Lavender Decline in France Is Associated with Chronic Infection by Lavender-Specific Strains of "Candidatus Phytoplasma solani".

ABSTRACT: Lavender decline compromises French lavender production, and preliminary data have suggested the involvement of "Candidatus Phytoplasma solani" in the etiology of the disease. In order to evaluate the epidemiological role of "Ca Phytoplasma solani," a 3-year survey was conducted in southeastern France. "Ca Phytoplasma solani" was detected in 19 to 56% of the declining plants, depending on seasons and cultivars, and its prevalence was correlated with symptom severity. Autumn was more favorable than spring for phytoplasma detection, and "Ca Phytoplasma solani" incidence was higher in Lavandula angustifolia than in Lavandula intermedia hybrids. Detection of the phytoplasma fluctuated over months, supporting the chronicity of infection. Three "Ca
