Aphids (Special spray)

• Materials: Use one of:
  • Movento 240 SC @ 365 mL/ha
  • Diazinon 50 W WSP @ 1 kg/1,000 L water
  • Clutch 50 WDG @ 210 g/ha
  • Beleaf 50 SG @ 120-160 g/ha
  • Thionex 50 W @ 3.25 kg/ha
• Comments: These may be added to a compatible fungicide after bloom. Thorough coverage and a calm, warm day are necessary for good aphid control.
  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. Must be tank-mixed with a spray adjuvant/additive having spreading and penetrating properties at a suggested rate of 0.2 % v/v. See label for further details. Do not tank-mix with sulphur.
  Diazinon: Registered for black cherry aphid only.
  Beleaf: Use higher rate for greater pest populations and/or dense foliage.
  

Peach tree borer and Lesser peach tree borer (Special spray)

• Materials: Use one of:
  • Thionex 50 W @ 1.5 kg / 1,000 L water
  • Sevin XLR @ 6.25 L/ha
• Comments: Apply first spray 7 days after first adult catch in pheromone traps. Spray up to three times if needed, at weekly intervals. Direct these sprays with a handgun to cover the trunk and scaffold limbs thoroughly. Check preharvest intervals, especially for the second and third sprays and do not apply if the fruit is to be harvested during this period. Sevin XLR is not registered for peachtree borer.

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.

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 grouped by fungicide and insecticide family. 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 7-6. Products Used on Sour Cherries.
