Two-Spotted Spider Mites (Tetranychus urticae)

Spider mites are highly common in cruciferous crops like Prestar F1, especially during hot, dry conditions. They pierce plant cells to feed, creating characteristic fine silk webbing that can eventually envelop the cabbage leaves and cause stippling.

Very Common

Cabbage Webworm (Hellula rogatoria)

The larvae of the cabbage webworm feed on the foliage and often spin small webs to create a protective shelter. As they feed, they can leave behind fine silk structures around the damaged leaf edges.

Common

Diamondback Moth Larvae (Plutella xylostella)

While primarily known for skeletonizing leaves, these larvae can produce silk as they move and feed on cabbage plants. In heavy infestations, the accumulation of silk can appear as a fine web-like texture across damaged areas.

Common
