June 24-30, 2007 is designated as
Lightning Safety Week. The theme for this
year's campaign is "When lightning roars,
go indoors". Lightning ranks #2 in storm-
related deaths in the US- flooding is #1.
There are on average 100 deaths each year caused by
lightning. There are many more injuries from lightning
strikes- only 10% of victims are killed; 90% will survive but
will suffer from life-long injury and disability. In central
Florida lightning safety should be a high priority since we are
the "lightning capital of the world". Florida ranks number 1 in
the number of lightning casualties. The area between Tampa
and Orlando is known to be a very active area for lightning
activity. This is caused from daytime heating coupled with a

To the Bitter End
J.W. Noling, Alicia Whidden, and Phyllis Gilreath

Each year the price of methyl bromide and chloropicrin
content of the methyl bromide formulation increases. As we
have repeatedly indicated, this is an expected outcome of an
established economic principal of supply and demand in-step
with a long protracted phase-out, and it will only get worse
before it gets better. There was a time late this past spring
when we thought an apparent threshold had been crossed and
strawberry growers would begin the transition to alternatives.
The motivating factors for transition were formulation and
price, i.e., a projected price of $4 per lb and only a
formulation of 50/50 to be available from the distributors. It
seemed apparent to us that the price of methyl bromide had
finally exceeded a growers threshold value of 'willingness to
pay', particularly after we repeatedly heard that "I will quit

moisture laden atmosphere and the collision
of sea breezes that usually happen right over
our area and give us many afternoon
thunderstorms with lots of lightning. A
person's odds of being struck by lightning is
1 in 3,000 and since we are in the "lightning
capital" and work outside our odds are
probably much higher so we need to learn
the facts about lightning and how to protect
ourselves, our families and our employees.

Lightning Facts: Lightning can strike as far
away as 10 miles from the rainstorm. The
maximum you can hear thunder is about 10
miles so if you can hear it, you are within
striking distance and should take cover. Also
lightning can come from debris clouds that
come after the initial thunderstorm has
broken up. This is why most victims are
struck before and after the rainstorm; most
people seek shelter while it is raining.
Thunder travels at 1 mile per five seconds so
counting the number of seconds between the
visible flash and the big bang of thunder we
hear and dividing by 5 can give a rough
estimate as to the distance of the lightning
from you.
Central Florida has been found to
have the greatest flash density- a square
kilometer of land is struck 16 times each
year. Lightning activity has an annual cycle.
There is a rapid increase in May which peaks
in July and then a rapid decrease in
September. Through the winter the flash
rate will continue to decline with January
being the lowest. In a 24 hour cycle more
lightning will occur during afternoon and
early evening between 12:00 and 8:00 p.m.
with the peak about 4:00.

Lightning Medical Facts: Lightning causes
nervous system injury and may affect the
brain, autonomic nervous system and the
peripheral nervous system. If someone is
struck by lightning first call 9-1-1. Death is
caused by cardiac arrest and/or breathing is

stopped so after calling 9-1-1 give the victim
CPR or mouth-to-mouth resuscitation. It is
recommended that if there are multiple victims
in a strike to treat the apparently dead first
since many can be revived. Strike victims can
suffer lifelong neurological problems.
Symptoms are problems with short-term
memory, problems sleeping, irritability,
attention span problems, chronic pain,
dizziness, chronic fatigue and personality

Lightning Safety Tips:
1. Get the i e/, Iher forecast ahead of going
outdoors. Try to plan activities around times
of exposure to hazardous weather.
2. If outdoors, identify a proper shelter and
stay i, i/hin range. Use the "30-30 Rule" to
know when to seek safety. The "30-30 Rule"-
When you see lightning count the time till you
hear thunder. If the time is 30 seconds or less,
go immediately to a safe shelter.
Remember if you hear thunder then
lightning is within striking range. After the
storm has moved on wait 30 minutes or more
after hearing the last thunder before leaving
safe shelter. The "30-30 Rule" protects against
storms moving into the area but does not
protect against the first lightning strike so
always be alert to the condition of the sky
overhead. Watch clouds to see if they are
increasing, thickening, and darkening,
especially if they develop a deep vertical extent
or if rain gets heavier and the wind stronger.
3. If lightning i/ eIuwien go to a safe shelter.
What is a safe shelter? The safest place is a
large, fully enclosed, substantially constructed
building. The wiring and plumbing in a
building such as a house or public building will
conduct the lightning safely to the ground.
When you are in the safe shelter stay
away from open windows and doorways; inner
rooms are considered safer. Do not use corded
phones, computers and video games. Hard-
wired phones are the leading cause of indoor
lightning strikes. Cell phones are safe to use.

