  • SUMMARY Laboratory experiments using sterilized apple-leaf discs showed that treatment of leaves with urea during the early stages of perithecial initiation induced a high nitrogen content of the leaves, which prevented further development of perithecia although mycelial growth was unaffected. Treatments applied at a later stage of fungal development inhibited both perithecial and mycelial growth. Some of the bacteria isolated from urea-treated leaves in the field restricted… CONTINUE READING
