Well I think I found the problem that is killing the Magnolia I have in my back yard but I am not sure what those bugs are. I have lived in this house my hole life and have notice a problem with branches rotting at least 10 years ago but was never sure what the problem was till now. It is a large tree and has many new branches growing on it but I am not sure if I am going to be able to save it at this stage. The underside of the leaves are covered with these things and they are everywhere. What are they and what can I do about them?

These are scale insects, sap feeders that can be difficult to control because of their protective covering. See http://tinyurl.com/23snvnq for a fact sheet that includes control recommendations.

Thank You. This is from the link you gave............

� Systemic insecticides
Imidacloprid (Bayer Advanced Garden Tree & Shrub Insect Control Concentrate) is applied as a drench around the root zone of infested plants. This water soluble insecticide is taken up by the roots and transported throughout the plant where it is ingested by sap feeding insects. This provides a means of scale control without reliance on sprays. However, it may need to be applied several weeks before crawlers are active for best results

Any body try this stuff?
