Holly Cottony Scale: Systemic Insecticide

SW Florida hollies healthy but white powdery underside: cottony scale. Wipe cotton to reveal cigar-shaped bugs. Causes yellowing/leaf drop if untreated.

Bayer Advanced Tree and Shrub Insecticide soil drench per label.
Systemic kills in 1 week; protects 1 year.

Don't ignore; scale spreads and weakens plant over time.
