2005 Bird Damage Survey

The last page of the
newsletter is a survey about the bird
damage this year in the strawberry
fields. It is very important that
everyone complete the survey and
return it to me. To effectively
combat this problem in the future, the
industry needs to be able to show
government officials the economic
impact this is having on individual
growers and the industry as a whole.
A large number of completed surveys
also shows that this is an industry-
wide problem and not just the
problem of a few growers.
If you have a crop other
than strawberries, and robins or other
birds such as cedar waxwings have
caused damage please fill out the
survey and tell me what crop is being
affected and the type of bird. This
information helps provide a case for
all farmers to be able to protect their
crop.




Botrytis Blossom Blight
on Southern Highbush
Blueberry
Alicia Whidden

This article is based on a paper by
Dr. Philip Harmon which is available
at EDIS http://edis.ifas.ufl.edu/
PP119.
Botrytis is an important
disease of many fruits and
vegetables. It is caused by the


fungus, Botrytis cinerea, which
usually causes infection through
wounds or by living on dying plant
tissue. In strawberries and
blueberries it can cause infection in
the flower when the petals do not
drop away after the flower has been
pollinated. Frost or freeze damage
can cause wounds on tender growth
or delay petal drop and this gives the
fungus an entry point to cause
infection. Since Botrytis can survive
very well as a saprophyte, meaning it
can live on dead tissue, spores of the
fungus can be present at bloom time
to infect flowers.

Long periods of high
relative humidity favor fruit

increase Botrytis blossom blight.

temperatures- from 32' to over 70.
When leaves are wet for more than
24 hours the chance ofbotrytis is
significantly increased. The rain we

and the first of March could cause increased Botrytis
Blossom blight in blueberries this year.
Botrytis blossom blight can infect one fruit in a
cluster and if conditions are right can produce enough
spores to infect other berries in the cluster making the
whole cluster of fruit unmarketable. Sometimes the
pathogen can lie dormant and after harvest while in
storage it can begin growing and cause postharvest rot.

Good and Bad Thrips in
Strawberries
S.I. Rondon and J.F. Price

Florida possesses two types of thrips that are
very important to successful strawberry production. One
is a good thrips and the other is a bad thrips. This article
discusses the two groups of thrips and makes comments
on their impact.

The Bad Thrips. Even though it can be a downer to
bring up the bad item first, management of this bad item
has a bigger impact on our strawberry production than
the good item, so the bad shall be first.
Frankliniella bispinosa (Morgan), the flower
thrips (Fig. 1), is the principal thrips of concern to
strawberry producers in Florida. It is a small, very
slender insect, less than 1/16 inch long or about the size
of the most recent splinter tweezered from your finger.
Usually we find flower thrips on Plant City area
strawberries when oaks and citrus begin to bloom in
February and March.
Thrips perform poorly at flying because their
fringed and feathery wings are better suited for carrying
(Continued on page 3)

them with wind currents. Adults are usually yellow but
can vary from light yellow to dark brown. Nymphs are
white or pale yellow (Fig. 2). Immature stages are
wingless but they can move very quickly around the
strawberry flower or small fruit.

Damage and Biology. Thrips injure the plant by
rasping and sucking the exuding sap of the strawberry
bud, flower and leaf tissues. Thrips feeding on
strawberry blossoms can cause the stigmas and anthers
to turn brown and wilt prematurely (Fig. 3). As fruits
develop, thrips feeding may cause a russeting of the fruit
around the cap, however, this injury is seldom
economic. Thrips also can scratch tissues around the
achenes of very small, developing fruit. That damage
later can look like the bronzing also caused by adverse
weather and other factors.
Thrips develop through several generations a
year in Florida. The egg to adult development period is
approximately 2 weeks at our warm late-winter
temperatures.

Monitoring. To avoid losses to thrips, growers should
start checking strawberry flowers for thrips when the
first flowers begin to open. These insects are small and
a 14X hand lens is helpful. To sample thrips, randomly
collect flower blossoms and strike flowers onto white
paper or "huff' air at your lips onto the flowers. Then
quickly look into the flower with the lens to see the
thrips running about.

