A new autumn sampling method accurately predicts apple scab risk, potentially saving growers time. Low-risk orchards can delay fungicide sprays without impacting harvest fruit scab levels.

Area of Science:

  • Plant Pathology
  • Agricultural Science
  • Entomology

Background:

  • Apple scab (Venturia inaequalis) is a major disease in New England apple orchards, necessitating fungicide applications.
  • Current management relies on action thresholds, but a simplified autumn sampling technique for predicting spring scab risk has been proposed but not field-tested.

Purpose of the Study:

  • To evaluate the field efficacy of a simplified, sequential autumn sampling technique for determining apple scab risk.
  • To compare the new technique's risk ratings with a traditional nonsequential procedure.
  • To assess the impact of a delayed-spray strategy in low-risk orchards.

Main Methods:

  • Orchards were assessed using the sequential sampling technique over three autumns (1999-2001).
  • Risk ratings were compared to a nonsequential procedure and analyzed via simulation.

  • Delayed-spray (post-third infection period or pink stage) vs. full-spray (green-tip) experiments were conducted in two orchards.

    • Main Results:

    • The sequential sampling technique yielded scab-risk ratings consistent with the nonsequential method, offering potential time savings.
    • Simulation analysis indicated risk ratings remained stable with variations in sampled trees or shoots.
    • Delayed-spraying in low-risk orchards did not significantly increase fruit scab at harvest compared to early spraying.

    Conclusions:

    • The sequential autumn sampling technique is a reliable and potentially time-saving tool for apple scab risk assessment.
    • Delayed-fungicide application strategies are viable for low-risk apple orchards, reducing unnecessary treatments.
