2.4.1) Weed Killers 
(2-4-Dichlorophenoxyacetic Acid Weed Killer) 
Until now, means of weed control have been limited to cultivating and mowing, or to treatment with caustic chemicals 
that killed the foliage or poisoned the soil. These methods have been used because they were the only ones available, yet 
the total effect on the weed crop has been small. Today, 2,4-D Weed Killers exist as a new weapon of great effectiveness. 
It is economically practical in all respects. It kills the whole plant, is easy to apply and, perhaps most important of all, 
weeds are killed while grass continues to grow. Soil is not affected at concentrations recommended.

used according to directions.

This is the New Weed Killer

gest and practically every farm

Weedone is an oil liquid mix- 
able with water, and sprayed 
on the weed leaves. Tested 
more than three years, it is 
still the most effective 2, 4-D 
formula. Most weed - killers 
kill the top plant only, but 
Weedone goes into the leaves 
and down into the roots, killing 
the whole plant. Since Weedone 
kills not only weeds but many 
desirable plants, the spray must 
be kept from the leaves of the 
desirable plants, such as flow- 
ers and vegetables. Use One part Weedone in 100 
parts water, applying a gallon of spray to each 200 
square feet of weeds. 

Weedone kills most lawn weeds without killing 
the grass. It kills dandelion, broad plantain, buck- 
horn plantain, pennywort, heal-all, poison ivy, locust, 
poison oak, the mustard weeds, sumach, sassafras, 
choke cherry, honeysuckle, ragweed, bitter-weed, 
wild garlic, bind-weed, hoary cress, the thistles, and 
many others. It kills most legumes — clover, alfalfa, 
ete. Most grasses, including both lawn grasses, 
sugar cane, and the cereals, corn, wheat, oats, rice, 
are not killed by Weedone when used according to 
directions.
