Oriental fruit moth (Prepick)

• Materials: Use one of:
  • Decis 5 EC @ 200 mL/ha
    
  • Ripcord 400 EC @ 175 mL/ha
    or Up-Cyde 2.5 EC @ 280 mL/ha
    
  • Pounce @ 275 mL/ha
    or Perm-Up @ 275 mL/ha
    or Ambush 500 EC @ 200-400 mL/ha
    
  • Silencer 120 EC @ 104 mL/ha
  • Altacor@ 285 g/ha
  • Delegate WG @ 420 g/ha
  • Assail @ 120-240 g/ha
• Comments: Spray each variety when first colour shows, 7-10 days before first harvest.
  If mating disruption is being used for OFM a prepick spray is not necessary unless local populations have historically been high or in cases where late season peaches are the only remaining fruit in an area.
  Decis: Maximum one application per year.
  Up-Cyde: Use in 550 L water/ha.
  Assail: For optimum activity, use the 240 g/ha rate. Apply in a minimum spray volume of 1,000 L/ha. Do not apply more than once every 12 days.
  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.
