If you managed to get a good stand of wheat, make sure you scout closely for aphids. There’s a good bet we will have more aphids than usual this fall because of the warm weather.
If you are managing for high-yielding wheat, then protecting wheat from transmission of barley yellow dwarf virus is important. Below are a couple of points to consider.
• Seed treatments such as Gaucho, Cruiser and NipsIt Inside will generally protect against aphids infestations during the fall (and reduce transmission of barley yellow dwarf virus).
• If a seed treatment was not used, consider making an insecticide application three to four weeks after planting. However, I prefer that you scout first and make this application if and when aphid populations reach 3 or more per foot of row but before populations exceed 8 or more aphids per foot.
Barley yellow dwarf virus may already have been transmitted if you have high aphid numbers. We can often ride low aphid populations into winter during a normal/cooler fall and them clean them up in late winter.
That doesn’t work as well on early-planted wheat or for normally planted wheat during an usually warm fall.
One final point for future consideration. Planting before the recommended window can create a Hessian fly problem. If you planted wheat as a cover crop in September or early October, it’s possible that nearby production fields may inherit problems.
When feasible, avoid planting production wheat immediately adjacent to an early-planted cover crop that also contains wheat.
