Armstrong Research and Demonstration Farm
Fungicide use on hybrid corn has increased considerably in the past three 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) evaluate the yield response of hybrid corn to foliar fungicide application, 2) compare the yield response of various products and timing of application, and 3) to assess the effect of fungicide application on stalk rot development.