Summer 2007

Berry/Vegetable Times

Stay away from electrical appliances,
lighting, electric sockets and plumbing.
If you can't take shelter in a
substantial building then an enclosed vehicle
with a solid metal roof and metal sides is a
good second choice. We have always heard
vehicles are safe because they have rubber
tires to insulate them but the correct reason is
the metal shell of the vehicle. Inside the
vehicle close the windows, lean away from
the door and don't touch the steering wheel,
ignition gear shift or radio- you want to
avoid any conducting pathways going
outside, and put your hands in your lap.
Convertibles, cars with fiberglass or plastic
body shells and open-framed vehicles are not
safe lightning shelters.
4. If you can not reach a safe shelter
minimize your risk of being struck. Avoid
all outdoor metal objects such as poles,
fences, gates, metal bleachers, mowing and
road machinery. Avoid solitary trees, water,
open fields, high ground or caves. Do not
remain in open vehicles, such as tractors,
riding lawnmowers or golf carts. Open
structures such as picnic pavilions, rain
shelters or bus stops are not safe shelters. Be
sure to remember not to get under a tree for
protection from the rain.
5. Ifyou are far from shelter and lightning is
occurring it usually gives a warning. Your
hair may stand on end, your skin will tingle
and light metal objects will vibrate and you
may hear a crackling or "kee-kee" sound.
These signs mean you are in the bolt's
electric field. Quickly remove metal objects
including baseball caps. If you are in a
group of people everyone needs to spread out
so there is at least 15 feet between each
person. Then go into the lightning crouch-
put your feet together, squat down, tuck your
head and cover your ears. When the
immediate threat has passed get to a safe
place as soon as possible.

6. If someone is struck they do not carry an
electrical charge and it is safe to begin first
aid immediately.

Lightning is the underrated storm-
related danger and we live, work and play in
the "lightning capital". Remember to pay
attention to the weather conditions and seek
safe shelter when necessary. For more

if I have to pay $4/lb for 50/50". In the final
analysis, we discovered it was not much of a
revolt and that chloropicrin was the cause.
Florida strawberry growers have never
particularly liked chloropicrin (pic). For
Florida growers (we won't implicate others)
there was justification for such disdain. As
long as methyl bromide was the near exclusive
constituent of the formulation, chloropicrin
was not needed for soilborne pest and disease
control. In fact, if you added too much pic to
the mix you could almost certainly count on a
few more weeds in the field to deal with after
fumigation. In addition to weeds, we also have
a fear that with a formulation of 50/50 we may
even see a few more nematodes survive the
treatment to become an unresolvable problem
during the season. Secondly, and probably as
important as the loss of pest control activity,
are the issues of worker complaints and
potential for off-site movement of a compound
alternatively identified as tear gas. Pic, unlike
methyl bromide, can be very unforgiving to
workers for sloppy application and fumigation
procedure. Finally, there is the dogma that
chloropicrin confers undesirable vegetative

