Effectiveness of Foliar Fungicides by Timing on Northern Leaf Blight on Hybrid Corn in Southeast Iowa

Authors: Alison E. Robertson (Iowa State University) , Myron C. Rees (Iowa State University)

Abstract

Fungicide use on hybrid corn has increased considerably, primarily due to reports of increased yields, even in the absence of disease and higher corn prices. A number of fungicides are registered for use on corn. The objectives of this project were to 1) assess the effect of timing of application of fungicides on disease, 2) evaluate the yield response of hybrid corn to foliar fungicide application, and 3) discern differences, if any, between fungicide products.
