Hi, I wish to control scale on my Bay Tree with Malathion. What is the
mixture rate to use. Do I need to mix it with while oil for it to be
effective.


A dormant oil spray, mixed at the 1/2 strength "summer oil spray" rate
would be more effective, but iirc you should not use oil spray when the
temperature is about 90 F. degrees. There will be directions on the label.
