A new article recently released through the Crop Protection Network (CPN) discusses how to make fungicide decisions in corn and soybean, given the delayed planting scenarios across the Midwest. The article takes into account yield potential at various planting times throughout the North Central region, as well as the previous wet and cool conditions when evaluating for a positive return on investment, in 2019. Also considered in the article is the potential damage that frost can do to overall yield, which also impact your return on investment. 

With the 2018 growing season coming to an end, it’s time to bust out the record books and begin logging the most prevalent diseases we’ve seen this year in Iowa soybeans. It’s important to review  these diseases so that farmers, agronomists and all of our partners can make informed decisions ahead of next year’s season. These decisions include variety selection, choosing seed treatments, developing pre-germination checklists, evaluating the cost-effectiveness of a fungicide application, and cultural practices such as crop rotation.

Several soybean diseases have become noticeable after recent rainfall across the state.

The following diseases are currently showing up regularly across Iowa soybean fields, depending on your location in the state:
