Pyrox 



(Reg. U. S. Pat. Office) 



ONE BEST SPRAY FOR POTATOES. TOMATOES, 

 EGGPLANT, CUCUMBERS, ETC. 



If you spray your crops with Bowker's 

 Pyrox you will add to your profits. Pyrox 

 not only kills the destructive leaf-eating 

 bugs and worms and protects the vines 

 from blights, rust and fungous, but it has 

 a healthful, stimulating action on the 

 leaves, which are the lungs of the plant. 

 Even if no insects or fungus are to be 

 feared, it pays to spray your crops with 

 Pyrox, for its stimulating effect alone. 



Pyrox sticks to the foliage through 

 heavy rain, which gives you a great ad- 

 vantage. Most sprays wash off with every shower. The 

 Bowker Company has been manufacturing Pyrox for fifteen 

 years. Its use is no longer experimental.
