Oriental fruit moth (Second generation)

• Materials: Use one of:
  • Altacor @ 285 g/ha
  • Delegate WG @ 420 g/ha
  • Assail 70 WP @ 120-240 g/ha
  • Ripcord 400 EC @ 175 mL/ha
    or Up-Cyde 2.5 EC @ 280 mL/ha
    
  • Matador 120 EC @ 104 mL/ha

    or Perm-Up @ 275 mL/ha
    
  • Decis 5 EC @ 200 mL/ha
    
• Comments: Spray all varieties. This generation may require two insecticide sprays applied about 14 days apart.
  If mating disruption for OFM is being used a pesticide application is not required for second generation OFM.
  Altacor, Delegate: Apply at first egg hatch, 50-100 degree days C (base 7.2°C) after biofix (first sustained moth catch). Monitor populations and reapply 10-14 days later if required. Check the harvest dates of early varieties and do not spray within the preharvest interval.
  Altacor: Do not exceed 645 g/ha per year.
  Assail: For optimum activity, use the 240 g/ha rate. Apply in a minimum spray volume of 1000 L/ha. Do not apply more than once every 12 days. Will also control plum curculio.
  Up-Cyde: Use in 550 L water/ha.
  Decis: Maximum one application per year.
  For resistance management, if more than one spray is required for this generation, use a product from the same chemical group. For subsequent generations rotate to another chemical group.

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 7-8. Products Used on Peaches.
