I. COMMERCIAL VEGETABLES

A. Transplant Growers Meet.

Prompted by the increasing threat
of Tomato Spotted Wilt Virus (TSWV)
movement within the state, vegetable
transplant growers convened in Immokalee
on January 8, 1991. Members of eight
prominent production houses met along
with representatives of Yoder Brothers,
Glades Crop Care, and IFAS to discuss the
TSWV problem with the vegetable
transplant industry.
A pivotal question was "Have any
Florida vegetable transplants been
diagnosed with TSWV or geminivirus?" A
report submitted to the group by Dr. Gary


Simone indicated that all (suspect)
transplant samples received at the FL
Extension Plant Disease Clinic, thus far
have tested negative for the presence of
either virus. Delineating the advance of
TSWV within the state, IFAS researchers
indicated that it had not progressed
further south than Levy and Marion
counties in great quantity, but has been
devastating in the panhandle and northern
Florida.
Dr. Charles Mellinger, Glades Crop
Care, said his organization has carried out
surveys over the past several years on
thrips populations from Quincy to
Homestead. His data indicates that, while
known vectors are rare but increasing in
South Florida, the incidence of TSWV is
still low especially in the SW production
area. As the development of new virus
diseases generally follow exponential
patterns, Mellinger stressed that
sanitation, ie. exclusion of infected material
from an area, is of the utmost importance
in slowing the progression of the disease.
That is, the longer we can keep TSWV
above the present dividing line, the longer
we will be virus free.
Much discussion about other state's
stringent certification requirements for
importation of Florida transplants left
growers shocked to learn that under
tomato transplant regulations issued by
DPI "Tomato plants and other vegetables
do not require inspection or certification
for movement INTO or within the state,
when they are apparently free from
injurious insects and diseases." DPI could
invoke Rule 5B-2.011 should they believe a
problem may be apparent, but this is
certainly more lenient than most states
where Department of Agriculture
personnel meet EVERY shipment of
Florida transplants being off-loaded!
DPI's position is that transplant
importation from other states is
"inconsequential" and does not justify
specific regulation because the virus and
vector are already present in Florida.
TSWV may be present in FL, but not south









of the dividing line! The group decided to
state their concerns to DPI in a position
paper of their own requesting more
inspection of incoming material (especially
from areas known to be hotbeds of TSWV)
to reduce the southerly spread of the
disease. This seems prudent as all the
major transplant producing houses fall
below this dividing line.
IFAS researchers suggested a TSWV
county agent survey to add to existing
information on the demographics of TSWV.
It is important to allay public fear (both
within the state and nationally) that our
transplants may contain virus, and this can
best be done by creation of a TSWV-free
zone and keeping it that way.

B. Chinese Cabbage for Central
Florida.

Commercial production of Chinese
cabbage in central Florida is usually limited
to a few acres on muck soil, but during
1989-90 over 200 acres were planted on
sand. Production and yields were
outstanding, but marketing was a failure.
Seedbeds were sown on January 22,
1990, to evaluate 26 varieties of Chinese
cabbage to be grown on a flatwoods soil
(Myakka fine sand). Seedlings were
transplanted and a duplicate trial was
direct-seeded on February 28. A
randomized block design with a single-row
plot 25 ft long by 2.5 ft wide with an in-row
spacing of 11 inches was used. Harvesting
began on April 27 and ended May 7. Each
entry was harvested when it was judged to
be mature. Plots were harvested only
once. Of the highest-yielding entries,
Harbin, Spectrum, China Flash, Blues,
China Express, and Hopkin finished in the
top 10 (by total weight) in both the
transplanted and direct-seeded trials.
Yields were comparable in the
transplanted and direct-seeded trials,
however, the transplanted trial was ready


for harvest an average of two days earlier.
The warm spring did not give the
transplants as much of an advantage as
expected.
The average head weight for the top
yielding entries ranged from 3.46 to 4.49
lb. There was no differences found in
average head weight between the
transplanted and direct-seeded trials.
Three entries had spines or were prickly to
the touch when harvesting. Removing the
outside leaves reduced the spines and they
were not considered a major problem. Tip
burn, which was accentuated by warm, dry
weather, was found in China Flash,
Spectrum, and Blues. There did not seem
to be a relationship between transplanted
or direct-seeded and tip burn.
A more complete report may be
obtained by requesting Research Report
SAN 91-02, Chinese Cabbage Cultivar
Trial.

C. Status of Greenhouse
Vegetable Industry in Florida.

The greenhouse vegetable industry
in Florida has increased over the last few
years. In discussions with greenhouse
researchers and industry personnel from
other states, it appears that Florida is now
the top greenhouse state in the country.
Information on the size and characteristics
of our greenhouse vegetable industry are
presented in the following summary which
was completed in January, 1991.

III. PESTICIDE UPDATE

A. Lorox DF Labelled for Use
on Parsley.

Lorox DF has obtained a label for
use for control of certain weeds in parsley
only in states east of the Mississippi river.
In mineral and muck soils, make a
single broadcast application to the soil
surface at the rate of 0.75 to 1.5 lb ai after
planting but before plant emergence. Use
the lower rate on sands and the higher rate
on muck soils.
Muck soils only ... one additional
application may be made to parsley grown
on muck soils to control emerged weeds.
Make application after parsley emergence
when weeds are in 1 to 3 leaf stage. Use a
maximum rate of 0.5 lb ai per acre. Do not
make application within 30 days before
harvest.
A maximum rate of 1.5 lb ai may be
applied per acre per year. The supple-
mental label must be in the possession of
the user at the time of application.

IV. VEGETABLE GARDENING


A.
Received.


4H/SSU ELM Proposals


administered by our 4-H Advisory
Committee for Horticultural Programs
(which I chair at the moment).
The SSU grant provides for an
allocation of $725 to each of six county
projects selected. The granting period is
for 5 months duration beginning March 1,
1991 and ending with reports of
accomplishment due August 1, 1991. All
4H and horticulture agents should have
received a complete set of forms and
regulations back in December.
The initial response to this program
has been gratifying. At the passing of the
deadline (Feb. 1) we have received 19
applications for the ELM grants. All of
these proposals appear highly meritorious
at quick glance. Obviously the job ahead is
to review the proposals and select those
few (about six) that can be funded. That
difficult task will be attempted by a
committee of four, including a
representative from each of these
interested parties: county faculty, state 4H
faculty, state horticulture faculty, and the
SSU sponsor.
The following is an alphabetical
listing of the proposals submitted. From
these we shall select those to be awarded a
grant, and will notify all applicants of the
outcome just as soon as the selection
process is completed.


In December 1990 I introduced
Extension agents to a new water quality
and conservation project that 4-H members
can conduct. The project would provide
agents a way to participate effectively in
the USDA's National Water Quality
Initiative and contribute toward one of
Florida's most critical needs better quality
water conservation.
The name of the project is "Florida
4-H/Southern States Utilities -
Environmental Landscape Management (4-
H/SSU-ELM). It is based on a grant to the
Florida Cooperative Extension Service from
Southern States Utilities (SSU), and

We appreciate the efforts of all agents who

We wish all of these projects could be
funded. In the next issue of the
Vegetarian we will post a list of the
proposals that will receive funding. Of
course, we are grateful to Southern States
Utilities (SSU) for this project, and look
forward to some outstanding
accomplishments to report as a result of
their commitment to this worthy cause.
