From Your Agent...
A Question on Notifying Workers for WPS

A question has been asked about notifying workers of
a treated area- Can you post the treated area because you feel
it better informs your workers of the area that has been treated
even if the label does not call for posting- only for orally
warning workers?
The answer is yes you can post signs around the
treated area even if the label says only oral warnings need to
be given. If the label requires oral and posted notification you
will have to do both methods. It always is a good plan to tell
your workers where the treated area is and to obey the signs
that are posted. If you are going to post treated areas as the
main method to communicate to workers what areas have
been treated it is a good idea at the beginning of the season or
when you start using posting to tell them which method of

The Season in Review: Testing and Transition to
Methyl Bromide Alternatives

In our last newsletter article, as we have in many
previous, we talked about the phase-out of methyl bromide.
We discussed Critical Use Exemptions (CUE) and how the
amount of new production of methyl bromide is reduced each
year and how the price and formulations with chloropicrin are
changing to reflect scarcity. So again in this regard, there have
been new developments. For example, the price of methyl
bromide has increased again to $3.75 lb for a formulation of
67/33 as of January 1, 2007. Assuming a 200 lb per acre rate,
this now equates to a treatment cost of $750 per acre. With an

increase in price, the manufacturers and
distributors also are promoting the sale of
only a 50/50 formulation of methyl bromide
and chloropicrin to growers. Clearly, things
are not the same, and with the increased
chloropicrin content, we can expect a loss of
overall weed control, particularly of tough to
kill weeds like nutsedge.
In addition to a cost increase from last
year, there were instances of statewide
shortages of CUE stocks of methyl bromide
reported in November 2006. Growers who
wanted to use methyl bromide to lay plastic in
November were forced to wait to purchase
2007 CUE stocks of methyl bromide in
January. This was the first evidence we are
aware of where supply could not satisfy
demand, and there is no reason not to expect
similar scenarios to reoccur in the future. In
some agricultural areas of the southeast,
current methyl bromide pricing is finally
exceeding what growers are willing to pay,
and broader trialing and implementation of
alternatives is finally beginning. In Georgia
for example, vegetable growers are fairly
widely trialing Telone, Chloropicrin, and
Vapam. With new application equipment,
Vapam is being shallowly applied through a
series of minicoulters to the surface of a
preformed bed (Figure 1). We think growers
should consider the above fumigant
combinations and application procedures in
planning for the fall fumigation season, to not
only purchase early but to seriously begin the
trial of alternatives to replace methyl bromide.
We hope to receive a federal grant which will
allow us to field test and demonstrate the
performance of various methyl bromide
alternatives on 40 farms this coming year.
This past fall we also learned that
methyl iodide, as a 50% formulation with
chloropicrin, would be initially priced at $10
per pound, using a corporate recommended
rate of 150 to 175 pounds per treated acre
under high barrier, gas impermeable plastic
mulch. Arysta Life Science, the manufacturer


of Midas" received a nationwide experimental
use permit (EUP) for field testing of the new
fumigant without requirement for crop
destruction. The EUP expires in August or
September and the company is hoping for
federal registration sometime in Fall 2007.
To view the performance of Midas, using
different rates and numbers of injection
knives or shanks, growers are encouraged to
view the research plots at the FSGA research
farm in Dover before seasons end. Plots are
identified by signs to facilitate self-guided
tours. We also need to express our gratitude
to John Stickles and George and Jaime Garcia
for a separate but duplicate Midas test, and to
Ronnie and Adam Young (Figure 2) for all
their hard work in putting out the FSGA
research trials. Industry support and
community service like this should not go
unnoticed or unrewarded.
This past season, with product
donations from Dennis Sutton of Pliant
Corporation, and funds from a USDA
CSREES grant, 80 rolls of a high barrier,
methyl bromide impermeable plastic mulch
film (Pliant BLOCKADE) were distributed to
20 individual Plant City Dover strawberry
growers. Most growers received 2 to 4 rolls of
the plastic mulch. In return and as a
stipulation of the gift, growers were required
to reduce their methyl bromide application
rate by 25 to 75% with the high barrier
BLOCKADE mulch. Unfortunately, not all
did. For those who did, we appreciate your
participation in the demonstration trials. As
we approach the end of the season, we will
conduct formal exit surveys of these fields
and ask growers to personally rate any
differences in crop growth, strawberry yield,
or pest control efficacy that occurred with the
different mulch and fumigant rate treatments
used in the field. We will report these
findings in a future issue of the newsletter.
Preliminary observations do seem to indicate
no problems with installation, in fact many

