Crown rot is prevalent in alfalfa fields.  When assessing your field for timing of the first cut, be sure to check the health of plant crowns and roots.  This can be done by digging 5 plants, deep enough to capture about 6 inches of the crown.  To assess crown rot, follow the protocol outlined in the UW-Extension Team Forage publication (A3620) at This publication provides guidelines for assessing whole plant health and images useful for rating alfalfa crown and root health on plants slit in half to check for discoloration.
