II. Pesticide Update

A. EPA Restricted Use Pesticides On The Market

The accompanying table provides the names of pesticide active in-
gredients for which some or all formulations have been classified by
EPA as restricted, to limit their use and purchase to certified appli-
cators or those working under their direct supervision.
When considering purchase and application of specific product con-
taining one of these pesticides, always check for restricted use
statement on the label. For certain pesticides (such as chlorobenzil-
ate, endrin, and heptachlor), most registrations have been cancelled;
very few uses remain.

The sample trade names in parenthesis are provided only to allow easi-
er identification of common names.

III. Commercial Vegetables

A. Use of Agricultural Plastics in Florida

Florida is the second leading fresh market vegetable state in the
nation with approximately 400,000 acres of vegetables. Plastics play

a large part of nearly every facet of the Florida vegetable industry.
The use of polyethylene mulch began in the late 1950's, and today
is used on about one-fourth of the state's vegetable acres. Nearly
100 percent of the tomato and strawberry crops, and 75 per cent of the
pepper, cucumber, and eggplant crops are produced on the full-bed
mulch system. Black polyethylene mulch is the predominant type used,
although some white-on-black and black with gray center bands are used
for fall crops.
Another large user of plastics is in the vegetable greenhouse in-
dustry both for vegetable transplant production and for crop produc-
tion. Polyethylene is used for greenhouse coverings and various plas-
tics are used for greenhouse coverings and various plastics are used
for growing trays and containers, irrigation systems, containers for
bag and nutrient-film crop production techniques, and for packaging.
Drip irrigation, a system based on plastics, is an established
practice in some vegetable producing areas in Florida. There are over
3200 acres of Florida vegetables produced using drip irrigation and
this is increasing. Drip irrigation is used mainly on tomatoes, pep-
pers, watermelons, and strawberries.
Vegetable harvesting and packaging utilizes a large amount of
plastics in Florida. Plastic items used include field picking con-
tainers for most crops and pint baskets for strawberries and cherry
tomatoes. Vegetable packaging uses plastics for film wrapping of
lettuce and cauliflower, and mesh bags and film bags for packaging of
onions, carrots and radishes. Plastics also are used in the packaging
of products consumed by the Florida vegetable industry such as seeds,
fertilizers, and pesticides.
The future for agricultural plastics in Florida is promising.
There is potential for increased use in all areas mentioned above. In
addition, new uses for plastic, such as row covers for growth enhance-
ment and frost protection are being evaluated.
Much of Florida's present-day agricultural plastics technology
has evolved from research conducted by various units in the University
of Florida's Institute of Food and Agricultural Sciences. These re-
searchers interact at all levels within the Florida vegetable industry
and with fellow research and extension colleagues in the National Ag-
ricultural Plastics Association (NAPA). The basic theme of NAPA is to
promote the exchange of research results on the use of plastics in in-
tensive crop production systems. The NAPA Congress meets nearly every
15 months and publishes a proceedings and newsletter. For more infor-
mation concerning NAPA and the upcoming 1986 Congress, contact: Dr.

B. Cucumber varieties for Florida

Variety selection, often made several months before planting, is
one of the most important management decisions made by the grower.
Failure to select the most suitable variety or varieties may lead to
restricted yields or poor market acceptability.
The following characteristics should be considered in selection

of cucumber varieties for use in Florida:
*Yield the variety selected should have the potential to produce
crops at least equivalent to varieties already grown. The average
yield in Florida of slicing cucumbers is currently about 300 bushels
per acre while the pickling cucumber yield is about 160 bushels per
acre. The potential yield of varieties in use should be much higher
than the average yields shown above.
*Disease Resistance varieties selected for use in Florida should
have resistance to angular leaf spot, anthracnose, cucumber mosaic,
downy mildew, powdery mildew, and scab. Available resistance to other
diseases may be important in certain situations.
*Horticultural Quality Vine habit, flowering habit, fruit color and
shape, and spine color may affect the variety selection decision.
*Adaptability Successful cucumber varieties must perform well under
the range of environmental conditions usually encountered in the dis-
trict or on the individual farm.
*Market Acceptability The cucumber produced must have horticultural
and maturity characteristics acceptable to the packer, shipper, whole-
saler and consumer. For pickling cucumbers produced for processing
either on contract or for sale on the open market, variety selection
is usually dictated by the processor according to the intended use of
the pickle.
With all of these, and perhaps other considerations, it is appar-
ent that serious thought must precede variety selection.

