An April freeze damaged spring alfalfa regrowth across the state. These stands were weakened and are recovering slowly. Late April rainfall has led to an abnormally high incidence of leaf and stem diseases in areas of southern and western Iowa. Growers are encouraged to review their forage inventories and needs and to take a close look at the stand density and health of taproots and crowns in their existing fields. If the taproots and crown tissue still appear normal, and stand densities are adequate, producers are encouraged to plan to harvest the remainder of the haying season.
