INDEX OF PLANT DISEASES IN FLORIDA


PREFACE


The Index of Plant Diseases in Florida is a compilation of diseases
affecting the wide diversity of flora which contributes to the enrichment
of the State of Florida. This project is the result of cooperative efforts of
many plant pathologists who have given unstintingly of their time and
expertise over the many months that went into this work.
The data comprising the major portion of these plant disease reports
were compiled from plant disease records and biennial reports of the
Bureau of Plant Pathology. Division of Plant Industry. Florida Depart-
ment of Agriculture and Consumer Services. Gainesville: reports of plant
pathologists throughout the State of Florida; plant disease records of the
Experiment Station Herbarium, Institute of Food and Agricultural Sci-
ences IlFASI. University of Florida. Gainesville: annual reports and
annual research reports. IFAS: bulletins of the Florida Agricultural Ex-
periment Station. IFAS: the Index of Plant Diseases of the United States
SUSDA Handbook 165,: and finally, every available record containing
plant pathological reports for the State of Florida. No attempt has been
made to establish a list of references. The authors felt that this would
serve only a limited useful purpose because a significant portion of this
compendium was derived from many sources, including unpublished
reports.
This index is an attempt to compile and summarize for the first lime
all plant diseases of significance in the State of Florida. This painstaking
effort represents only an initial step toward the establishment of a com-
pendium. as complete as possible, to serve as a reference source for all
persons who have an interest in plant pathology and its related disci-
plines. The magnitude of this work does not imply that this index is
complete or conclusive, for the very nature of plant disease is that it is an
on-going, ever-changing process in plant pathogen-host interaction. It is
hoped, therefore. that this work will serve as an initial basis in establish-
inga ready. useful reference to facilitate the identification ofpat hological
specimens and also provide assistance for the establishment of protective
rules and regulations affecting plant movement. It is also hoped that this
endeavor will be further refined and broadened in the future so as to
reflect the changes which inevitably occur in the dynamic field of plant
pathology.
The Index of Plant Diseases in the United States (Agricultural
Handbook 165) has served plant pathologists and many others as a valu-
able reference source. We selected a similar format for presenting infor-
mation primarily because it is straightforward, easily read. and provides
ready access to information.
We originally wanted at the commencement of this compilation to
include geographical and distribution data relative to diseases of specific
hosts. Though Florida has a diverse array of plant types which are more or
less dictated by climatologic zones, the authors felt that such zones cer-
tainly ldo not represent immutable lines of demarcation with regard to
host-pathogen relationships and as such re of limited significance. Many
representatives of Florida's diverse flora occur in any number of these





climatological hardiness zones which are defined on the basis of average
minimal temperatures. Average temperature data as might be related to
the influence on plant growth would have limited correlation to the
critical analysis of plant disease occurrence.
The scope of this work attempts to provide a compilation ofall parasi-
tic diseases occurring in the State of Florida with emphasis on those of
economic importance, but at the same time not excluding any truly
pathogenic relationship of organisms 'fungi. bacteria, viruses or myco-
plasmasi with plants not considered to he of economic importance -uch as
weeds and non-cultivated plants. Moreover, a diligent attempt has also
been made to restrict the listing of organisms to those which are truly
pathogenic, omitting those organisms which were felt to be saprophytes
or necrophytes. i.e.. organisms which develop on dead plant tissue. An
effort was also made to include microorganisms which are weakly
pathogenic or are believed to exhibit some pathogenic potential.
The scientific names of plants and organisms contained in this work
are based on the guidelines established by the International Rules of
Botanical Nomenclature. including their recognized authorities. A few of
the organisms in this listing lack the author because they were derived
from old reports containing, undoubtedly, names for which no references
were available to the authors. Wherever possible both the perfect and
imperfect states of the organism or those with pleomorphic stages are
included as a cross reference in order to minimize any confusion which
may arise. This is done in the index by indicating the alternate stage in
parentheses. Viruses and physiological diseases, as well as those of un-
known causes, are grouped last in the list of host organisms. Where
common names are available, these are also included to facilitate recogni-
tion of the pathological disorder. Whenever possible, the disease type and
its position of occurrence on the plant are given.
The hosts in this treatment are listed alphabetically. beginning with
the family, followed by the genera with a brief description. under which
are given the host species and their common names. The host species are
numbered, and the numbers are given at the end of those microorganisms
found on the corresponding host. Thus. a species of'Ccrcospora. for exam-
ple. having the numerals in parentheses 1.2.3.1 indicates that it occurs
on the host species 1.2.3.4 enumerated above the group of host organisms.

As stated in the preface, this index is the first ofits kind for the State
of Florida and is the result of a cooperative endeavor between the authors
and the many plant pathologists throughout the State of Florida. The
authors recognize and express heir sincere appreciation to the following
plant pathologists for their assistance in compiling this work: H-. J. Bor-
ders. H. ('. Burnett. M. Cohen. I. S. Cox. J. M. Crall. T. E. Freeman. W. J.
French. C. M. Howarrd .J. P. Jones. R. R. Kincaid. I.. C. Knorr. H. H.
Luke. . O. agie. B. Marlatt. I. T. McMillan, N. C. Schenck. P. L.
Thayer, E. H. Todd, D. P. Weingartner, and T. A. Zitter.
The authors also acknowledge the assistance of L. H. Purdy, Chair-
man. Department of Plant Pathology. University of Florida. Gainesville.
who helped in a most significant way to facilitate the gathering of plant
disease information from the many diverse sources. Finally. the authors
are most grateful for the encouragement and support provided by Halwin
L. Jones, Director of'the Division ofPlant Industry, who made possible the
publication of this work.
To all those mentioned above and many others who have helped in
many various ways. the authors extend their profound gratitude.
