Two-Spotted Spider Mite Infestation

High Humidity and Microclimate Fungal Growth

While less common than mites, extreme localized humidity trapped within dense Chrysanthemum foliage can cause fungal hyphae to appear as fine, hair-like structures. This is usually accompanied by leaf spotting or botrytis.

Common
