Crop Minute Week of July 26

July 28, 2010

Making decisions about application of foliar fungicides on corn is tricky, according to Alison Robertson, ISU Extension field crops pathologist, in this week's crop minute.

Research shows there needs to be disease pressure in order for producers to see increased or protected yields as a result of fungicide application. To determine presence of disease pressure, Robertson recommends to start by getting out of the truck and getting into the field. It is the ear leaves and those above the ear leaves that need to be protected.
