TAPHRINA DISEASES PDF Print E-mail
Ever wonder which disease is the first discussed in the wonderful reference Disease of Trees and Shrubs (a must reference) from Cornell's Wayne A. Sinclair and Howard H. Lyon? Come on, admit it, this was your bedtime reading last night. Well, leading off this spring and every spring is PEACH LEAF CURL, caused by Taphrina deformans and a number of other Taphrina diseases. We tend to mostly see peach leaf curl (T. deformans) and oak leaf blister (T. caerulescens), but other diseases may occur, such as plum pocket (T. communis) and cherry leaf curl and witches' broom (T. wiesneri). These fungi cause leaf curling and distortion on new growth, starting with infections of leaves soon after they have emerged from the bud - in other words, already. Fruit growers have already included control applications in their spray schedules. Control applications are rarely warranted in the landscape.
