Regional Notes

Golden apples develop brown netted russet patches, especially after cool, wet weather during bloom. Multiple causes include frost, viruses, spray materials, or powdery mildew. Late-maturing Golden strains like Criterion and Smoothee russet less; select these if russeting is chronic. Manage powdery mildew to reduce associated symptoms.

Grow cultivars less susceptible to russeting. The late-maturing 'Golden Delicious' strains, 'Criterion', and 'Hawaii' normally do not russet in mild, dry spring conditions.

Cultural Controls

  • Grow cultivars less susceptible to russeting.
  • The late-maturing 'Golden Delicious' strains, 'Criterion', and 'Hawaii' normally do not russet in the Willamette Valley. 'Smoothee' (a 'Golden Delicious' strain) and most of the red apples have little russeting.
  • Manage trees for powdery mildew.
  • Check for uneven spray distribution or worn nozzles.
  • Use only virus-indexed scion wood.
