What the Public Needs
to know about Protecting
Strawberries from
Freeze Damage
Craig Chandler and Vance Whitaker

As you talk to people
about strawberry freeze protection, here are
some facts you may want to keep in mind:
Understanding that this was an
extremely rare January can be of great help to
the public. Typically, there are no more than a
few freezes each winter in the Plant City/
Dover area, and these are often of short
duration (3-4 hours or less). A period of 9
days in which the minimum daily air
temperature is below 32 F and the maximum
air temperature is < 60 F, as was the case
during the first half of January this year, is a
once in a lifetime occurrence. According to
FAWN, the weather station at Dover typically
experiences a total of 96 hours below 45 F in
January. This year it was 264 hours.
When a freeze is the result of clear
skies and calm conditions, sprinkler irrigation
is an efficient and cost effective method to
protect strawberry flowers and fruit. Eighty
calories of energy (in the form of heat) are
generated for each gram of water that freezes.
This heat can keep plants at 32 F, but water
has to be applied continuously and in sufficient
quantities.
Newspaper and TV reporters often state
that a coating or blanket of ice insulates
flowers and fruit, protecting them from air
temperatures below 32 F. To the casual
viewer or reader this sounds like a logical
explanation, but if it were true sprinkler
systems could just be run until the plants were
covered with ice and then turned off. What
protects strawberry flowers and fruit is the heat
of the liquid water (which comes out of the
ground at about 72 F) and the heat that is
generated as the irrigation water changes from
liquid to solid (a chemical property known as
the heat of fusion).









Damage to strawberry flowers and
fruit can start to occur when tissue
temperature reaches 30 OF. A period of very
warm weather preceding the freeze may
result in tissue being damaged at a higher
temperature. Conversely, a period of cold
weather preceding the freeze may condition
tissue such that it can withstand temperatures
below 30 OF before damage occurs.
When there is little or no wind,
sprinkler systems will generally not be
turned on until the air temperature is 31 OF.
However, when an advective (windy) freeze
is expected, it is common to turn the
sprinkler system on when the air temperature
is 34 OF. This is because the temperature of
wet plant tissue exposed to wind will initially
drop due to evaporative cooling. Then as
water begins to freeze, the heat of fusion will
counteract the heat loss due to evaporation
and the temperature will stabilize at about 32
OF.
Wind can result in evaporative
cooling that lowers tissue temperatures 5-6
F below the air temperature. This is why, if
it's windy, the air temperature may need to
be 36 OF or higher before it is safe to turn off
the sprinklers.


Reporting Freeze Protection
Pumpage to the Water District
Ron Cohen, P.E., Agricultural and Irrigation Engineer
Southwest Florida Water Management District

Ron. Cohen@Watermatters.org

Besides being a requirement of a
water use permit, reporting cold protection
pumpage is needed to help avoid potential
compliance issues and to ensure that a
permitted's conservation credits are
calculated correctly. Cold protection amounts
are not limited by a permit's annual average
allocation. However, the cold protection


amounts need to be reported so that they can
be subtracted from the submitted pumpage
quantity. If a permitted does not report the use
of irrigation for cold protection this could
make it appear that the permitted overpumped
the permitted quantity and cause the District's
computer system to flag the reported high
water use as a permit violation.
Reporting cold protection water use
also ensures that a permitted receives all the
SWUCA conservation credits they have
earned. The cold protection pumpage report is
used by the District to ensure that conservation
credits are not deducted for this important use
of irrigation for crop protection.
Copies of the form can be found on the
District's web site at: http://
www.swfwmd.state.fl.us/permits/wup/ The
District realizes that the producers are busy
with their crops, but it will be in their own best
interest to follow through with this
information. If they can get the reports to the
District the same time they report their
monthly meter readings it will help both the
growers and the District.


