Using vented orchard covers for protecting cherries

These resources detail the process and findings from an applied research project that studied using vented orchard covers to protect cherries from rain splitting and hail damage.

The three-year study looked at:

  • Cost-effectiveness of vented covers
  • Fruit sugars, firmness and size
  • Rain and hail damage between covered versus uncovered fruit

Further research/data is needed before making recommendations to industry, but project findings included:

  • Cracked fruit was reduced when under covers
  • Covers increased humidity by 20-30%, reducing irrigation requirements by 30% compared to fields in close proximity
  • Covers mitigated heat street of trees, under extreme heat situations
  • No instances of powdery mildew under covers
  • Covered crops had similar levels of sugars and firmness to uncovered crops
  • Covers did not guarantee protection from rain and hail but were a significant improvement
