DISCUSSION OF TREATMENTS AND RESULTS. 
EARLY SPRING APPLICATION. 

Five per ct. Scalecide: Apples. On April 26, seven trees were 
sprayed with the five per ct. wash. The buds at this time were 
slightly swollen. The weather for the week following the appli- 
cation was clear, with slightly increasing temperature. The buds 
on the check trees opened rapidly during the first week of May 
but the treated trees were not as far advanced. On May 15, 45 
per ct. of the buds on the sprayed trees were not open while the 
checks were in full foilage. During the following two weeks the 
former were greatly improved in appearance, and by August 15 
the foliage on them seemed to be more abundant than that on the 
unsprayed trees. © 
Plums.—Three plum trees sprayed on April 26 were examined 
on May 15. There was no difference at this time between the 
checks and treated trees and these conditons continued the same 
throughout the summer. 
Pears.—Three pear trees treated before the buds opened showed 
severe retardation during the early part of May. A careful exam- 
ination at that time showed that about 75 per ct. of them were 
well open. Four weeks later these buds had fully developed, and 
the only trace of injury was the relatively less abundance of the 
leaves on the inner and lower spurs. 
Ten per ct. Scalecide: Apples.—For this application seven badly 
infested apple trees were selected. These were sprayed April 26. 
On May 10 about 15 per ct. of the buds had opened while others 
were somewhat retarded. As the season developed the effect of 
the oil became less noticeable, and by the first of June the foliage 
was heavy and of a good color. 
Peach.—A five year old peach tree, much infested, was selected 
for treatment. In making this treatment only one-half of the tree 
was sprayed while the remaining half was left as a check. As ~ 
the buds opened no difference could be detected between sprayed 
and unsprayed portions except that there was a slight retardation 
by the treatment. 
Two weeks later the entire tree was in full foliage and no dif- 
ference could be seen between the two portions. On August 1 the 
leaves on the checks were beginning to drop and by September
