THE GLADIOLUS FANCIER’S 

ROTOTOX 
The Penetrol spray made with Rotenone, 
containing also 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. We have numerous 
reports that its use has been highly satisfac- 
tory. Perhaps you have already seen the 
article by Dr. Roark, of the Dept. of Agricul- 
ture, 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, in addition to being a contact insecti- 
cide. Penetrol (oxidized petroleum hydro- 
carbon, sulfonated) is a carrier, spreader 
and activator. It is neither acid nor alkaline 
nor caustic, so the rotenone is held in perfect 
suspension, without precipitation or disin- 
tegration, thus making no disfiguring sedi- 
ment to mar or injure the most delicate foli- 
age or petals. Therefore, no need of segregat- 
ing early and late varieties. 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. 
Rototox contains Ethylene dichloride, 
which has for many years been used by many 
large growers for gassing their bulbs in storage 
quarters. This ingredient is valuable be- 
cause it reaches many insects not contacted 
and portions of the plant not fully covered 
by the spray. 
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 preventively 
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. 
The Rototox Co. has an excellent 20 page 
booklet containing much valuable insecticide 
information for all branches of horticulture.

“Ever since and including 1933, when I first followed your 
suggestion to use Rototox, I have used it every year with 
complete satisfactory results on gladiolus plantings ranging 
from small plots to two acres. A mighty profitable tip and 
many thanks.” 12-4-40. L. M. P., Twinsburg, Ohio. 
“Have used Rototox now for six years. This year I used 
it to treat the bulbs before planting in addition to the usual 
spraying and again had very good thrips control.’’ 11-5-40., 
H. E. B., Salem, Ohio. 
“T wanted to tell you that my asters were in a sad state, 
the leaves curling up and withering, and I sprayed them 3 
times with Rotorox mixture the same as I use for glads and 
they are now good healthy looking plants. Last year my 
hollyhocks were covered with rust. So this year I started 
spraying with Rototox when they were very small and each 
plant is clean and healthy. I am more than pleased with the 
results.”” 7-17-39. Mrs. E. H. S., York Harbor, Me. and 
Philadelphia, Pa. 
“Have been using Rototox now for three years. Found 
it very good.’ 4-3-’39. L. S. Miamisburg, Ohio. 
“Used Rototox on ten thousand glads and had fine results.” 
11-239. W.C., Schenectady, N. Y 
“T have used Rototox as a spray for three years and can 
truthfully recommend it to my friends. Thank you for 
recommending it to me.’’ 2-20-’39. F. W. S., Cleveland, Ohio. 
“T have been using Rototox for some years and it has 
proven very satisfactory in every way, especially for the 
control of thrips on Glads. Glad thrips are no longer a 
menace as I spray my Glads 2 or 3 times and forget about 
the thrips. I soaked my Glads in Rototox this spring and 
I note that they came up much quicker than when soaked in 
bi-chloride and seem to be much healthier looking.’’ 6-27-39. 
E. S. H., Lisbon, Ohio. 
“T have been fighting thrips and other insects on my roses 
for years. I have secured better control with ROTOTOX 
than with a dozen other insecticides. I spray 1-200 twice, 
24 hours apart. No more thrips until more are blown in. 
This may be 3 days or as many weeks. 
“I have no objection to your quoting me. You have a 
product that is very good. I would be glad for others to 
receive the benefit from it.’’ 11-23-37. Mr. Clapp, State 
of Texas Park Board. 
“IT used ROTOTOX on about 10,000 gladiolus as as 
means of getting rid of thrips. It proves very successful in 
this. In fact, I will consider it the equal if not the superior 
of any other treatment we have ever used for that purpose. 
Found it effective also against silver fish and cockroaches. 
also as a fly and mosquito killer. I have taken occasion 
to recommend Rototox through my newspaper syndicate 
and have recommended it perhaps a dozen times before 
various garden clubs where I have lectured. Will use as 
dip when bulbs are dug.’ 9-29-37. (Dr.) Floyd Bralliar,
