Leaf Galls

by admin

The unsightly bumps you may find on your tree(s) are nothing more than Leaf Gall. Galls develop from plant tissues that have been irritated by a parasitic organism. And, while this may sound like a big problem, galls are more unattractive than they are harmful. In fact, horticultural scholars suggest that galls rarely, if ever, affect the health of a plant.

The problem is purely aesthetic.

The most common found Gall-producing insects are: aphids, midges, wasps and mites. By the time a Gall is noticed on a tree, the insect is already protected from any chemical application. It is nearly impossible to treat large established trees.

The Audit of Plant Pathology Education & Training in the UK, published by the British Society for Plant Pathology, reports that plant pathology has been lost completely or greatly reduced at 11 universities and colleges.
