Description

Felt Gall Mites is caused by several mites, such as Aceria pseudoplatani which usually attacks Sycamore leaves, that causes Felt Gall. After biting the leaves the mites secrete a substance which causes the leaves to develop fine hairs which are usually white and resembles felt. It occurs in patches on the underside of the leaves and on some plants the felt like hairs can be reddish. With age these felt like patches of growth turn brown. Often the upper leaves are not affected, but there can be bulging on some leaves. Many plants and trees can be affected from Grape vines to apple trees.

Control

As the damage to the leaves are caused when the mites bites the leaves, getting rid of the mites will still leave the felt like lesions. Spraying with systemic insecticide may get rid of the mites, but usually the affect on the plant is minimal and can be ignored or scraped off if it is a light infection.
