Aphid Infestation

Aphids are sap-sucking insects that pierce the tender stems and leaves of Gerbera daisies to feed, excreting a sugary substance known as honeydew. This substance creates the characteristic sticky film on the leaf surfaces.

Very Common

Sooty Mold (Secondary Symptom)

While not the primary cause of stickiness, Sooty Mold is a black fungus that grows specifically on the honeydew left by pests. It covers the leaves in a dark, velvety layer, which can interfere with the plant's photosynthesis.
