Peach X-Disease

Phytoplasma sp.

A lethal phytoplasma disease that affects peach trees throughout North America, transmitted by leafhoppers feeding on infected trees and wild chokecherry reservoirs. This systemic pathogen moves through phloem tissue causing progressive tree decline and death.

Peak Season: Leafhopper transmission occurs during active growing season. Symptoms develop 2 months after infection. Disease progression spans multiple years.

Identification & Symptoms

What to Look For

Leaves on isolated branches curl inward and develop irregular spots
Yellow to reddish-purple spots on leaves that later drop out
Leaves develop tattered 'shothole' appearance from dropped spots
Premature leaf fall starting at branch base, leaving tufts at tips
Premature fruit drop throughout the growing season
Progressive death of scaffold branches over 2-3 years
Chlorosis and stunting from progressive root loss

Potential Damage

Symptoms appear after about two months of growth
Progressive death of scaffold branches over 2-3 years
Complete tree death follows progressive branch mortality
Phloem death and inner bark destruction
Progressive root system loss and decline
Economic loss from premature fruit drop and tree mortality

Lifecycle

Transmitted by several species of leafhoppers that acquire the pathogen while feeding on infected peach or wild chokecherry. The leafhoppers require 2-3 weeks incubation period before they can transmit the disease to healthy trees. Wild chokecherry serves as an important natural reservoir.

Professional Treatment Approach

1

Remove and destroy infected trees to reduce pathogen sources

2

Control wild chokecherry reservoirs near orchards when possible

3

Apply systemic treatments like Fungisol for phloem health support

4

Monitor for early symptoms and rapid removal of affected trees

5

Professional diagnosis recommended for accurate identification

6

Preventive treatments may help tree vitality but cannot cure infection
