Rhododendron Scale Insects: Identification and Treatment Options

Rhododendron has 1cm white lumps with brown tips on leaf backs and stalks; plant healthy, flowering. Photo shows slightly out-of-focus white objects.

Identification

Likely scale insects—suck plant juices, flick off with fingernail. Photo quality limits certainty.

Action

Collect samples for nursery/garden center positive ID. Several insecticides for scale: foliar sprays or systemic soil applications (root uptake). Accurate ID before treatment.
