The purpose of this study is to evaluate the use of different fungicides, applied at different growth stages, and their effects on yield and profitability.

2019 Multi-Location Wheat Fungicide Study - Foliar

The Feekes 8 growth stage, or flag leaf emergence, is a critical stage in wheat development. The flag leaf produces approximately 75% of the photosynthates necessary for grain fill, so protecting it from disease and insects at this time is critical for overall wheat yields. Fungicides can also be applied later in the growing season, up until flowering (Feekes 10.5. 1), to help protect the plant later in the grain fill period. This study compared the two application timings to see when the maximum return on investment (ROI) would be achieved. With unseasonably high amounts of rain, we observed a positive ROI from all three fungicide treatments; however, Miravis® Ace took home the win and kept the plant healthy through harvest.
