To evaluate the use of various additives, applied with a fungicide at the VT growth stage, in an attempt to increase plant health, yield and profitability.

2016 Multi-Location Corn Fungicide Additive Study

With the exception of an insecticide or adjuvant, adding products to fungicide in corn near tassel time is an uncommon practice in most areas. Nutrient assimilation research has proven that corn plants take up the majority of their phosphorus (P), sulfur (S), boron (B), and zinc (Zn) after the V14 growth stage. In addition, tissue sampling corn at R1 (silking) in many areas has often revealed low levels of B and Zn. In 2016, our PFR fungicide additive research indicated mixed results. Additional research needs to be conducted to determine if a positive ROI can be consistently achieved from applying products like Eagle or Boron Plus® with a VT fungicide in corn. In general, I usually recommend that farmers consider a micronutrient product containing B and Zn with a VT fungicide in corn. However, other non-nutritional products such as Eagle may be able to provide some agronomic and economic benefits.
