Leaf curl (Dormant)

• Materials: Use one of:
  • Ferbam 76 WDG - see label
  • Bravo 500 @ 7.0 L/ha
  • Copper Spray @ 2.0 kg/1,000 L
    Guardsman Copper Oxychloride @ 2.0 kg/1,000 L
• Comments:A delay in application may result in poor control of leaf curl.
  Ferbam: If mixing with oil, follow mixing directions on the Superior 70 Oil label carefully or poor leaf curl control will result.
  Bravo: Do not apply within 10 days of an oil application because it will burn flower and leaf tissue.
  
  

San Jose scale (Dormant)

• Materials: Use one of:
  • Superior 70 Oil @ 20 L/1,000 L water
• Comments: Apply oil routinely every third year. If scale is a serious or continuing problem, apply oil for at least two consecutive years.

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.
