Copper 53 W: For instructions on mixing copper
sprays, see Use of Copper Products on Fruit Crops on page 66. Don't
tank mix.

flower buds extend from crown
 Diseases
and Insects
- Strawberry clipper weevil
Materials and Amount/ha
- Furadan 480 F @ 1.10 L
- Ripcord 400 EC @ 175 mL
- Matador 120 EC @ 104 mL
Comments
Check edges of fields for clipped buds. Apply insecticide when first
injury is detected. Spray again if new injury is detected seven days
after the first spray.
Furadan: Do not use later than prebloom because
of its toxicity to pollinating and beneficial insects. Maximum one
application Furadan per season. Furadan can cause extensive burning
of sepals surrounding fruit on certain varieties (e.g. Annapolis,
and Cavendish).

Comments
Keep all flower parts protected with fungicide during bloom. Typically
2-3 sprays during bloom will give
good control. Shorten intervals to 3-5 days during wet weather. Use
Rovral, Ronilan, Elevate, Lance or Scala when disease pressure is
high. Choose fungicides from different chemical families and use them
in rotation. See Table 4-8. Fungicide/Bactericide Groupings Based
on Sites of Action, on page 59.
 Diseases
and Insects
Materials and Amount/ha
Comments
Make no more than two consecutive applications and then alternate
with fungicides from different families. See Table 4-8. Fungicide/Bactericide
Groupings Based on Sites of Action, on page 59.
Bloom is the best time to control this disease. Warm wet weather during
bloom favours the development of anthracnose.

Preharvest
 Diseases
and Insects
Materials and Amount/ha
Comments
Apply 50 kg/ha if population is very high. Apply when infestation
begins. Reapply as bait is consumed or at least every two weeks if
slugs and snails continue to be a problem.
 Diseases
and Insects
Materials and Amount/ha
- Pyramite @ 600 g
- Kelthane 50 W @ 2.00 kg
- Apollo SC @ 500 ml
Comments
Use high water volumes to ensure good coverage of the underside
of leaves. To discourage resistance, alternate products from year
to year and do not apply any product more than once each year.
Apollo: Apollo kills mite eggs and very young nymphs,
but not older nymphs and adults. Apply when monitoring indicates mites
are developing, mostly in the egg stage.

Comments
Begin applications on susceptible varieties (Annapolis,
Jewel, Veestar) when disease first appears on new growth or when conditions
(warm humid weather) favour development. Alternate with other fungicides.

Fall
Diseases
and Insects
Materials and Amount/ha
Comments
Bravo helps control botrytis by reducing disease inoculum. Apply
late October.
Diseases
and Insects
- Leaf blight
- Leaf scorch
- Leaf spot
Materials and Amount/ha
- Copper 53 W @ 3.80 kg
- Equal 65 WP @ 1.75 kg
- Supra Captan 80 WDG @ 4.25 kg
or Maestro 80 DF @ 4.25 kg
Comments
Spray susceptible varieties such as Bounty, Kent, Veestar,
Micmac, Tristar and Tribute. Alternate fungicides to reduce the development
of resistance.
Copper is labelled only for leaf spot.
Spray copper sprays alone. For instructions on mixing copper sprays
see Use of Copper Products on Fruit Crops, on page 66.
Equal may injure plants in cold weather.
Diseases and Insects
Materials and Amount/ha
- Ridomil Gold 480 EC @ 1.00 L
- Aliette WDG @ 5.60 kg
Comments
To reduce the chance of resistance, spray only where
red stele has been observed.
Ridomil: Do not apply later than October
31 or in the spring on established plants. Apply in sufficient water
(2500 L/ha) to ensure movement into the root zone.
Aliette: Make up to four applications
per season, two in spring and two in fall. Apply in spring when plants
start active growth. Apply at 30-60 day intervals. Do not apply within
30 days of harvest or after first bloom. Make postharvest applications
when soil conditions favour disease development (e.g., high soil moisture
and cool soil temperatures).
