Unpublished. Although X disease of stone fruits was initially believed to be the result of a virus, experts have now determined peach tree X disease is caused by a tiny parasitic organism (X disease phytoplasma). They are spread by insects through their feeding activities which inject the pathogen into the phloem of the plants. pp 237-258 | This starts with good weed removal practices and clearing brush that can host insect vectors. Fungi are the most common pathogens that infect many plant species.

Economically important phytoplasma diseases of fruit trees in Europe include apple proliferation (AP), pear de-cline (PD) and European stone fruit yellows (ESFY). Phytoplasmas are normally controlled by the breeding and planting of disease-resistant crop varieties (perhaps the most economically viable option) and by the control of insect vectors.

Phytoplasma live in the phloem cells of a plant and usually, but not always, cause disease symptoms. Well, first you need to understand the phytoplasma life cycle and how they are spread.
