THE GLADIOLUS FANCIER’S 
ings about 4 days apart beginning about 20 
days before blooming, i.e., about when the 
bud spikes begin to fatten the stalk. If an 
infestation is actually present, use full 
strength concentration. 
You will notice that we have gone to 
greater expense to place all this valuable in¬ 
formation in your hands than in effort to sell 
you gladiolus bulbs. We know, if you are in¬ 
terested in glads and have taken the trouble 
to read it all, that you appreciate the infor¬ 
mation. It may be the means of turning your 
failures into success, or keep you from pos¬ 
sible dissatisfaction with gladiolus through no 
fault of the glads, themselves. Kindly re¬ 
member there are other dealers who may save 
money by omitting modern safeguards to 
their bulbs while growing and while in stor¬ 
age, and save some more by letting others 
keep your information up to date. They may 
save enough to price a bulb a penny lower in 
some instances, but we believe, even in such 
event, we may offer you better bulb value, 
penny for penny. 
ROTOTOX 
The Penetrol spray made with Rotenone 
and Pyrethum, containing also Acetone and 
Ethylene Dichloride, in fact a full 90% of 
active ingredients. 
We have been investigating the value of 
the new insecticide called “Rototox” with a 
view to its substitution for all home-made, 
assembled formulas, as a complete spray in 
itself for all general purposes and for gladi¬ 
olus in particular. The results are almost too 
amazing to be readily believed. Let doubters 
try it and be convinced. Perhaps you have 
already seen the article by Dr. Roark, of the 
Dept, of Agriculture, who considers Rotenone 
(derived from derris or cube root) one of the 
most effective insecticides available, being 
fifteen times as effective as nicotine and 
thirty times as effective as arsenate of lead. 
Rototox, while so deadly to insects, is 
non-poisonous and perfectly harmless to 
humans, animals and plants and fruit and 
vegetables sprayed with Rototox may be 
eaten with perfect safety within 24 hrs. after 
spraying. The Rotenone acts as a stomach 
poison to insects as long as it remains on the 
plant, while the Pyrethum acts as contact 
insecticide. Penetrol (oxidized petroleum 
hydrocarbon, sulfonated) is a carrier, spreader 
and activator. It is neither acid nor alkaline 
nor caustic, so the rotenone and pyrethum 
are held in perfect suspension, without pre¬ 
cipitation or disintegration, thus making no 
disfiguring sediment to mar or injure the most 
delicate foliage or petals. It causes the for¬ 
mula to emulsify as readily and completely 
in cold, hard water as in warm, soft water. 
It does not have to be kept agitated and it 
cannot clog the spray nozzle. These are the 
reasons why Penetrol is known as the best 
spreader for carrying the formula into the 
crevices of the plant, an extremely desirable 
feature for the control of thrips. 
At Century of Progress grounds, 1934, there 
was planted four large plots of beds of gladi¬ 
olus by about 20 growers. (We participated). 
Laid end to end there were 6 miles of rows of 
gladiolus. Rototox was used preventatively 
on all these beds with very satisfactory 
results. 
Rototox has already become popular for 
greenhouse use and is cheap enough for use 
on large acreages of gladiolus, dahlias, per¬ 
ennials, evergreens, truck crops, etc. 
We do not stock Rototox. You can get 
what you need promptly (much quicker than 
by asking us to relay your order), postage pre¬ 
paid, from 
"Rototox,” 
81 East Yale St., 
East Williston, N. Y. 
Their prepaid prices (no doubt subject to 
change) are: 1 oz., 35c; 8 oz., $1.00; 1 pint, 
$1.75; 1 quart, $3.00; 1 gal., $10.00; 5 gal., 
$45.00. 
At the strong concentration for bad infesta¬ 
tions, 1-200, 1 gal. will make 192 gallons of 
spray. At suggested preventative concentra¬ 
tion, 1-400, 1 gal. will make 384 gallons of 
spray. (About 5c or 2j^c per gal., depending 
on concentration needed.)