growers thought the BLOCKADE looked and
laid better than their standard. There was also
no reduction of growth or pest control when
methyl bromide rates were reduced by as
much as 50 percent with use of the
BLOCKADE film. Currently the roll price
of these high barrier plastic mulch films is
about twice that of the standard 1 mil
polyethylene mulch. But when you can't get
all the gas you need or can't afford the price
of gas, this is surely a way to resolve cost
savings with methyl bromide rate reductions.
Growers might also want to get used to the
idea of the high barrier mulch because EPA
reregistration of the alternative fumigants
chloropicrinn, Vapam, Kpam), will ultimately
demand use of these films to reduce buffer
zone requirements to tolerable levels. More
about this in the future as the EPA
reregistration process continues. Be prepared:

notification will be used on your farm.
Remember when using posting place the signs
at all points that workers will be using to enter
the area. Even though you are posting for a
label that only requires an oral warning you
will still need to observe the timing
restrictions on having the signs up. Signs can
be posted no earlier than 24 hours before the
scheduled application and are to stay up
during application and for the entire
restricted-entry interval (REI). Signs are to
stay up no longer than 3 days after the end of
the REI and if there is no REI they are to stay
up no longer than 3 days after the end of the
application.
Workers are to stay out of the treated
area while signs are posted unless they are
trained and equipped with personal protection
equipment for early-entry. Be sure your signs
are in good condition and legible.

Temperature pattern in west cen-
tral Florida this winter has likely
been a significant factor in the de-
velopment of fruit quality prob-
lems
Steve MacKenzie and Craig Chandler

Although normal temperatures oc-
curred in October and most of November,
average daily temperatures from approxi-
mately November 26th to January 23rd were
consistently 5 to 10 degrees Fahrenheit
higher than what would be expected for
this time of year (Figure 1). Also, unlike
what normally occurs in December and
January, the directional trend of the tem-
perature over time was actually flat or ris-
ing as opposed to declining. One effect of
the flattened or increasing temperature
trend was higher then normal early season
yields.
During much of December and
early January, favorable temperatures
(around 70 degrees) coupled with extended
leaf wetness periods, created ideal condi-
tions for grey mold infections to take place.
Because the grey mold pathogen, Botrytis
cinerea, infects fruit at flowering,
infections in December and January were

responsible for considerably high levels of grey
mold in late January and early February. Growers
also reported high levels of misshapen fruit in late
January and early February. High temperatures in
late December and early January, when these fruit
were flowers, may have contributed to the high
incidence of misshapen fruit. However, the tem-
peratures during this period were not outside of
the range seen during flower and fruit develop-
ment in late November and early December in
typical years.
Two other possibilities might explain the
misshapen fruit. During January conditions were
very conducive for development of powdery mil-
dew, and disease symptoms were especially bad
in the later half of the month and into early Febru-
ary. In GCREC trials it appeared that there was a
higher proportion of fruit that were misshapen in
plots that had a higher incidence of powdery mil-
dew. Also, fruit harvested during this period
tended to be tail end fruit, which precede the rip-
ening of primary fruit from the main crop. Typi-
cally, tail end fruit are smaller and of poorer qual-
ity. The gap period between the early and main
crops occurred simultaneously with a sudden drop
in temperature, extending the period over which
these poorer quality fruit were harvested. This
period would coincide with the period from Janu-
ary 24th to February 11th shown in Figure 1.

