Why does your Capsicum frutescens have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are common pests for Capsicum frutescens that pierce stem and leaf tissues to suck sap, excreting a sugary substance known as honeydew. This honeydew creates the characteristic sticky coating on the leaves.
Scale insects attach themselves to the stems and leaf petioles of pepper plants, feeding on phloem sap and leaving behind sticky honeydew. Unlike aphids, these pests often appear as immobile, waxy bumps.
Whiteflies congregate on the undersides of Capsicum foliage and excrete honeydew as they feed. A sudden cloud of tiny white insects when the plant is disturbed is a strong indicator.
While not the primary cause of stickiness, sooty mold is a fungus that grows directly on the honeydew left by sap-sucking insects. It presents as a black, powdery coating that can block photosynthesis in your pepper plant.
