Abstract
SUMMARY The infection of the apple stem by the canker fungus through the leaf scare is described. The fungus appears to enter through small cracks which appear in the leaf scar tissues, in the autumn immediately after defoliation and in the spring when the buds are swelling. The possibility of preventing this infection by disinfecting the leaf scare by fungicides is discussed and results of preliminary trials recorded.
