Pests in Gardens and Landscapes

Taphrina leaf curl
(Oak leaf blister)—Taphrina spp.

Leaf curl is a fungal disease that is promoted by wet foliage during leaf flush. Taphrina spp. affects many different tree species. Leaves on infected trees become galled, curled, and may drop. Bulges may appear on upper leaf surfaces. Many other factors can cause similar symptoms.



Provide trees with proper cultural care to keep them vigorous. No other control is generally recommended.
