CAUTION. For demonstration only. This model relies on widely cited peer-reviewed published research, but extensive field data collected in 2022 and 2023 by the Poveda Lab at Cornell University show these degree-day models do not accurately predict adult emergence in New York State. Work is ongoing to create a new, more accurate risk assessment for seedcorn maggot in field crops.

User Inputs


IMPORTANT NOTICE. This seedcorn maggot model uses research from the midwest United States but has lower predictive ability under New York State growing conditions. Work is scheduled in 2023 to improve accuracy and precision using 2022 adult population data from more than 80 farms across NY.
