Pest and disease management10

Pest and disease management

  • If you choose to spray:

    • Use something recommended for the pest or disease you are managing.

    • Read the label prior to use and follow all instructions.

    • Verify that the spray is recommended for edible fruits.

    • Some sprays are very toxic to bees and may cause fruit drop if used within 30 days of bloom.


Pest and disease management11

Pest and disease management

  • Cultural practices for good tree health.

    • Consider a disease resistant variety.

    • Do not encourage vigorous new growth.

    • Warm, humid environments encourage bacteria. Pruning opens air flow and reduces humidity.

    • Pick up dropped fruit and all leaves in the Fall.

    • Prune during freezing weather (Feb-March)

    • Mulch becomes dirt, so replace mulch as it deteriorates.

    • Consider non-spray treatments, fruit bagging, red sphere or Ladd traps.
