Why does your Capsicum annuum Tango Deep Orange have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are small, soft-bodied insects that pierce the pepper's stems and leaves to suck out sap, excreting a sugary substance known as honeydew. This residue makes the 'Tango Deep Orange' foliage feel sticky to the touch.
Scale insects attach themselves to the pepper plant and feed on phloem sap, leaving behind a sticky honeydew coating. Unlike aphids, they appear as stationary, waxy bumps on the stems or leaf veins.
Whiteflies feed on the undersides of the pepper leaves, producing honeydew as a byproduct of their feeding process. This often results in a sticky film that can eventually lead to sooty mold growth.
While not the primary cause, sooty mold is a black fungus that grows specifically on the sticky honeydew left by sucking insects. It can coat the orange pepper leaves, reducing photosynthesis efficiency.
