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 710 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.
