PESTS AND
DISEASES Most insect pests can be
gently washed off, or swabbed with alcohol. Mealy bugs are especially fond of paphs
and like to hide in the leaf axis and flower bud sheaths so examine these
carefully.
If
necessary, use an insecticidal soap or fine horticultural oil formulated for
orchids, after reading all directions and warnings carefully. Paphs have few
insect problems, but are susceptible to bacterial and fungal infections which
can result in brown spots or rotted areas on leaves, which can quickly lead
to the demise of plants. Carefully cut out infected tissue at the earliest
sign of infection with a sterile blade, and spray plants with a
fungicide/bactericide such as Physan. Sprinkling the affected areas with
cinnamon will also help. Good culture will also eliminate most
problems.
