ATLACIDE is a proprietary compound patented 
by the Chipman Chemical Company. It contains 
Sodium Chlorate and other salts compounded in 
a manner to reduce the flamability of Sodium 
Chlorate. In tests over a three year period the 
average percentage of kill from the two chemi- 
cals was practically identical. May be applied 
as a spray or in original powder form. 
Price: (100-lb. drum $12.00). 
DDT PRODUCTS 
(Dichloro-dipheny]-trichloroethone) 
During the war DDT proved of value to the 
armed forces in all corners of the earth. And in 
its peacetime job in different formulations it has 
found its way into orchards and farms, home 
gardens and in household uses. On farm animals, 
in dairy barns and outhouses it has proven very 
useful in control of most common pests.

24-D PRODUCTS 
2,4-D (Dichloro Phenoxyacetic Acid) has become 
one of the important chemicals for control of many 
weed species. It is selective in action and this is 
its strength or advantage as well as its weakness 
or disadvantage. This selective action permits its 
use for treating weeds in grain crops, in grass 
seed crops, on turfs and pastures. At no time 
should the application be made to grain or grass 
after flower stalks have started to emerge from 
the boot. 
2,4-D is available in different strengths and forms, 
Liquid, Spray Powder and Dust, for different places 
and uses. 
Sodium Salt Spray Powder is a convenient form. 
Is more easily handled and more economical. 
Triethanolamine Salt in liquid form has the 
same uses as 2,4-D Powder. Is readily mixed in 
water and can be used at relatively high concen- 
trations for low volume spraying, either as a selec- 
tive or in general weed control.

COLORADO 44 INSECTICIDE made with Chlor- 
dane has been thoroughly tested and is fully 
guaranteed by the formulator. It is a crop-safe 
insecticide even to such delicate crops as squash 
and melons. It is superior to any similar type 
insect killer for truck gardens, household use and 
control of livestock parasites. 
The kill of grasshoppers and other crop infesting 
insects with Colorado 44 has been remarkable. It: 
is non-toxic to man or animal when properly ap- 
plied. The killing effect lasts for weeks. Colorado 
44 kills by contact, by ingestion and by vapors. 
Economical, easy and safe to use. 
COLORADO 44 DUST (5% Chlordane). (l-lb. dust 
guns 89c) (5-lb. bags $1.95) (50-lb. bags $7.00) 
COLORADO 44 EMULSION CONCENTRATE (Water 
Soluble, 44% Chlordane) (4 oz. bottle 75c) (8 oz. 
bottle $1.25) (pt. $2.25) (qt. $3.75) (gal. $11.00) (5 
gal. pails $51.50.) 

Ester Liquid is Isopropyl Ester. It is particularly 
useful and recommended for control of so-called 
hard-to-kill perennials, both woody and herbaceous 
plants and on plants that are difficult to wet be- 
cause of waxy foliage. Is diluted with oil and 
should not be used on cereal crops. 
2,4-D Dusts have advantages for control of 
annual weeds and certain perennials on account 
of more ease of application and where water is a 
problem. They increase the hazard from drift onto 
susceptible crops and may be less effective when 
applied during prolonged dry season. Acid Dusts 
and Isopropyl Ester Dusts are available. Their 
uses would be the same as the corresponding 
Powders and Liquids. 
Prices on larger sizes will be given on applica- 
tion. No statements are made for strength, quality 
or performance beyond what is in the manufac- 
turers’ labels, all of which are registered in each 
state. Bulletins on any or all of these products sent 
on request.
