Wheat being sprayed

I went to Edwardsville today and saw 2 people spraying wheat.  This made me look up the latest Illinois advice on Nitrogen Application and use of Fungicides in wheat.  I know that the best wheat yields often come on fields where fungicides are applied, but I would still say use with caution.  Fungi easily adapt to fungicides, so if you can avoid them.  On the other hand, waiting too long can reduce the efficacy of fungicides as well.  You need to scout fields often.   I suppose they could h ave been spraying for garlic too.  Harmony is an effective treatment and  often needed to prevent dockage.
