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. 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.

For information on identifying pests and monitoring apple orchards, refer to OMAFRA Publication 310, Integrated Pest Management for Apples.

Products are listed according to insecticide and fungicide group. Use products from different groups to prevent the 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 4-7. Products Used on Apples.
