Why does your Capsicum cubana Deep Orange have white powder? Diagnose the cause and fix it with our step-by-step guide.
This fungal disease manifests as white, flour-like patches on the leaves of Capsicum species. It thrives in high humidity and moderate temperatures, often inhibiting photosynthesis and causing leaf curling.
Small, white flying insects can congregate on the undersides of pepper leaves, leaving behind tiny white egg clusters or excrement that looks like dust. They suck sap from the plant, which can lead to yellowing.
These sap-sucking insects produce a white, waxy, cottony substance that can appear as white powder or fuzz on stems and leaf axils of the Cuban Pepper.
Excessive use of fertilizers or hard water can leave white, crusty mineral residues on the leaf surfaces or at the edges of the pot.
