Which are key damage symptoms caused by aphids?

Explanation:
Aphids damage ornamental and turf plants mainly by sucking sap from new growth. This feeding distorts growth, causing curling, stunted, or misshapen shoots. In addition, aphids excrete a sugary honeydew that coats leaves and stems, which often supports the growth of black sooty mold. The combination of distorted growth, honeydew, and sooty mold is characteristic of aphid injury. Wilting from root rot, leaf yellowing, or stem dieback point to other problems such as root pathogens, general stress, or pests/diseases affecting woody tissue, not the typical aphid damage pattern.
