• Comments:Apply when the majority of the population is in early instar stages.
  Where plum curculio is a later season problem, use one of the materials recommended at Petal fall.
  Actara: Do not apply when bees are in the orchard.
  Perm-Up, Silencer, Up-Cyde: Apply when most of the population is in early instar stages.
  Decis, Ripcord, Pounce, Matador, Perm-Up, Silencer, Up-Cyde: Resistance to these pyrethroid insecticides was recorded as widespread in the past. Resistance to these products may still be present.
  Agri-Mek: Apply no later than 21 days after petal fall. Apply with 10 L Superior Oil and a minimum of 1,000 L of water per ha. Apply when most mites are in the nymph stage. May cause russeting to d'Anjou and other sensitive varieties. Do not use oil within 14 days of a Captan or Maestro application.
  Pyramite, Nexter: There is little commercial experience with these products for psylla.
  Surround: See notes on Kaolin Clay (Surround WP).

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 7-9. Products Used on Pears.
