Branch, Stem and Collar Rot of Apple caused by Phytophthora Species of the ‘cactorum Group’

Abstract

BARK rot of apple trees, caused by Phytophthora cactorum (Leb. and Cohn) Schroeter, has been reported from most of the world's major apple-growing areas. Outbreaks of this soil-borne disease are often epidemic in character and may result in the complete bark-girdling and death of many trees.
