The UK Ag Weather Center’s degree day (DD) model for alfalfa weevil indicates that many counties in Kentucky are likely to exceed 190 DD (used as a starting point to begin scouting) by the third week of March. Once temperature accumulations reach 190 DD, growers are advised to look at their alfalfa fields and begin alfalfa weevil larval counts. So far, degree day accumulations for this year are trending close to average for the last 10 years. For more information, visit the Kentucky Pest News article here.