Control. The insidious flower bug, Orius insidiosus
(Figs. 4 and 5), is an important naturally occurring
enemy of flower thrips and helps to keep thrips
populations in check. But when flowering is in progress
and thrips suddenly increase to about eight or more per
flower, it is time to consider an insecticide treatment.
Low impact insecticides such as Spintor can control
thrips and spare beneficial parasites and predators.

Good Thrips. The sixspotted thrips, Scolothrips
sexmaculatus (Pergande), is a predator. Its shape and

to the more common flower thrips and is usually tan,
yellow or light brown. Most thrips at rest hold their
wings extended straight down the top of their backs.
Patterns in wings of resting sixspotted thrips form three
pairs of dark spots along the distance of the wings,
making the insect's back appear as though it has six
spots (Fig. 6).
We regularly see sixspotted thrips at work in
Plant City area strawberries once spider mites appear.
Sixspotted thrips routinely are major agents in cleaning
up abandoned, spider mite-infested fields.

Biology. Sixspotted thrips eggs are laid in leaf tissue
where they hatch in about 1 week. This species hunts
for food, including small mites, their eggs, and small
insects on strawberry leaf surfaces. Thrips nymphs
(immatures) can eat about 100 spider mite eggs during








Berry/Vegetable Times


their development and an additional 60 spider mite eggs
every day of their approximately month-long adult life.
Broad spectrum insecticides such as Lannate kill these
beneficial and limit their usefulness to growers.
The management of the two groups of thrips is
very important to successful strawberry growing.
Weekly scouting with a 14X hand lens and informed
choices of insecticides can help strawberry growers limit
losses from the bad thrips and maximize benefits form
the good thrips.


Strawberry Latent Ringspot Virus
Found in North America
David Elstein

Strawberry latent ringspot virus, a problem for
the past 30 to 40 years in Europe, has just been
discovered in North America by Agricultural Research
Service (ARS) scientists and cooperators. Scientists
with ARS, Oregon State University, and Elmhirst
Diagnostics and Research of British Columbia found the
virus on 17 percent of the California strawberry samples
and on four percent of British Columbia strawberries.
The virus was also found in a variegated mint. The
virus, which can dramatically decrease yields, is spread
by nematodes, so the scientists were surprised to find the
virus in California strawberries, as most are planted in
pre-fumigated soil.
Plant pathologist Robert R. Martin of the ARS
Horticultural Crops Research Unit in Corvallis, Ore., is
leading the agency's efforts in studying and preventing
the virus. The group discovered the virus by doing a
broad-spectrum test to look for viruses that may be
involved in strawberry decline and variegation of mint.
They compared nucleic acid and protein sequences of
the virus from strawberry and mint to those in databases.
The scientists believe that the virus has been in this
country for many years on an ornamental mint sold
throughout the United States--popular because of its
bright-yellow color--without anyone noticing. It turns
out that the color partially comes from the ringspot
virus.
Many of the chemicals that have been used to
control this and other viruses transmitted by nematodes
are being pulled from the market because of
environmental concerns. Martin and ARS colleague
Jack Pinkerton are studying alternative ways to control
nematode-transmitted viruses, such as rotating a crop
that is not a host for the virus so that the nematodes lose
the virus and are no longer able to transmit it.
While the virus has only been found on mint and
strawberries in the United States, it can infect many
broadleaf crops.

UF Expected to
Release New
Strawberry
Cultivar this Spring
Craig Chandler

The release of FL 97-39,
tentatively named 'Winter Dawn', is expected by the
University of Florida this spring. During the second half
of February, this selection surged past other cultivars in
total yield. The few growers trialing 'Winter Dawn' this
season have been very pleased with its performance. It
isn't going to be competitive with 'Festival', in terms of
overall fruit quality, when berries are plentiful, but it can
help growers increase their early season output. My
recommendation is for growers to plant not more than 5
to 10% of their acreage in 'Winter Dawn' and to stop
harvesting it by the end of February -- before we have
much hot weather. This acreage can then be devoted to
a double crop. Taking acreage out of production at the
end of February will lower the amount of fruit on the
market in March, which will hopefully help to extend
the season.
'Winter Dawn' fruit are firmer and more
resistant to abrasion than the fruit of 'Sweet Charlie',
but they are not as firm as the fruit of 'Festival'. Also,
this fruit is not as resistant to rain damage as the fruit of
'Festival'. On the positive side, 'Winter Dawn' is
moderately resistant to Botrytis and anthracnose fruit
rot. The recommended planting period for 'Winter
Dawn' in west central Florida is September 25th to
October 10th.

