Red Twig Dogwood Covered in Flaky Gray Growth: Armored Scale Infestation

A SE Wisconsin gardener's three red twig dogwoods (2 years old) have two covered in what looks like flax seeds, gray twigs, not red. Growth doesn't brush off. Nearby birch and curly willow are fine. Plants were snow-covered all winter.

Diagnosis

Tom identified armored scale infestation. Advised contacting county extension horticultural agent with a sample; offered to get contact info with county name.

Armored scale appears as stationary, seed-like bumps; professional ID and treatment recommended.
