Галловые клещи винограда

Grape gall mites are a species of tiny mites that dwell inside cracks along stems and under buds during the winter and emerge during the beginning of vegetative growth. Grape gall mites feed on the underside of leaves and cause the formation of thick white hair-like bunches that turn red-brown as time progresses. The most noticeable symptom of an infestation is the creation of galls on the upper side of leaves. Grape gall mites rarely cause significant damage to the vines, although it may cause the overall appearance of plants to be less aesthetic.