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

Strawberry diseases have been at very low
levels this season. Amazingly, only one strawberry
sample was received during the whole month of
February at our Diagnostic Clinic. This sample had an
abiotic problem, and wasn't even diseased. The dry
weather from mid-January to February 24 may explain
this low disease pressure.
Nearly two inches of rain fell from February 25
to 27, and with the weather remaining relatively cool,
conditions have been ideal for the development of
Botrytis fruit rot. Fields that were flowering during this
period should have been protected by applications of
fungicides with good activity a'ainist 1r, Ii cinerea,
such as Pristine, Elevate, Switch, or Scala. In our
experiments, Botrytis is controlled more effectively by
early applications during peak bloom than by late
applications during the main harvest period. Because
Botrytis fruit rot is suppressed by hot weather, special
applications ofBotryticides are usually not needed after
February. However, if the disease has caused losses in
February, and the weather remains mild, alternating
applications of a Botryticide and a protectant fungicide
captainn or thiram) should be continued.
Very little anthracnose fruit rot, caused by the
fungus Colletotrichum acutatum, has been observed this
season. At this late date, it is unlikely that an epidemic
will occur since the season is near the end and there is
not enough time for the inoculum to build up. However,
if symptoms are present, applications of a protectant
fungicide such as captain, alone or tank mixed with
Abound, Cabrio, or Switch should protect the crop until
the end of the season.



Site Made Available for
Strawberry Museum
and Hall of Fame

On Tuesday, February 2,
2005 the Hillsborough Board of
County Commissioners voted
unanimously to transfer property to
The Florida Strawberry Research and Education
Foundation (FSREF) for the development of a Florida
Strawberry Museum and Hall of Fame. The 21-acre
parcel currently houses the Gulf Coast Research and
Education Center at Dover. The University of Florida
faculty at the Dover Center will be transferred to the
newly constructed Gulf Coast Research Center in Balm.


Ribbon cutting for the Balm facility is slated for April 1,
2005 (no fooling). The strawberry community has long
sought a means to display the unique archives of the
century old Florida strawberry industry. The vacating of
the Dover facility, itself rich in strawberry history, made
the location for the Florida Strawberry Hall of Fame and
Museum a natural. This is but the first step toward
making the Florida Strawberry Hall of Fame and
Museum a reality. FSREF is looking for artifacts and
development resources within the community. If you
have an interest in being a part of this endeavor, please
contact the Florida Strawberry Growers Association at
813-752-6822.
The Florida Strawberry Growers Association
and the Florida Strawberry Research and Education
Foundation are non-profit organizations that serve the
Florida strawberry industry as partners in research,
promotion and member/community service.



Can't Live with 'em, Can't
(Shouldn't) Shoot 'em.
John R. Duval

This has been a terrible season for avian pests.
Robins arrived early and have severely worn out their
welcome. The best we can hope for is warm weather to
our north so that the little ,#"o$^A&#! will move on.
Damage to the crop being grown at the GCREC-Dover
has been monitored in our cultural management trials.
During the first two weeks of the scourge, active efforts
to deter the birds were performed. However, after
February 10th minimal effort went in to scaring off the
birds. The chart below shows how the damage has
progressed in our field. Damage peaked on January 31st
and again on Valentine's day then progressively
decreased as birds have moved north (or have gotten
full). The area of our field where this data was collected
is near a heavy traffic area which probably lessened
damage to those experimental plots. However, in more
remote sections of our field, entire experiments were
devastated.
Besides examining damage at our own field,
we scouted four commercial fields. For each 10 acre
block, data was collected from forty plants in a single
row. Samples were taken between 100 and 500 feet of
the tree line from a section that had not been harvested
for at least 1 day. This was repeated 2-3 times across
the fields. Robin control measures at these farms
consisted of minimal efforts (reflective tape in field) to
heavy use of shotgun shells and fireworks to scare the
birds. We found an overall damage at 8.4%, with a
range of 3.3% to 11.8%. What was surprising was that
similar levels of control measures had very different

results. In addition, minimal efforts produced similar
results to those obtained by farms using the heavy
artillery. Damage seemed to be most heavy on farms
that were situated in areas with the greatest acreage of
berries, and where farms were more isolated, there was
less damage.
This data, possibly combined with economic
analysis, is a documented basis to request research funds
and permits in the future for the control of robins.

