Abstract

An estimated two million acres of corn were sprayed with fungicides (strobilurin or a strobilurin/triazole combination) in Iowa in 2007. Reasons for spraying vary and include the high price of corn, potential to control diseases, and a possibility of improved yield from "plant health" benefits. Until this year fungicide applications to production corn fields was rarely practiced in Iowa because they were not profitable.
