Year-Round IPM Program Pages
This year-round IPM program covers the major pests of prune in California.
Postharvest (Fall)
- Why is this season important in an IPM program?
- Fall is when aphids migrate back into the orchard.
What should you be doing during this time?
Sample for mealy plum aphid and leaf curl plum aphid at 75% leaf fall to determine need for dormant sprays.
Consider zinc sulfate application to hasten leaf fall in order to disrupt aphid's life cycle.
Survey weeds after first rains and complete a late-fall weed survey form .
- Let resident vegetation grow between rows.
- Manage weeds in rows with pre- or postemergent herbicides or nonchemically in organic orchards.
Plan for next year.
