Leaf Galls or Exobasidium Galls
[Image: Azalea Leaf Gall ]The swollen deformed white powdery looking leaves, buds, floral parts and shoot tips of azalea and sasanqua camellia are infected by the fungus Exobasidium or leaf gall. The disease occurs quite often and is dependent on the proper weather conditions for an infection. The disease causes little damage to the shrubs but is unsightly. One control is to remove the affected leaves from the plant by hand picking or pruning. Infected leaves on the ground may be raked up and thrown away. A fungicide may be used in early spring before the new buds break. Suggested fungicides are triadimefon (Bayleton and there are several other trade names) or tribasic copper sulfate.
