 This wash has not been advised in the Spraying Table 

 for the reason that number 4 is regarded as generally 

 more effective against the San Jose scale, in the east. 

 Wherever the spray to be used is directed against scale

 tion only, however. 



A fruit tree of average size, such as an apple, will 

 require from 3 to 7 gallons of any spray to wet it thor- 

 oughly. The object in spraying is to coat every leaf, 

 twig and branch — every part of the plant — with the 

 liquid. As soon as this is done, stop. Never attempt 

 to do the work with an ordinary hose nozzle, for a fine 

 misty spray is essential, and this of course cannot be 

 produced by anything but a special nozzle.
