Increasing the Odds of a Profitable Yield Response to Foliar Fungicide Application on Corn
During the 2007 growing season, approximately 3 million acres of corn were sprayed with a foliar fungicide. Yield responses due to a fungicide application varied widely. Data compiled from university trials in 12 Corn Belt states and Ontario, Canada in 2007 showed an average yield response of 3 bu/acre to applications of corn fungicides (Bradley, 2008). Among the industries from on-farm trials, BASF reported an average yield increase of 12 to 16 bu/acre, Bayer CropScience an average yield increase of about 10 bu/acre and Syngenta an average yield increase of 15 to 20 bu/acre (Farm Industry News, Feb 15, 2008).
