if necessary. If lime-sulfur solution is used, the strength 
advised is 1 to 50, with iron-sulfate one and one-fourth pounds 
to fifty gallons of the diluted solution. This mixture is used 
with safety, particularly with the addition of iron-sulfate, which 
reduces the burning qualities and increases adhesiveness. 
Sulfur dust, used at the rate of ninety parts finely ground sul- 
fur to ten parts powdered lead arsenate, has been found to be 
effective. 
In the nursery the same fungicides are recommended. The 
first application should be made when the cherry buds are 
about eight to twelve inches high. Subsequent applications 
depend on the weather. As a rule, five to seven applications 
at intervals of two weeks are sufficient. The earlier applica- 
tions often can be made advantageously at shorter intervals 
in order to keep the new growth covered.
