Corn acres treated with fungicides have increased with increasing corn profit margins. University recommendations suggest fungicides should be applied to corn when foliar diseases are present, hybrids lack disease resistance and environmental conditions are suitable for increased disease development. Growers have been encouraged to apply fungicides to protect yield and the cost of the application will off-set by grain yield. At the Graves Chapple Research Center, University of Missouri, a fungicide application was applied to different corn hybrids in 2011, 2012 and 2013 with the goal measuring the impact of the fungicide application on corn yield.  In 2011, Quadris was applied at a rate of 16 ounces per acre and during 2012 and 2013, Headline was applied at 6 ounces per acre with 23 gallon of water as a carrier. The fungicide treatment was applied using an off-set boom attached to a front-end loader tractor. Data from all three years across corn hybrids indicated that no significant yield response from the application of fungicide to different corn hybrids compared to the non-treated.
