The following presentations are in this session:

8:00 AM - 8:30 AM Soil and Crop Management Practices for Minimizing Damage by Nematodes and Diseases George S. Abawi
    It is well known that agricultural production systems greatly impact the population and damage of plant pathogens, especially soilborne pathogens. Traditional farming systems have for centuries employed sustainable production practices to effectively manage plant diseases. A great deal of attention has been paid recently to soil management practices that promote soil quality and health. Thus, the challenge is to assure that the promoted soil management practices will also effectively manage or suppress nematodes, diseases and other crop pests. Case-study examples will be presented and discussed to illustrate the effects of selected production systems and various soil management practices on the root-knot nematode, lesion nematode and root rots of beans.



8:30 AM - 9:00 AM Ecological Approaches to Weed Management Matt Liebman
    Concerns over herbicide resistance in weeds, declining farm profitability, and chemical damage to the environment and human health have led a growing number of farmers and scientists to seek weed management strategies that are less reliant on herbicides and more reliant on ecological processes. Because of their fixed root and seed bank habits, terrestrial weeds can be profoundly affected by soil and plant factors in their immediate environment. Results of work in my research group indicate that crop diversification techniques (e.g., rotation, intercropping, and cover cropping) and organic matter amendments to soil (e.g., composts and animal manures) can contribute to weed management through a variety of mechanisms, including allelopathy, shifts in competitive relationships, and attack by soil-borne pathogens and seed predators. Data from field plot, glasshouse, and laboratory experiments investigating these topics will be presented and some suggestions for future research work will be provided.
