Green fruit

Anthracnose, Spur blight or Cane botrytis (Green fruit)

  • Materials: Tanos 50 DF @ 840g /ha
  • Comments: Ensure spray coverage of primocanes in the row. Keep rows narrow by mowing primocanes as they emerge at the row edges. Captan and Maestro used at this timing will also control spur blight.

Obliquebanded leafroller (Green fruit)

  • Materials: Apply one of;
    • Foray 48BA @ 1.4-2.8 L/ha
    • Bioprotec CAF @ 1.4-2.8 L/ha
    • Dipel 2X DF @ 550-1,125 g/ha
    • Delegate WG @ 200 g/ha
  • Comments: Leafrollers are not usually a problem in Ontario. Susceptible varieties include Chilliwack, Chilcotin, Tulameen and other varieties from the Pacific Northwest.
    Dipel, Foray and Bioprotec:
    Spray when larvae are very small and repeat at 3-7 day intervals, to a maximum of four applications. Acidify spray mix to below pH 7.0 and apply on cloudy days or evening. See Biopesticides and reduced risk products for insect control, and notes on Bacillus thuringiensis var. kurstaki.

Japanese beetle (Green fruit)

  • Materials: Sevin XLR @ 5.25 L/ha
  • Comments: Apply when adults appear and repeat as necessary at 7–10 day intervals. The preharvest interval is 11 days.

Rose chafers (Green fruit)

  • Materials: Malathion 25 W @ 4.50 kg/1,000 L water
  • Comments: Spray when adults are active.

Leafhoppers (Green fruit)

  • Materials:Apply one of;
    • Malathion 25 W @ 4.50 kg/1,000 L water
    • Admire 240 F @ 175mL/ha
  • Comments: Potato leafhopper can be a problem when nearby hay fields are mowed. New plantings are especially susceptible. Monitor for small green nymphs on lower leaf surface. Leafhoppers feed on primocane leaves and cause new growth to turn yellow and curl under. Spray when nymphs are present and symptoms are evident.
    Admire
    : Do not apply prebloom, during bloom, or when bees are actively foraging. Apply in 300 L water as a foliar spray. May provide suppression rather than control.

Raspberry cane borer or Red-necked cane borer (Green fruit).

  • Materials: Admire 240 F @ 467 mL/ha
  • Comments: Raspberry cane borer makes two rings of puncture marks around the top of the cane, causing the primocane to wilt. Spray to control beetles when damage is first observed. Red-necked cane borer attacks the lower primocane causing canes to break off 2-3 feet above the ground later in the season. If there is a history of this pest, spray when beetles are active
    Admire:
    Do not apply prebloom, during bloom, or when bees are actively foraging. Apply in 300 L water as a foliar spray. May provide suppression rather than control

White grubs (larvae of European chafer) (Green fruit)

  • Materials: Admire 240 F @ 1.2 L/ha
  • Comments: Control in young plantings where populations are high. Apply just prior to egg hatch (shortly after adults are active) to damp soil in the plant row and in the alleys, in 200 L water/ha. Move the product into the root zone with 5-10 mm irrigation within 24 hours of application. Use a maximum of 1 application per year.

Precautions

Always 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 according to insecticide and fungicide family groups. Use products from different groups to help prevent development of 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 5-14. Products Used on Raspberries.
