Research Update: Mid-Season Fungicide on Corn

Encyclopedia Article

13 Dec 2007 -

An estimated three million acres of corn in Iowa were sprayed mid-season with fungicides (strobilurin or a strobilurin/triazole combination) in 2007. Reasons for spraying included 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 cornfields were rarely practiced in Iowa because they were not profitable. In addition, many of the hybrids grown today have good overall tolerance to foliar (leaf) diseases.
