New varieties are periodically compared with
current varieties in field tests conducted by state
experimental stations. The following list is a
partial listing of varieties which have performed
well in Florida. Most of the open pollinated, stand-
ard varieties bear male and female flowers (mon-
oecious). Many of the newer varieties, with higher
yielding and disease resistant characteristics, bear
mostly female flowers and are called gynoecious

,ucumbers are susceptible to injury from root-
ot and sting nematodes. Soils known to be
ivily infested with these nematodes should be

;, etc., are possible means of controlling nema-
es. If soils heavily infested with plant parasitic

nematodes must be used, they should be fumi-

Since fertilizer rates, sources and placement
or unmulched and strip-mulch culture differ con-
iderably from full-bed mulch culture, information
or each is presented separately. A soil test should
e made as soon as the production field has been

art I. Production Under Unmulched or Strip- Mulch
Placement-Recommendations in the past for
pen culture have been to place the main or basic
plication of fertilizer normally used at planting
bands 2 to 3 inches to each side and slightly
elow the level of the seed or plant roots. An al-
rnative practice, which helps alleviate soluble
It problems, is the use of bed-incorporated appli-
tions for part or all of the basic fertilizer before
Strip-mulch culture differs from the open meth-
in that only 20% of the fertilizer is bed-incor-
:rated and the balance is placed under an 8- to
i-inch strip of polyethylene mulch to reduce
Timing-The basic application of fertilizer may
Applied before planting, during planting, short-
after planting, or in split applications combin-
g any two or all three of these. Supplemental
rtilizer may be applied whenever needed during
e growing season and especially after heavy,
aching rain.
Soil pH-Optimum range for cucumber produc-
on is between 6.0 and 6.5. Where magnesium
vels are low, use dolomitic limestone.
Minor Elements-A general guide for adequate
inor elements, in the absence of past experience
soil tests, is the addition of 0.3% MnO, 0.2%
O0, 0.3% Fe203, 0.2% ZnO, and 0.2% B203 with
e fertilizer. The minor elements can be obtained
om mixtures of oxides and sulfates or fritted
materials. Growers should consider the elements
plied in fungicides in the overall management
a minor element program.
Higher rates are necessary to overcome the ten-
*ncy of minor elements to be completed or tied-
> by the high pH of marl soils.

Part II. Production Under Full-Bed Mulch
When using full-bed mulch without drip irril,
tion, the crop must be supplied all of its soil :
quirements (lime, fertilizer, soil pesticides, init
moisture, soil preparation and bed shape) befo
the mulch is applied.
The following are suggestions for fertilizati
under full-bed mulch culture. They should
modified as needed.
A general sequency of operations for full-b
mulch culture is: (1) land preparation, (2) li
ing, (3) addition of superphosphate, mixed fi
tilizers and minor elements to be incorporate
into the future bed area, (4) mixing insectici
into soil, (4a) incorporation of herbicide, if usi
(5) bed-shaping, (6) fumigation, (7) bed-firmi
and re-shaping, (7a) application of surface-i
plied herbicide, if used, (8) application of the b
ance of mixed fertilizer on the surface, and (
application of mulch. The following are guic
lines to rates, sources and placement of fertili2
for full-bed mulch culture.

Total major elements suggested per acre for
ull-bed mulch culture:
N P205 K20
00 to 200 lbs. 50 to 100 (old land) 120 to 240 lbs.
100 to 200 (new land)
Placement of the fertilizer materials may vary
somewhat. The following approach has been used
uccessively by growers.
(1) Broadcast and disk in:
(a) Superphosphate (20%) at rate of 400
to 600 lbs. per acre before fumigation.
(Vary amount depending on residual
(b) Minor elements-Use rates suggested
for unmulched production.
(c) Mixed fertilizer-300 to 500 Ibs. of 5-
10-10 or 6-12-12 per acre as a "start-
er." (Note-Alternative is to broad-
cast the starter fertilizer on the sur-
face just prior to applying mulch
cover.) At a between row spacing of
4 to 5 feet, apply about 4.5 lbs. of start-
er per 100 linear feet of bed. On rows
6 to 7 feet wide, apply about 5.5 lbs. of
starter per 100 linear feet of bed.
(2) Apply on bed surface:
Balance of fertilizer in two broad bands on
each side of a one-row bed or in three
bands on a two-row bed. A total of 500
to 1,000 lbs. of an 18-0-25 mixture can be
used here, depending on the length of
harvest season anticipated. At a between
row spacing of 4 to 5 feet, apply 12 lbs.
of fertilizer per hundred linear feet of bed.
With a 6 to 7 foot spacing, apply 14 lbs.
per hundred linear feet.
NOTE: Nitrogen should come primarily from a
trate source for soils that have been fumigated
id fully mulched. A ratio of 60 to 70% nitrate-
Itrogen and 30 to 40% ammonia-nitrogen is sug-
isted. Some natural organic can be added, but
iey will not convert readily in fumigated soil
atil nitrifying organisms return. For two or
iree bands, divide the total pounds of fertilizer
ir 100 feet of row by the number of bands used.

