Obliquebanded leafroller (Special spray)

• Materials: Use one of :
  • Dipel 2X DF @ 1.12 kg/ha
    or Bioprotec CAF @ 4.0 L/ha
  • Success 480 SC @ 182 mL/ha
    or Entrust 80 W @ 109 g/ha
  • Altacor @ 285 g/ha
• Comments: Routine monitoring is necessary to determine if obliquebanded leafrollers are causing damage in sweet cherries.
  Altacor and Delegate: For OBLR summer generation, apply at 240-280 degree days C (base 6.1 C) after biofix (first sustained moth catch).
  Altacor: Do not exceed 645 g/ha per year.
  For resistance management, if more than one spray is required for this generation, use a product from the same chemical family. For subsequent generations, rotate to another chemical group.
  Dipel, Bioprotec: See Biopesticides and reduced risk products for insect control.
  

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.
