Manalee is a highly productive, early maitriing tomato variety of good qual-

ity, especially adapted for fall crop production in the Mahatee-Ruskina and other:

areas of the southern half of Florida. Manaleo is inherently resistant to the

following fungus diseases: (1) Fusarium wilt, (2): Gras loaf spot, (3) Early

blight, sore-shank, and collar-rot, and (4) Leafmold. In additi6i-too the resis-

tance to those four common diseases, Manaloe has otho, advaA-tdgeo over the vario-

ties now considered commercial standards. The variety was released r1boitly by

the Gulf Coast Experiment Station and a full description will be available in a

Florida Agricultural Exporiment Station Circular in due course.

Manaloe was developed by line breeding from stocks developed for resistance

to Fusarium wilt at this station and stocks supplied by the Southeasteri Regiohal

Vegetable Brooding Laboratory. The latter were used as sources of resistance to-

collar-rot and leafmold. Manalee is the result of fortunate combinatto0 of dedir-

able traits from disease-resistant parents that could not, themhoelveds, qualify

as horticulturally acceptable varieties. Earliness and dmoothWesa oif fruits

wore kept in mind as traits of prime importance at each step' in the several gen-

orations of selections that were required to fix the desired type'.j

Under the temporary designation VOL #11, Manalee has been tested in yield

trials for several years in widely separated areas. In tests on which fungicides

were applied on regular schedule to protect disease-susceptible varieties planted

for comparison, Manalee has been shown to be superior in earliness and yields.

Manaloe is an early maturing variety, not quite as early as Manasota but

often several days earlier than Grothon's Globe. The fruits of Manalee are of

medium size (approximate average .28 lbs.) with attractive smoothness and depth.


At mature green stage fruits are light green in color and they ripen uniformly

to full red color. All records indicate that the fruits withstand modern har-

vesting and processing operations well. .:

Internal characteristics: The fruits show an average number of locules and

have a firm gel. Walls are medium in thickness and firm of texture.

Manaloo is resistant to radial and concentric cracking and is usually re-

sistant to cat-facing. There is evidence that the fruits are moderately resis-

tant to blossom-end rot. For those reasons, harvest yields usually show a large

percentage of U. S. No. 1 fruits.

Horticultural characteristics: The vines are open, but stems and leaves are

larger than those of Grothen's Globe and W.R.Grothen Globe plants. If Manalco

is grown on stakes in the spring crop season it is advisable to prune the plants

only once or twice as the plants are not excessively vigorous.


Fumigation, fertilization, bedding and "boarding-off" becomes one efficient

operation with this equipment. Obviously, the satisfactory use of this type of

dispenser attached to a Georgia stock requires that the draft animal walk at a

steady pace.

A comparison was made between a single line of fumigant and two lines

one foot apart, with the total dosage per acre the same. No difference in yields

resulted, but rootknot was less severe where the single line of material was used,

Though some growers have constructed apparatus for delivering two streams to the

beds, no data indicating any advantage in this have been available.

Soil that is to be treated with a fumigant should be well worked, and

the upper 6" should be free of undecomposed plant material. Application of the

f.nigant is normally made on the original soil surface, with the fertilizer, anrr

a bed 6"-8" high thrown immediately over it. The top of the bed should be com-

pacted or "boarded-off" to seal-in the material. If the soil is dry and hot at

time of treatment much of the fumigant will be lost quickly by evaporation. In

order to obtain the maximum benefit from the fumigant it is desirable that rain

sufficient to seal the soil surface fall immediately after application; growers

equipped with an overhead irrigation system can make good use of it for this

purpose. For those who do not have sprinkler equipment and can not arrange to

complete the treatment of a field just before a shower, it is advisable that appli-

cation be made when the soil is at the highest moisture content permitting


For crops grown on flat surface without any bedding, the fumigant should

be applied 4" under the surface behind a bull tongue or small shovel and a drag

to smooth and compact the surface should follow immediately behind the applicator,

Soil treatment on a small scale for the home gardener may be accomplished

by the use of a quart jar arranged with a delivery tube (Fig. 2).
