D ON’T let insect pests and plant diseases rob you 
of the biggest part of your crop profits. Proper 
spraying of potatoes, other vegetables and small 
fruits with Pyrox represents so little of the total cost 
of crop production—and adds so definitely to the 
returns—that no one can question its value. 
And Pyrox is an economy in the spraying itself: It 
saves the time-and-labor cost, as well as the muss and 
uncertainty, of home-made sprays. Pyrox is ready to 
use. It is a smooth, finely milled paste—a powerful 
FUNGICIDE extra high in copper content , perfectly 
blended with a deadly POISON. 
In addition to killing leaf-eating insects and repel¬ 
ling flea beetles and leaf hoppers, Pyrox controls rusts 
and blights. Also—Pyrox invigorates the plant, 
lengthens the growing period, increases yield and 
improves quality. Ideal for home gardens! 
Pyrox is uniform. It is dependable. Milled like 
fine paint, it mixes thoroughly. It sprays easily with¬ 
out clogging smallest nozzles. Mist-like, it goes far; 
covers foliage completely; and sticks like paint. 
Pyrox represents 25 years’ experience. The leading 
spray with most dealers. Jars, cans, drums, barrels.
