European red mite (Prebloom)

• Materials: Use one of:
  • Superior 70 Oil @ 20 L/ 1,000 L water
  • Purespray Green Spray Oil 13E @ 20 L/1,000 L water

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.

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.
