Most wheat is at a Feekes scale of 8.0 or older; this is often called the mid jointing stage. At this growth rate wheat is about five to seven days ahead of normal heading date. You need to spray as late as possible per the label of fungicide used, because most fungicides do not translocate well in the plant. Additionally, during this time be sure to protect the head of wheat Feekes 10.3 and the flag leaf. You may want to add insecticide to help control aphids and stink bugs.
Headline , Stratego, Quilt, Quadris, Folicur+Tilt , or one of many others.
All should be put out per the label of fungicide used. Most full heading (10.5) should occur before April 17, 2015.
