Why does your Cucumis melo have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are the most frequent cause of fine silk webbing on melon leaves, especially in hot, dry conditions. They pierce plant cells to feed, leading to stippling and eventual leaf drop.
In melon production, these mites thrive when humidity is low, creating dense webs that protect the colony from predators and desiccation. This webbing can eventually cover entire fruit clusters.
While less common than mites, extremely high humidity in a melon canopy can cause fungal hyphae to appear as fine, thread-like structures on leaf surfaces. This is often accompanied by moisture droplets.
