Why does your White Cabbage Shelta F1 have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The fine webbing is a classic sign of spider mites, which thrive in the warm, dry conditions often experienced by Brassica crops like Shelta F1 cabbage. These mites pierce plant cells to feed, leading to stippling and eventually structural web formation between leaves.
While they primarily cause 'windowpaning' on leaves, heavy infestations of young larvae can create silk-like webbing around feeding sites on the cabbage head or leaves. This species is a major pest specifically targeting cruciferous vegetables like White Cabbage.
Large numbers of looper larvae can produce silk webbing as they move between leaves while feeding on the nutrient-rich foliage of the Shelta F1 variety. The webbing is often accompanied by larger, irregular holes in the cabbage leaves.
