Is there a cure for sudden oak death?

While there is no cure for Sudden Oak Death or other P. ramorum-associated diseases, there are preventive measures that may protect plants. The publication “Protecting Trees from Sudden Oak Death Before Infection” provides helpful treatment information for areas not currently infested but at risk.

How do you kill red oak borer?

Spray the bark of the trunk, branches over 4 inches in diameter and foliage with a cyfluthrin, permethrin, bifenthrin or carbaryl insecticide. Make one spray application in the spring and another in midsummer. Use a tree sprayer set for the height of the tree based on the manufacturer’s label instructions.
