If You Can Add Ten Days 
of Growth, Your Crop will 
Increase One-Third 
How To Do It: Spraying for bugs alone will not 
do it. Paris Green, Arsenate of Lead—any poison 
may indeed save your crop from bugs, but it won’t 
increase it nor add anything to its quality value. Pyrox does 
both and it kills the bugs. Paris Green, as is well known, often 
stunts the vines and shortens the crop. 
OUGS look bad to you but the are not 
your worst enemy. As a matter of fact, 
blig^ht is more destructive. The spores are so 
tiny they cannot be seen with the naked eye, 
but actually they rob you of more potatoes 
than bugs do. Ask any agricultural authority. 
'T'^HE New York Experiment Station says: 
^ ‘‘It does not pay to spray for bugs alone.’* 
Ten years’ experience at that Station spraying 
against blight shows an average yearly gain 
per acre of 97^^2 bushels per acre. 19 years in 
Vermont gives 109 bu. per acre average gain 
per year. Spray against blight. It Pays.

P YROX protects the crop against blight and at the 
same time kills the potato bug. It keeps the fol¬ 
iage healthy and green throughout the growing 
season; gives it greater vigor and enables the plant to 
produce to its limit. Every potato grower knows that 
the last ten days is the period when the tubers are in¬ 
creasing in size. Pyrox is maturity insurance of the 
very best sort. It gives the little potatoes a chance to 
grow up into big ones. 
Pyrox is a smooth, creamy paste, all ready to use by 
mixing with cold water. Just measure it out, and mix 
it with water for your spray solution. This saves labor 
at the busiest time of year when labor is hard to get. 
In a letter to a friend, the Editor of the “Fruit Belt” 
says: “I have made up many thousands of barrels of 
spray mixtures on the farm, and I can say to you I have 
mixed my last barrel. There’s as much difference be¬ 
tween Pyrox and home-made sprays as between the 
old stage coach and the modern railroad train. The 
best growers are using it.” ,
