Monitor for Fletcher scale on the undersides of the twigs of Taxus. Pick off the brown scale and look for the white, powdery eggs. A second application may be necessary after 10 days. Monitor for crawlers of Euonymus scale over the coming weeks. Plants near buildings or in locations with warmer microclimates should be monitored first.
Nymphs are pale green in colour.
They feed on the underside of leaves. First feeding damage looks like small, pin-point yellow spots on the upper surface. Crawlers hatch over an extended period of time. Treat once hatch is observed and follow with a second treatment as required. Systemic insecticides are more effective.