farming growth at the expense of fruit
growth in strawberry. This is a plant growth
phenomenon which we have yet to
demonstrate in the field. In fact, it seems
ironic that all of the alternatives to methyl
bromide currently used in California, Florida
and other states of the southeast for
strawberry rely heavily on either chloropicrin
alone for its fungicidal activity, or for its
synergizing effect with 1,3-D (Telone) or
methyl iodide (Midas) for fungicidal,
nematicidal, and even added herbicidal
So with all of this said, 50/50 will be
the principal fumigant of choice this fall, but
realize that there are other choices that
should be considered for testing. If growers
are intent on using 50/50, they should really
consider a reduced rate (150 lb/A) under a
high barrier or VIF mulch film. We
recognize that the costs for a minimum 20-
25% reduced rate and use of the high barrier
are not off-setting. We believe that any
problems in field preparation, fumigant
calibration, delivery, and or containment will
only force growers to pay for the errors later
with reduced pest control efficacy and yield.
To us, it translates to 'you can pay for it now
or later, take your pick'.
This past spring we concluded the
season much the same way we have others,
with an extension grower meeting. This year
in addition to a discussion of Critical Use
Exemptions (CUE) for methyl bromide, we
focused on the current status of EPA re-
registration of the soil fumigants, particularly
that of chloropicrin. It was a lively, well
attended meeting, particularly after it was
reported that we were getting near the bitter
end to methyl bromide availability and that
EPA was proposing to implement
requirements for pretty substantial buffer
zones surrounding fumigant treated fields.
We proceeded to indicate that due to changes
in personal protective equipment (PPE) and
buffer zone requirements anticipated with

EPA fumigant reregistration, our field
research focus had shifted towards evaluations
and recommendations of pre-bed applications
rather than in-bed or broadcast fumigant
treatments. We indicated that the best
available alternative for strawberry is
currently Telone C-35 (1,3-Dichloropropene +
35% chloropicrin), applied pre-bed at 22 to 35
gallons per treated acre, 3-5 weeks ahead of
scheduled transplanting (Table 1). We
indicated that to avoid the requirement for use
of half face respirators, Telone C-35 had to be
injected to flat soil just prior to any soil
mounding or bed-forming operation (pre-bed)
to a depth of at least 12 inches. In
combination with pre-bed Telone C-35, we
recommend use of only a high barrier or
virtually impermeable mulch film (VIF). With
use of the impermeable mulches, fumigant
rates can be reduced 25 to 40% from
maximum labeled broadcast application rates
as a starting point for evaluation. In addition
to the Telone C-35, a herbicide tank mix of
Goal (oxyfluorfen) (0.5 pounds) plus Devrinol
(napropamide) (4 pounds) per treated acre,
applied to the raised bed surface at plastic
laying would overcome the weed control
limitation of the fumigant. Also remember
that use of Goal requires a minimum 30-day
pre-plant interval before transplanting.
In addition to pre-bed Telone C-35,
there are other fumigant options which we
believe growers should be considering for
field evaluation during Fall 2007, particularly
where sting nematode is a recurring problem.
In these situations, a late summer broadcast
treatment with Telone II (12-18 gal/A) should
be considered in advance of a pre-bed
treatment with chloropicrin alone or with
Telone C-35. With 2 drip tapes per bed,
chemigational uses of the alternative
fumigants should also be considered as
potential alternatives to methyl bromide,
particularly for minimizing PPE and future
buffer zone requirements. Conducting the
fumigation after the plastic is laid and

irrigation is operational puts the majority of
workers out of the field and the fumigant
under the plastic. Based on our previous
injection dye work, we know that use of two
tapes per bed will provide near complete
distribution and coverage of the fumigant in
the bed, but just as important, will also
confer significant benefit to plant growth
through improved plant nutrition and
moisture availability to twin rows of
strawberry and then to any crops which
follow. If there were a 'Best buy' or 'blue
light special' to be had, this strategy is it.
We realize that human nature
prevents us from assuming too much risk,
from treading too far into the unknown and
unfamiliar. At some point however, these
giant steps will have to be taken, particularly
when we've shown the risks to be minimal.
At some point we will have to accept the use

of the high barrier mulches as standard
operating procedure and the sooner we begin
the evaluation of the alternative fumigants the
better off we will be. Methyl bromide price
and continued availability has been both a
blessing and impediment to Florida growers
who continue to be reluctant to transition to
the new integrated pest management
strategies. We don't believe the attitude and
response to suggested change should be "I
will quit farming" before I do this or do that.
As altruists, we are afraid that Florida
strawberry farmers will be forced to quit
farming if they don't start the investment, i.e.,
planning and implementing their own on-farm
transition strategies and timetables. The
learning curve can be steep, and we don't
think growers can wait until the bitter end and
pull it off flawlessly.

