Alison Robertson, corn pathologist with Iowa State University Extension and Outreach, will discuss current concerns with tar spot and fungicide timing.
Graduate students Mitchell Baum and Kyle King will discuss interactions between plant density and nitrogen rates on economic optimum ranges and yearly variability of the economic optimum N rate for corn.
Gentry Sorenson and Angie Rieck-Hinz, field agronomists with Iowa State University Extension and Outreach, will discuss current crop management topics including planting date impacts on yield potential, crop development and pest issues. Depending on planting and herbicide application timing, an optional tour of the herbicide mode of action demonstration plots will be available to tour.
