In this video, Pioneer Field Agronomist Rodney Erdman discusses the optimal time to apply fungicide to your corn. The right timing can depend on several factors such as planting conditions, plant spacing, or any disease pressure that may be present. For the most efficacy, Rodney recommends waiting until your corn has reached brown silk (VT-R2), ensuring your corn will be protected during critical growing phases. If there is heavy disease pressure, from something such as gray leaf spot, you could be advised to apply earlier to help protect your corn and improve your yield potential come harvest time.
