Woolly elm aphid, Woolly apple aphid (After Harvest)

• Materials: Use one of:
  • Orthene 75 % SP @ 1.7 g/plant (See label)
  • Admire 240 F @ 0.125mL/plant
• Comments: These aphids feed on plant roots and reduce plant vigour. After harvest dig up suspect bushes and examine the root systems for waxy white aphid colonies. Young plantings are especially susceptible. Make one application in mid-July to mid-August, after harvest is complete.
  Orthene: Application is by soil injection. Mix 0.85 g/L of water. Apply 2 L of this solution per plant. Inject in 3-5 injection points about 12 inches deep. See product label for special application instructions.
  Admire 240 F: Apply in 200 L water/ha to the soil at the base of each plant, followed by sufficient water to move the product to the root zone. Admire provides suppression rather than control of woolly aphids. See Table 2-6. Efficacy Ratings for Pesticides.

Precautions

Read the product label and follow all safety precautions.
Always 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 preharvest interval, re-entry period, maximum number of applications and chemical group, see Table 5-17. Products Used on Saskatoon Berries.
