Field crop health matters throughout the entire growing season. The types of diseases on crops depend on the point in the growing season and the environmental conditions. Many later-season diseases result from soilborne pathogens over which in-season fungicide applications have no control. Most commercial varieties will have ratings for the performance of their selections against various diseases, including those caused by soilborne pathogens.

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.
