Aphid Infestation

Aphids are small, soft-bodied insects that pierce the Gerbera's tender stems and leaves to suck sap, excreting a sugary substance known as honeydew. This honeydew creates the characteristic sticky residue on the foliage.

Very Common

Scale Insects

Common

Common

Sooty Mold Development

While not the primary cause, sooty mold is a black fungus that grows specifically on the sticky honeydew left by sucking insects. It can eventually coat the Peach 5089 leaves, reducing photosynthesis.

Common

How to confirm: Look for a dark, powdery, or soot-like coating covering the areas where the leaves feel most sticky.
