CHAPTER V 
Insects, Diseases, AND SPRAYING 
SEVERAL years ago spraying was not 
considered necessary for the production 
of a large crop of good quality, but with the 
increase in the acreage and the multiplication 
of varieties, the insects and diseases have 
become so troublesome that in very many 
places where strawberries are grown it is 
highly important that spraying and other 
advanced methods should be carried on 
in order to grow this crop successfully. 
With the demand for knowledge concerning 
these insects and diseases among the growers, 
more and closer study of this valuable fruit 
has been forced on experimenters and 
students throughout the country, as well as 
upon the manufacturers of spraying machines 
who try somewhat to cater to the needs of 
the growers and students. There is, however, 
room for improvement along these lines.
