Thrips are tiny insects causing discolored and deformed leaves in Winged elm. Severe infestations hinder growth and overall health, occasionally leading to severe damage.

Powdery mildew is a widespread fungal disease affecting Winged elm. This pathogen leaves a dusty white layer on leaves, drastically hindering photosynthesis, thus impairing the plant’s health and growth.

Gall disease in Winged elm is a pathological condition caused by infections and pests, resulting in bulbous deformities on the plant's stems and leaves. This disease can lead to stunted growth and weakened overall plant health.

Spider mite infestation on Winged elm leads to visible damage such as leaf discoloration and drop, which can severely affect the plant's health and aesthetic value.

Leafhopper disease affects Winged elm primarily through the feeding activity of leafhoppers, leading to symptoms such as yellowing and curling leaves. This condition can significantly impede the plant's growth and vigor.

Crown gall is a bacterial disease caused by Agrobacterium tumefaciens, posing a significant threat to Winged elm. It leads to abnormal tissue growth, inhibiting nutrients and water transport, causing overall decline and potential mortality of the plant.

Leaf beetle, a significant pest, targets Winged elm leading to severe defoliation and aesthetic damage. It is marked by its seasonal feeding frenzy especially during late spring and can affect tree health.

Dark blotch is a fungal disease impacting Winged elm, leading to necrosis and reduced vitality. It adversely affects both the aesthetic value and health of the trees, particularly marking the leaves with distinct dark patches.

Brown spot is a destructive fungal disease affecting Winged elm, causing brown blotches on leaves which can lead to defoliation and decreased plant health. Proper care and early detection are keys to controlling this condition.

Aphid infestation on Winged elm involves sap-sucking insects that weaken the plant by extracting vital fluids. This can result in myriad symptoms including leaf curl and stunted growth, significantly impacting the tree's health and aesthetic appeal.

Plant dried up' is a condition prevalent in Winged elm, leading to significant plant death and reduced growth. This disease caused by various environmental factors, affects almost every part with significant symptoms, and strengthens its grip during arid seasons.

Leaf yellowing is a common disease affecting Winged elm, characterized by discoloration that impedes photosynthesis and potentially weakens structural integrity.

Leaf tip withering

Leaf tip withering is a condition affecting Winged elm, characterized by the drying and browning of leaf tips. This ailment impairs photosynthesis, weakening the overall vitality of the plant.

Lichens, though often harmless, can impact Winged elm aesthetically and potentially weaken it by blocking light necessary for photosynthesis. This non-parasitic disease may affect growth but is generally non-lethal.

Yellow edges, a foliar disease, specifically impacts the appearance and vitality of Winged elm by causing distinct yellow discoloration along the leaf margins. The disease may reduce aesthetic value and overall health but is generally manageable with appropriate care.

Underwatering yellow

Underwatering is a non-infectious disease that affects Winged elm, leading to symptoms like wilting, yellowing, and growth retardation. This condition is generally characterized by inappropriate irrigation practices, notably insufficient water supply.

Weevil disease in Winged elm is primarily caused by beetle larvae that invade branches. This infestation leads to leaf damage, branch dieback, and in severe cases, weakened tree structure.

Leaf blight is a disease affecting Winged elm trees, leading to premature defoliation and yellowing of leaves. If unchecked, the disease can severely weaken the plant, compromising its yearly growth and making it susceptible to additional stresses.

Sapsucker damage

Sapsucker damage in Winged elm occurs when sapsucker birds drill holes into the bark, adversely affecting the tree's health by causing stress and vulnerability to other pathogens.

Moss is a non-parasitic organism that primarily affects Winged elm by inhibiting its growth and potentially causing bark decay. This disease is common in moist, shaded environments and can lead to aesthetic and physical damage to the tree.
