Powdery Mildew

This fungal disease is the most common cause of white, flour-like patches on Dianthus foliage. It thrives in high humidity and poor air circulation around the dense, matted growth of carpet varieties.

Mealybugs

These small insects secrete a white, waxy substance that can appear as powdery or cottony clumps on stems and leaf axils. In Dianthus, they often congregate in the tight crevices of the low-growing foliage.

Botrytis Blight (Early Stage)

While typically causing gray rot, early stages of Botrytis can manifest as light-colored, fuzzy patches on damp petals or foliage. This is common in 'Snow Carpet' if moisture lingers in the dense foliage canopy.