Cucumber Variety Terminology
Several unique terms are used, either singly or in combination to
describe cucumber varieties. An understanding of these terms is es-
sential as they are related to seed costs, earliness, pollination and
other production practices.
*Open-pollinated variety A true-breeding variety with separate stam-
inate (male) and pistillate (female) flowers on the same plant. Tech-
nically, this condition is called monoecious. Poinsett 76 is an ex-
ample of an open-pollinated, monoecious slicing cucumber variety.
*Hybrid variety A variety produced by crossing two unrelated parent
cucumber lines. Hybrids are not true breeding, so new hybrid seed
must be produced for each crop by crossing the unrelated parents. Hy-
brids may be monoecious or gynoecious (see below): 'Saticoy Hybrid'
is an example of monoecious hybrid.
*Gynoecious All of the flowers produced on gynoecious hybrids are
female, therefore they are sometimes referred to as "all-female hy-
brids". Since no male flowers are produced for pollination, a small
number of monoecious seeds are blended into the seed lot by the seeds-
men to provide for adequate pollination. The pollinator is carefully
selected to produce fruit similar to the gynoecious type so that they
can be marketed together. Gynoecious hybrids are often earlier than
monoecious hybrids, but total yield may not be greater. 'Dasher II'
is an example of a gynoecious hybrid slicing cucumber.
*Parthenocarpy European greenhouse cucumber varieties grown in the
absence of bees develop without pollination, and therefore are seed-
less. These same varieties grown in the field in the presence of bees
will not be parthenocarpic or seedless.

IV. Vegetable Gardening

A. Varietal Selection of Tomato Plants Available in Stores.

Throughout the state of Florida few home gardeners have heard of
such tomato variety names as 'Duke', 'FTE-12', 'Hayslip', 'Horizon',
and 'Sunny'. These varieties are commonly grown by the commercial
farmers in a state which leads the nation in the production of this
popular salad vegetable.
Surely these high-yielding plants will produce just as many toma-
to fruits in the garden as in the field, so why aren't they grown
there? The explanation is fairly simple. First, these are relatively
new varieties, so gardeners just haven't gotten word of them as yet.
Secondly, plants just aren't offered for sale in garden seed and plant
stores, and gardeners do prefer to set plants rather than start from
seeds in most cases.
To determine just what varieties are available in garden supply
stores from which gardeners may choose for their gardens, we conducted
observational trails based just on those varieties that were offered
on the store shelves in three north Florida cities Tallahassee,
Jacksonville, and Gainesville.
Tomato varieties which we (Extension) feel are well-suited for
planting in home gardening situations throughout the state are listed
in The Planting Guide for Vegetable Gardens, and in Fact Sheet 75-8,
Tomatoes in the Florida Garden and Extension Circular 104. However,
due to space limitations, only a select few can be mentioned. There
are many others which might and should be listed. For example, the

varieties developed at the Bradenton AREC for use in container cul-
ture, such as Florida Basket, Florida Lanai, and Florida Petite, are
recommended but are not in these guides.
Let's now take a look in the following table at currently recom-
mended varieties and see which ones were actually available as trans-
plants for sale on the shelves of stores surveyed in the three cities

Information in the table should be looked at with care before
conclusions are drawn. Keep in mind that these were the offerings at
a very limited number of garden supply stores (3) at a precise time of
day. While this information reflects what is available to gardeners,
it is not totally representative. Plants of other varieties might
show up at other times and other places.
However, the table does show that of the 26 varieties currently
in Extension guides for gardeners to try, 10 varieties were available
in all three cities during the prime planting month of March. Furth-
ermore, plants of 40 varieties of which 14 were recommended varieties
were found in stores in at least one of the North Florida cities.
That represents a fairly good selection of plant material for garden-
ers in Florida. Of course, many gardeners prefer to purchase seeds
and start their own plants.
Those plants which were found for sale at the local stores were
planted and evaluated. A report on the preformance will be forthcom-
ing after a repeat of the trial in 1986.
