It's business as usual for most of

CREC Faculty Member
Selected as APS Fellow
Dr. James [Jim] H. Graham has been named a Fellow
of the American Phytopathological Society.
This award is presented to only .25 percent of
the active membership of the society each year.
Initially, he worked on soil-borne organisms such as
Phytophthora and developed assay procedures for
these pathogens and determined their affects on
yields of citrus. His work demonstrated that a new
species for Florida citrus, P. palmivora, was responsible
for epidemics of brown rot of fruit, attacked roots
of normally resistant rootstocks, and caused a serious tree decline in association
with the root weevil, Diaprepes. Graham demonstrated that normally beneficial,
soil-borne mycorrhizal fungi could become parasitic when plants had adequate
phosphorus. See Graham on page 3



las been required lnullmerouls rimes in
the I)ast Fe\ ',ears. Hoi\e.er, \itrh all
the new employees, plus it never hurts
to have a reminder or two, here are a
few tips just in case.
Normally, there is plenty of time to
prepare for a hurricane. Use this time
to get your home, automobiles, and
families ready. In fact, now is a good
time to purchase items such as non-
perishable food, bottled water, pet
food, etc. [For a complete shopping list,
go to http://www.polk-county.net/
This is also the perfect time to give
supervisors current telephone numbers
and addresses. This information is used
to contact employees before and after
an emergency.

but smaller than a htiuirriciae. Winds associated w-ith these
storms are less than 74 I1m1)ph, It can still cause MAidesl)read
damage and flooding. Trol)ical storm watches are made for

Tropical Storm Warning: Thiswarning means that tropical

storm conditions, including possible sustained winds of 39-
73 mph are expected in specific coastal areas within 24 hours.

Hurricane Watch: These watches are made for specific
coastal areas. These are not warnings. These watches mean

Watches are usually issued 24-36 hours )lrior to landfall.

Hurricane Warning: This warning Imeans that a hurricane

Measures must be taken illmediatel',. These warnings are
usually issued 24 hours prior to landfall. Howe.er, if the
