Seed Production 

• Fields last harvested in mid May for hay and left for seed production should be ready to harvest during the first two weeks of August.
  
• Scouting seed production fields for weeds is the only way to know they are present.
  
• Aside from clean-up of volunteer alfalfa along field borders to remove sources of infestation, there is no effective control for alfalfa seed chalcid.
