What is leaf curl disease?

Peach leaf curl, also known as leaf curl, is a disease caused by the fungus Taphrina deformans.

How do you control leaf curl virus?

Chemical control: Imidacloprid should be sprayed on the entire plant and below the leaves; eggs and flies are often found below the leaves. Spray every 14-21 days and rotate on a monthly basis with Abamectin so that the whiteflies do not build-up resistance to chemicals.

Can leaf curl spread to other plants?

The fungus causes the growing cells at the leaf margins to multiply quickly and randomly which results in the curled and distorted appearance. The fungus then wastes no time producing spores on the surface of the leaf that spread to other leaves and fruits on your tree or other trees in the area.
