DIRECTIONS FOR MIXING: Fill the spray tank one-half 

 or more full of water and pour the powdered material slowly

 add to the tank after the Soluble Sulphur Compound. 



DIRECTIONS FOR USE: Dormant Sprays— For early 

 spring or late fall spraying for the control of such troubles 

 as San Jose Scale, Oyster Shell Bark Louse. Peach Lecanium 

 Scale, Peach Leaf Curl, Aphis and Pear Psylla Eggs, etc., use

 open. Summer Sprays— For summer spraying when the trees 

 are in foliage, for fungus diseases such as Apple Scab, Bitter 

 Rot, Mildews, etc., one pound to 50 galons of water. Arsenate 

 of Lead may be used with this strength of material.

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.