Battling Botrytis Fruit Rot
Jim Mertely and Natalia Peres

Strawberry losses to plant diseases
may be high this season due to the increased
cloud cover, higher relative humidity, and
frequent rains associated with an El Nino
winter. Angular leaf spot (ALS) has already
caused problems. An article on ALS appeared
in Berry Vegetable Times last March and can
be found on the internet at http://
strawberry.ifas.ufl.edu/BVT0309.pdf Botrytis
fruit rot is another disease favored by El Nino
conditions, and we are now entering the peak
bloom period when the battle against Botrytis
can be won or lost.
Botrytis fruit rot (BFR) or "gray mold"
is a disease caused by Botrytis cinerea. This
fungus usually attacks flowers and fruit,









although transplants stored in the cooler for
too long may also be damaged. Fruit
developing BFR are often infected as
flowers. That's why it is so important to
apply fungicides for Botrytis during the
flowering period. Some of our berry fields
have already entered the main flowering
period or will do so very soon. Infected
flowers develop into visibly diseased fruit
within two to four weeks (Photo 1). By then,
it can be too late to apply effective control
measures. The time for effective
management of BFR is now, during the
bloom period.


S

Conventional wisdom says to begin
spraying for Botrytis at the start of the main
flowering period (i.e., at 10% bloom).
Depending on the cultivar and season, 10%
bloom usually occurs between mid- to late
January. Applications are made weekly for
three to four weeks to protect the majority of
flowers that open during the bloom period.
Another approach would be to target the
applications to periods when flowers are
most likely to be infected, that is, when the
weather is wet and temperatures are cool to
mild. A grower once remarked that he
sprays periodically when dew starts dripping
off the metal roof of his tool shed before he
goes to sleep. This is a very perceptive
statement since how long the leaves and
flowers remain wet is one of the most


important factors in modeling and predicting
Botrytis diseases. An internet-based system to
help strawberry growers decide when to spray
for BFR is available at http://
www.agroclimate.org. Locate "Agroclimate
tools" on the main menu and click on
"Strawberry disease tool" to start the program,
then on the weather station icon closest to your
field to begin. Growers can also sign up to
receive e-mail or cell phone text messages
(SMS) alerts when disease risk reaches
moderate or high levels. If you are interested,
please contact Dr. Natalia Peres
(nperes@ufl.edu).
After the decision is made to spray for
Botrytis, the next decision involves fungicide
selection. Standard protectant fungicides such
as Captan (or Captec) and Thiram are both
suppressive to Botrytis, but by themselves,
neither is adequate when weather conditions
favor the disease. When these conditions
prevail, products with good activity against
Botrytis should be applied, either alone or tank
mixed with a protectant fungicide. Products
that can be applied alone include Captevate (a
premix of captain and fenhexamid), Pristine (a
premix of pyraclostrobin and boscalid), and
Switch (a premix of cyprodinil and
fludioxonil). In some areas, Botrytis has
developed resistance to boscalid, so the effects
of Pristine should be monitored closely.
Elevate (fenhexamid) and Scala (pyrimethanil)
are usually tank mixed with protectant
fungicides. By using mixtures of different
fungicides, other diseases which flare up
during the bloom period (e.g., anthracnose fruit
rot) are also suppressed.
If flowers are adequately protected
during the main bloom period, BRF is
minimized, usually for the remainder of the
season. Fruit losses can be further reduced by
good harvest practices such as plant sanitation.
Pickers should be encouraged to pick and
throw down newly infected fruit, as well as
fruit mummified by Botrytis (Photo 2). Plant
sanitation will reduce spore production, but










more importantly, will minimize the amount
of infected material left in the plant canopy.
This reduces the spread of BFR from
diseased fruit or infected fruit stalks to
healthy fruit by direct contact (Photo 3).
Additional information on Botrytis
Fruit Rot is available on the University of
Florida's EDIS website http://
edis.ifas.ufl.edu/ppl 52.

Notes on Cultural Practices: Can
High Tunnels Reduce Water
Volumes for Freeze Protection and
Improve Strawberry Yields at the
Same Time?
Bielinski M. Santos and Teresa P. Salamd-Donoso

