Soil solarization and soil additives as alternatives to preplant fumigation in annual plasticulture strawberry production
… for soil sterilization of strawberry annual plasticulture production is necessary. This research focused on soil solarization, products including paper pellets, mustard seed meal, and corn gluten meal. Two studies were conducted at the Virginia Tech Hampton Road AREC (Agricultural Research …

Copper Concentrations in Tidal Creeks and Estuaries of the Eastern Shore and the Relationship to Plasticulture and Copper-based Crop Protectants
This project investigates the effect of plasticulture and copper-based crop protectants on water quality on the Eastern Shore of Virginia. Water and sediment copper concentrations in both plasticulture and non-plasticulture containing watersheds were measured to determine the scope of copper in …

Innovative Approaches for Detection and Management of Fruit Rot Diseases in Annual Hill Plasticulture Strawberry Production System
Fruit rot diseases, including anthracnose fruit rot (AFR) and Botrytis fruit rot (BFR) (grey mold) in strawberries, are caused by the acutatum species complex and Botrytis cinerea, respectively. These diseases present a major challenge to sustainable strawberry production in the United States, …

Evaluation of Sedimentation Control as a Best Management Practice for Removing Copper-based Crop Protectants in Plasticulture Runoff
The fate and distribution of copper-based crop protectants, applied to tomato fields to protect against disease, were investigated in a greenhouse-scale simulation of farming conditions in a coastal environment. Following rainfall, 99% of the applied copper was found to remain on the fields sorbed …

Evaluation of anaerobic soil disinfestation using brewers spent grain and yeast inoculation in annual hill plasticulture strawberry production
Anaerobic soil disinfestation (ASD) is a promising alternative to chemical fumigation to control soil-borne plant pathogens and weeds. This research focused on evaluating several locally available carbon sources for ASD on weed control, evaluating the performance of brewers' spent grain (a …

Factors Affecting Mobility of Copper in Soil-Water Matrices
… many crops as a fungicide/bactericide, including plasticulture tomato growing operations. Field tests have shown that copper is sometimes found in ground water near these fields. Therefore, a laboratory study was undertaken to determine if this copper can result from plasticulture application and …

Enhancing Limited-Resource Farmers' Economic, Environmental, and Social Outcomes Through Extension Education
… the Farmers Adopting Computer Training (FACT), Plasticulture, and Pastured-Swine programs have helped enhance limited-resource farmers' economic, environmental, and social outcomes. In addition, the participants confirmed caring, trust, and relationship building as qualities that encouraged …

Land Use Impacts of Plastic Mulch Tomato Production and Evaluation of Sorbent Control on Shellfish Hatchery Operations
… bactericides that are used on the crops. The plasticulture fields were often located adjacent to the same estuaries from which the shellfish hatcheries draw their water. High levels of copper were measured in multiple surface water locations near these fields. Runoff associated with the …

Manipulating Flowering Times and Site Attractiveness To Pollinators To Improve Yield and Fruit Quality in Strawberry
… Fragaria x ananassa ‘Albion’ was planted in plasticulture in a RCBD in Ithaca, NY for the 2022 and 2023 growing seasons. Plants were sourced as four propagule types from different developmental stages to stagger fruiting cycles. These were grown under three interrow cover treatments comprised …

Managing Weeds and Soilborne Pests with Fumigant and Non-Fumigant Alternatives to Methyl Bromide
… as a soil fumigant to manage soilborne pests in plasticulture vegetable production; however, it has been banned by the United Nations Environment Programme. Alternatives to MBr must be implemented to sustain fresh market tomato productivity. Possible MBr alternatives include new fumigant …

An Economic Comparison of High Tunnel and Open-Field Strawberry Production in Southeastern Virginia and A Joint Estimation of Acreage Planted to U.S. Major Crops
This thesis covers two separate studies. The first study, chapter 2, was conducted to evaluate whether there are additional economic returns from producing strawberries in the high tunnel compared to the open-field in Southeast Virginia. We develop and compare budgets for eight strawberry cultivars …