What is Geomatics?
Amr Abd-Elrahman, Assistant Professor of
Geomatics-GCREC Plant City

Geomatics is .
defined in the Oxford
English Dictionary as
"the mathematics of the
earth; the science of the
collection, analysis, and V. 4
interpretation of data, r -.
especially instrumental
data, relating to the
earth's surface".
Geomatics helped the
development of many
evolving technologies that strongly touch our
daily life. When we talk Geomatics we can
talk about navigation and positioning using
GPS equipment; Google Earth mapping
through satellite and aerial images, and county
land records via Geographic Information
Systems (GIS), etc.
Advancements in the field of
Precision Agriculture are strongly linked to
recent development in the Geomatics field.
For example, autonomous navigation of
equipment, such as farm tractors, is only
facilitated by GPS technology. Plant behavior
with different soil management and
fertilization techniques can be imaged,
monitored, and managed. Plant diseases can
be detected early through imaging with
different sensors utilizing a wide range of
infrared energy. With tens of billions of
dollars spent by the agriculture industry in soil
treatment, fertilizing, and fighting plant
diseases, it leaves no doubt that the
integration of Geomatics technology and
expertise in the Precision Agriculture field,
which has long way to go, shall be of a great
mutual benefit to both fields.

Using Preplant Starter Fertilizer
with 'Strawberry Festival'
Bielinski M. Santos, Horticulturist

Nitrogen (N) is the most absorbed
plant nutrient on per weight basis in most
vegetable crops. This nutrient is an essential
component of basic structures in all plant spe-
cies and its deficiency can severely affect
growth and development. Most of the N is
absorbed through plant roots in the form of
the ion nitrate (NO3-) dissolved in the solu-
tion. In soils with low organic matter content,
such as the sandy soils throughout Florida,
natural N supply is low and supplemental fer-
tilization is required to cover the crop demand
of this essential nutrient. In strawberry pro-
duction, this is achieved in two ways: a)
through application during the growing season
of all N through drip lines (fertigation), or b) a
combination of this practice and the applica-
tion of dry preplant starter N before bed for-
Recent surveys showed that about one-
half of strawberry growers apply preplant fer-
tilizer formulas that include N. Application
rates usually ranged between 20 and 40 lb/
acre of N. Environmental concerns over
leaching nitrates to Florida ground waters has
brought to the forefront the necessity of con-
ducting research on best management prac-
tices that could reduce the use of starter fertil-
izers in production systems where fertigation
is available, such as in strawberry fields.
Therefore, studies were conducted to deter-
mine whether using preplant starter N fertili-
zation increases strawberry early and total
Field studies were conducted at the
Gulf Coast Research and Education Center,
IFAS, University of Florida. 'Strawberry Fes-
tival' bare-root transplants from Canadian
nurseries were transplanted in the first week
in October of each year. Plant nutrients, other
than N, were applied through drip lines ac-
cording to IFAS recommendations to ensure

non-limiting conditions. Calcium nitrate was
used as the starter fertilizer at a rate of 40 lb/
acre ofN. A non-treated control was also in-
cluded. The fertilizer was broadcast incorpo-
rated 4 inches deep on bed tops before final
bed pressing. Afterwards, beds were fumi-
gated and covered with black high-density
polyethylene mulch immediately after fumi-
gant injection. Simultaneously, a single drip
line was buried on bed centers. Strawberries
were grown following recommended local
The results showed that applying
starter N fertilizer did not improve monthly
or total strawberry yield (Figure 1). This in-
dicated that growers can avoid using preplant
starter N fertilizer and still obtain the same
yields, provided that appropriate fertigation
rates are used to ensure satisfactory crop
growth and development.