1. What is the Difference between Tunnels
and Greenhouses?
There are two main production systems
for strawberry throughout the world: Open-
field and protected culture. Protected culture
includes structures such as greenhouses, high
tunnels, and mini-tunnels. A greenhouse is a
permanent structure (e.g. set on concrete on the
ground) with a glass or plastic roof and walls
and in most cases possesses heating and
cooling systems. This characteristic can be
beneficial for winter season production and for
crops that need warm temperatures. Crops
inside greenhouses are mostly produced in
growing media or soilless culture. Structures
range in size from small sheds to very large
buildings. Greenhouses could be set up for
production, with computer-controlled screens,
lights, and heating and cooling systems.
High tunnels are temporary, unheated,
plastic covered, solar structures, with passive
ventilation through roll-up side walls (Picture
1). These are secured with metal or wooden
poles on the ground, similar to a giant
backyard tent. Their height might vary from 5
to 20 ft. Crops are usually grown in soil
(Picture 2). However, pot, bag and sack culture
could be used, along with various growing
media (e.g. peat, perlite and vermiculite)
depending on availability, prices, and crops.
Mini-tunnels or low tunnels are made of
galvanized iron or steel bars at a height of
about 50 cm from the plants, which are grown
on raised beds. Mini-tunnels are covered with
clear plastic during cold weather or rain.

ries growing on mulched beds in high

Strawberry production under protected structures might not need the use of sprinkler
irrigation for freeze protection. Some of the potential benefits of growing strawberries in
protective structures, such as high tunnels, are improved yield and fruit quality, reduced
incidence of insect populations, weed interference, and protection from rain damage. In
addition, high tunnels could diminish the adverse effects of cold weather on late fall and winter
production.
2. Effects of Tunnels on Water Use for Freeze Protection and Yields.
2.1. Procedures. In spite of the popular use of high tunnels and protected agriculture in
countries such as China, Spain, and Japan, it was still necessary to investigate their effects on
Florida strawberry production, due to the differences in climate, cultivars, and production
systems. Therefore, research was conducted to compare the effects of high tunnel and open-
field production on the growth, fruit earliness and yield of strawberry cultivars. Studies were
conducted during two years at the Gulf Coast Research and Education Center of the University
of Florida, Balm, Florida. The soil was fumigated with methyl bromide + chloropicrin (67:33 v/
v) and the beds were covered with black high-density polyethylene mulch. Fertigation was
applied through a single drip tape line delivering 0.23 gal/100 ft/min. The experimental area










was equipped with 4 gal/min sprinklers for
frost protection and crop establishment. The
tested cultivars were Strawberry Festival,
Winter Dawn, and Florida Elyana. The high
tunnels were 16 ft high, 25 ft wide and 280 ft
long, and covered with a single layer of clear
polyethylene film that reduced active solar
radiation by 30% (Picture 3). For freeze
protection, the ends and sides of the units
were covered 24 h before the forecast freezing
with a single layer of the same film used on
the high tunnel roofs. The units were
ventilated by lowering the sides and ends of
each unit as soon as the air temperature
reached 500F, provided that another freezing
event was not forecast for the following night.
Air temperature data loggers were placed 8
inches above bed tops inside and outside the
high tunnels and recorded maximum and
minimum temperatures each hour during the
growing seasons. Bare-root strawberry
transplants from Canadian nurseries were
planted on 15 Oct. of each year, in double
rows 15 inches apart between plants.
Immediately after transplanting, overhead
irrigation was used for 8 h for the first 10 d to
ensure plant establishment. Marketable fruit
yield was collected twice per week for a total
of thirty harvests during each season. Early


and total yield were considered the total
marketable fruit weight from the first six
harvests, and from all thirty harvests,
respectively.
2.2. Early and Total Yields. Production
systems and cultivars affected strawberry early
and total yields. During both seasons, early
yields were 54% and 16% higher inside high
tunnels than in open fields (Table 1).
'Strawberry Festival' had the highest early
yield with 2.2 and 3.2 ton/acre during the 2007
-08 and 2008-09 seasons, respectively,
followed by 'Winter Dawn' and 'Florida
Elyana'. Strawberry total marketable yields
maximized inside high tunnels in comparison
with open fields, with 63% and 50%
increments during both seasons. Among the
cultivars, Strawberry Festival produced the
highest total marketable yields, followed by
Winter Dawn and Florida Elyana. These
findings indicated that the protective
environment improved strawberry fruit
earliness and total yield under Florida
conditions.
2.3. Freeze Protection. Both growing
seasons had different temperature patterns
from October to March of each year. In 2007-
08, there was a single freeze in the early hours
of 3 Jan. 2008 and the air temperature outside

the high tunnels was as low as 270F, whereas
the air temperature at the same time inside
the high tunnels was 340F. In the 2008-09
season, there were three freezes during this
season; from 21 to 23 Jan., and 5 and 21 Feb.
2009. The minimum air temperatures outside
the high tunnels were 27, 21, and 23 F (from
21 to 23 Jan.), 270F (5 Feb.), and 30oF (21
Feb.), whereas the lowest minimum air
temperature inside the high tunnels was 34F
during all these freezing events. No sprinkler
irrigation for freeze protection was necessary
inside the high tunnels.