Optimum In-row Distance for
Eggplant Production
Bielinski M. Santos, Horticulturist

Native to India, this solanaceous crop
is in the same family as tomato and pepper.
Many eggplant types abound with different
shapes, sizes and colors. However, the
preferred types are purple with either round or
elongated fruits for consumption by both
conventional and ethnic markets.
Eggplant is one of the handful of crops
intercropped with strawberries. Although the
exact eggplant planted area in West Central
Florida is unknown, it is estimated over 200
acres of the crop are established beginning in
late January of each year before the end of the
strawberry season. Other production areas are
located in Southwest and South Florida,
where eggplant is transplanted as a "stand
alone" crop in single or double rows per bed
and 1,500 and 2,000 acres of eggplant are
grown in the state.
When intercropped, eggplant
transplants at the four-true-leaf stage (between
6 and 10 inches) are placed in single rows
between double rows of strawberries.
Growers used various in-row distances to
transplant eggplant, ranging between 12 and
36 inches, whereas the current IFAS-
University of Florida recommendation is
between 18 and 40 inches. Narrowing of this
wide range would provide growers with more
accurate information for eggplant production.
Thus, research was conducted to determine
appropriate in-row distances for eggplant.
These studies used 'Classic' eggplant,
which were transplanted at 1, 1.5, 2, 2.5, 3,
and 3.5 ft (between 12 and 42 inches) on
polyethylene-mulched beds at the Gulf Coast
Research and Education Center, IFAS,
University of Florida. Plant height was
measured at 6 weeks after transplanting
(WAT) and fruits were harvested 5 times
beginning at 8 WAT. Marginal return rates
(MRR) were calculated to determine which


practice had the highest economic returns.
Increasing in-row distances steadily
decreased plant height. However, fruit number
and weight remained unchanged between 1 and
2.5 ft (12 and 30 inches) between plants,
dropping sharply afterwards (see figure). Fruit
number and weight decreased 47 and 45%,
respectively, when distances changed from 2 to
3.5 ft between plants. The economic analysis
suggested that a distance of 2 ft had 8%
highest net profits than 2.5 ft. These results
indicated that there is no relationship between
plant height and yields, and growers could
establish this crop between 1 and 2.5 ft, but the
most appropriate spacing to maximize
economic returns seems to be 2 ft between
plants.

Flumioxazin (Chateau Herbicide)
Labeled for Strawberry Row Middles
William Stall, Professor, Horticultural Sciences

Chateau Herbicide WDG (Valent) has
received a supplemental label for use in
strawberry row middles. Chateau may be
applied at 3 oz per acre with a shielded or
hooded sprayer for the pre-emergence control
of a large number of broadleaf weeds.
Apply prior to weed emergence. Do not
apply after fruit set. Do not allow spray or
spray drift to come in contact with the foliage.



American Black Nightshade
Interference in Watermelon
William Stall, Professor, Horticultural Sciences

American black nightshade is a
problematic weed in watermelon production,
especially in south Florida. When watermelon
production follows tomato or pepper, the 3
major weeds are nutsedge, nightshade, and
pigweeds (Amaranths). In 1997, Terry et al.
found that 6 smooth amaranth (pigweed) per
meter, competing season-long in watermelon,
reduced yield 100%. Buker et al. (2003) found
that 2 yellow nutsedge plants per square meter
reduced watermelon yield 10% while 25
plants/m 2 reduced yield 50%. Until this past
year, there was no herbicide to control
nightshade in watermelon beds other than
methyl bromide.
Celeste Gilbert, a graduate student, has
completed a 2-year study, at two locations
looking at the competition of American black
nightshade in watermelon. Nightshade was
planted in watermelons at 2, 4, 6, and 8 plants/
m2 Reduction in yield was calculated against
a nightshade-free check. She ran two
experiments, one with open culture (non-
mulched) produced melons, and another with
watermelons grown on polyethylene mulch.
In both years, watermelon grown on


mulch had higher yields than those grown on
open culture. Yields were also greater for
melons grown in 2006 than 2005. 2005 was a
cooler, wetter year and watermelons did not
produce as well.
Percent yield loss of watermelon at 2
nightshade/m2 was 100% in 2005 on non-
mulched produced watermelons. In 2006, the
yield loss was 68% at 2 nightshade/m2 and up
to 93% at 8 nightshade/m2 competing with the
watermelon.
When watermelon was produced on
mulch, the yield loss in 2005 was 80 to 98%
at 2 to 8 nightshade/m2 and in 2006 the yield
loss was 54 to 88% at 2 to 8 nightshade/m2.
The bottom line is that watermelon is
a poor competitor with weeds. In these studies
as with the others, the number of melons
produced followed the same trend as the
yield. The size and quality of the melons were
not affected by the weed competition. Weeds
seem to impact fruit set more than fruit
quality.
Sinbar now (2006) has received
labeling for use in watermelon. Sinbar does
control both nightshade and amaranth. If
nightshade is a problem in the fields to be
planted to watermelon, it would be advisable
to consider its use.

