Aphids, particularly the bird cherry oat aphid, are abundant in many fields. Scouting this past week indicates that fields that are heading to flowering have had the larger populations of aphids when compared to younger fields. The bird cherry oat aphid prefers to feed on foliage, so parting the canopy reveals their presence lower in the plants.

Nitrogen losses through leaching and denitrification associated with the heavy rainfall this season have become significant in parts of the state. The most severely nitrogen-stressed wheat fields appear yellow and yields will obviously be negatively impacted. Other fields that have excellent yield potential may come up short on grain protein at harvest if nitrogen demand during grain filling exceeds the amount available from the soil.
