Integrated Pest Management Options

Planting resistant or highly resistant varieties is the best means of control. The fungus is spread primarily on the cutting bar of forage harvesting equipment. Before harvesting, clean the cutting bar with a 1% solution of bleach followed by a clean water rinse and oil spray. Cut the youngest fields first, working towards the oldest fields. Wait 2-3 years between alfalfa crops. Maintain a good weed control program, since some weeds can be alternate hosts.

Seed Treatment

Comments (Days to harvest, label precautions, etc.)
Alfalfa only. Do not graze treated areas or feed clippings from treated areas to livestock.
