Alfalfa is a vigorous and productive crop. Like all crops, however, alfalfa is subject to stand and yield loss from diseases, insect injury, nutrient deficiencies and other environmental stresses. Prompt and accurate diagnosis of a problem can allow early treatment to modify or correct the situation before yields are seriously affected or stands are lost. The purpose of the Alfalfa Analyst is to provide an identification guide to some of the more important alfalfa yield and stand limiters. Please use it to help identify any alfalfa problems you may have. Then secure specific up-to-date management recommendations from your local Extension service. ~ Download the full publication at Alfalfa.org.
