1. New Seed Potato Regulation

The following has been recommended and will probably be in
effect for seed potatoes shipped into Florida beginning In the
fall of 1969. This has become necessary because of low quality
seed being sold in Florida for many years. This regulation will
be administered by the florida State Department of Agriculture.

Chapter 7B-33


78-33.01 Purpose.--This regulation is deemed necessary in order
to prevent the introduction and spread of destructive pests of
seed potatoes, to insure potato growers of a source of high qual-
ity planting stock, and to promote the general welfare of the

7B-33.02 Sale of seed potatoes restricted.--It shall be unlawful
for any person, firm, association or corporation to offer or
expose for sale, or ship into this state, any potatoes or parts
thereof Intended for propagation, except as prescribed herein,
unless specifically authorized by the Commissioner of Agriculture.

7B-33.03 Requirements for sale.--

(1) All potatoes
must meet U. S. No. 1,
that the tolerance for
for U. S. No. 2.

to be sold for propagation In Florida
or U. S. No. 1, Size B, requirements except
shatter bruising may be that designated

(2) All potatoes to be sold for seed in Florida must have
been grown under a seed potato certification program of the state


or country of origin, and each bag must be accompanied by a certi-
ficate issued by the agency administering the seed potato certi-
fication program.

(3) The Department shall have the authority to open any
shipment of seed potatoes for Inspection, and to draw a reasonable
sample from any bag of seed potatoes for laboratory examination
or for planting for field observation.

(4) Seed potatoes offered for sale in Florida must not exceed
the tolerances indicated for the following plant pests:

Golden nematode 0%
Potato rot nematode 0%
Potato wart 0%
Stem and bulb
nematpde 0%
Ring rot 0%
Spindle tuber 1%
Black leg 1%
Fusarlum wilt 1%
Net necrosis 1%
Late blight 1%
Any other dangerous
pest of potatoes
not listed 0%
Scab and Rhizoctonia same as
U. S. No. 1 tolerance

7B-33.04 Exemptions.--Nothing in this regulation shall prohibit
the sale for propagation by a grower to another grower, potatoes
or parts thereof grown in Florida or imported under the provisions
of this regulation, provided that the buyer has personal knowledge
of the condition of the potatoes at the time of sale with regard
to grade or plant pests for which there is a tolerance.

7B-33.05 Disposition of seed potatoes not meeting above require-
ments.--Seed potatoes not meeting the requirements for propagation
as specified in this regulation must be disposed of in a manner
approved by the Commissioner of Agriculture. He may order them
destroyed, treated, regraded to comply with this regulation, sold
for food, or removed from the State.

7B-33.06 Seed Potato Advisory Committee.--
(1) The Commissioner of Agriculture shall appoint a Seed
Potato Advisory Committee composed of five members--three from
the Florida Potato Council (two of which must be growers), one
from the Institute of Food and Agricultural Sciences, University
of Florida, and one from the Division of Plant Industry.

(2) The Committee shall meet on call of the chairman, to
be elected by the Committee. It shall be the responsibility of


the Committee to make recommendations to the vegetable industry
representative of the Plant Industry Technical Committee, Florida
Department of Agriculture, concerning legislation affecting the
Florida potato Industry, and to the director of the Division of
Plant Industry concerning the administration of the seed potato

EXPLANATION: The potato growers requested a regulation to help
protect them from low quality seed potatoes being shipped into
Florida because no specific plant pest standards existed for this
crop. The standards established by this regulation are those pre-
scribed by most good seed potato certification programs and should
assure high quality seed for our growers.

2. Table Stock Potatoes Used for Seed

In the fall and winter of the 1968-69 growing season there
has been two instances where growers have used table stock potatoes
for seed to plant several hundred acres with disastrous results.
One was planted In the fall on organic soils and another in mid-
winter on sandy soil; potatoes were from different areas of the
country and of different varieties. These potatoes had been treated
with a sprout inhibitor, probably chloro-IPC, before storage.
This is a normal practice In the fall harvest areas of the north.
These potatoes failed to germinate properly and those that did
were weak and plants did not grow off normal, Many plants actually
had leaf marginal burn and terminal bud Injury. This Is a reminder
to potato growers to never use potatoes for seed that have been
treated with a sprout inhibitor, been stored in a place where
sprout inhibitor was used on previously stored potatoes or in
bags previously used for treated potatoes.

3. Cucurbit Seed Treatment for Rodent Control

For many years we have used here in Florida a seed treatment
on watermelons and other cucurbits that contained Endrin. With
the removal of Endrin from use on most vegetables because of the
detection of residues by Food and Drug Administration analysis,
we were reluctant to continue to recommend this seed treatment
containing Endrin. The following information makes it appear to
be allowable. In addition, an effective substitute has been found.

Mr. Harold G. Alford, Assistant Director for Registration
of USDA, ARS Pesticides Regulation Division, Washington, D. C.
has this to say in a letter to Jim Brogdon, Extension Entomologist.


"It was my understanding that you wish to recommend the use
of 0.8 ounces of 50 percent wettable powder in treating 5 pounds
of watermelon seed.

"From what we can learn about the seeding rates, we would
conclude that this use would result in less than 0.1 ounces of
actual endrin per acre. We do not believe that watermelons grown
from such treated seed could reasonably be expected to contain
residues resulting from misuse. I have discussed this with Mr.
Frank McFarland and he concurs with this position."

In work done by C. A. Thomas at Clemson University with
Substitution of Aldrin for Endrin in the Watermelon Seed Treat-
ment Kit, the following results were reported.

"In all cases the Aldrin seemed to work as well as the Endrin.
No farmers reported damage where they used the Aldrin Kit. In
one field in Hampton County where no seed treatment was used,
mice caused severe damage. In Allendale County, County Agent
Funchess reported that he does not know of any watermelon growers
who do not use the kit. In a cantaloupe field In this county,
no treatment was used and mice caused severe damage.

"We also compared fields where the old Endrin Kit had been
used and no difference was noticed between this and the Aldrin
Kit. No strychnine treatmentsrwere used. All dealers contacted
said it was too much trouble to handle this and consequently all
used the Aldrin Kit.

"From these observations I think that I could safely say
the Aldrin Kit for Watermelon Seed Treatment does a good job and
should be recommended for the next season."
