Abstract

Fungicide use on hybrid corn has increased considerably in the past two growing seasons primarily due to reports of increased yields, even in the absence of disease and higher corn prices. The objectives of this project were to assess 1) the effect of foliar fungicide timing of application on foliar disease development and stalk rot severity of hybrid corn, and 2) evaluate the yield response of hybrid corn to foliar fungicide timing.
