PEST AND DISEASE MANAGEMENT

If you choose to spray:o Use something recommended for the pest or

disease you are managing. o Read the label prior to use and follow all

instructions. o Verify that the spray is recommended for edible

fruits. o Some sprays are very toxic to bees and may

cause fruit drop if used within 30 days of bloom.

PEST AND DISEASE MANAGEMENT Cultural practices for good tree health.

o Consider a disease resistant variety.o Do not encourage vigorous new growth.o Warm, humid environments encourage bacteria.

Pruning opens air flow and reduces humidity.o Pick up dropped fruit and all leaves in the Fall.o Prune during freezing weather (Feb-March)o Mulch becomes dirt, so replace mulch as it

deteriorates.o Consider non-spray treatments, fruit bagging, red

sphere or Ladd traps.
