The many windy days we have experienced may have brought disease spores from the South and although we are currently in a dry spell, disease spores are prevalent in decaying tissue. Be sure to continue to scout and monitor disease favoring conditions, once this dry spell breaks.
Fungicide costs are down significantly from a few years ago and most of our top producers have seen a nice return on investment by using fungicides. This is especially true in high yielding fields that are either corn-on-corn or which are planted to conventional corn.
Low lying fields are more vulnerable as well as fields planted to less disease susceptible varieties. Insecticides can be mixed with fungicides, but it is important to follow the correct protocol for fields near beehives.
