NON-POISONOUS LIQUID INSECTICIDE 
KILLS LEAF EATING AND SUCKING INSECTS 
Harmless To Humans And Pets—Non-Injurious To Plants And Blossoms 
There are two distinct classes of insects, surface and subsurface, the chewing “eating” 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. 
Prices: Ounce size, 35c; 6 oz., $1.00; 16 oz., $2.00; 32 oz., $3.50. If wanted by parcel post, please add postage.

EMULSIFYING S 
PROTECT YOUR TREES FROM THESE PESTS 
The peach tree borer (Sanninoidea Exitiosa Say) feeds actively in the fall, spring and summer 
months, and lies dormant during the winter. It attacks the soft inner layer of bark usually just 
beneath the ground and sometimes along the larger roots. The presence of these pests is indicated 
by masses of gum mixed with brown frass or “sawdust” exuding from the injured trunk. The borers 
become full grown from the middle of June to the first of September, and then spin silk cocoons 
which hatch into clear winged moths. During the six days these- moths are alive they lay from 200 
to 800 eggs—which shows what a menace they will become if not properly checked. 
SANTOCHLOR WILL KILL THEM 
The popular and modern way to rid your orchard of these worms or borers is to apply Paradichloro- 
benzene around the base of all trees. Monsanto’s trade name for this product is SANTOCHLOR, 
which is unadulterated Paradichlorobenzene, practically 100 per cent pure. 
It is a white crystalline substance that changes to a gas heavier than 
a’r, and penetrates the burrows of the borers. It is fatal to insects, but 
will not harm man or domestic animals unless taken internally. 
The SANTOCHLOR method has rapidly replaced the old-fashioned 
“worming” process for control of borers. Digging the worms out with 
a knife may be as injurious to the tree as the worm. In two “wormings” 
with a knife it is seldom possible to get more than 90% of the pests. 
With SANTOCHLOR, however, it is a common occurrence to kill from 
95% to 100'% with one application, and it is also a great deal less bother. 
Tree Borer 
A RING OF DEATH 
SANTOCHLOR is applied to the cleaned surface of the ground around the base of the tree, after 
any masses of gum have been removed from the tree trunk. The trunk should be completely en¬ 
circled by one ounce of the white crystals, care being taken to leave two inches space between the 
trunk and the inside of the white band. This mound is then covered with fine earth and packed 
down firmly. One treatment per year, in the fall preferably, will usually be sufficient protection. 
Complete directions, together with the best times to apply for different States, appears on every 
package. 
COST IS LOW—ORDER NOW 
A five-pound package of SANTOCHLOR is sufficient for 80 trees. An experienced man should be 
able to treat 15 to 20 trees in an hour. 
Don’t postpone the use of SANTOCHLOR. Order a handy carton and see for yourself what the 
product will do for your trees. 
Pound cans, 75c; 5 lbs., $2.75, postpaid. If wanted in larger quantities, write for prices.
