Abstract
  • The life history of the fungus involved and the control for cherry leaf spot was studied ever a two-year period. It was found that the disease in Oregon is caused by the same fungus described in New York by Higgins in 1914 as Coccomyces hiemalis and which was more recently transferred to the genus Higginsia by Nannfeldt. The best control of the disease under Oregon conditions was obtained by the use of lime-sulfur. Fair control of the disease was obtained by the use of proprietary copper fungicides. Wettable sulfur sprays will produce excellent control under warm weather conditions, but they are not satisfactory during cool, wet weather. The recommended control, therefore, consists of lime-sulfur, two gallons per hundred of spray solution at the "petal fall" and "shuck fall" stages. If additional applications are made necessary due to wet weather, it is doubtless safer to use wettable sulfur (6 lbs. per 100 gals.) instead of lime-sulfur. Bordeaux-mixture gave good control but tends to dwarf the fruit when applied after the leaves are fairly well developed.
