Map showing alfalfa weevil development

Accumulated growing degree days (GDD) from Jan. 1 to May 14, using a base of 48°F. Larval alfalfa weevils can be found throughout the state. Alfalfa fields should be checked for damage and treated or cut if threshold levels are reached. See the May 1 CropWatch for information on scouting and control options. (Note: The -100 GDD is an anomaly in the mapping program for a select area.)