3. Summary.
These results showed that planting
strawberry cultivars under high tunnels has a
major influence on the growth and
development of strawberry. Using high
tunnels led to improved early and total
marketable yields by 29% and 56%,
respectively, across all the tested cultivars.
Furthermore, the marketable yields of the
next six harvests after freezing increased by
75% and 64% in the 2007-08 and 2008-09
seasons, respectively (data not shown).
Several environmental factors likely
influenced these responses:
a) High tunnels protected flowers and small
fruit against the effects of hard freezes during
both seasons;
b) Flowers and fruit were not exposed to
sprinkler irrigation damage during freeze
because it was not necessary inside the high
tunnels to protect the crop;
c) High tunnels protected fruit against
rainfall, which causes reduced fruit number
and quality.
Although a detailed economic
analysis is needed, the use of high tunnels in
Florida for strawberry production might
benefit growers by improving earliness and
providing a competitive edge in the market.
Also, using high tunnels may open these
opportunities for Florida strawberry growers:
a) Minimal use of sprinkler irrigation for


freeze protection, hence reducing fruit damage
and fuel or electricity costs of water pumping;
b) Decreased incidence of foliar and fruit
diseases, which are disseminated by rain drops,
leading to less fungicide applications;
c) Opportunity for alternative production
systems, such as intense intercropping and
soilless culture to reduce fumigation practices.
Conditions prevailing on individual
farms should influence growers' interest in this
alternative production system. Care should be
exercised to avoid broad generalizations of the
suitability of these protective structures.


Rimon Novaluron Approved in
Florida for Sap Beetles
James F. Price

U.S. EPA has approved Florida
strawberry growers' use of Rimon novaluron
for the control of sap beetles now through 31
December 2010 by the Section 18 specific
exemption process. Rimon may be applied at
the rate of 12 fluid ounces of product per acre
up to three applications.
Rimon does not kill adults, but is very
effective in preventing the occurrence of larvae
in the field and reproduction of sap beetles
within the treated area. UF GCREC research
sponsored in part by FSGA has determined
that Rimon is effective when applications are
separated by 3 weeks.
Rimon is provided by Chemtura
Corporation. Chemtura, FFVA, FSGA, and
UF cooperated in securing the use of Rimon
for Florida strawberries.

Spotted Wing Drosophila is Widely
Distributed in Our Region of Florida
James F. Price

FDACS fruit fly investigators now have found
spotted wing drosophila, pest of ripe
strawberry, blueberry, raspberry, and
blackberry fruit, in most counties from Lake in









the north to Collier in the south and in a band
across the state from Pinellas to Indian River
counties. The fly should be considered
generally distributed within this area and
likely to expand its range soon well beyond
these counties.



S Farmers should make
-3'1 a skin check a priority

low LV Farming has plenty of
Challenges, but probably one
of the hazards that farmers
worry about the least are the dangers from
working in the sun year-round. As the
harvest concludes and winter sets in, farmers
should pay attention to the condition of their
skin.
"More than 11,000 Americans die
each year from skin cancer," says Dr. David
M. Pariser, a dermatologist and president of
the American Academy of Dermatology.
"But when detected early, skin cancer has a
cure rate of 99 percent. Since research shows
farmers are among the least likely workers to
receive a skin examination by a physician,
it's important that farmers perform regular
skin self-examinations, which could mean
the difference between life and death."
It's as easy as "ABC" to remember
how you can identify a mole or lesion that
needs the attention of a dermatologist:
Asymmetry (one half is unlike the other);
Border (irregular, scalloped or poorly
defined); Color (varies from one area to
another); Diameter (the size of a pencil
eraser or larger); Evolving (changing in size,
shape or color).
To help farmers minimize their risk
of skin cancer, the American Academy of
Dermatology recommends that everyone Be
Sun Smart:
* Use water-resistant sunscreen with a sun
protection factor (SPF) of at least 30 on all


