Management Tips

• Extremely high winds caused lodged corn in some SW Minnesota counties. For a discussion of the impacts of lodging at this date see Dale Hicks' Crop News article at: http://www.extension.umn.edu/cropenews/2004/04MNCN16.htm.
• A spreadsheet to estimate time to soybean aphid threshold and scouting frequency can be found at http://www.soybeans.umn.edu/crop/insects/aphid/aphid_sagemodel.htm. Refresh your screen to view this page.
• Do you need prompt, accurate information on plant disease? View the University of Minnesota's Plant Disease Clinic website for information on submitting samples.