Your Skin in the Sun
From Safety Stuff no. 346 March 28, 2007-
Richard Hawk

"Beauty's but skin deep," observed a poet of
Elizabethan times--a depth, actually, of only a
few millimeters. This thin, elastic covering
gloves the body from scalp to sole, giving color
and character to the human form. Of all the
body's tissues, none is more exposed to disease
and injury than the skin.

Here are a few tips and trivia about this wonder-
ful (but often abused) organ:

* Skin cancer is the most common form of
cancer. Ultraviolet light is its leading cause.
People of northern European descent, having
the least amounts of melanin, are most
prone. Ireland, with a fair- skinned popula-
tion, has one of the world's highest rates of
skin cancer, even though it does not receive
especially high amounts of ultraviolet light.
Basically, the darker your skin is naturally,
the less likely you are to get skin cancer.
* It is ironic that tanned skin is associated with
a youthful, healthy look. Steady tanning can
lead to premature wrinkles, sags and discol-
* Sun damage is cumulative and irreversible.
Once the skin is so affected, no amount of
facials or moisturizers can reverse the dam-
age, which usually does not show up until
later in life.
* You might be getting only half as much skin
protection from your sunscreen lotion as you
think. The thickness of the sunscreen layer
on your skin is the key to getting the sun
protection promised on the bottle. In a clini-
cal study, 50 people applied a variety of
brands of sunscreen the way they normally
would. Scientists added fluorescent coloring
to the sunscreens so the thickness could be
measured. Most of the sunscreen-users
rubbed on their lotion only half as thick as
the recommended thicknesses.

Berry/Vegetable Times

* Scars have less pigment than the rest of
your skin, so they're especially
vulnerable to sunburn--and prolonged
redness. You should make certain to
cover all exposed scars with a sunscreen
with an SPF of 25 or higher.
* A simple, moderately severe sunburn
damages the blood vessels to such an
extent that it takes four to fifteen months
for them to return to their normal
* The most effective sunscreens contain
the chemical agent paraaminobenzoic
acid, PABA, which duplicates the action
of melanin by absorbing ultraviolet rays.
Products such as baby oil and coconut
butter do not protect the skin from
burning at all.
* In the United States, more than 500,000
new cases of skin cancer are found each
year. This is why one in seven
Americans can expect to get skin cancer.
* Some diuretics, antibiotics, tranquilizers,
birth control pills and diabetes
medications can add more salt to your
sun-burn wounds. They can make you
sun- sensitive. So can some medicated
soaps, perfumes and "wrinkle
removers". So if you use any of these
medications or products, doctors advise
you to take extra precautions when
exposing your skin to the sun.
* In only one square inch of human skin
there are 19 million cells, 625 sweat
glands, 90 oil glands, 65 hairs, 19 feet of
blood vessels, 19,000 sensory cells, and
over 20 million microscopic animals.

An unusually durable fungus that was first
spotted on tiny insets feeding on eggplants in
Texas may be come a new biological control
for the widespread and costly whitefly. The
fungus was first isolated by USDA
Agricultural Research Service (ARS)
entomologists at the ARS Beneficial Insects
Research Unit, Weslaco, Texas. The new
fungal species has been names Isaria
propawskii. In the lower Rio Grande Valley of
Texas, it has been shown to kill both larval and
adult stages of silverleaf whitefly. In fact,
since 2001, it has periodically wiped out
whiteflies at the ARS insect-rearing facilities
in Weslaco. Notable aspects ofL. propawskii
include its natural establishment in a semiarid
region where temperatures can reach 107
degrees Fahrenheit and its continuing
persistence, even in the absence of insect hosts.
A high spore production in common culture
media makes this fungus comparatively easy to
grow in vitro in the laboratory. These features,
plus its high pathogenic potential against a
second major insect pest-the glassy-winged
sharpshooter, Homalodisca vitripennis-make
the fungus a promising candidate for practical
biological control of two major U.S. farm
pests. (ARS News, 5/11/07).
