About Dormancy/Delayed-dormancy (leaf fall to bud swell)

- Mitigate pesticide effects on air and water quality.
What should you be doing during this time?
Apply fungicide treatments as needed according to Peach Pest Management Guidelines:
Manage orchard floor vegetation:
- Survey weeds and keep records (example weed survey form .
- Manage weeds with pre- or postemergent herbicides or nonchemically in organic orchards.
- If ground cover present, manage according to system needs. If frost is indicated, mow before bloom.
Make an oil treatment for scales and European red and brown mite eggs
- If you saw increasing damage from scales last year, take a dormant shoot sample to see if an insect growth regulator should be added to the oil treatment.
Treat peach twig borer and obliquebanded leafroller with environmentally sound material or delay treatment until bloom.
Other pests you may see:
