With corn and soybean prices sharply lower than they were a year ago, many growers are looking for ways to cut expenses. But cutting out the use of fungicides may not be a wise choice. Andrew Fisher with Syngenta says, “Our data that goes back almost a decade from Indiana, Ohio, and Illinois that shows a V5 application in corn results in an 8-12 bpa increase in yield. Even with corn at $3.25 that is a $26.00 benefit and that is about a 2 to 1 ROI with Quilt XCel.” Fisher told HAT the figures for soybeans are about the same, “With an R1 application, a grower can see a 6-8 bpa increase with the use of Quadris Top SB fungicide and that is about a 3 to 1 return.”
Not only will fungicides help with disease prevention and control in this cold wet year, but they have the proven benefit of improving plant health, especially in early crop development. Fisher said better root development and stalk strength in corn are benefits that will help improve yield and plant health, “We see greener plants, and that leads to better photosynthesis, and that will really help boost crop development when conditions are cool with a lack of growing units.” He added there are few crop inputs that can consistently deliver these kind of benefits and return on investment year after year.
He stated that the timing of application for corn is rapidly approaching, “The optimal time for application in corn is the V5 state.” Fisher urges growers to walk their fields and assess the stage of their crops and be ready to apply, “If we get some heat in the next few weeks this crop will take off quickly, so don’t let the crop get ahead of you.” He said, in soybeans, the optimal time is R3, which this year will not likely be reached until late June or early July.
His overall recommendation is to sharpen the pencil and really look carefully at what factors are likely to improve yield. He said it is years like this one with less than optimal planting and early growing conditions where the use of a fungicide can have the most dramatic yield impact.
