Scale - Soft
Soft scales (family Coccidae ) are sap-sucking pests that damage plants by feeding on phloem, leaving behind a sticky honeydew residue often associated with black sooty mold. Control measures include physical removal, promoting beneficial insects, and applying horticultural oils or systemic insecticides.
