Alert Details

Lingering concerns for corn rootworm beetle pressure remain in latest maturing and planted fields mainly along and north of I-80 this week with the likely greatest pressure now focusing north of the I-90 corridor. The vast majority of fields are now past critical growth stages for this pest so only Low risks are in the forecast now for potential isolated problems, but growers should continue to scout fields where pressure has been noted as this may affect planting intentions in 2020. Otherwise, the overall risk for corn rootworms this growing season has subsided and the risk is likely to be removed from the forecast late this week or next week.
