Japanese Magnolia Yellow Bark Spots + Sooty Mold: Scale Insects

Yellow plastic-like bark spots + sooty mold on leaves = scale insects. Scales suck sap, excrete honeydew → mold. Spreading fast.

Fix

Bayer Advanced soil drench. Roots carry imidacloprid to canopy. Scales die, mold stops. 1–2 weeks to top. Send photos for confirmation.
