Apple - Soft Scales

Prepared by Frank Zalom and Mark Bell - UC Davis International Programs Office (2008) "About Soft Scales Soft scales reproduce without mating and lay many eggs. Soft scales may settle on leaves, twigs, branches, and trunk, and less often on fruit. Damage Soft scale reduces tree vigor by extracting plant sap from leaves, twigs, and branches. Soft scales secrete honeydew, which promotes the growth of sooty mold and downgrades fruit quality. Heavy infestations may cause leaf and fruit drop, and twig dieback. "
