Magnolia Tree mealy bugs
I'm wondering what the best treatment is for mealybugs on my magnolia tree. I'm also wondering if the U of M's extension services has anybody who can come out to treat our tree. Thank you! -Dan Christensen

Another option would be to use a chemical insecticide. Imidacloprid is a systemic insecticide applied as a soil drench. This insecticide is taken up by the roots and transported throughout the plant where it is ingested by the scale insect. Application can be done in late April through early May or August through September.
Thank you for contacting Extension.
