II. PESTICIDE UPDATE

A. Crisis Exemption for the Use of Trigard on Tomatoes

Doyle Conner, Commissioner, Florida Department of Agricul-
ture and Consumer Services, utilizing the crises provisions of
Section 18 of the Federal Insecticide, Fungicide and Rodenticide
Act as amended, declared a crises exemption for the use of
Trigard 75WP for the control of the tomato leafminer in Florida
on March 16, 1983. A petition for a specific exemption is being
prepared.

(Stall)

III. COMMERCIAL VEGETABLE PRODUCTION

A. Section 18, Specific Exemption Labels: Caution Statement.

On December 3, 1973, there was published in the Federal Re-
gister (FR Vol. 38, No. 231) regulations governing the exemption
of Federal and State Agencies for the use of pesticides under the
emergency provisions of Section 18, of the FIFRA, as amended by
the FEPCA of 1972. Under the provision of the law the Adminis-
trator may exempt a Federal or State Agency from the requirements
of the Act if he determines that conditions exist which may re-
quire such an exemption.

These regulations provide for three (3) types of exemptions,
Crisis, Quarantine Public Health and Specific Exemptions.

The specific exemption is extremely important in vegetable
production due to the lack of Federally registered pesticides and
the abundance of difficult to control pests in the state.

Each specific exemption must be requested, in writing, by
the head of a Federal Agency or the Governor of the state in-
volved, or his official designee. In Florida, the official
designee is Doyle Conner, Commissioner, Florida Department of
Agriculture and Consumer Services (FDACS). Detailed information
must be submitted with the request. The information package is
completed and submitted to FDACS by a petition (individual or
group) with the support of the products) manufacturer. The com-
pany must be willing to distribute the product under the proposed

emergency label. If the specific exemption is granted the pro-
duct may be applied only for the pests indicated and only under
the restrictions on the exempted label.

The initial Section 18 labels granted in Florida have been
insecticides and fungicides. The control received under these
exemptions have been very good and the crop tolerances excellent.
Herbicides have also been granted specific exemptions under Sec-
tion 18, in Florida.

Growers should be extremely careful in the use of new herbi-
cides. Herbicides react quite differently in the many different
soil types and environmental conditions found in Florida. It is
a standard recommendation that a grower try a new herbicide on a
small trial basis to check efficacy and phytotoxicity before ap-
plication in a large production field. Because of the emergency
nature of Section 18 labels, this is not always carried out.

Application equipment should also be carefully calibrated.
There is a narrow range of rates for many herbicides that is both
effective and safe for the crop.

Herbicides that have Section 18 labels many times have not
been tried on all soil types in the state. What is known is that
the product is effective and safe at the rates indicated from
tests conducted at two or more locations within the state.
County Agents, consultants and farm service and supply represen-
tatives are obligated to advise the grower that the product is
labeled. It is also important that they caution the grower on
its use. Herbicides should not be recommended until they are
tried under local conditions.

The petitioner for the Section 18, specific exemption for
Dual on broccoli, cabbage and collards, after consultation with
Ciba-Geigy, has asked FDACS to request that the specific exemp-
tion be rescinded. This request was due to the occurrence of
phytotoxicity on one of the labeled crops and to cauliflower,
which is not labeled. This occurred in only one area of the
state.

When actions such as this must be taken, the vegetable in-
dustry as a whole in the state is affected.

An important point to remember is that the disregard of re-
strictions on the Section 18 label or simply not following all
restrictions, plus failing to use caution in the application of
the pesticide, may jeopardize the entire Section 18 program.
This is true for all types of pesticides, not just herbicides.
Applicators should keep in mind that:

1. A section 18, specific exemption is an emergency use
label only, not a federal label.

2. All restrictions on the exempted label must be followed.

3. Caution should and must be followed in the use of the
product.

Following the above practices will lead to an orderly pesti-
cide registration.

IV. HOME VEGETABLE GARDENING

A. Know Your Minor Vegetables Potherb Mustard

Potherb mustard (Brassica juncea var. japonica) is an orien-
tal cooking green also known as mizuna, kyona, Japanese greens,
and sometimes California peppergrass. It is widely grown in
Japan, but only occasionally in gardens in the U.S. and Florida.

In appearance, potherb mustard has about the same plant
height (12-18"), color (yellow-green), and texture (smooth and a
bit fuzzy) as curly mustard, but the leaf shape is quite differ-
ent. Leaves of potherb mustard are deeply-notched, feathery, and
quite attractive. They are clumped in a compact 12 inch diameter
bunch.

In the Florida garden grow potherb mustard at the same time
of the years as other cool season greens September through
March. It withstands frost and light freezes, but is not quick
to seed even in periods of warm weather which occur during the
winter months.

Start potherb mustard by sowing seeds directly in the gar-
den. Sow seeds 1/2 inch deep in rows spaced 12 to 18 inches
apart. Thin out the seedlings so that plants stand 6-12 inches
apart. Use the extra plants as they are thinned, or transplant
to other areas of the garden.

Prepare the garden soil much as you would for other vege-
tables. Apply about 2 pounds (1 quart) of 6-6-6 fertilizer per
100 sq ft at planting time, broadcast into the planting bed.
Then follow with a sidedressing of a similar fertilizer about 3
to 4 weeks after seeding. Be sure to water frequently.

In the garden at Gainesville, few if any pests bothered the
mustard in the fall and winter.

Harvest and Use -- The leaves are ready for use anytime
after about three weeks of growth. Break off as many leaves as
needed, but keep enough young foliage to continue regrowth. If
you prefer, harvest the entire plant, to make room for planting
some other kind of vegetable.

The leaves may be eaten raw, as in a salad, but the taste is
too mild to be enjoyed this way. The ornate leaves make the
salad more decorative, however.

As a potherb it is prepared in many ways as a steamed or
boiled well-seasoned green; stir-fried; in soups; or mixed with
other vegetables.

Like other mustard, potherb-mustard is rich in vitamins and
minerals.

B. Plant Sciences March Issue 4-H Digest

The March issue of the 4-H Digest is designed to help you
take advantage of the resources available through the National
4-H Council in the program area of Plant Sciences.

There are numerous activities listed to help your 4-H'ers
become more involved in areas such as entomology, commodity mar-
keting, agriculture, gardening and horticulture and plant and
soil sciences. The activities will undoubtedly develop leader-
ship skills in both youth and adults in plant sciences and will
open many doors for exploring career opportunities.

Also included in this issue are a listing of corporations
that will help you stimulate excellence in these programs by pro-
viding incentives and awards and other support at county, state
and national levels.

The last page of the Digest list many of the educational
aids member and leader manuals, slide sets and special publica-
tions that relate to these program areas.

A copy of the March issue of the 4-H Digest can be found in
the March 1983 National 4-H News Magazine or through Dr. Tom
Greenawalt, 4-H Department, 109 Rolfs Hall, University of
Florida, Gainesville, FL 32611, (904) 392-1744.

The program this year will emphasize vegetable crops and
touch on other areas such as ornamental horticulture and fruit
crops.

For more registration information call Dr. Tom Greenawalt,
4-H Department, University of Florida, (904) 392-1744.
