Mites on Baldcypress

September 2, 1998

Mites on baldcypress have been found at The Morton Arboretum in northeastern Illinois. The damage appears as leaf yellowing and interior browning. In some cases, the entire plant has turned an orangish brown. Some of the tips are dwarfed and distorted. Looking at the foliage with a microscope, one can see a lot of discarded skins on the older, brown foliage. The distorted tips had many mites crawling on them. Control can be obtained with sprays of insecticidal soap, dicofol (Kelthane), fenbutatin-oxide (Vendex), or other miticide. Two sprays one week apart should provide control.
