Fight Bugs and Blight with 
PYROX is the powerful spray which kills 
chewing insects, prevents fungous diseases and 
stimulates foliage. It is a perfect mixture. 
Easy to prepare, sprays through the finest 
nozzle, stays on the hardest rain. 
Farmers have found it pays to give up 
spraying with home made Bordeaux. Instead 
they use Pyrox. It not only saves time and 
trouble but it coats the plant like paint, while 
home made Bordeaux leaves room between 
drops for the insects or disease to attack the 
plant. This is because Pyrox is made of 
perfect ingredients that go into complete 
suspension, will pass through the smallest 
nozzle. It will not clog and the pressure will 
force it out, not in large drops, but in a fine 
mist that completely covers the leaves. We 
recommend that you protect your farm crops 
with Pyrox. 
Pyrox wastes no time and labor. Simply mix with water according to directions and within five minutes 
vou are ready to spray. One pound of Pyrox makes 5 or 6 gallons of spray. Prices: 5 lbs., $1.70; 10 lbs., 
$2.90; 25 lbs'., $5.00; 100 lbs., $12.00; 300 lb. bbl., $30.00.
