Armstrong Research and Demonstration Farm
Foliar fungicides have become an input on hybrid corn that many farmers consider. New fungicides for use on corn are registered annually. In 2017, three companies were interested in comparing an application made at V12 with applications made at R1. The goal of this project is to provide data to help farmers determine if foliar fungicides could be incorporated into their production. 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.
