WHAT AILS YOUR PLANTS? 



The Insects and Diseases That May Attack 



Your Vegetables and Fruits, and How 



TO Vanquish Them — How to Make 



Spray Mixtures 



Many books and free bulletins from various 

 sources tell how to make Bordeaux mixture, ar- 

 senate of lead solution, etc., but all on the basis 

 of 50 gallons. This is, of course, much too large 

 a scale for most backyard gardens, and it is 

 more or less inconvenient mathematically to reduce 

 all the amounts proportionately. The regular, 

 standard formulas are here given in the quan- 

 tities that you and I are apt to need in our 

 home garden. The amounts are expressed through- 

 out in terms of every household — the teaspoon, 

 the tablespoon and the Mason jar. You will 

 need nothing unusual to measure with or to mix 

 with. 



If possible, in measuring and mixing your spray 

 materials use old utensils and keep them apart for 

 this use. Put them in a safe place. You may use 

 good silver and glassware, and afterward wash it 

 clean, but wash it very thoroughly, in hot water.
