Effect of Anaerobic Soil Disinfestation on Salmonella Concentration Using Different Soil Amendments
Salmonella has been shown to survive in soils for extended periods. Anaerobic soil disinfestation (ASD) represents a promising alternative to fumigation used to manage soilborne diseases and pests; however, little is known about ASD's impact on Salmonella. The study aimed to compare Salmonella …

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 …

The biodegradation of valeric, butyric, propionic and acetic acids in anoxic, subsurface, soil environments
The biodegradation potential of two subsurface soils was characterized by monitoring the biodegradation of short-chain fatty acids in anaerobic soil microcosms. Valerate, butyrate, propionate, and acetate concentrations were monitored independently using separate microcosms. The effect of sulfate …

Bioavailability of metolachlor and glyphosate in aerobic and anaerobic soils
… throughout the globe. Despite the prevalence of anaerobic wet situations in the soil, the predictive capability for the environmental fate and bioavailability of these herbicides is based primarily on well-drained soil conditions. Anoxic events and flooding ubiquitous to agroecosystems may pose a …

Spartina anglica population and environmental studies within the Solent salt marsh system
… in the S. anglica marshes of the south coast, anaerobic soil conditions prevail with impeded drainage being the most likely cause of the dwarf growth forms and lack of re-colonisation of pans and mudflats observed in the field. The thesis concludes that the ultimate demise of the S. anglica …

The Microbubble Assisted Bioremediation of Chlorinated Ethenes
… to deliver hydrogen and carbon dioxide to anaerobic consortia to stimulate their ability to reductively dehalogenate tetrachloroethylene all the way to ethene and ethane. A continuous flow system, consisting of six anaerobic soil column bioreactors, inoculated with sediments from Virginia …

Anaerobic Dissipation of Herbicides in Microbiologically Induced Soil Redox Regimes
… may encounter anaerobiosis as a result of soil flooding, poor drainage, or offsite transport. Anaerobic dissipation of herbicides in the environment is poorly understood. The objective of this research was to characterize the anaerobic fates of herbicides atrazine, trifluralin, and …

Investigating Management Alternatives for Southern Blight on Vegetables in the mid-Atlantic United States
… locally organic materials as carbon sources for anaerobic soil disinfestation (ASD) treatments and their impact on S. rolfsii viability and soil. In a three-year field study, ten commercial potato cultivars and four planting dates per year were evaluated on the Eastern Shore of Virginia. Later …

Innovative Approaches for Detection and Management of Fruit Rot Diseases in Annual Hill Plasticulture Strawberry Production System
… pathogens can survive in the transplants and the soil rhizosphere and later infect the plants. As a first step for disease management, it is crucial to identify plant diseases like AFR in their early stages. In recent years, remote sensing, including multispectral imaging, offers an advanced …

Herbaceous and woody plant establishment across hydrologic gradients in bottomland reforestation sites
… survival and growth. I also evaluated the use of soil magnetic susceptibility (MS), a proxy for soil drainage (other factors being equal), as an easily measured, quantitative predictor of planted tree survival and growth. Lower values of soil MS result from long-term reducing (or anaerobic) soil …

Evaluation of Host Resistance and the Utilization of Organic Amendments to Manage Macrophomina Crown Rot of Strawberry in California
… of strawberries can be severely limited by soilborne plant pathogens, insects and weeds. <em>Macrophomina phaseolina </em>is a problematic soilborne fungal pathogen in California strawberry production inciting the disease Macrophomina crown rot. When established, the pathogen can cause …
