Hessian Fly-free Date: Good for Wheat, Cover Crops and Disease
By Andy Michel and Pierce Paul, The Ohio State University
A good rule of thumb for planting wheat is to wait after the Hessian fly-free date. These dates are predictions on when most Hessian fly adults would no longer be alive and lay eggs in wheat fields. If planted too early, the eggs can hatch and stunt or kill the wheat plants. Keep in mind that this date is also good for cover crops as well.
