Effectiveness of Foliar Fungicides by Timing on Foliar Diseases on Hybrid Corn in Southwest Iowa

Authors: Alison E. Robertson (Iowa State University) , Dallas L. Maxwell (Iowa State University)

Abstract

Foliar fungicides remain an input on hybrid corn that many farmers consider. New fungicides for use on corn are registered annually. The goal of this project is to provide data to help farmers determine the need for foliar fungicides in their production. The objectives of this project were to 1) assess the effect of timing of application of fungicides on foliar disease, 2) evaluate the yield response of hybrid corn to foliar fungicide application, 3) discern differences, if any, between fungicide products, and 4) to investigate the effect of nitrogen on fungicide yield response.
