Bradford Pear
Leaves
There are several rusts (Gymnosporangium spp.) that
occassionally are
found on Bradford pear. These
usually develop as yellow spots in late spring becoming orange
with age. By
mid-summer there may be tube-like protuberances on the bottom of
the leaves. This
disease requires two hosts in alternation. You may find on
cedars nearby brown
dimpled galls, sometimes with gelatinous orange material oozing
from them.
Application of fungicides should begin when the flower buds swell
and continue at
about two week intervals up to a month past the end of the
flowering period.
