Why does your White Cabbage Green Lunar F1 have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in warm, dry conditions and feed on the underside of cabbage leaves, injecting toxins that cause stippling. The 'fine webbing' is a characteristic silk web spun by the mites to protect themselves and their eggs.
Certain moth larvae create silk structures or webbing while feeding on the edges of brassica leaves. While they primarily cause defoliation, the presence of silken tunnels or fine webs among the cabbage heads is a primary sign.
In extremely dense cabbage plantings with poor airflow, fungal hyphae can sometimes resemble fine, fuzzy webbing on the leaf surface. This is often accompanied by signs of Botrytis (gray mold) in the tight crevices of the cabbage head.
