About Dormancy to Delayed-Dormancy
- Why is this crop stage important in an IPM program?
- Mitigate pesticide effects on air and water quality
What should you be doing during this time?
Count mummy nuts in orchard.
- If more than two nuts per tree remain, knock off and destroy mummy nuts by the initiation of bloom to reduce navel orangeworm and brown rot.
Manage orchard floor vegetation:
- After harvest, assess weeds present and identify those that were not controlled by a fall preemergence herbicide application.
- Keep records .
In January, consider applying postemergence herbicides in tree row strips alone or in combination with preemergence herbicides.
Take spur samples for scale and mite eggs mid-November to mid-January.
- Record results .
- Manage if needed according to the Pest Management Guidelines.
Examine trees for peach twig borer hibernacula in the crotches of one-year-old wood.
- Consult the Pest Management Guidelines to determine if treatments should be made during dormancy, bloom (Bacillus thuringiensis only), or in May.
- If scab infections are high, consider dormant or delayed-dormant treatments.
