Effectiveness Of Foliar Fungicides By Timing On Hybrid Corn, Alison E. Robertson, John M. Shriver, David Rueber

Northern Research and Demonstration Farm

Fungicide use on hybrid corn has increased considerably in the past several growing seasons, 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 standability, 2) evaluate the yield response of hybrid corn to foliar fungicide application, and 3) discern differences, if any, between fungicide products.
