In Virginia, juniper tip blight is caused by one of two different fungi, Phomopsis juniperovora or Kabatina juniperi. Symptoms of the two diseases are identical; however, some aspects of their control differ. Therefore, correct identi cation of the causal agent is important. These fungi can also attack other hosts, including Cryptomeria, Chamaecyparis, and Thuja species. They seldom cause signi cant damage in landscapes unless weather conditions become favorable for disease development. However, they can be very destructive in seedbeds, cutting beds, and lined-out stock in nurseries, or in mass landscape plantings that receive overhead irrigation.
