Alfalfa Mosaic Virus Infections in Garbanzo Beans

AMV was first identified on lucerne in the USA and now poses a significant threat to worldwide production of garbanzo beans. AMV has infected garbanzo beans in Arizona and California. In April of 2018, a number of garbanzo fields in central Arizona were heavily infected by AMV and resulted in near complete crop failure.  Depending on virus-cultivar combination and the stage of growth at infection, severe symptoms can be caused by  infection with AMV and yield loss can vary from complete crop failure to decreases in grain yield  and quality.