Weeds must be controlled during the initial
phases of cucumber production before the vines
cover the soil. Thorough soil preparation to con-
trol all weed growth before planting is essential.
After cucumber emergence, cultivate weeds when
they are small and easy to control.
The following herbicides are registered for use
in cucumber production. However, growers should
test these herbicides on a trial basis to become
acquainted with the weeds they control and th
proper methods of application. Read the herbicid
labels carefully and apply at proper time wit
proper soil or planting conditions.

The amount per acre of insecticides and fungi-
ides recommended under "Insect Control" and
'Disease Control" is for full-grown crops and
should be reduced proportionately for smaller
plants. "Minimum Days to Harvest" means the
minimum number of days that must elapse be-
ween last foliar application and harvest. If the
osages recommended are exceeded, the minimum
ays listed may not be applicable and a longer in-
erval should be allowed.
The amount of spray or dust required for ade-
uate coverage varies according to size of the
lants. Generally, 50 to 150 gallons of spray or 20
35 pounds of dust are sufficient for good cover-
ge. Pressure in spraying should not exceed 250
PRECAUTIONS: Pesticides should be used with
treme caution. Read the label and follow recom-
endations on crop to use, dosage and time lapse

baits should be applied late in the afternoon or early
evening hours. If applied early in the day, rain, ir-
rigation, heat and sunlight can reduce their effec-
tiveness. Since the cutworm moves very little, baits
applied in the row would probably give as good re-
sults as those broadcast. When spraying young
plants with most recommended insecticides, if noz-
zles are arranged so that the spray also contacts

so, perhaps more strong consideration should be
given for treatment.

Use high rates of materials for organic soils.

Apply all wireworm soil insecticides 2 weeks prior
to planting. Distribute evenly, cross-disc into the
soil preferably to a depth of 6 inches.

Apply labeled mole cricket bait late in the after-
noon for the same reason as discussed under cut-
worms. Mole crickets do not accept bait unless night
temperatures are in excess of 60*F. and the soil is
in a moist condition. Control of this insect is dif-
ficult or unlikely, even at best. Remember if any
control is to be expected, baits must be broadcast
and not applied in spots.

Diazinon spray used for cutworms (see instructions
under cutworms) has resulted in reduced mole
cricket problems.

Anthracnose, Downy Mildew, and Gummy Stem
ight-Downy mildew is serious in all parts of
e state during warm, damp weather. Spray every
to 7 days, beginning before runners start, if
cessary. In seasons of light infection, applica-
ins may be delayed until runners form and in-
:vals may be longer.
There are several varieties of cucumbers re-
itant to downy mildew but fungicides should be
ed to prevent other diseases.
Powdery Mildew-The fungicides used for
wny mildew give some control of powdery mil-
w, but most will not give sufficient control.
rathane, Bravo, and benomyl are effective. If
wdery mildew is a persistent problem, use one
the materials on a preventative basis: i.e., on a
,ular schedule (every 7 to 14 days) before the
ease appears. During cold weather, sulfur may
used to help control powdery mildew. Use sul-
in cold weather only 2 or 3 times at a maxi-
im rate of 2 lbs. per acre each time.
iruses (Mosaic)-Most mosaic symptoms in
se crops are caused by aphid-transmitted
uses that occur naturally in wild hosts. Elimi-
ion of weeds around the field before planting
1 help greatly in reducing losses from virus

Angular Leaf Spot (Pseudomonas lachrymans
-Use only disease-free seed.
Weekly applications of copper sprays (3 pound
of 48-53% metallic copper per 100 gal/A) help t
control spread of the disease in the field. Coppe
will not give satisfactory control of powdery mil
dew and this is not a substitute for the othe
materials. Repeated copper applications may caus
yellowing of leaf margins and possibly reduction
of yields. No time limitation when used as su

Bees are necessary for pollination of cucumber
Good pollination improves set, shape, and size
fruit. Use at least one hive of honey bees for evei
three to five acres of cucumbers. Place beehive
in the field so that bees do not have to travel mo:
than a hundred feet to feed.
Apply insecticides in late afternoon to avoid ii
jury to bees.

Harvesting extends from October to July an
normally begins about 45-65 days after planting
or 7 to 10 days after flowering. Season an
weather significantly affect plant growth an
picking frequency. Picking is necessary sever
times per week due to rapid increase in size, d
crease in quality and the need to remove all fru
to insure continued production of desired size
Cucumbers for slicing or pickling should be ha
vested before they have reached full diameter ai
while the seeds are small and soft. Increase
amounts of light green and yellow external col
indicate that seeds are no longer immature. Sli
ing cucumber texture should be firm and not so
and puffy.
Vines should be trained into the row to ke(
them out of the picker's way since stepping on t
vines greatly reduces yield. Cucumbers should
removed carefully from the plant to avoid dama
to the fruit and vine. By grasping fruit near t
stem, pickers can snap fruit from the vine by
slight twisting motion.

Cucumbers should be hauled to the packing-
house immediately after harvest to reduce water
loss, sunburn, and decay. To avoid bruising, they
should be handled in rigid containers such as bulk
bins or field boxes and not burlap bags, since im-
act and pressure can cause serious internal dam-
ge. Slicing cucumber fruit are washed, waxed,
ized, packed in cartons or wirebound crates, and
oaded directly in trucks for shipment. The U.S.
ancy grade for slicing cucumbers requires a
iaximum of 23/8 inch diameter with a minimum
ength of 6 inches, and a shape that is nearly
