Why does your Vigna radiata have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe presence of fine webbing on mung bean leaves is a classic sign of a spider mite infestation, where the mites spin webs to protect themselves and their eggs. These mites pierce plant cells to feed, leading to stippling and eventual leaf drop.
Low humidity and high temperatures often trigger rapid spider mite population explosions in Vigna radiata crops. The webbing is a defensive structure used by the mites to create a microclimate during dry spells.
While leaf miners primarily create visible 'trails' inside the leaf tissue, some species can cause secondary silken webbing on the surface as the plant reacts to the damage or if predatory mites are present.
