Special Sprays: Early spring and/or fall

Raspberry crown borer (Special Sprays: Early spring and/or fall)

• Materials: Apply one of;
  • Diazinon 500 E @ 1.00 L/ 1,000 L water or Diazinon 50 W @ 1.00 kg/ 1,000 L water
  • Guthion 50 WSB @ 2.25 kg/ha or Sniper @ 2.25 kg/ha
• Comments: If more than 5% of the crowns are infested, apply this spray to lower portions of canes and to the crown area. Treat infested plantings at least two years in a row.
  Diazinon: Apply diazinon in 4,000–5,000 L of water per ha as a drench to crowns and base of plants. Apply in spring to control young larvae before they tunnel into crowns. Apply when new growth is about 10 cm above ground. Do not apply after first bloom.Guthion or Sniper: Apply in mid-September to mid October to control young larvae. Apply in 1,600 L of water per ha.

Phytophthora root rot (Special Sprays: Early spring and/or fall)

• Materials: Apply one of;
  • Ridomil Gold 480 SL @ 37 mL/ 100 m of row (apply in a drench spray to the soil surface in a 1 m band centered over the row. Use at least 2,500 L of water per ha)
  • Aliette WDG @ 5.50 kg/ha
• Comments: Ridomil: In new plantings, apply as a soil drench after planting and again in mid to late October (before the ground is frozen). In established plantings, apply Ridomil Gold in the fall only. Do not apply in spring to established plantings.
  Aliette: Aliette WDG is best as a preventive treatment. Maximum four applications per year: two in the spring and two in the fall.
  Spring application: Apply after bud break at 7 cm of new growth and again 3–4 weeks later. Do not apply within 60 days of harvest.
  Fall application: Apply when conditions favour disease development (high soil moisture and cool temperatures) and repeat if necessary 3–4 weeks later. The last application should be made at least 30 days before leaf drop.
  Precautions: Crop phytotoxicity is possible when Aliette is mixed with copper. Care should be taken if mixing Aliette with nitrogen-based foliar fertilizer. Incompatibility with some suspension concentrate formulations can occur.

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 family groups to help 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 5-14. Products Used on Raspberries.