Do you have an idea for a value-added
agricultural product and need funding to get the project
off the ground? The Hillsborough County Cooperative
Extension Service, Hillsborough County Agriculture
Industry Development Program, and the USDA are
teaming up to provide a workshop on the USDA Value
Added Producer Grant Program. For the past few years,
the USDA has been awarding grants to farmers,
cooperatives, producer groups, or producer-based
business ventures for business planning activities, such
as conducting a market analysis or developing a
marketing plan, to establish a value-added marketing
opportunity for an agricultural product, acquire capital
to establish or improve a value-added agricultural
enterprise, and capital for farm-based renewable energy.
The maximum award per grant has been $500,000 and
matching funds are required.
This workshop will help participants learn
more about value-added agriculture, opportunities that
may exist locally, and how to apply for the USDA
Value-Added Producer Grant. Some of the topics will
include: a description of value-added agriculture,
potential value-added strategies, and resources to assist
value-added agriculture projects. This workshop is free
but seating is limited. Please register by calling Traci

Asian Soybean Rust and Its Effect
on Central Florida
Alicia Whidden

On March 1 it was announced that Asian
Soybean Rust (ASR) was found near Dade City in
Pasco County on kudzu. Even though we do not grow
soybeans, ASR is still of great concern for us. This is
the southern most finding of the disease and there are
now 18 counties with confirmed rust. The problem for
us in central Florida is that beans and peas are also hosts
of ASR and we do grow those. Also we have several
thousand acres of Iron Clay peas as a cover crop during
the summer. On March 3 the first ever forecast of the
potential of epidemic spread of this disease was made
due to the Dade City find and the weather patterns. The
North American Plant Disease Forecast Center issued a
moderate threat outlook with a strongly moderate risk
for susceptible plants in central and northern Florida
except the panhandle.
Asian Soybean Rust is caused by Phakopsora
pachyrhizi. It was first detected in 1902 in Japan and
since then it has slowly moved around the world. It
went from Asia to Africa and then to South America
where it has been an important disease in soybeans in
Brazil. It has been a disease of major concern to watch
for in the US and last November it was found in
Louisiana and within a few weeks it was found in 9
southern states. It is believed that Hurricane Ivan
brought the disease to the US. Besides soybeans it has
been found on over 90 other bean species and we have
many of those in the state.
ASR can be difficult to identify in the early
stages since it can look like other foliar diseases.
Usually lesions are seen on the lower part of the plant
canopy. At first the leaves will have a yellow mottled
appearance but as the disease progresses the leaves turn
yellow then brown or red pustules will appear usually on
the bottom of the leaf. There will not be a yellow halo
around the lesion like with bacterial diseases. The
lesions can be on any above ground part but are usually

I









Berry/Vegetable Times


seen on the leaves first when scouting. The only way to
be sure it is ASR is to do a molecular test called PCR
which is done at a state testing lab. Since we have about
850 acres of peas and beans as well as all the acres of
cover crop peas, it is important if you see any leaf
problems to call me so a sample can be collected and
testing done to correctly identify the problem. The only
control measure in soybeans at this time is fungicides
labeled for ASR.

