Kabatina Tip Blight
The symptoms of Kabatina tip blight appear on junipers in late winter or
early spring, even though the primary infection period is in the autumn. The
infection itself often occurs in small wounds caused by insect feeding or
mechanical damage. There is currently no fungicide labeled for control of this
disease. Here is what to look for:
- In February and March, the terminal 2 to 6 inches of diseased branches
throughout the juniper turn dull green, then red or yellow, and finally
- With a hand lens, at the base of the dry, brown foliage, you should see
small ash gray to silver lesions dotted with small black fruiting bodies of
- The brown, desiccated foliage drops from the tree in late May or June.
It is good to remember that the blighting of the foliage occurs only in the
spring. It does not continue into the summer. Also, the disease is restricted to
the branch tips, so it does not cause extensive branch dieback or tree death.
You should prune out the dead tips.
Again, there is no fungicide rated for control of Kabatina tip blight, but
there are certain cultural practices that can reduce the severity of the
- Increase spacing between plants so that there is adequate air circulation.
- Avoid wounding plants with lawn equipment.
- Do not over fertilize.
- Prune out diseased branch tips.
- When purchasing junipers, choose from among those that are resistant to
this disease. Call the Extension Office for an updated list of disease
resistant juniper cultivars.
