Control. — The control of this pest has been somewhat complicated 

 and nnsatisfaetory, although at the present time considerable or com- 

 plete success attends the efforts of careful work. Without doubt the 

 best control measure is the application of a carbolic acid emulsion 

 spray, which should be applied plentifully, from ten to fifteen gallons 

 to an average size tree, and under a pressure of two hundred pounds.

"We have found that two angle "Bean Jumbo" nozzles on a "Y" to 

 each rod give best results. Large-holded discs should be used in the 

 nozzles to insure a coarse driving spray. 



If the mealy bug is present in great numbers it may be necessary 

 to make two, three or even four applications a week or so apart. 



During the winter, when there are large numbers of egg-masses, or 

 in the spring when the young are hatching, is the best time for apply- 

 ing the sprays.
