Read the label and follow all safety precautions.
Consult the product label for suggested water volumes. Otherwise, use enought water to ensure thorough spray coverage. Where the product rate is listed in amount/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.
For resistance management, refer to Pest Resistance to Insecticides, Fungicides, Miticides, on page 54.
For preharvest interval, re-entry period, maximum number of applications and chemical group, see Table 10-10. Products Used on Sour Cherries, on page 229.

Prebloom

Diseases and Insects

  • European red mite

Materials and Amount/ha

  • Superior 70 Oil @ 20 L/ 1,000 L water

Comments

Only needed in sour cherry orchards with a heavy mite population. Spray as buds are breaking. Mature trees require water volumes of approximately 3,000 L/ha for thorough coverage.
Captan, Maestro or Bravo: Do not apply within 14 days of oil.

Bloom

Do not apply insecticides while cherry trees are in bloom. See bee poisoning on page 79.

Diseases and Insects

  • Brown rot (stem rot and blossom blight stages)

Materials and Amount/ha

  • Topas 250 E @ 500 mL
  • Nova 40 W @ 340 g
  • Rovral @ 1.50 kg
  • Bravo 500 @ 7.00 L
  • Supra Captan 80 WDG @ 4.50 kg
    or Maestro 80 DF @ 4.50 kg
  • Funginex 190 EC @ 2.50 L
  • Kumulus DF @ 22.50 kg
  • Elevate 50 WDG @ 1.70 kg
  • Lance WDG @ 370 g
  • Indar 75 WSP @ 140 g
  • Mission 418 EC @ 300 mL

Comments

Spray just before blooms open if weather conditions are expected to be wet and warm (above 16oC) during bloom. Sour cherries are less susceptible to brown rot than sweet cherries. One application during bloom should be sufficient, unless frequent wet periods occur and brown rot pressure is high.
Captan, Maestro or Bravo: Do not use within 14 days of an oil application.
To avoid resistance do not apply Topas, Rovral, Elevate, Indar or Lance more than two times for each product per season. Alternate between fungicide families and do not use the same product in consecutive sprays. See Pest Resistance to Insecticides, Fungicides, Miticides, on page 54.
Nova and Topas are absorbed by flower parts, making these materials more rainfast than other protectant fungicides.
Topas also suppresses black knot.

Table 10-10. Products Used on Sour Cherries

Use this table as a guide, but refer to product label for specific information.

The preharvest interval is the number of days between the last spray and first harvest.

The re-entry period is the minimum interval that must be observed between applying the pesticide and working in the treated crop without protective equipment. If no re-entry period is stated on the label, assume that the spray solution must be dry before re-entry can occur.

The maximum number of applications is the labelled maximum number for the growing season, and may be higher than what is recommended for resistance management or for preserving beneficial insects.
