• Comments: Blossom blight is favoured by wet, warm (above 16°C) weather, especially when large numbers of mummies are present in the trees. Apply first spray when blossoms open, followed by two additional sprays during the bloom period if weather remains favourable for blight.
  Alternate among fungicide groups and do not use products from the same group in consecutive sprays. See Pest Resistance to Insecticides, Fungicides, Miticides, and Table 7-7. Products Used on Sweet Cherries.
  Nova, Funginex, Topas, Mission and Indar: Do not alternate within this group.
  Captan, Maestro or Bravo: Do not use within 14 days of an application of Superior Oil.
  Bravo: Do not apply after shuck to avoid fruit injury.
  Pristine and Lance: Do not alternate Pristine with Lance.
  

Precautions

Read the product label and follow all safety precautions.

Consult the product label for suggested water volumes. Otherwise, use enough water to ensure thorough spray coverage. Where the product rate is listed in amount per 1,000 L and if a water volume is not provided on the label, use enough water to wet the foliage to the near drip point.

Products are listed by fungicide and insecticide group. Use products from different groups to prevent pest resistance. For resistance management, refer to Pest Resistance to Insecticides, Fungicides, Miticides.

For preharvest interval, re-entry period, maximum number of applications and chemical group, see Table 7-7. Products Used on Sweet Cherries.
