The disease is most active when new growth is wet. Normally the disease attacks in the spring. The new growth will turn brown and when the disease progresses too far, the plant cannot be saved.

What Will Happen To My Landscape?

Repeated damage can result in abnormal bunching and discoloration of the foliage, stunting of young trees or shrubs, or-in severe cases-plant death.

What Can I Do About Phomopsis?

Make sure your plants are in full sunlight in a well-drained area. Do not crowd plants. Air flow and ventilation will discourage disease growth. Prune diseased plants to get rid of infected parts and increase airflow. Disinfect your pruning tool in a bleach solution of one part household bleach to four parts water after each cut. If the infestations are severe, remove and destroy the plants that are infected. Watering plants in the morning through the roots gives the plants the rest of the day to dry off, discouraging establishment of diseases, including Phomopsis. A combination of cultural and chemical control is often required. Most local hardware stores carry fungicides that will control Phomopsis. Because these sprays can cause injury to some plants, read the label thoroughly before using and apply according to the directions. Depending on the severity of the damage, more than one fungicide application may be required for complete control. Combating Phomopsis can be a timely and unpleasant weekend task.