Consumer Services (FDACS) registered the
fungicide cyazofamid (Ranman) for control
of diseases on cucurbits, potato and tomato.

As bacterocides on tomato and pepper. The
EPA registration number for the Omnilytics
product (AgriPhage) is 67986-1. (Federal
Reigster, 12/28/05).
On January 12, the FDACS
conditionally registered the insecticide
flonicamid for use on pome and stone fruit,
potato, cucurbit/fruiting/leafy vegetables
(Beleaf), and cotton (Carbine). The EPA
registration number for the ISK Biosciences
Crop. Product is 71512-9. This is a
cyanomethany triluroromethyl nicotinamide
insecticide with a different mode of action than
other products. It is effective against aphids,
thrips, leafhoppers, plant bugs, and other
sucking pests. It provides rapid anti-feeding
behavior and is non-toxic to beneficial insects.
(FDACS PREC Agenda 2/2/06).

Other Actions
In a new and historically interesting
move, the EPA has classified the soon-to-be
registered soil fumigant iodomet as "Not likely
to be carcinogenic to humans at doses that do
not alter rat thyroid hormone homeostasis."
There is compelling evidence indicating that
iodomethane induces thyroid follicular cell
tumors through an antithyroidal mode of action
(MOA). Although the fumigant has been
shown to be mutagenic in vitro, the weight of
evidence supports the antithyroidal MOA, as
evidence by the observation that only male
rodents exhibit increases in thyroid tumors, a
common response for this MOA. In addition,
the increases in cell growth (hyperplasia)
progressing to follicular cell tumors were only
seen in the presence of thyroid/pituitary
hormone changes, thus exhibiting a pattern of
both dose and temporal concordance. Do to
this classification, and the fact that the material
is quickly degraded or metabolized into non-
toxic degradates, the EPA has granted an
exemption from the requirement of a tolerance
for iodomethane when applied as a pre-plant
fumigant for pepper, strawberry, and tomato.

Pesticide Potpourri
Odors from foods ranging from garlic and onions to
ginger and strawberries may be nutritional signals that
the human nose has learned to recognize. Researchers
Stephen A. Goff and Harry J. Klee reported in Science
that, "Studies of flavor preferences and aversions suggest
that flavor perception may be linked to the nutritional or
health value" of foods. Flavor is complex and uniquely
challenging to plant breeders, they note, and as a result
has not been a high priority. The story explains that
Klee and Goff analyzed two types of tomato, the wild
cerasiforme and the commercially grown Flora-Duke.
Except for one chemical that also affects color, the
sugars, organic acids and volatile compounds associated
with tomato flavor were reduced in the commercial
product. For example, one of the volatile compounds
associated with the "tomato" or "grassy" flavor is called
cis-3-hexenal, which is also an indicator of fatty acids
that are essential to the human diet. They found that the
wild tomato contained more than three times the amount
of that chemical than the cultivated version. Two other
contributors to tomato flavor, 2- and 3-methylbutanal,
are indicators of the presence of essential amino acids
and are also three times more common in the wild
tomato. In addition to tomatoes, those chemicals are
also important constituents of the flavors of apple,
strawberry, bread, cheese, wine and beer. Goff and Klee
also noted that the scent compounds produced in many
spices are associated with health properties. (AP,
2/9/06).

