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.

Products are listed by fungicide and insecticide group. Use products from different groups to 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 7-8. Products Used on Peaches.
