Apples are more sensitive to it than pears and there are major differences in susceptibility between the apple varieties.
\nThe fungus spreads via spores in wet and humid weather. The fungus is a wound parasite that usually enters the tree in the fall through leaf scars and pruning wounds.
\nThe fungus can also be spread by the Woolly apple aphid<\/a> (Eriosoma lanigerum)<\/em>.
\nThe fungus can also infect apples and pears through the lenticels or through cracks around the stem. Infections during the blossoming season cause rotten spots on the noses; infections in (late) summer cause rotten spots around the stems (stem rot). The infection may already be visible on the tree in the autumn through rotten spots on the noses. If the infection only becomes visible after picking, it usually concerns rotten spots around the stem.
\nNeonectria neomacrospora<\/em> can cause canker spots on Nordmann spruce.<\/p>\n
