Abstract

Alfalfa is reportedly in good condition throughout the state with little winter injury and surprisingly few reports of leaf disease problems. But frequent April rains provided good conditions for leaf disease development, and significant levels of spring black stem and leaf spot were reported last week by extension field specialist Brian Lang in northeastern Iowa. The ISU Plant Disease Clinic also has received several samples with either spring black stem, common leaf spot, bacterial leaf spot, or stem blight.
