Spray thoroughly, drenehing the trees from the tops to the 

 ground. Make a special effort to thoroughly wet the under sides 

 of every branch. 



While in the above experiments one application of the emulsion 

 Avas sufficient to indicate the effects of the spray, fruit growers have 

 found that at least two applications, and in some cases three, are 

 necessaiy to insure thoroughness. 



For winter treatment do not use the emulsion weaker than one 

 part of the emulsion to four or six parts of water. 



If there are still some live scales left on the trees in the spring, 

 • do not spray until the young scales begin to come forth, about July 

 1st, then spray at once with kerosene emulsion diluted with not 

 more than nine parts of water. 



Do not try to use a power sprayer. A hand force pump attached 

 to a tank or barrel, so arranged as to be easily carted through the 

 orchard, will be found more satisfactory. Use a nozzel that will 

 apply the mixture in a very fine spray, such as that produced by the 

 Vermorel or McGowen.
