IN the past 10 years, oak wilt, caused
by Endoconidiophora fagacearum Bretz,
has become increasingly important as a
destroyer of oak trees in the eastern half
of the United States. It was first described
about 13 years ago as a fungus disease in
Wisconsin (Anonymous 1942), but earlier
reports of dying oaks indicate that it
probably has been present there for the
past 20 years. The studies reported herein are intended
mainly to supply information concerning
the availability of oak wilt inocula
and the relative importance of Illinois environmental
conditions at different times
of the year on the longevity of the causal fungus in nature. It seems that such information
would be applicable in finding the
means of spread of the disease beyond root
graft distances and in selecting and developing
effective control measures.
