Two-Spotted Spider Mite Infestation

Spider mites are common pests on brassicas like White Cabbage Ippon F1, especially in hot, dry conditions. They pierce plant cells to suck sap, leaving behind fine silk webbing as they build colonies across the leaf surfaces.

Very Common

High Humidity/Microclimate Fungal Growth

While less common as 'webbing', certain fungal hyphae can appear as fine, thread-like structures on the surface of cabbage leaves in extremely stagnant, humid environments.

Common

How to confirm: Check if the webbing feels more like a fuzzy mold and if there is a musty odor near the base of the plant.