Pesticide Registrations and Actions
* Three label revisions have been made on the
Telone products which currently have 24(c)
registrations in the state of Florida (FL-990003, FL-
990004, and FL-990005). In addition to the
removal of the statement concerning no treatment
within 100 feet of drinking wells (because this
statement is already on the national label), the SLN
labels now reflects that chisel injection is not the
only means of application. Additionally, the
statement regarding training has been modified to
state that the material is available only to people
who have a restricted use pesticide license.
(FDACS letter of 12/22/04).
* The methyl bromide CEUs were signed in the final
moments of 2004. In Florida for 2005, the fumigant
may be used by growers of tomato, pepper (all
varieties), strawberry, and eggplant, specified
growers of flowers, trees, and turfgrass, as well as
some golf courses. If you need methyl bromide, be
prepared to deal with documentation and keep good
records, as the penalties for misuse can be
financially crippling. (FFVA Bulletin #68,
12/22/04).
* A recent Plant Health Progress bulletin reported
widespread occurrence of strobilurin-resistant
gummy stem blight in Georgia watermelon fields.
Fields and transplant house were sampled in 2001
and 2002. Of the 272 isolates collected in 2001,
247 (91 percent) were resistant to azoxystrobin. In
2002, 82 percent of the isolates were resistant to
azoxystrobin. Of the 40 isolates from watermelon
transplants, 39 were positive for resistance. These
results lead Georgia researchers to believe that
resistant isolates in the field may have originated
from seed or transplants and they are now advising
their growers to avoid this class of fungicide (as
well as strobilurins mixed with boscalid). (Plant
Health Progress, 12/7/04).
* On January 6, the Florida Department of
Agriculture and Consumer Services (FDACS)
issued the Special Local Needs registration SLN
FL-040011 to Bayer CropScience for a reduced
plant back restriction (from four months to 30 days)
with the use of Scala (pyrimethanil) fungicide on
"other crops" (crops not on the label). (FDACS
PREC Agenda, 2/3/05).
* On January 6, the FDACS issued the Special Local
Needs registration SLN FL-040012 to Nichino
America, Inc., for use of Courier (buprofezin)
insecticide on field tomato to control whitefly
nymphs. (FDACS PREC Agenda, 2/3/05).
* On January 6, the FDACS registered the fungicide
Reason (fenamidone) for use on potato, tomato,
cucurbits, lettuce, and other crops to control


diseases. Fenamidone is a respiratory inhibitor that
has foliar protectant and curative activity against
oomycete (downy mildew) and some ascomycete
fungi, as well as Alternaria. The EPA registration
number for the Bayer CropScience product is 264-
695. (FDACS PREC Agenda, 2/3/05).
* On January 6, the FDACS registered the
biofungicide Sonata (Bacillus pumilus strain QSY
2808) for use on potato, tomato, strawberry,
cucurbits, and many other crops to control diseases.
The EPA registration number for the AgraQuest,
Inc. product is 69592-13. (FDACS PREC Agenda,
2/3/05).
* Effective January 7, a quarantine exemption has
been issued for the use of Stratego (trifloxystrobin
and propiconazole) on soybean to control soybean
rust. The EPA registration number for the Bayer
CropScience product is 264-779 and the expiration
date is 12/1/2007. (FDACS letter of 1/19/05).
* Based on a request by Syngenta and IR-4,
tolerances are approved for the insecticide
thiamethoxam (PmImnumi i L Acl .)). Tolerances of
importance to Florida include blueberry, potato,
strawberry, legume vegetable (group 6), and root
vegetable (group 1B). (Federal Register, 1/5/05).
* In at least a temporary diversification away from
genetically modified crops, Monsanto has agreed to
pay about $1 billion to acquire Seminis, the world's
largest producer of fruit and vegetable seeds.
Executives were cited as saying that Monsanto
would develop new vegetable varieties using
conventional breeding, and that the fruit and
vegetable seed business could grow without
biotechnology, based on a consumer movement
toward healthier diets. The new acquisition not
only makes Monsanto the largest supplier of
vegetable seeds in the world, but also, according to
the company's calculations, the largest seed and
biotech company over all. It would surpass
DuPont, which owns the corn seed giant Pioneer
HiBred, in terms of revenues derived from seeds
and biotech traits. Seminis, based in Oxnard, CA,
had sales last year of $526 million, with its leading
products being tomato, cucumber, bean, and pepper
seeds. Its main brands are Seminis, Asgrow,
Petoseed and Royal Sluis and it sells mainly to
farmers, not gardeners. But, with partners, it has
recently started to develop some consumer items,
like the Bambino miniature watermelon and Lettuce
Jammers, lettuce in the shape of a taco shell. Its
main rivals in fruit and vegetable seeds are
Syngenta of Switzerland and Limagrain of France.
Less than one percent of Seminis's sales come from
genetically modified seeds. (New York Times,
1/25/05).
