European red mite (Prebloom)

• Materials: Use one of:
  • Superior 70 Oil @ 20 L/1,000 L water
• Comments: This is the preferred time to use oil for red mite control if overwintering populations are high. Red mite populations are more likely to be high if pyrethroid sprays were used the previous year for oriental fruit moth and tarnished plant bug control.

Oriental fruit moth (Prebloom)

• Materials: Use one of:
  • Isomate-M Rosso @ 500 dispensers/ha
  • Isomate-M100 @ 250 dispensers/ha
• Comments: Pheromone mating disruption products are not insecticides and will not control other pests that may be present. Initial OFM population must be low. Apply to square or rectangular orchard blocks at least 4 ha in size. Must be applied before moth flight begins. For more information on mating disruption refer to OMAFRA Factsheets Mating Disruption for Management of Insect Pests, Order No. 03-079 and Mating Disruption for Management of Oriental Fruit Moth in Stone and Pome Fruit, Order No. 04-029.
  Isomate-M 100: Make a second application 75-80 days after initial application.
  Isomate-M Rosso: Provides mating disruption for up to 120 days.
  If desired, use both an insecticide and mating disruption for managing first generation OFM (see Shuck split).

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.
