Abstract
Four virus diseases, rough bark of pears, vein yellow, pear ring mosaic and stony pit, decreased the yield during a 7 year period in the pear varieties ‘Beurré Hardy’, ‘Bosc’, ‘Clara Frijs’ and ‘Williams’. Rough bark disease stunted the affected trees considerably, and fruits from stony pit affected trees were of no value.
