The Effect of Pruning on the Mortality and Productivity of Red Raspberry Plants Infected with Botrytis and Didymella1

Abstract

Abstract Pruning of spur blight (Didymella applanata (Niessl.) infected or cane blight (Botrytis cinerea Pers. ex Fr.) lightly infected red raspberry plants increased mortality. Pruning of plants heavily infected with Botrytis had no effect on plant mortality but were less productive than those heavily infected with Didymella, while unpruned lightly infected with Botrytis were more productive than those lightly infected with Didymella.
