Francesco Di Gioia, Ph. D., Assistant Professor of Vegetable Crop Science at Penn State University will discuss anaerobic soil disinfestation (ASD) and how it can be used within high tunnel systems to control soilborne bacteria, fungi, plant-parasitic nematodes, and weeds, as well as to enhance soil fertility. The topic will be covered across two sessions, the first providing an introduction to the technique, its development, the principles of how it works, and how it can be applied. The second will go into greater detail about application, quality of inputs required during the process, as well as how to identify sources for required inputs. Both sessions will feature examples of the practice as applied before planting and during tomato crop production.