Pesticide Labeling Issues and Food
Safety- Phyllis Gilreath, Manatee Co. Extension
A situation came up recently where a tomato
grower underwent a third party audit and he was
questioned and threatened with crop rejection because he
did not have the correct label. In this case, it happened
to be Monitor. The primary Monitor label does not have
tomatoes on the label! The label which does include
Monitor for tomatoes is a Section 24C label which is
issued as a supplemental label based on a special local
needs registration. You MUST have this supplemental
label in your possession to be legal! This may also be
pertinent for other materials. Make sure your pesticide
distributor provides you with any supplemental labeling
that you will need. Sometimes if you buy jugs that come
in a carton, look in the bottom of the carton before you
discard it. The supplemental label may be there. In
today's world of extreme scrutiny, especially in food
safety issues, you can't overlook anything. This is one
requirement that is not hard to meet. Growers make
sure you ask for supplemental labeling. Suppliers -
make sure you give your customers supplemental
labeling when required.

Highlights on Diagnostics and Late
Season Disease Control
Natalia Peres and Jim Mertely

This season has been a good one for
crown rot diseases. In November, December
and January, our Diagnostic Lab received 21
samples with Colletotrichum crown rot,
caused by C. gloeosporioides, 22 samples
with Phytophthora crown rot, caused by P.
cactorum, and 4 samples with charcoal rot,
caused by Macrophominaphaseolina. All of
these diseases are favored by warm tempera-
tures and prolonged periods of wetness, con-
ditions that often occur shortly after trans-
planting, but that have been unusually ex-
tended this season. These diseases are diffi-
cult to distinguish based on symptoms alone.
It is necessary to make isolations from in-
fected plants for identify the pathogen. Once
the pathogen is identified, specific recommen-
dations for its control can be made. The warm
weather during December-January was very
favorable to diseases and, in addition to crown
rots, samples have been diagnosed with fruit
rots caused by Botrytis cinerea or Colleto-
trichum acutatum, powdery mildew, leaf
scorch, southern blight, cyclamen mites, and
sting nematodes.
With the recent hard freezes in Cali-
fornia, the spring market looks very favorable
for Florida strawberry growers. Therefore, it
may pay to take measures now which will
prolong the strawberry plant health into
March. Although some plants may be looking
ragged due to previous damage by powdery
mildew or angular leaf spot, take heart. Plants
with some leaf damage caused by these dis-
eases can still produce a good crop. Fruit rot
pathogens are the greater threat this time of
the season. These include Botrytis cinerea
which causes Botrytis fruit rot, Colleto-
trichum acutatum (causes anthracnose fruit
rot), and Rhizopus /Mucor spp. (the cause of
leak disease). All three pathogens are favored
by rainy, wet weather for spore production,
spore dispersal, and infection. However, they


are also strongly influenced by temperature.
The optimum temperature for Botrytis is 62 -
770 F, while temperatures from 75 850 F are
more favorable for anthracnose and leak dis-
ease. This explains why Botrytis fruit rot
typically causes losses in February, while an-
thracnose and leak disease are more serious in
March.
Thankfully, very little anthracnose
fruit rot has been observed up to now. How-
ever, if the season continues into March, in-
oculum levels will build up and, chances for
an epidemic of anthracnose fruit rot will in-
crease. If symptoms are already present in the
field, care should be taken to remove infected
fruit from the canopy and from the field if
possible. Applications of the protectant fungi-
cide captain should continue on a regular ba-
sis. Tank-mixing captain with a strobiluran
fungicide (Abound or Cabrio) or Switch may
helpful. These measures are especially rec-
ommended if susceptible varieties (Camarosa,
Camino Real, and Treasure) are being grown,
and may also be necessary to protect
'Strawberry Festival', which is moderately
susceptible. If no symptoms are present in the
field, applying captain or thiram alone is a vi-
able low-cost alternative which should be
coupled with a strong scouting program. An-
thracnose fruit rot is a particularly dangerous
disease, since epidemics develop rapidly, and
are difficult to control even with our best fun-
gicides once underway.
Little information is available con-
cerning leak disease. If some of your fruit
seem to melt on the vine and splatter when
tossed into the alleys, fungi such as Rhizopus
or Mucor are the likely culprits. These fungi
are primarily wound pathogens, so any meas-
ures which reduce fruit injury or insect dam-
age should help. Timely harvesting is essen-
tial since ripe fruit are particularly susceptible
and also increase fruit fly numbers, which
spread the disease. Captan and Thiram may
suppress these fungi somewhat, but no fungi-
cides specifically labeled for the control of
leak disease.
