The distribution of Stecklenberg disease of Sour Cherry and peach ring spot disease of Sweet Cherry in orchards and nurseries

During a survey for Stecklenberg disease about 4, 000 sour cherry trees in the Altmark and Borde districts and in fruit-growing areas of Saxony and Thuringia were examined in 1955-57. In several districts up to 96% of the orchard trees were infected while in nurseries 5% of the mazzard seedlings and young sweet cherry trees were infected by Stecklenberg and peach ring spot virus, respectively. Symptoms of Stecklenberg on sour cherry are not detectable in the first 6 yr.
