SPRAYING 221 



Outdoor Spraying of Sweet Peas. 

 Under our present conditions, it is difficult 

 to raise a crop of sweet peas outdoors with- 

 out its becoming infested with most of the 

 pests enumerated in this book. Spraying 

 therefore becomes a necessity. However, 

 the grower cannot afford to spray for each 

 pest separately. A combination of spray 

 mixtures becomes imperative so that one 

 application may reach at the root of many 

 evils. Red spider, the green aphid, the 

 chewing insects, as well as the fungous 

 diseases of stems and leaves, may be con- 

 trolled by a combination of the following 

 materials in the following given propor- 

 tions: 



1. Make the regular 5-5-50 Bordeaux 

 formula. 



2. If the green aphid is present add to 

 every lOO gallons of the Bordeaux three- 

 fourths of a pint of "Black leaf 40."
