Black cherry aphid (Petal fall)

• Materials: Use one of:
  • Diazinon 50 W - see label
  • Zolone Flo @ 2.0 L/ha
  • Thionex 50 W @ 4.5 kg/ha
  • Movento 240 SC @ 365 mL/ha
• Comments: Diazinon, Thionex and Zolone: A temperature of at least 21°C, thorough coverage and a calm day are needed for effective aphid control. Usually 1-2 sprays are required.
  Movento: Most effective on young stages of aphids. Has slow activity; control may not be apparent for 2-3 weeks. Under high aphid pressure a second application may be necessary 2 weeks later. See the Movento label for additional details. Do not tank-mix with sulfur.

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.
