Cherry fruit fly (Third cover)

• Materials: Use one of:
  • GF-120 NF @ 1.5 L/ha
    or Entrust 80 W @ 109 g/ha
  • Admire 240 @ 233 mL/ha
  • Assail 70 WP @ 240 g/ha
  • Imidan 50 WP @ 3.75 kg/ha
  • Diazinon 50 W - see label
  • Zolone Flo @ 2.0 L/ha
  • Sevin XLR @ 6.25 Lha
• Comments: GF-120 NF: Spray as soon as monitoring traps indicate flies are present or 2-3 weeks before ripening. GF-120 is a bait formulation that requires large droplet size (4-6 mm): specialized application equipment may be needed. GF-120 will lose effectiveness if exposed to rain or overhead irrigation.
  Admire: Monitor for cherry fruit fly and apply as a foliar spray within 6 days of first fly emergence. Thorough coverage is necessary for optimal control. Allow at least 10 days between applications.
  Assail 70 WP: Provides suppression of cherry fruit fly. See Table 2-6. Efficacy Ratings for Pesticides.
  Sevin, Imidan, Zolone and Diazinon: Spray sour cherries about the time Montmorency is turning pink.
  Sevin: Provides 5-7 days protection.
  Zolone: Maximum three applications per season.
  

Brown rot (Third cover)

• Use one of the fungicides recommended at Shuck split.
  Topas, Mission: No more than two applications in the three weeks prior to harvest.
  

Leaf spot (Third cover)

• Use one of the fungicides listed under Petal fall with the exception of Ferbam and Bravo.

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 grouped by fungicide and insecticide family. 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 7-6. Products Used on Sour Cherries.
