DISEASES OF FOLIAGE PLANTS REVISED LIST FOR 1985

AREC-A Rese rch Report RH-85-2

Diseases play an importa t role in poduion of many crops,
including tropical foliage pl pps As each year pass s, diseases
appear which have not appeared 'be ,e-Uai .@Bhli-ig not appear
which once were common problem-s. ThTfoll iita-ti summarizes
the known diseases of foliage plants described during the last 20
years primarily, with many new diseases only recently discovered.
The list has been revised once before this, the third publication,
and becomes more complete each year. Some diseases such as those
caused by pythiaceous fungi and the Southern blight pathogen occur
on many crops and may not be listed for each crop included in the
table. Another change this year involves the inclusion of nema-
todes as disease-causing agents. The following list should be
used as a guide to the diseases which are likely to occur on the
most common foliage plants and an aide in development of superior
disease prevention programs. There are many publications avail-
able which answer such important questions as what each disease
looks like on each host plant, what is the best control, and what
is the recommended control. It may be especially useful to obtain
*a copy of the "Foliage Plant Note" series which describes culture,
diseases and pests for many common foliage plants.
