U.S. Vegetable Crop Handbook, 2019Reiter, Mark S.; Arancibia, R. A.; Straw, Allen; Kuhar, Thomas P.; Rideout, Steven L. (Meister Media Worldwide, 2019-01-21)This handbook comprises up-to-the-minute information developed from research and Extension projects conducted throughout the southeastern United States. The key idea behind this handbook is to provide you with a practical resource that conveniently fits on your dashboard. It contains the information that you need to manage your vegetable crops, including which varieties to plant, planting dates, fertilizer recommendations, cover crop selection and conservation tillage options, pesticide selection, grafting, fertigation, plasticulture, postharvest handling, alternative pest management tools and suggestions, as well as many other topics.
