Red Stele (When new growth appears)

• Materials: Aliette WDG @ 5.60 kg
• Comments: This disease is sporadic and favoured by wet or compacted soil, and susceptible varieties (Table 5-23. Strawberry Variety Disease Ratings). To reduce the chance of resistance, spray only where red stele has been observed or a high risk situation occurs.
  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.

Botrytis grey mould (When new growth appears)

• Materials: Bravo 500 @ 3.50 L
• Comments: Bravo: Reduces disease inoculum and prevents infection of dying leaves. Repeat application in ten days.

Aphids (When new growth appears)

• Materials: Admire 240 F @ 850 mL-1.2 L/ha
• Comments: Apply in a high volume of water to the soil (e.g. 2,000 L water/ha). Do not apply in transplant water or through drip irrigation. Very toxic to bees. Do not apply when bloom is present.

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.

Products are listed according to insecticide and fungicide family groups. Use products from different groups to help prevent pest resistance. For resistance management refer to Pest Resistance to Insecticides, Fungicides, Miticides.

For information on strawberry pest identification, monitoring and thresholds, see ONTARIO CropIPM: Integrated Pest Management Training, available at www.ontario.ca/cropIPM or as OMAFRA Publication AF141 in CD format.
