BARTELDES WEED KILLER 
70% 2, 4-D ACID 
This is the product that revolutionizes weed kill- 
ing. Instead of burning the vegetation back, as 
former weed killers did, a small amount of 2, 4-D, 
when sprayed on weeds, will penetrate the entire 
plant structure, causing the plant cells to disin- 
tegrate. And it doesn’t injure or discolor lawn 
grasses permanently, injure the soil, is not poi- 
sonous, doesn’t burn the skin or stain clothing. 
It is now possible to kill most lawn weeds includ- 
ing dandelions, plantain, chickweed, yellow tre- 
foil, dock, purslane, cress, peppergrass, speed- 
well, knotweed, mustard, etc., with little expense 
BARTELDES 2, 4-D 
Aeroplane dusting for insect control has been gaining in 
popularity each year. Now we have an aeroplane dust 
for controlling bindweed and other noxious weeds. Any 
weed or plant that can be killed with the spray method 
can be killed by the dust method. 
Dusting should be done early in the morning when dew 
is on the leaves of the plants to be killed. The dust 
will also settle better at this time of the day because 
of no wind or rising soil heat radiation. 
In June, 1946, we supplied the 2, 4-D dust for the experi- 
ment on the John Metzgar farm at Broomfield, Colorado. 
Thirty acres of barley, badly infested with bindweed, 
were dusted by plane. ‘'his field also had a stand of 
alfalfa. The results were excellent. The barley was not 
affected and was easily harvested. The bindweed was 
soon withered and disappeared—no bindweed reappeared 
or trouble. Simply mix 14 ounce of Barteldes 
Weed Killer (powder) to a gallon of water and 
spray to every 300 square feet of lawn area. 
Bindweed, Canada thistle, perennial peppergrass, 
Russian knapweed, poverty weeds can now be 
controlled with as little as 3 lbs. to 200 gallons of 
water to the acre. It doesn’t injure cereals. You 
can raise a crop and spray or dust the weeds at 
the same time.

Thirty to thirty-three pounds of Barteldes 2, 4-D Aero- 
plane Dust should be used per acre. 
Prices: $18.00 per 100 Ibs.; 500-Ib. lots, $17.50; ton lots 
at $17.00 per 100 Ibs. Plane operators customarily charge 
5c per pound for applying. 
We believe you will find this method more economical 
than spraying as the handling and transporting hundreds 
of gallons of water is eliminated. There is no knocking 
down of grain or other crop destruction as when tractors 
and sprayers are used. Time is saved. 
CAUTION: Do not allow dust to drift on crops suscepti- 
ble to 2, 4-D.
