Don’t forget a dormant spray this winter 
MICHELL’S INSECT DESTROYERS, ETC. 
Lemon-Oil Insecticide 
A standard insecticide used by the leading 
florists, nurserymen, and private gardeners 
who recommend its use for destroying lice, 
spider, thrip, black and green fly, mites, ants, 
aphis, and mealy bug. For mealy bug, the 
application should be applied with sufficient 
force to penetrate the protecting covering. 
Where one application is not effective repeat 
the treatment as often as necessary. 
Having no odor, it is especially desirable to 
use on all house plants, having this great ad¬ 
vantage over all soap and tobacco prepara¬ 
tions, which leave a disagreeable odor or 
greasy appearance. 
Does not injure the plant or bloom when 
used as directed and does not disfigure them 
as a powder will. 
It is non-poisonous, when used as directed 
and is therefore safe to both user and plant. 
Success depends on thoroughness and using 
the proper material. Succeed with Lemon- 
Oil Insecticide. It has been in use for over 
fifty years. 
Use Lemon-Oil Insecticide in the green¬ 
house on all plants; especially adapted to use 
on roses, carnations and chrysanthemums for 
many insects that infest them. Nothing can 
equal it for washing ferns, palms and rubber 
plants. 
J^Pt. 30c.; 50c. per pt.; qt. 85c.; $1.50 per 
%gal.; gal. $2.50; $10.00 per 5-gal. keg. 
LIME-SULPHUR. Dry. A convenient ma¬ 
terial for effective control of San Jose 
scale, apple and pear scab, peach-leaf curl, 
cherry leaf-spot. Lb. 35c.; $1.40 per 5 lbs.; 
25 lbs. $4.25; $8.00 per 50 lbs.; 100 lbs. 
$14.00. 
Concentrated Lime-Sulphur 
Solution 
The old, reliable, and most generally used 
insecticide and fungicide for spraying fruit 
trees. 
Apple Scab Control 
The use of Lime-Sulphur Solution to con¬ 
trol scab is one of the most important opera¬ 
tions in raising apples. However, it is usually 
combined with other materials to control 
more than one thing with the same spray 
such as: 
Delayed Dormant: 1 part to 20 parts water 
with Mechling’s Stabilized Oil Emulsion to 
control scab, scale, red mite, and aphis. 
Prepink: 1 part to 40 parts water—scab. 
Pink Bud: 1 part to 40 parts water plus 3 
pounds Arsenate Lead Powder—scab, cur- 
culio, canker worms, tent caterpillars. 
Petal Fall: 1 part to 50 parts water, plus 
3 pounds Arsenate Lead Powder—scab, 
codling moth, curculio. 
When Lime-Sulphur Solution is used in the 
summer sprays, great care must be exercised, 
the dilution being 1 to 60 or weaker. 
Peach-Leaf Curl 
Use a dilution of 1 to 9, either in the fail 
after leaves have dropped or in early spring 
before buds begin to swell, to control peach- 
leaf curl. 
San Jose Scale and Aphis 
At the delayed dormant period use Lime- 
Sulphur Solution, 1 to 9, to control San Jose 
scale. Add \)/t pints Black-Leaf 40 to 100 
gallons this solution to control aphis at the 
same spray. In some localities, San Jose scale 
seems to be becoming resistant to Lime-Sul¬ 
phur, in which case, or if infestation is heavy, 
use Mechling’s Superior Scale Oil or Stabil¬ 
ized Oil Emulsion. 
Qt. 45c.; $1.00 per gal.; 5 gals. $4.00; 
$9.50 per J^bbl. (30 gals.); bbl. (55 gals.) 
$13.00. 
LORO 
A contact Insecticide 
Loro has been thoroughly tested under 
practical greenhouse and field conditions and 
in commercial growing areas in many parts 
of the country and has proved useful on 
chrysanthemums, carnations, snapdragons, 
gladiolus, certain ornamentals and shade 
trees. Under commercial growing conditions 
the following advantages of Loro have been 
proved: 
Kills mealy bug, chrysanthemum midge, 
red spider, thrips and aphids (green fly, black 
fly), and the eggs of red spider, midge, mealy 
bug as well as active stages of the insects. 
Does not stain blooms or spot foliage of 
carnations, nor deposit unsightly residues on 
foliage of floral crops. 
Effective at ordinary temperatures (60° F. 
to 75° F.). 
Compatible with most other common in¬ 
secticides and fungicides excepting those 
containing sulphur. 
Free from objectionable odor in dilute 
spray solution. 
Growers have found that Loro has very 
distinct ovicidal or egg-killing powers, particu¬ 
larly in the control of mealy bug, red spider, 
and chrysanthemum midge. When insect 
eggs are killed, reinfestation is definitely 
slower and over the period of a crop season 
fewer sprays are required to maintain a clean 
crop. The resulting saving in labor is an 
important advantage. 
