Weed Killers 
WEED KILLER A-510. 
(Formerly Listed as No. 24) 
The Dow Chemical Company’s new selective herbicide 
designated as A-510 is a water-soluble powder, 70 per cent 
of which is 2.4-dichlorophenoxyacetic acid. This weed- 
killer, when dissolved in water, forms an effective herbi- 
cide useful in controlling most broadleafed types of weeds 
but not grasses. 
ADVANTAGES OF A-510 
1. Effective at low concentrations. 
2. Noncorrosive to spray equipment, 
8. Is selective in action, controlling broadleafed types 
but not grasses. 
4. Readily soluble in water, 
penetrants. 
5. Relatively nonpoisonous to animals when applied as 
directed to foliage. 
6. Does not sterilize the soil. 
7. Action is permanent. Roots, 
stems, are killed 
8, Nonexplosive. 
9, Nonirritating to the skin. 
10. Will not stain or injure clothing. 
11. HEconomical 
requiring no activators or 
as well as foliage and 
TENTATIVE DOSAGE RECOMMENDATION 
Dissolve 1% pounds of A-510 in 100 gallons of water and 
apply the diluted spray material to foliage at the rate of 
from 125 to 200 gallons per acre, depending upon foliage 
density. Thi sdilution gives 1050 ppm. The efficiency of 
this material depends upon thorough coverage of the weed. 
growth. A-510 may be applied with any type of spraying 
or sprinkling equipment. Where dense foliage occurs, it 
is advisable to apply this material under pressure, pref- 
erably between 75 and 250 pounds per square inch. Higher 
pressures tend to cause a matting of the vegtation, thereby 
preventing thorough coverage. It is further recommended 
that A-510 be applied while th etemperatures are fairly 
warm. Barly spring and late fall applications require two 
to three weeks for maximum effects.
