Why does your Arachis hypogaea have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are common pests of Arachis hypogaea that thrive in hot, dry conditions. They pierce the leaf cells to feed on sap, and the fine webbing is a characteristic defense and habitat structure created by the mite colonies.
While similar to the two-spotted variety, this specific mite species is highly aggressive in peanut crops during drought periods. The webbing often becomes denser as the infestation progresses, leading to chlorotic spotting on the underside of leaves.
Certain lepidopteran larvae feed on peanut foliage by pulling the leaf edges together with silk threads. This creates a webbing effect that can be mistaken for mite damage, though it usually results in folded or rolled leaves rather than fine, uniform webs.
