The following presentations are in this session:

1:45 PM - 2:05 PM Green manures and soil community management to suppress plant diseases Linda L. Kinkel [Download Presentation/Summary ]
    Naturally-disease suppressive soils offer an attractive model for managing plant diseases: long-lasting, stable, and effective disease suppression. Disease suppression in these soils is commonly a function of microbial activities. Data from a Minnesota suppressive soil suggest that both the density and phenotypic diversity of antibiotic-producing bacteria within the soil microbial community are important predictors of disease suppressive activity. Green manures offer one potential strategy for active management of the soil microbial community to produce selective enrichment of the densities and diversities of antibiotic-producing bacteria in soil, and for the induction of pathogen suppressive activity in agricultural soils. 



2:25 PM - 2:45 PM Successes as a Distributor of Biocontrol Products Jan C. Meneley [Download Presentation/Summary ]
    Jan Meneley will present some practical aspects of biological control with disease suppressing products. The challenges he faces in selling good products include educating academics, wholesale commercial suppliers, and end users. How can we better utilize the role of microbials in IPM?



2:45 PM - 3:15 PM Biologically Based IPM Strategies for Disease Management Walter R. Stevenson and Jana S. Lamboy [Download Presentation/Summary ]
    This session will focus on the incorporation of biologically-based tactics in disease management as well as impediments to expanded adoption of biopesticides. Three speakers with expertise in soil biological diversity and the practical use of biocontrol strategies for disease management will be invited to discuss their perspectives on development and use of biologicals and composts to suppress plant diseases. The session format will allow each speaker 20 minutes followed by a panel discussion with questions from the audience and from the organizers that will focus on how disease management programs can benefit from increased adoption of bio-based tactics.



2:05 PM - 2:25 PM Integrating biological controls for management of field and storage diseases of potato Barry J. Jacobsen [Download Presentation/Summary ]
    This paper will provide an overview of biological control of potato diseases. Special attention will focus on biological control of Rhizoctonia solani in the field and the storage diseases Fusarium dry rot and silver scurf. Both unlabelled Bacilli and labelled Pseudomonas products (Biosave) control products will be discussed. In addition the new concept of mycofumigation will be introduced and both field and laboratory studies with a range of potato pathogens will be discussed.
