DEVOE ARSENATE OF LEAD 
Pulp Form 
Paste Arsenate of Lead is better than government requirements in the matter of percentage of Arsenic 
Oxide. An effective insecticide chiefly for many of the Bugs, Worms and Moth that fruit. growers have to 
contend with. It comes in paste form and can be easily mixed with water. It forms a milky film when 
sprayed on foliage which does not readily wash off with rain. Good for potatoes and tobacco and all kinds 
of fruit trees. 
Arsenate of Lead is the most valuable of the arsenical poisons. It is a stomach poison and has three 
distinct advantages over other arsenical mixtures, which are: It is harmless to the foliage, it adheres 
better to the foliage, and it remains longer in suspension., The usual proportion is 3 pounds lead arsenate 
to 50 gallons of water. Weaker mixtures are often effective, while 5 pounds to 50 gallons of water may be 
an advantage in killing insects difficult to poison. It may be used with Bordeaux Mixture without diminish- 
ing the value of either 1 lb. Can 35c; 5 lbs. $1.60

DEVOE ARSENATE OF LEAD 
Dry Powdered Form 
The Perfect Insecticide. An effective insecticide for leaf-eating insects and particularly suitable 
for very tender foliage. Due to the light, fluffy character of this material and its adhesive qualities it 
insures quick and effective control. Under favorable conditions will not injure the foliage. Can be used 
on Apple, Pear, Peach, and Plum trees, Potatoes, Corn and Vegetables of all kinds that may be attacked 
by leaf-eating insects. 
Can be used either dry or as a spray. The person having a small garden and a few trees will find 
the dry method the more practical. 
Dust the trees or plants lightly, putting on just enough so that the foliage on close observation will 
show a luster of metallic tinge. Dust vegetables when the bugs first appear, using 4 to 5 lbs. to the acre. 
To control the corn ear worm dust the silk as soon as it appears. Treat each ear. The worm works only 
on fresh silk and works into the ear. For effective control keep the fresh silk treated. 
When used as a spray use 1 ^ to 2 lbs. to 100 gallons of water for trees and 2 to 2 }4 lbs. to 100 gallons 
of water for potatoes lb. 35c; 1 lb. 65c; 5 lbs. $3.00

CALCIUM ARSENATE 
Dry Powdered Form 
For the control of Potato Bugs. Calcium Arsenate is a lighter, more fluffy powder than Arsenate of 
Lead or Paris Green — more bulky. When used dry, will dust more plants per pound, and when mixed 
with water will stay in suspension better and give you better and more uniform distribution. Lead Oxide 
in Arsenate of Lead has no insecticide or fungicide value; but Calcium Arsenate is made on a lime base 
which has fungicide value. Lime adheres perfectly to foliage; will not wash off easily and is white. For 
protection against the potato bettle, cabbage and tobacco worms. 
For potato bugs and other large leaf eating insects, one to three pounds per acre dry, or 2 to 2 ^ lbs. 
to 50 gallons of water lb. 30c; 1 lb. 55c
