With the weather forecast in the 90s for July, the most significant disease expected is Grey Leaf Spot. When deciding whether or not to apply fungicide, the gut reaction tends to be based on corn prices. Yes the price of corn has an impact on the profitability of apply fungicide, but there are other decision drivers to consider.
You should consider these big time drivers for fungicide response:
Crop Rotation – If you are on corn after corn, expect a much higher response to fungicide than normal
Tillage Method -Reduced-till, no-till or strip-till create higher amounts of residue that can harbor diseases.
Another helpful tip is understanding the hybrid’s response to fungicide application. We have a great partnership with WinField United and they do several tests comparing hybrids with and without fungicide application. This helps us inform you of the genetic predispositions of various hybrids and their response to foliar fungicide.
