Effectiveness of Foliar Fungicides by Timing on Hybrid Corn

Fungicides were rarely used on hybrid corn prior to 2007, however, in the past few years, some farmers have included fungicides in their common crop production, particularly as the value of grain has increased. Fungicides are recommended for foliar disease management to protect yield potential. There also have been reports of increased yields in the absence of disease. A number of fungicides are registered for use on corn. The objectives of this project were to evaluate the yield response of hybrid corn to foliar fungicide application at various timings.