Pt. $2.00; $9.75 per gal.; 5 gals. $43.75. 
Mexican Bean Beetle Destroyer 
Dust or Spray 
Will quickly kill Mexican bean beetles 
without danger of burning foliage and is 
recommended by most agricultural experi¬ 
ment stations. Mexican Bean Beetle De¬ 
stroyer contains magnesium arsenate and is 
ready to use as it comes from the package as 
either a dust or spray. 
Application Important 
Regardless of whether spraying or dusting 
is practiced, application must be made to the 
undersurfaces of the bean leaves as soon as 
eggs or insects are first noticed, and repeated 
at 7 to 10-day intervals. Initial appearance is 
usually when plants begin to send out their 
first trifoliate leaves. From one to four appli¬ 
cations may be necessary for a crop of bush 
beans. 
Mexican Bean Beetle Destroyer requires 
the addition of no other material when used 
as a dust. For wet spraying mix 8 pounds to 
100 gallons of water or 6 level tablespoonfuls 
to 1 gallon of water. Mix the required amount 
of material with a small quantity of water to 
form a smooth paste, and then add remainder 
of water and agitate thoroughly while spray¬ 
ing. Lb. 35c.; $1.25 per 4 lbs. 
MEXOGEN. Kills and repels Mexican bean 
beetles. Non-poisonous to humans, ani¬ 
mals, and birds, when directions are fol¬ 
lowed. j^pt. 75c.; $2.00 per qt.; gal. $6.00. 
MO-LO. For destroying and driving away 
moles. Pkg. 25c. 
MOLOGEN. Eliminates moles from the 
lawn within 2 or 3 days. Non-poisonous to 
humans or pets. J-^-Ib. can 50c.; $1.25 per 
1 J'i-Ib. can; 5-lb. can $4.00. 
MOUSE SEED. Safer and more convenient 
than paste or traps. Ready to use. No 
bait required. Pkg. 25c.

Nico-Fume 
Protection against greenhouse insects is 
assured when Nico-Fume Products, Liquid, 
Paper or Powder, are used. Nico-Fume 
Products have for years been the choice of 
American florists for killing aphis, thrip, leaf 
hopper, etc., in their wonderful ranges of glass 
where delicate flowers and plants are grown. 
Nico-Fume Products are made by the world’s 
largest manufacturer of nicotine insecticides, 
and are safe, dependable, and effective. 
“Fumigation Reaches All Leaves and Buds” 
Nico-Fume Liquid 
A powerful and highly refined nicotine solu¬ 
tion that has the twofold advantage of being 
adaptable either for spraying or for fumigat¬ 
ing purposes. 
For Fumigating. Use 1 fluid ounce to 
each 4000 cubic feet of air-space, when vapor¬ 
ized in lamps, or on steam heating pipes. The 
liquid may be poured on steam pipes from an 
oil can with a long spout, thus furnishing a 
quick, easy method of controlling insects. 
For Spraying. Effective when diluted at 
the rate of 1 or 2 teaspoonfuls to each gallon 
of water. For more resistant insects such as 
black fly (aphis), leaf-miner on “mums,” etc., 
3 or 4 teaspoonfuls to each gallon of water 
may be used. 
Lb. $2.50; $6.00 per 4 lbs.; 8 lbs. $11.00; 
$45.00 per 40-lb. drum. 
Nico-Fume Paper 
Consists of sheets of paper, chemically 
treated with a definite amount of high- 
strength nicotine. T he sheets are suspended 
from one end and lighted from the other end. 
They burn freely, giving off dense nicotine 
vapors which are deadly to insects, but are 
free from the harmful effects of tobacco 
smoke. 
Nico-Fume products are especially suitable 
for fumigating roses, chrysanthemums, lilies, 
carnations, etc. 
Box of 24 sheets, $1.50; $4.75 per 144 
sheets; 288 sheets $8.50. 
Nico-Fume Powder 
Many florists prefer a tobacco powder for 
fumigating. Nico-Fume Powder (patented) 
consists of tobacco powder impregnated with 
high-strength nicotine and is guaranteed to 
contain not less than 12per cent of nicotine 
by weight. 1-lb. can $1.15; $3.50 per 5 lbs.; 
10 lbs. $6.25. 
Nico-Fume Pressure Fumigator 
Nico-Fume Pressure Fumigator is safe for 
the plants and is the most commonly used 
fumigant. Insects on crops grown in green¬ 
houses may be controlled by fumigation in 
many instances. This is advantageous to 
greenhouse owners because fumigation reaches 
every leaf and bud, and requires less time and 
labor than does spraying. 
J^-Ib. size, 45c. each; $2.40 for 6; case lots 
of 1 doz., $4.20.
