To evaluate the yield response and return on investment when applying fungicide at the VT growth stage on multiple hybrids.

2016 Multi-Location Corn Fungicide Study - Hybrid Response

In most areas we experienced a lot of heat and moisture throughout the 2016 season. This led to high levels of foliar disease in many cornfields. Each year we look at how hybrids respond to fungicide applications to help maximize yield and profit. Many hybrids react differently based on their genetics so scouting is very important when making management decisions such as a fungicide application. Planting corn after corn increases the odds that you’ll need fungicide compared to corn after soybeans. This year, more hybrids showed a greater response to fungicide due to high disease levels and late-season infections. I suggest continuing to use low-response hybrids in corn after corn rotations and other areas prone to higher disease levels such as bottom fields.
