Abstract
VERTICILLIUM WILT is a plant
disease caused by the fungus Verticil-
Hum albo-atrum Reinke and Berthold.
This pathogen is peculiar in tliat it does
not confine its attacks to one host, or
a few closely related hosts, as is so
frequently the case with most other
pathogenic fungi; it attacks a large
number of widely unrelated plants,
many of which are of economic importance.
The disease does not often
occur in forest stands, but it is becoming
increasingly prevalent in plantings
of ornamental trees and shrubs,
particularly in temperate regions of the
world. The present study initiated in 1970
and completed in 1972 deals with ( 1
the influence of root wounds and age
of wounds on infection, (2) penetration
and development of the fungus in
susceptible and resistant woody hosts,
(3) analysis of the growth response of
young tree seedlings after root infection,
(4) the influence of temperature
and heat treating of soil on development
of V. albo-atrum in excised roots,
and (5) laboratory and greenhouse
evaluation of fungicides against V.
albo-atrum.
This report is adapted from a thesis
submitted to the University of Illinois
in partial fulfillment of requirements
for the degree of Doctor of Pliilosophy
in Plant Pathology.
