PROTECT YOUR TREES AGAINST UGLY, 
CRAWLING, STRANGLING CREATURES 
WITH 
Tree Tanglefoot 
A sccurage of trees is moving from East to 
West, and from South to North. Crawling cater- 
pillars threaten all 
of our fruit, shade 
and forest trees and 
vines this season. 
The caterpillars be- 
come “harmless” 
little moths, which 
lay eggs by the mil- 
lion. These in turn 
become caterpillars, 
which eat whole or- 
chards and avenues 
and groves of trees. 
Trees and vines 
breathe through 
their leaves. When 
leaves are eaten off, 
the tree is choked, 
and it dies, just as 
you would. The answer to tree murder by 
crawling creatures is: Make it impossible for 
them to crawl up to the leaves. They can’t pass 
a band of Tree Tanglefoot on the trunk. 
For property value and for defense, we need 
fruit and shade trees now as never before. But 
remember, you must band trees early, in Janu- 
ary and February in the South, in March and 
April in the North. Save your trees the approved 
way—with Tree Tanglefoot. 6-oz. size, 50c; 1 
Ib., 90c; 5 Ibs., $4.00, postpaid.

Roses that are permitted to become afflicted 
with insects and fungus diseases will lose their 
vitality and will not yield beautiful blooms. 
If your roses have the scientific protection 
of TRI-OGEN, neither insects nor the dreaded 
piece Spot or Mildew will harm or defoliate 
em. 
TRI-OGEN not only protects roses against 
all fungus diseases and insect pests, but it 
stimulates vigorous plant growth and assures 
healthy green foliage and luxuriant blooms. 
- «itis the most revolutionary discovery ever 
made in the history of rose culture. It is the 
most highly recommended product of its kind. 
TRI-OGEN PROTECTION IS COMPLETE. 
No other spray is required. Therefore, it has 
been found to be the most economical spray 
for roses. Moreover, it is a great labor saver.

kind and the sap “sucking.” The chewing kind attack and feed on the roots and foliage of 
plants, shrubs, etc.; the sucking kind attack the stalks and foliage. A different insecticide 
used to be necessary for each class. Now ‘'Green-Tox” kills both. It is a contact poison to 
sucking insects, and both contact and stomach poison to chewing insects; yet it is harmless 
to humans and domestic animals. '‘Green-Tox”’ not only kills insects, but likewise repels them. 
Foliage sprayed with ‘’Green-Tox”’ remains toxic to insects for many days and prevents 
reinfestation. No need to worry about insect damage when plants are sprayed with "'Green- 
Tox.” It takes the “guess” work out of spraying.