exposed skin, before heading out to the field
or pasture. Re-apply approximately every two
hours, even on cloudy days.
* Wear long-sleeved shirts, pants, a wide-
brimmed hat and sunglasses.
* Stay in the shade when possible, and make
sure your tractor has a sun umbrella. The sun's
rays are strongest between 10 a.m. and 4 p.m.
* If working near water, snow or sand, seek
extra shade because these surfaces reflect the
sun's rays and increase your chance of
sunburn.
* Look at your skin after each harvest. Ask a
partner to help. If you notice any moles or
spots changing, growing or bleeding, make an
appointment to see a dermatologist.

The Academy offers a downloadable
Body Mole Map with information on how to
perform a skin exam and images of the
ABCDEs of melanoma. The mole map is
available at www.aad.org/checkspot. The site
also has information on how to find a free
cancer screening from a dermatologist in your
area.
Performing a skin self-exam requires
regularly looking over the entire body,
including the back, scalp, soles of the feet and
between the toes, and on the palms. It is
important to use both a full-length mirror and
a hand-held mirror to see the scalp, back and
buttocks.

Registrants to Lose Inerts
Exemption
The U.S. Environmental Protection
Agency announced before Christmas that it
plans to require pesticide manufacturers to
disclose to the public the inert ingredients in
their products. An inert ingredient is anything
added to a pesticide that does not kill or control
a pest. Nearly 4,000 inerts including several










hundred that are considered hazardous under
other federal rules are used in agricultural and
residential pesticides.
The EPA's announcement that it will
initiate the rulemaking comes 11 years after it
had first been petitioned by activist groups and
state officials seeking public disclosure of the
ingredients. In 2001, the agency denied those
petitions filed by ten state attorney generals
and an activist coalition, and its decision was
upheld by a federal judge in 2004.
Now, under a new administration, the EPA has
decided that drafting a new regulation will
"increase transparency" and help protect public
health. "EPA believes disclosure of inert
ingredients on product labels is important to
consumers who want to be aware of all
potentially toxic chemicals, both active and
inert ingredients, in pesticide products,"
according to the agency's website.
Formaldehyde, bisphenol A, sulfuric
acid, toluene, benzene and styrene are among
the ingredients that are allowed in pesticides
but are not identified on labels. Some are
carcinogens, while some may cause
reproductive or respiratory problems if people
are exposed. Other inerts seem benign, such as
coffee grounds, sunflower oil and licorice
extract. One goal of the planned rule is that
pesticide companies would be more likely to
replace toxic chemicals if they must identify all
ingredients on their labels. "By embarking on
such rulemaking, EPA intends to effect a sea
change in how inert ingredient information is
made available to the public," Debra Edwards,
the EPA's director of pesticide programs, said
in a September letter to the Northwest
Coalition for Alternatives to Pesticides,
California Attorney General Edmund G.
Brown, Jr. and other petitioners.
Edwards wrote that the EPA will seek
"a significant amount of input" from
stakeholders as they craft the new rule
"because of the magnitude of the change and
the difficult issues facing the agency" Under
current law, pesticide companies already
disclose all ingredients to the EPA. The new
rule would make them public.


Jay Vroom, chief executive officer of
CropLife America, which represents pesticide
manufacturers, said that the registrants are
concerned they will be revealing confidential
business information, or trade secrets, about their
formulas. Vroom said it was "just baffling" that
EPA will draft a rule when the pesticide products
already undergo risk assessments and are
approved for use. He said EPA officials are using
"unbridled rhetoric" when addressing the issue of
inerts.
"We believe these products already have
been regulated to protect public health," he said.
"What is confusing is why the agency has been
out talking about these products as hazardous
inert ingredients. To me, that's an oxymoron."
Vroom said the industry will work with the EPA
but that no timetable for stakeholder meetings
has emerged yet. Options the EPA said it will
consider include disclosure of all inert
ingredients regardless of hazard or only those
that are considered potentially hazardous. Some
of the requirements may be voluntary.
