Dichlorophenoxyacetic Acid 
This wonder insecticide has’ received so much favorable promotion through its use by our Armed forces, that many people believe 
it is a “cure all” for all plant insects, diseases, household pests, live stock, and many other uses. According to the findings of the U. S. 
Dept. of Agriculture, and other investigators, this not so. D.D.T. has its good points and bad ones too. 
Use D.D.T. as effective plant spray or dust against Japanese 
Beetle, Colorado Potato Beetle, Pea Weevil, Cabbage Cater- 
pillars, Leaf Hoppers etc. 
For Live Stock and stable use against Horn Flies, Common 
For household use, Flies, Moths, Bed 
Bugs, Fleas, Ants, Roaches and other household pests. 
Flies, Lice and Fleas. 
D.D.T. will not combine with lime and make an effective insecticide. 
WE CAUTION ITS USE 
D.D.T. is not effective and does not control 
Scales, 
Mexican Bean Beetle, Red Spider, 
Mites, Turnip and Melon aphids and other 
plant lice. 
D.D.T. injures and retards Squash, Melons, 
Cucumbers and other cucurbits and corn. 
D.D.T. is a slow acting insecticide requiring from 15 minutes 
to 15 hours for the kill. D.D.T. is made up in many formulas, combined with other insecticides for more rapid results, such as py- 
rethrum and rotenone. D.D.T. can be mixed with Arsenate of Lead, Black Leaf 40, Sulphur and Basic Blue Stone. 
D.D.T. comes to us in many degrees of strength and carriers, as a dust or liquid. As a residual water dispersible spray, an oil 
carrier spray and a dust for dusting. Your Seed Store can recommend the kind to use for specific purposes. We recommend as follows. 
_ Wettable Powder contains 50% D.D.T. in- 
timately mixed with spreaders and an inert 
diluent to give excellent wetting and suspension 
in water. It has been developed for use in spraying 
operations to control such insects as codling moth, 
gypsy moth, tent caterpillar, leaf roller, Japanese 
beetle, Colorado potato beetle and thrips and 
also, flies and ticks on animals and in barns. 
MIXING AND SPRAYING 
Wettable Powder can be used with supple- 
mental insecticides such as nicotine sulfate, lead 
arsenate, oil emulsions, dinitro materials and 
others. It may also be used with fungicides such 
as Bordeaux, wettable sulfur, neutral coppers and 
organic materials. When using with Bordeaux, 
Wettable Powder should be added to the tank 
last as a thin paste. When oil is used add the 
Wettable Powder first and the oil last. 
Wettable Powder should not be used with 
hydrated lime or bentonite.

WHAT WEEDS DOES IT KILL 
WHAT IS 2-4-D 
2-4-D is the marvelous new weedkiller contain- 
ing 2.4 dichlorophenoxyacetic acid (DCP or 
2.4-D for short). When sprayed on to the leaves 
of certain weeds, it is absorbed by the plant and 
penetrates down into the roots, and thereby kills 
the plant throughout. For complete kill, all the 
foliage must be sprayed as there is little cross- 
movement within the stem. 2-4-D is effective 
only when the leaves are green and actively grow~ 
ing, for the chemical does not move through 
dormant or dead tissue. 
2-4-D usually takes a week to ten days before 
showing its first effect, and the plant takes two to 
four weeks to die. This slow action gives the 
chemical a chance to mave all through the plant. 
2-4-D kills most field weeds, most pasture and 
lawn weeds without killing lawn grasses or the 
cereal grasses: Corn, Wheat, Oats, Rice, or Bar- 
ley. 2-4-D is recommended for killing the follow- 
ing weeds, although it will kill mony others under 
favorable conditions: 
Poison Ivy Chickweed Burdock and 
Poison Oak Poverty Weed other Docks
