 The Department of Plant Pathology offers graduate studies leading to the
Master of Agriculture, Master of Science, and Doctor of Philosophy degrees.
A superior student with a baccalaureate degree may begin graduate study
toward a higher degree in the basic areas of plant pathology with emphasis
on bacterial, fungal, and viral plant pathogens. Specializations within these
areas include: biochemical aspects of host-pathogen systems, epidemiology,
etiology, genetics of host-pathogen systems, physiology, and taxonomy. The
diversity of cropping sequences coupled with an environment ideal for plant
disease development in Florida is unexcelled and offers the student opportuni-
ties of study with diseases of unique crops as well as diseases of crops of
national and international importance. Intimate knowledge can be gained of
diseases of field, forage, forest, fruit, ornamental, pasture, range, turf, and veg-
etable crops in temperate, sub-tropical, and tropical environments. Students
who anticipate study in plant pathology at the University of Florida should
include in their undergraduate program training in: botany (anatomy, cytol-
ogy, physiology, systematics), chemistry (through organic), introductory bac-
teriology, physics, zoology, one foreign language, and mathematics.
 After termination of the first quarter in residence all students will be given
an oral examination covering the general and specialized areas of plant
pathology. Course requirements will be determined for each individual based on
his performance on the examination as well as his background and objectives.
 The Departments of Botany and Entomology-Nematology offer courses in,
 respectively, mycology and nematology.
