2023 Armyworm Monitoring Update
Week of September 11
Moth numbers peaked the week of September 4, which means that this and next week is when we would see the most worms in the field. However, in our larval searches we have found very few worms. It might not hurt to look closely at worm levels this week, especially in late planted fields that are still in early heading and grain filling.
We will be removing the traps from fields next week. We thank all collaborating growers for letting us put traps and search for worms in the field. Happy harvest!
