TO CONTROL CHEWING AND SUCKING INSECTS 
Bowker’s Powdered Arsenate 
of Lead 
Can be used either as a spray or as a

l>etter, but to kill better. Mixes easily, 
stays well in suspension, with no trouble 
from clogged nozzles. 
Also used extensively for soil-treatment 
of golf greens and lawns to control white 
grubs and beetles that infest the sod and 
eat the roots of grass. Use 4 to 8 pounds 
for each 1,000 square feet of surface, mixed 
with top-soil, loam, or fine sand. Use 4 
pounds of Arsenate to about 1 bushel of soil.
