Disease history of Gremmeniella abietina in a Pinus sylvestris stand

Abstract
A new method has been developed for studying the history of Gremmeniella abietina infection in Scots pine (Pinus sylvestris) stands. The branch analysis method is based mainly on the occurrence of necrotic cankers and scars caused by G. abietina in annual shoots of branches. The supporting factors are the number of leader changes of branches and branch death model.
