Should you spray fungicide on your corn

This is not one of my most timely posts, but I know some of you are still making fungicide decisions especially to the north.  No-till Farmer sent out Five Answers to using Foliar Fungicides in Corn.  The information is good for helping to decide.  Really the overriding factors are Susceptibility and disease pressure.  I don't think it is an issue this year, but they say there is not an economic benefit to using fungicide for drought resistance.  Obviously you will need a better yield bump for $3 corn than for $8 corn.  Also keep in mind that fungcides are only effective for a limited number of sprayings, so you might  want to save it for when you really need it.
