Why does your Brassica Pigeon F1 Round Victoria have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are common pests in Brassica crops that feed on the underside of leaves, creating fine silk webbing to protect their colonies. This feeding causes stippling (tiny white dots) and can lead to leaf yellowing and premature senescence in cabbage heads.
While adults eat foliage, the larvae can create silk-like structures or disturbed patterns on leaf surfaces while feeding. In Victoria Round Cabbage, heavy larval feeding often leaves behind irregular holes and silken debris near the leaf edges.
In extremely humid environments, certain fungal pathogens can produce visible thread-like structures called mycelium that may resemble fine webbing. This is often accompanied by localized soft rot or water-soaked lesions on the cabbage leaves.
