Soybean Disease Diagnosis & Management
I conduct both applied and basic research into the management of soybean diseases. My applied research has emphasized objectives that are directly related to management of soybean diseases in Minnesota. Those objectives have included: 1) Identification of the yield limiting pathogens of soybean, 2) Determining the interactions of agricultural management practices with soybean pathogens. 3) Evaluation of soybean cultivars and plant introductions for resistance or tolerance to the major diseases and 4) Improving both awareness and management of soybean diseases found in Minnesota.
My basic research has dealt with questions that can lead to a more detailed understanding of the behavior of hosts and pathogens at the level of both individual organisms and populations. Those questions include: 1) Environmental and edaphic factors required for pathogen reproduction, dispersal, and subsequent disease development, 2) The effects of environmental and edaphic factors on host characteristics contributing to disease susceptibility, and 3) Host-pathogen interactions that affect the characteristics of pathogen populations.
