Please consider attending a workshop focused on late season disease and insect problems in soybeans and corn on Wednesday, August 25th. The workshop will take place at the University of Minnesota Southern Research and Outreach Center in Waseca from 9:00 to Noon.
On-site registration will begin at 9:00 am. Advance on-line registration is available at the University of Minnesota Institute of Ag Professional web site at http://www.extension.umn.edu/AgProfessionals/ The workshop fee is $50 per person at the door, $45 if registered in advance before August 24th. Certified Crop Advisor Continuing Education Units have been applied for in pest management (2.5).
Dr. Dean Malvick, University of Minnesota Extension Plant Pathologist, will lead the disease section that will focus on diagnosis, problems this season, scouting, and disease management options for soybean and corn diseases. The soybean portion will focus on late season disease problems, especially sudden death syndrome (SDS), brown stem rot, white mold, and stem canker. Distribution of SDS , biology of the disease, comparisons between SDS and other diseases of soybean, and factors favoring SDS will be emphasized. Late season corn diseases will also be discussed. The session will include a brief presentation indoors, tours of plots with SDS and other diseases present, and dissection of infected plants . Dr. Ken Ostlie, University of Minnesota Extension Entomologist, will discuss corn rootworm stacks and performance issues while answering questions about what's best for corn growers in regards to selection of corn root worm traits. In this session, we'll discuss the pros and cons of these new developments in corn rootworm management as we examine root protection. Specifically, we'll:
Compare root injury under different rootworm management strategies (none, soil insecticide, single RW trait and stacked RW trait corn).
Discuss recent performance problems with RW trait corn and its diagnosis and documentation
Participants at the workshop will conduct "hands-on" root injury evaluations and tissue testing, which will be used to complement the discussion of current management developments for corn rootworm.
