The first frost of the autumn generally brings a flurry of forage related questions.These questions usually center on three general topics:
• Toxic prussic acid potential and management of frosted sudangrass and sorghum sudangrass hybrids
• Suspected toxicity of frosted alfalfa to grazing animals
• Post-frost harvest of last alfalfa cutting
